Clinical Trial Experience in Adult Patients Clinical trials enrolled 1,864 adult patients treated with daptomycin for injection and 1,416 treated with comparator. Complicated Skin and Skin Structure Infection Trials in Adults In Phase 3 complicated skin and skin structure infection (cSSSI) trials in adult patients, daptomycin for injection was discontinued in 15/534 (2.8%) patients due to an adverse reaction, while comparator was discontinued in 17/558 (3.0%) patients. The rates of the most common adverse reactions, organized by body system, observed in adult patients with cSSSI (receiving 4 mg/kg daptomycin for injection) are displayed in Table 6 . Table 6.

Serious Gram-negative infections (including bloodstream infections) were reported in 10/120 (8.3%) daptomycin for injection-treated patients and 0/115 comparator-treated patients. Comparator-treated patients received dual therapy that included initial gentamicin for 4 days. Infections were reported during treatment and during early and late follow-up. Gram-negative infections included cholangitis, alcoholic pancreatitis, sternal osteomyelitis/mediastinitis, bowel infarction, recurrent Crohn’s disease, recurrent line sepsis, and recurrent urosepsis caused by a number of different Gram-negative bacteria. The rates of the most common adverse reactions, organized by System Organ Class (SOC), observed in adult patients with S. aureus bacteremia/endocarditis (receiving 6 mg/kg daptomycin for injection) are displayed in Table 7 .

These differences were due to lack of therapeutic effectiveness of daptomycin for injection in the treatment of CAP in patients experiencing these adverse events [see Indications and Usage (1.4) ]. Laboratory Changes in Adults Complicated Skin and Skin Structure Infection Trials in Adults In Phase 3 cSSSI trials of adult patients receiving daptomycin for injection at a dose of 4 mg/kg, elevations in CPK were reported as clinical adverse events in 15/534 (2.8%) daptomycin for injection-treated patients, compared with 10/558 (1.8%) comparator-treated patients. Of the 534 patients treated with daptomycin for injection, 1 (0.2%) had symptoms of muscle pain or weakness associated with CPK elevations to greater than 4 times the upper limit of normal (ULN). The symptoms resolved within 3 days and CPK returned to normal within 7 to 10 days after treatment was discontinued [see Warnings and Precautions (5.2) ] . Table 8 summarizes the CPK shifts from Baseline through End of Therapy in the cSSSI adult trials. Table 8.

S. aureus Bacteremia/Endocarditis Trial in Adults In the S. aureus bacteremia/endocarditis trial in adult patients, at a dose of 6 mg/kg, 11/120 (9.2%) daptomycin for injection-treated patients, including two patients with baseline CPK levels >500 U/L, had CPK elevations to levels >500 U/L, compared with 1/116 (0.9%) comparator-treated patients. Of the 11 daptomycin for injection-treated patients, 4 had prior or concomitant treatment with an HMG-CoA reductase inhibitor. Three of these 11 daptomycin for injection-treated patients discontinued therapy due to CPK elevation, while the one comparator-treated patient did not discontinue therapy [see Warnings and Precautions (5.2) ]. Clinical Trial Experience in Pediatric Patients Complicated Skin and Skin Structure Infection Trial in Pediatric Patients The safety of daptomycin for injection was evaluated in one clinical trial (in cSSSI), which included 256 pediatric patients (1 to 17 years of age) treated with intravenous daptomycin for injection and 133 patients treated with comparator agents. Patients were given age-dependent doses once daily for a treatment period of up to 14 days (median treatment period was 3 days). The doses given by age group were as follows: 10 mg/kg for 1 to < 2 years, 9 mg/kg for 2 to 6 years, 7 mg/kg for 7 to 11 years and 5 mg/kg for 12 to 17 years of age [see Clinical Studies (14) ] . Patients treated with daptomycin for injection were (51%) male, (49%) female and (46%) Caucasian and (32%) Asian. Adverse Reactions Leading to Discontinuation In the cSSSI study, daptomycin for injection was discontinued in 7/256 (2.7%) patients due to an adverse reaction, while comparator was discontinued in 7/133 (5.3%) patients. Most Common Adverse Reactions The rates of the most common adverse reactions, organized by body system, observed in these pediatric patients with cSSSI are displayed in Table 9 . Table 9.

S. aureus Bacteremia Trial in Pediatric Patients The safety of daptomycin for injection was evaluated in one clinical trial (in S. aureus bacteremia), which treated 55 pediatric patients with intravenous daptomycin for injection and 26 patients with comparator agents. Patients were given age-dependent doses once daily for a treatment period of up to 42 days (mean duration of IV treatment was 12 days). The doses by age group were as follows: 12 mg/kg for 1 to <6 years, 9 mg/kg for 7 to 11 years and 7 mg/kg for 12 to 17 years of age [see Clinical Studies (14) ] . Patients treated with daptomycin for injection were (69%) male and (31%) female. No patients 1 to <2 years of age were enrolled. Adverse Reactions Leading to Discontinuation In the bacteremia study, daptomycin for injection was discontinued in 3/55 (5.5%) patients due to an adverse reaction, while comparator was discontinued in 2/26 (7.7%) patients. Most Common Adverse Reactions The rates of the most common adverse reactions, organized by body system, observed in these pediatric patients with bacteremia are displayed in Table 10 . Table 10.

Because these reactions are reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency or establish a causal relationship to drug exposure. Blood and lymphatic system disorders: anemia, thrombocytopenia General and administration site conditions: pyrexia Immune System Disorders: anaphylaxis; hypersensitivity reactions, including angioedema, pruritus, hives, shortness of breath, difficulty swallowing, truncal erythema, and pulmonary eosinophilia [see Contraindications (4) and Warnings and Precautions (5.1) ] Infections and Infestations: Clostridioides difficile –associated diarrhea [see Warnings and Precautions (5.8) ] Laboratory Investigations: platelet count decreased Musculoskeletal Disorders: myoglobin increased; rhabdomyolysis (some reports involved patients treated concurrently with daptomycin for injection and HMG-CoA reductase inhibitors) [see Warnings and Precautions (5.2) , Drug Interactions (7.1) , and Clinical Pharmacology (12.3) ] Respiratory, Thoracic, and Mediastinal Disorders: cough, eosinophilic pneumonia, organizing pneumonia [see Warnings and Precautions (5.3) ] Nervous System Disorders: peripheral neuropathy [see Warnings and Precautions (5.6) ] Skin and Subcutaneous Tissue Disorders: serious skin reactions, including drug reaction with eosinophilia and systemic symptoms (DRESS), vesiculobullous rash (with or without mucous membrane involvement, including Stevens-Johnson syndrome [SJS] and toxic epidermal necrolysis [TEN]), and acute generalized exanthematous pustulosis [see Warnings and Precautions (5.4) ] Gastrointestinal Disorders: nausea, vomiting Renal and urinary disorders: acute kidney injury, renal insufficiency, renal failure, and tubulointerstitial nephritis (TIN) [see Warnings and Precautions (5.5) ] Special Senses: visual disturbances"}', 'drug_interactions': '{"7 DRUG INTERACTIONS 7.1 HMG-CoA Reductase Inhibitors In healthy adult subjects, concomitant administration of daptomycin for injection and simvastatin had no effect on plasma trough concentrations of simvastatin, and there were no reports of skeletal myopathy [see Clinical Pharmacology (12.3) ]. However, inhibitors of HMG-CoA reductase may cause myopathy, which is manifested as muscle pain or weakness associated with elevated levels of creatine phosphokinase (CPK). In the adult Phase 3 S. aureus bacteremia/endocarditis trial, some patients who received prior or concomitant treatment with an HMG-CoA reductase inhibitor developed elevated CPK [see Adverse Reactions (6.1) ]. Experience with the coadministration of HMG-CoA reductase inhibitors and daptomycin for injection in patients is limited; therefore, consideration should be given to suspending use of HMG-CoA reductase inhibitors temporarily in patients receiving Daptomycin in Sodium Chloride Injection. 7.2 Drug-Laboratory Test Interactions Clinically relevant plasma concentrations of daptomycin have been observed to cause a significant concentration-dependent false prolongation of prothrombin time (PT) and elevation of International Normalized Ratio (INR) when certain recombinant thromboplastin reagents are utilized for the assay. The possibility of an erroneously elevated PT/INR result due to interaction with a recombinant thromboplastin reagent may be minimized by drawing specimens for PT or INR testing near the time of trough plasma concentrations of daptomycin. However, sufficient daptomycin concentrations may be present at trough to cause interaction. If confronted with an abnormally high PT/INR result in a patient being treated with Daptomycin in Sodium Chloride Injection, it is recommended that clinicians: 1. Repeat the assessment of PT/INR, requesting that the specimen be drawn just prior to the next Daptomycin in Sodium Chloride Injection dose (i.e., at trough concentration). If the PT/INR value obtained at trough remains substantially elevated above what would otherwise be expected, consider evaluating PT/INR utilizing an alternative method. 2. Evaluate for other causes of abnormally elevated PT/INR results."}', 'indications_and_usage': '{"1 INDICATIONS AND USAGE Daptomycin in Sodium Chloride Injection is a lipopeptide antibacterial indicated for the treatment of: • Complicated skin and skin structure infections (cSSSI) in adult and pediatric patients (1 to 17 years of age) for whom appropriate dosing can be achieved ( 1.1 ) and, • Staphylococcus aureus bloodstream infections (bacteremia), in adult patients for whom appropriate dosing can be achieved, including those with right-sided infective endocarditis, ( 1.2 ) • Staphylococcus aureus bloodstream infections (bacteremia) in pediatric patients (1 to 17 years of age) for whom appropriate dosing can be achieved. ( 1.3 ) Limitations of Use • Daptomycin in Sodium Chloride Injection is not indicated for the treatment of pneumonia. ( 1.4 ) • Daptomycin in Sodium Chloride Injection is not indicated for the treatment of left-sided infective endocarditis due to S. aureus. ( 1.4 ) • Daptomycin in Sodium Chloride Injection is not recommended in pediatric patients younger than one year of age due to the risk of potential effects on muscular, neuromuscular, and/or nervous systems (either peripheral and/or central) observed in neonatal dogs. ( 1.4 ) To reduce the development of drug-resistant bacteria and maintain the effectiveness of Daptomycin in Sodium Chloride Injection and other antibacterial drugs, Daptomycin in Sodium Chloride Injection should be used to treat or prevent infections that are proven or strongly suspected to be caused by bacteria. ( 1.5 ) 1.1 Complicated Skin and Skin Structure Infections (cSSSI) Daptomycin in Sodium Chloride Injection is indicated for the treatment of adult and pediatric patients (1 to 17 years of age) for whom appropriate dosing can be achieved, with complicated skin and skin structure infections (cSSSI) caused by susceptible isolates of the following Gram-positive bacteria: Staphylococcus aureus (including methicillin-resistant isolates), Streptococcus pyogenes, Streptococcus agalactiae, Streptococcus dysgalactiae subsp. equisimilis, and Enterococcus faecalis (vancomycin-susceptible isolates only). 1.2 Staphylococcus aureus Bloodstream Infections (Bacteremia) in Adult Patients, Including Those with Right-Sided Infective Endocarditis, Caused by Methicillin-Susceptible and Methicillin-Resistant Isolates Daptomycin in Sodium Chloride Injection is indicated for the treatment of adult patients for whom appropriate dosing can be achieved, with Staphylococcus aureus bloodstream infections (bacteremia), including adult patients with right-sided infective endocarditis, caused by methicillin-susceptible and methicillin-resistant isolates. 1.3 Staphylococcus aureus Bloodstream Infections (Bacteremia) in Pediatric Patients (1 to 17 Years of Age) Daptomycin in Sodium Chloride Injection is indicated for the treatment of pediatric patients (1 to 17 years of age) for whom appropriate dosing can be achieved with Staphylococcus aureus bloodstream infections (bacteremia). 1.4 Limitations of Use Daptomycin in Sodium Chloride Injection is not indicated for the treatment of pneumonia. Daptomycin in Sodium Chloride Injection is not indicated for the treatment of left-sided infective endocarditis due to S. aureus . The clinical trial of daptomycin for injection in adult patients with S. aureus bloodstream infections included limited data from patients with left-sided infective endocarditis; outcomes in these patients were poor [see Clinical Studies (14.2) ]. Daptomycin for injection has not been studied in patients with prosthetic valve endocarditis. Daptomycin in Sodium Chloride Injection is not recommended in pediatric patients younger than 1 year of age due to the risk of potential effects on muscular, neuromuscular, and/or nervous systems (either peripheral and/or central) observed in neonatal dogs [see Warnings and Precautions (5.7) and Nonclinical Toxicology (13.2) ] . 1.5 Usage Appropriate specimens for microbiological examination should be obtained in order to isolate and identify the causative pathogens and to determine their susceptibility to daptomycin. To reduce the development of drug-resistant bacteria and maintain the effectiveness of Daptomycin in Sodium Chloride Injection and other antibacterial drugs, Daptomycin in Sodium Chloride Injection should be used only to treat or prevent infections that are proven or strongly suspected to be caused by susceptible bacteria. When culture and susceptibility information is available, it should be considered in selecting or modifying antibacterial therapy. In the absence of such data, local epidemiology and susceptibility patterns may contribute to the empiric selection of therapy. Empiric therapy may be initiated while awaiting test results."}', 'warnings_and_cautions': '{"5 WARNINGS AND PRECAUTIONS • Anaphylaxis/hypersensitivity reactions (including life-threatening): Discontinue Daptomycin in Sodium Chloride Injection and treat signs/symptoms. (5.1) • Myopathy and rhabdomyolysis: Monitor CPK levels and follow muscle pain or weakness; if elevated CPK or myopathy occurs, consider discontinuation of Daptomycin in Sodium Chloride Injection. (5.2) • Eosinophilic pneumonia: Discontinue Daptomycin in Sodium Chloride Injection and consider treatment with systemic steroids. (5.3) • Drug Reaction with Eosinophilia and Systemic Symptoms (DRESS): Discontinue Daptomycin in Sodium Chloride Injection and institute appropriate treatment. (5.4) • Tubulointerstitial Nephritis (TIN): Discontinue Daptomycin in Sodium Chloride Injection and institute appropriate treatment. (5.5) • Peripheral neuropathy: Monitor for neuropathy and consider discontinuation. (5.6) • Potential nervous system and/or muscular system effects in pediatric patients younger than 12 months: Avoid use of Daptomycin in Sodium Chloride Injection in this age group. (5.7) • Clostridioides difficile– associated diarrhea: Evaluate patients if diarrhea occurs. (5.8) • Persisting or relapsing S. aureus bacteremia/endocarditis: Perform susceptibility testing and rule out sequestered foci of infection. (5.9) • Decreased efficacy was observed in adult patients with moderate baseline renal impairment. (5.10) 5.1 Anaphylaxis/Hypersensitivity Reactions Anaphylaxis/hypersensitivity reactions have been reported with the use of antibacterial agents, including daptomycin for injection, and may be life-threatening. If an allergic reaction to Daptomycin in Sodium Chloride Injection occurs, discontinue the drug and institute appropriate therapy [see Adverse Reactions (6.2) ]. 5.2 Myopathy and Rhabdomyolysis Myopathy, defined as muscle aching or muscle weakness in conjunction with increases in creatine phosphokinase (CPK) values to greater than 10 times the upper limit of normal (ULN), has been reported with the use of daptomycin for injection. Rhabdomyolysis, with or without acute renal failure, has been reported [see Adverse Reactions (6.2) ] . Patients receiving Daptomycin in Sodium Chloride Injection should be monitored for the development of muscle pain or weakness, particularly of the distal extremities. In patients who receive Daptomycin in Sodium Chloride Injection, CPK levels should be monitored weekly, and more frequently in patients who received recent prior or concomitant therapy with an HMG-CoA reductase inhibitor or in whom elevations in CPK occur during treatment with Daptomycin in Sodium Chloride Injection. In adult patients with renal impairment, both renal function and CPK should be monitored more frequently than once weekly [see Use in Specific Populations (8.6) and Clinical Pharmacology (12.3) ]. In Phase 1 studies and Phase 2 clinical trials in adults, CPK elevations appeared to be more frequent when daptomycin for injection was dosed more than once daily. Therefore, Daptomycin in Sodium Chloride Injection should not be dosed more frequently than once a day. Daptomycin in Sodium Chloride Injection should be discontinued in patients with unexplained signs and symptoms of myopathy in conjunction with CPK elevations to levels >1,000 U/L (~5× ULN), and in patients without reported symptoms who have marked elevations in CPK, with levels >2,000 U/L (≥10× ULN). In addition, consideration should be given to suspending agents associated with rhabdomyolysis, such as HMG-CoA reductase inhibitors, temporarily in patients receiving Daptomycin in Sodium Chloride Injection [see Drug Interactions (7.1) ]. 5.3 Eosinophilic Pneumonia Eosinophilic pneumonia has been reported in patients receiving daptomycin for injection [see Adverse Reactions (6.2) ]. In reported cases associated with daptomycin for injection, patients developed fever, dyspnea with hypoxic respiratory insufficiency, and diffuse pulmonary infiltrates or organizing pneumonia. In general, patients developed eosinophilic pneumonia 2 to 4 weeks after starting daptomycin for injection and improved when daptomycin for injection was discontinued and steroid therapy was initiated. Recurrence of eosinophilic pneumonia upon re-exposure has been reported. Patients who develop these signs and symptoms while receiving Daptomycin in Sodium Chloride Injection should undergo prompt medical evaluation, and Daptomycin in Sodium Chloride Injection should be discontinued immediately. Treatment with systemic steroids is recommended. 5.4 Drug Reaction with Eosinophilia and Systemic Symptoms (DRESS) DRESS has been reported in post-marketing experience with daptomycin for injection [see Adverse Reactions (6.2) ] . Patients who develop skin rash, fever, peripheral eosinophilia, and systemic organ (for example, hepatic, renal, pulmonary) impairment while receiving Daptomycin in Sodium Chloride Injection should undergo medical evaluation. If DRESS is suspected, discontinue Daptomycin in Sodium Chloride Injection promptly and institute appropriate treatment. 5.5 Tubulointerstitial Nephritis (TIN) TIN has been reported in post-marketing experience with daptomycin for injection [see Adverse Reactions (6.2) ] . Patients who develop new or worsening renal impairment while receiving Daptomycin in Sodium Chloride Injection should undergo medical evaluation. If TIN is suspected, discontinue Daptomycin in Sodium Chloride Injection promptly and institute appropriate treatment. 5.6 Peripheral Neuropathy Cases of peripheral neuropathy have been reported during the daptomycin for injection postmarketing experience [see Adverse Reactions (6.2) ]. Therefore, physicians should be alert to signs and symptoms of peripheral neuropathy in patients receiving Daptomycin in Sodium Chloride Injection. Monitor for neuropathy and consider discontinuation. 5.7 Potential Nervous System and/or Muscular System Effects in Pediatric Patients Younger than 12 Months Avoid use of Daptomycin in Sodium Chloride Injection in pediatric patients younger than 12 months due to the risk of potential effects on muscular, neuromuscular, and/or nervous systems (either peripheral and/or central) observed in neonatal dogs with intravenous daptomycin [see Nonclinical Toxicology (13.2) ]. 5.8 Clostridioides difficile -Associated Diarrhea Clostridioides difficile –associated diarrhea (CDAD) has been reported with the use of nearly all systemic antibacterial agents, including daptomycin for injection, and may range in severity from mild diarrhea to fatal colitis [see Adverse Reactions (6.2) ]. Treatment with antibacterial agents alters the normal flora of the colon, leading to overgrowth of C. difficile . C. difficile produces toxins A and B, which contribute to the development of CDAD. Hypertoxin-producing strains of C. difficile cause increased morbidity and mortality, since these infections can be refractory to antimicrobial therapy and may require colectomy. CDAD must be considered in all patients who present with diarrhea following antibacterial use. Careful medical history is necessary because CDAD has been reported to occur more than 2 months after the administration of antibacterial agents. If CDAD is suspected or confirmed, ongoing antibacterial use not directed against C. difficile may need to be discontinued. Appropriate fluid and electrolyte management, protein supplementation, antibacterial treatment of C. difficile , and surgical evaluation should be instituted as clinically indicated. 5.9 Persisting or Relapsing S. aureus Bacteremia/Endocarditis Patients with persisting or relapsing S. aureus bacteremia/endocarditis or poor clinical response should have repeat blood cultures. If a blood culture is positive for S. aureus , minimum inhibitory concentration (MIC) susceptibility testing of the isolate should be performed using a standardized procedure, and diagnostic evaluation of the patient should be performed to rule out sequestered foci of infection. Appropriate surgical intervention (e.g., debridement, removal of prosthetic devices, valve replacement surgery) and/or consideration of a change in antibacterial regimen may be required. Failure of treatment due to persisting or relapsing S. aureus bacteremia/endocarditis may be due to reduced daptomycin susceptibility (as evidenced by increasing MIC of the S. aureus isolate) [see Clinical Studies (14.2) ]. 5.10 Decreased Efficacy in Patients with Moderate Baseline Renal Impairment Limited data are available from the two Phase 3 complicated skin and skin structure infection (cSSSI) trials regarding clinical efficacy of daptomycin for injection treatment in adult patients with creatinine clearance (CL CR ) <50 mL/min; only 31/534 (6%) patients treated with daptomycin for injection in the intent-to-treat (ITT) population had a baseline CL CR <50 mL/min. Table 4 shows the number of adult patients by renal function and treatment group who were clinical successes in the Phase 3 cSSSI trials. Table 4.

Cough, Breathlessness or Fever (Eosinophilic Pneumonia) Advise patients to report any symptoms of cough, breathlessness, or fever [see Warnings and Precautions (5.3 )]. C. difficile -Associated Diarrhea (CDAD) Advise patients that diarrhea is a common problem caused by antibacterials including daptomycin for injection that usually ends when the antibacterial is discontinued. Sometimes after starting treatment with antibacterials, including Daptomycin in Sodium Chloride Injection, patients can develop watery and bloody stools (with or without stomach cramps and fever), even as late as 2 or more months after having received the last dose of the antibacterial. If this occurs, patients should contact their physician as soon as possible [see Warnings and Precautions (5.8) ]. Antibacterial Resistance Patients should be counseled that antibacterial drugs, including Daptomycin in Sodium Chloride Injection, should be used to treat bacterial infections. They do not treat viral infections (e.g., the common cold). When Daptomycin in Sodium Chloride Injection is prescribed to treat a bacterial infection, patients should be told that although it is common to feel better early in the course of therapy, the medication should be administered exactly as directed. Skipping doses or not completing the full course of therapy may (1) decrease the effectiveness of the immediate treatment and (2) increase the likelihood that bacteria will develop resistance and will not be treatable by Daptomycin in Sodium Chloride Injection or other antibacterial drugs in the future.

In animal reproduction studies performed in rats and rabbits daptomycin was administered intravenously during organogenesis at doses 2 and 4–times, respectively, the recommended 6 mg/kg human dose (on a body surface area basis). No evidence of adverse developmental outcomes was observed. The background risk of major birth defects and miscarriage for the indicated population is unknown. All pregnancies have a background risk of birth defect, loss, or other adverse outcomes. In the U.S. general population, the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies is 2-4% and 15-20%, respectively.

Patients with a history of penicillamine-related aplastic anemia or agranulocytosis should not be restarted on penicillamine (see WARNINGS and ADVERSE REACTIONS ). Because of its potential for causing renal damage, penicillamine should not be administered to rheumatoid arthritis patients with a history or other evidence of renal insufficiency."}', 'adverse_reactions': '{"ADVERSE REACTIONS To report SUSPECTED ADVERSE REACTIONS, contact Lupin Pharmaceuticals Inc. at 1-800-399-2561 or FDA at 1-800-FDA-1088 or www.fda.gov/medwatch. Penicillamine is a drug with a high incidence of untoward reactions, some of which are potentially fatal. Therefore, it is mandatory that patients receiving penicillamine therapy remain under close medical supervision throughout the period of drug administration (see WARNINGS and PRECAUTIONS ). Reported incidences (%) for the most commonly occurring adverse reactions in rheumatoid arthritis patients are noted, based on 17 representative clinical trials reported in the literature (1270 patients). Allergic Generalized pruritus, early and late rashes (5%), pemphigus (see WARNINGS ), and drug eruptions which may be accompanied by fever, arthralgia, or lymphadenopathy have occurred (see WARNINGS and PRECAUTIONS ). Some patients may show a lupus erythematosus-like syndrome similar to drug-induced lupus produced by other pharmacological agents (see PRECAUTIONS ). Urticaria and exfoliative dermatitis have occurred. Thyroiditis has been reported; hypoglycemia in association with anti-insulin antibodies has been reported. These reactions are extremely rare. Some patients may develop a migratory polyarthralgia, often with objective synovitis (see DOSAGE AND ADMINISTRATION ). Gastrointestinal Anorexia, epigastric pain, nausea, vomiting, or occasional diarrhea may occur (17%). Isolated cases of reactivated peptic ulcer have occurred, as have hepatic dysfunction and pancreatitis. Intrahepatic cholestasis and toxic hepatitis have been reported rarely. There have been a few reports of increased serum alkaline phosphatase, lactic dehydrogenase, and positive cephalin flocculation and thymol turbidity tests. Some patients may report a blunting, diminution, or total loss of taste perception (12%); or may develop oral ulcerations. Although rare, cheilosis, glossitis, and gingivo-stomatitis have been reported (see PRECAUTIONS ). Gastrointestinal side effects are usually reversible following cessation of therapy. Hematological Penicillamine can cause bone marrow depression (see WARNINGS ). Leukopenia (2%) and thrombocytopenia (4%) have occurred. Fatalities have been reported as a result of thrombocytopenia, agranulocytosis, aplastic anemia, and sideroblastic anemia. Thrombotic thrombocytopenic purpura, hemolytic anemia, red cell aplasia, monocytosis, leukocytosis, eosinophilia, and thrombocytosis have also been reported. Renal Patients on penicillamine therapy may develop proteinuria (6%) and/or hematuria which, in some, may progress to the development of the nephrotic syndrome as a result of an immune complex membranous glomerulopathy (see WARNINGS ). Central Nervous System Tinnitus, optic neuritis, and peripheral sensory and motor neuropathies (including polyradiculoneuropathy, i.e., Guillain-Barre Syndrome) have been reported. Muscular weakness may or may not occur with the peripheral neuropathies. Neuromuscular Myasthenia gravis (see WARNINGS ). Other Adverse reactions that have been reported rarely include thrombophlebitis; hyperpyrexia (see PRECAUTIONS ); falling hair or alopecia; lichen planus; polymyositis; dermatomyositis; mammary hyperplasia; elastosis perforans serpiginosa; toxic epidermal necrolysis; anetoderma (cutaneous macular atrophy); and Goodpasture\'s syndrome, a severe and ultimately fatal glomerulonephritis associated with intra-alveolar hemorrhage (see WARNINGS ). Fatal renal vasculitis has also been reported. Allergic alveolitis, obliterative bronchiolitis, interstitial pneumonitis, and pulmonary fibrosis have been reported in patients with severe rheumatoid arthritis, some of whom were receiving penicillamine. Bronchial asthma also has been reported. Increased skin friability, excessive wrinkling of skin, and development of small, white papules at venipuncture and surgical sites have been reported (see PRECAUTIONS ). The chelating action of the drug may cause increased excretion of other heavy metals such as zinc, mercury, and lead. There have been reports associating penicillamine with leukemia. However, circumstances involved in these reports are such that a cause and effect relationship to the drug has not been established."}', 'drug_interactions': None, 'indications_and_usage': '{"INDICATIONS Penicillamine tablets are indicated in the treatment of Wilson\'s disease, cystinuria, and in patients with severe, active rheumatoid arthritis who have failed to respond to an adequate trial of conventional therapy. Available evidence suggests that penicillamine tablets are not of value in ankylosing spondylitis. Wilson’s Disease Wilson\'s disease (hepatolenticular degeneration) results from the interaction of an inherited defect and an abnormality in copper metabolism. The metabolic defect, which is the consequence of the autosomal inheritance of one abnormal gene from each parent, manifests itself in a greater positive copper balance than normal. As a result, copper is deposited in several organs and appears eventually to produce pathologic effects most prominently seen in the brain, where degeneration is widespread; in the liver, where fatty infiltration, inflammation, and hepatocellular damage progress to postnecrotic cirrhosis; in the kidney, where tubular and glomerular dysfunction results; and in the eye, where characteristic corneal copper deposits are known as Kayser-Fleischer rings. Two types of patients require treatment for Wilson\'s disease: (1) the symptomatic, and (2) the asymptomatic in whom it can be assumed the disease will develop in the future if the patient is not treated. Diagnosis, suspected on the basis of family or individual history, physical examination, or a low serum concentration of ceruloplasmin*, is confirmed by the demonstration of Kayser-Fleischer rings or, particularly in the asymptomatic patient, by the quantitative demonstration in a liver biopsy specimen of a concentration of copper in excess of 250 mcg/g dry weight. Treatment has two objectives: (1) to minimize dietary intake and absorption of copper. (2) to promote excretion of copper deposited in tissues. The first objective is attained by a daily diet that contains no more than one or two milligrams of copper. Such a diet should exclude, most importantly, chocolate, nuts, shellfish, mushrooms, liver, molasses, broccoli, and cereals enriched with copper, and be composed to as great an extent as possible of foods with a low copper content. Distilled or demineralized water should be used if the patient\'s drinking water contains more than 0.1 mg of copper per liter. For the second objective, a copper chelating agent is used. In symptomatic patients, this treatment usually produces marked neurologic improvement, fading of Kayser-Fleischer rings, and gradual amelioration of hepatic dysfunction and psychic disturbances. Clinical experience to date suggests that life is prolonged with the above regimen. Noticeable improvement may not occur for one to three months. Occasionally, neurologic symptoms become worse during initiation of therapy with penicillamine tablets. Despite this, the drug should not be discontinued permanently. Although temporary interruption may result in clinical improvement of the neurological symptoms, it carries an increased risk of developing a sensitivity reaction upon resumption of therapy (See WARNINGS ). *For quantitative test for serum ceruloplasmin see: Morell, A.G.; Windsor, J.; Sternlieb, I; Scheinberg, I.H.: Measurement of the concentration of ceruloplasmin in serum by determination of its oxidase activity, in \\"Laboratory Diagnosis of Liver Disease,\\" F.W. Sunderman; F.W. Sunderman, Jr., (eds.), St. Louis, Warren H. Green, Inc., 1968, pp. 193 to 195. Treatment of asymptomatic patients has been carried out for over ten years. Symptoms and signs of the disease appear to be prevented indefinitely if daily treatment with penicillamine tablets can be continued. Cystinuria Cystinuria is characterized by excessive urinary excretion of the dibasic amino acids, arginine, lysine, ornithine, and cystine, and the mixed disulfide of cysteine and homocysteine. The metabolic defect that leads to cystinuria is inherited as an autosomal, recessive trait. Metabolism of the affected amino acids is influenced by at least two abnormal factors: (1) defective gastrointestinal absorption and (2) renal tubular dysfunction. Arginine, lysine, ornithine, and cysteine are soluble substances, readily excreted. There is no apparent pathology connected with their excretion in excessive quantities. Cystine, however, is so slightly soluble at the usual range of urinary pH that it is not excreted readily, and so crystallizes and forms stones in the urinary tract. Stone formation is the only known pathology in cystinuria. Normal daily output of cystine is 40 to 80 mg. In cystinuria, output is greatly increased and may exceed 1 g /day. At 500 to 600 mg/day, stone formation is almost certain. When it is more than 300 mg /day, treatment is indicated. Conventional treatment is directed at keeping urinary cystine diluted enough to prevent stone formation, keeping the urine alkaline enough to dissolve as much cystine as possible, and minimizing cystine production by a diet low in methionine (the major dietary precursor of cystine). Patients must drink enough fluid to keep urine specific gravity below 1.010, take enough alkali to keep urinary pH at 7.5 to 8, and maintain a diet low in methionine. This diet is not recommended in growing children and probably is contraindicated in pregnancy because of its low protein content (see PRECAUTIONS ). When these measures are inadequate to control recurrent stone formation, Penicillamine tablets may be used as additional therapy. When patients refuse to adhere to conventional treatment, Penicillamine tablets may be a useful substitute. It is capable of keeping cystine excretion to near normal values, thereby hindering stone formation and the serious consequences of pyelonephritis and impaired renal function that develop in some patients. Bartter and colleagues depict the process by which penicillamine interacts with cystine to form penicillamine-cysteine mixed disulfide as: CSSC= Cystine CS\'= deprotonated Cysteine PSSP=Penicillamine PS\'=deprotonated Penicillamine Sulfhydryl CSSP= Penicillamine-Cysteine Mixed Disulphide In this process, it is assumed that the deprotonated form of penicillamine, PS\', is the active factor in bringing about the disulfide interchange. Rheumatoid Arthritis Because penicillamine tablets, can cause severe adverse reactions, its use in rheumatoid arthritis should be restricted to patients who have severe, active disease and who have failed to respond to an adequate trial of conventional therapy. Even then, benefit-to-risk ratio should be carefully considered. Other measures, such as rest, physiotherapy, salicylates, and corticosteroids should be used, when indicated, in conjunction with penicillamine tablets (see PRECAUTIONS ). image 03"}', 'warnings_and_cautions': None, 'overdosage': None, 'active_flag': 'Y', 'generic_name': '{PENICILLAMINE}', 'route': '{ORAL}', 'product_type': '{"HUMAN PRESCRIPTION DRUG"}', 'stop_use': None, 'do_not_use': None, 'when_using': None, 'warnings': '{"WARNINGS The use of penicillamine has been associated with fatalities due to certain diseases, such as aplastic anemia, agranulocytosis, thrombocytopenia, Goodpasture\'s syndrome, and myasthenia gravis. Because of the potential for serious hematological and renal adverse reactions to occur at any time, routine urinalysis, white and differential blood cell count, hemoglobin determination, and direct platelet count must be done every two weeks for at least the first six months of penicillamine therapy and monthly thereafter. Patients should be instructed to report promptly the development of signs and symptoms of granulocytopenia and/or thrombocytopenia such as fever, sore throat, chills, bruising, or bleeding. The above laboratory studies should then be promptly repeated. Leukopenia and thrombocytopenia have been reported to occur in up to five percent of patients during penicillamine therapy. Leukopenia is of the granulocytic series and may or may not be associated with an increase in eosinophils. A confirmed reduction in WBC below 3500 per cubic mL mandates discontinuance of penicillamine therapy. Thrombocytopenia may be on an idiosyncratic basis with decreased or absent megakaryocytes in the marrow, when it is part of an aplastic anemia. In other cases the thrombocytopenia is presumably on an immune basis since the number of megakaryocytes in the marrow has been reported to be normal or sometimes increased. The development of a platelet count below 100,000 per cubic mL, even in the absence of clinical bleeding, requires at least temporary cessation of penicillamine therapy. A progressive fall in either platelet count or WBC in three successive determinations, even though values are still within the normal range, likewise requires at least temporary cessation. Proteinuria and/or hematuria may develop during therapy and may be warning signs of membranous glomerulopathy which can progress to a nephrotic syndrome. Close observation of these patients is essential. In some patients the proteinuria disappears with continued therapy; in others penicillamine must be discontinued. When a patient develops proteinuria or hematuria the physician must ascertain whether it is a sign of drug-induced glomerulopathy or is unrelated to penicillamine. Rheumatoid arthritis patients who develop moderate degrees of proteinuria may be continued cautiously on penicillamine therapy, provided that quantitative 24-hour urinary protein determinations are obtained at intervals of one to two weeks. Penicillamine dosage should not be increased under these circumstances. Proteinuria which exceeds 1 g/24 hours, or proteinuria which is progressively increasing requires either discontinuance of the drug or a reduction in the dosage. In some patients, proteinuria has been reported to clear following reduction in dosage. In rheumatoid arthritis patients, penicillamine should be discontinued if unexplained gross hematuria or persistent microscopic hematuria develops. In patients with Wilson\'s disease or cystinuria the risks of continued penicillamine therapy in patients manifesting potentially serious urinary abnormalities must be weighed against the expected therapeutic benefits. When penicillamine is used in cystinuria, an annual x-ray for renal stones is advised. Cystine stones form rapidly, sometimes in six months. Up to one year or more may be required for any urinary abnormalities to disappear after penicillamine has been discontinued. Because of rare reports of intrahepatic cholestasis and toxic hepatitis, liver function tests are recommended every six months for the duration of therapy. Goodpasture\'s syndrome has occurred rarely. The development of abnormal urinary findings associated with hemoptysis and pulmonary infiltrates on x-ray requires immediate cessation of penicillamine. Obliterative bronchiolitis has been reported rarely. The patient should be cautioned to report immediately pulmonary symptoms such as exertional dyspnea, unexplained cough, or wheezing. Pulmonary function studies should be considered at that time. Myasthenic syndrome sometimes progressing to myasthenia gravis has been reported. Ptosis and diplopia, with weakness of the extraocular muscles, are often early signs of myasthenia. In the majority of cases, symptoms of myasthenia have receded after withdrawal of penicillamine. Most of the various forms of pemphigus have occurred during treatment with penicillamine. Pemphigus vulgaris and pemphigus foliaceus are reported most frequently, usually as a late complication of therapy. The seborrhea-like characteristics of pemphigus foliaceus may obscure an early diagnosis. When pemphigus is suspected, penicillamine tablets should be discontinued. Treatment has consisted of high doses of corticosteroids alone or, in some cases, concomitantly with an immunosuppressant. Treatment may be required for only a few weeks or months, but may need to be continued for more than a year. Once instituted for Wilson\'s disease or cystinuria, treatment with penicillamine should, as a rule, be continued on a daily basis. Interruptions for even a few days have been followed by sensitivity reactions after reinstitution of therapy. Use In Pregnancy Penicillamine has been shown to be teratogenic in rats when given in doses 6 times higher than the highest dose recommended for human use (based on a standard weight of 50 kg). Skeletal defects, cleft palates, and fetal toxicity (resorptions) have been reported. There are no controlled studies on the use of penicillamine in pregnant women. Although normal outcomes have been reported, characteristic congenital cutis laxa and associated birth defects have been reported in infants born of mothers who received therapy with penicillamine during pregnancy. Penicillamine should be used in women of childbearing potential only when the expected benefits outweigh the possible hazards. Women on therapy with penicillamine who are of childbearing potential should be apprised of this risk, advised to report promptly any missed menstrual periods or other indications of possible pregnancy, and followed closely for early recognition of pregnancy. Wilson’s Disease Reported experience* shows that continued treatment with penicillamine throughout pregnancy protects the mother against relapse of the Wilson\'s disease, and that discontinuation of penicillamine has deleterious effects on the mother. If penicillamine is administered during pregnancy to patients with Wilson\'s disease, it is recommended that the daily dosage be limited to 1 g. If cesarean section is planned, the daily dosage should be limited to 250 mg during the last six weeks of pregnancy and post-operatively until wound healing is complete. Cystinuria If possible, penicillamine should not be given during pregnancy to women with cystinuria (see CONTRAINDICATIONS ). There are reports of women with cystinuria on therapy with penicillamine who gave birth to infants with generalized connective tissue defects who died following abdominal surgery. If stones continue to form in these patients, the benefits of therapy to the mother must be evaluated against the risk to the fetus. Rheumatoid Arthritis Penicillamine should not be administered to rheumatoid arthritis patients who are pregnant (see CONTRAINDICATIONS ) and should be discontinued promptly in patients in whom pregnancy is suspected or diagnosed. There is a report that a woman with rheumatoid arthritis treated with less than one gram a day of penicillamine during pregnancy gave birth (cesarean delivery) to an infant with growth retardation, flattened face with broad nasal bridge, low set ears, short neck with loose skin folds, and unusually lax body skin."}', 'precautions': '{"PRECAUTIONS Some patients may experience drug fever, a marked febrile response to penicillamine, usually in the second or third week following initiation of therapy. Drug fever may sometimes be accompanied by a macular cutaneous eruption. In the case of drug fever in patients with Wilson\'s disease or cystinuria, penicillamine should be temporarily discontinued until the reaction subsides. Then penicillamine should be reinstituted with a small dose that is gradually increased until the desired dosage is attained. Systemic steroid therapy may be necessary, and is usually helpful, in such patients in whom toxic reactions develop a second or third time. In the case of drug fever in rheumatoid arthritis patients, because other treatments are available, penicillamine should be discontinued and another therapeutic alternative tried, since experience indicates that the febrile reaction will recur in a very high percentage of patients upon readministration of penicillamine. The skin and mucous membranes should be observed for allergic reactions. Early and late rashes have occurred. Early rash occurs during the first few months of treatment and is more common. It is usually a generalized pruritic, erythematous, maculopapular, or morbilliform rash and resembles the allergic rash seen with other drugs. Early rash usually disappears within days after stopping penicillamine and seldom recurs when the drug is restarted at a lower dosage. Pruritus and early rash may often be controlled by the concomitant administration of antihistamines. Less commonly, a late rash may be seen, usually after six months or more of treatment, and requires discontinuation of penicillamine. It is usually on the trunk, is accompanied by intense pruritus, and is usually unresponsive to topical corticosteroid therapy. Late rash may take weeks to disappear after penicillamine is stopped and usually recurs if the drug is restarted. The appearance of a drug eruption accompanied by fever, arthralgia, lymphadenopathy, or other allergic manifestations usually requires discontinuation of penicillamine. Certain patients will develop a positive anti-nuclear antibody (ANA) test and some of these may show a lupus erythematosus-like syndrome similar to drug-induced lupus associated with other drugs. The lupus erythematosus-like syndrome is not associated with hypocomplementemia and may be present without nephropathy. The development of a positive ANA test does not mandate discontinuance of the drug; however, the physician should be alerted to the possibility that a lupus erythematosus-like syndrome may develop in the future. Some patients may develop oral ulcerations which in some cases have the appearance of aphthous stomatitis. The stomatitis usually recurs on rechallenge but often clears on a lower dosage. Although rare, cheilosis, glossitis, and gingivostomatitis have also been reported. These oral lesions are frequently dose-related and may preclude further increase in penicillamine dosage or require discontinuation of the drug. Hypogeusia (a blunting or diminution in taste perception) has occurred in some patients. This may last two to three months or more and may develop into a total loss of taste; however, it is usually self- limited, despite continued penicillamine treatment. Such taste impairment is rare in patients with Wilson\'s disease. * Scheinberg, I.H., Sternlieb, I.: N Engl J Med 293: 1300 to 1302, December 18, 1975. Penicillamine should not be used in patients who are receiving concurrently gold therapy, antimalarial or cytotoxic drugs, oxyphenbutazone, or phenylbutazone because these drugs are also associated with similar serious hematologic and renal adverse reactions. Patients who have had gold salt therapy discontinued due to a major toxic reaction may be at greater risk of serious adverse reactions with penicillamine, but not necessarily of the same type. Patients who are allergic to penicillin may theoretically have cross-sensitivity to penicillamine. The possibility of reactions from contamination of penicillamine by trace amounts of penicillin has been eliminated now that penicillamine is being produced synthetically rather than as a degradation product of penicillin. Because of their dietary restrictions, patients with Wilson\'s disease and cystinuria should be given 25 mg/day of pyridoxine during therapy, since penicillamine increases the requirement for this vitamin. Patients also may receive benefit from a multivitamin preparation, although there is no evidence that deficiency of any vitamin other than pyridoxine is associated with penicillamine. In Wilson\'s disease, multivitamin preparations must be copper-free. Rheumatoid arthritis patients whose nutrition is impaired should also be given a daily supplement of pyridoxine. Mineral supplements should not be given, since they may block the response to penicillamine. Iron deficiency may develop, especially in children and in menstruating women. In Wilson\'s disease, this may be a result of adding the effects of the low copper diet, which is probably also low in iron, and the penicillamine to the effects of blood loss or growth. In cystinuria, a low methionine diet may contribute to iron deficiency, since it is necessarily low in protein. If necessary, iron may be given in short courses, but a period of two hours should elapse between administration of penicillamine and iron, since orally administered iron has been shown to reduce the effects of penicillamine. Penicillamine causes an increase in the amount of soluble collagen. In the rat this results in inhibition of normal healing and also a decrease in tensile strength of intact skin. In man this may be the cause of increased skin friability at sites especially subject to pressure or trauma, such as shoulders, elbows, knees, toes, and buttocks. Extravasations of blood may occur and may appear as purpuric areas, with external bleeding if the skin is broken, or as vesicles containing dark blood. Neither type is progressive. There is no apparent association with bleeding elsewhere in the body and no associated coagulation defect has been found. Therapy with penicillamine may be continued in the presence of these lesions. They may not recur if dosage is reduced. Other reported effects probably due to the action of penicillamine on collagen are excessive wrinkling of the skin and development of small, white papules at venipuncture and surgical sites. The effects of penicillamine on collagen and elastin make it advisable to consider a reduction in dosage to 250 mg/day when surgery is contemplated. Reinstitution of full therapy should be delayed until wound healing is complete. Carcinogenesis Long-term animal carcinogenicity studies have not been done with penicillamine. There is a report that five of ten autoimmune disease-prone NZB hybrid mice developed lymphocytic leukemia after 6 months\' intraperitoneal treatment with a dose of 400 mg/kg penicillamine 5 days per week.
