Clinical Drug Information
Indications & Usage
1 INDICATIONS AND USAGE Azithromycin for injection, USP is a macrolide antibacterial drug indicated for the treatment of patients with infections caused by susceptible strains of the designated microorganisms in the conditions listed below. Azithromycin is a macrolide antibacterial drug indicated for mild to moderate infections caused by designated, susceptible bacteria: Community-acquired pneumonia in adults ( 1.1 ) Pelvic inflammatory disease ( 1.2 ) To reduce the development of drug-resistant bacteria and maintain the effectiveness of azithromycin and other antibacterial drugs, azithromycin should be used only to treat or prevent infections that are proven or strongly suspected to be caused by susceptible bacteria. ( 1.3 ) 1.1 Community-Acquired Pneumonia due to Chlamydophila pneumoniae , Haemophilus influenzae , Legionella pneumophila , Moraxella catarrhalis , Mycoplasma pneumoniae , Staphylococcus aureus , or Streptococcus pneumoniae in patients who require initial intravenous therapy. 1.2 Pelvic Inflammatory Disease due to Chlamydia trachomatis , Neisseria gonorrhoeae , or Mycoplasma hominis in patients who require initial intravenous therapy. If anaerobic microorganisms are suspected of contributing to the infection, an antimicrobial agent with anaerobic activity should be administered in combination with azithromycin. Azithromycin for injection, USP should be followed by azithromycin by the oral route as required. [see Dosage and Administration ( 2 )] 1.3 Usage To reduce the development of drug-resistant bacteria and maintain the effectiveness of azithromycin and other antibacterial drugs, azithromycin should be used only to treat infections that are proven or strongly suspected to be caused by susceptible bacteria. When culture and susceptibility information are available, they 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.
Dosage & Administration
2 DOSAGE AND ADMINISTRATION [see Indications and Usage ( 1 ) and Clinical Pharmacology ( 12.3 )] Community-acquired pneumonia: 500 mg as a single daily dose by the intravenous route for at least two days. ( 2.1 ) Pelvic inflammatory disease in adults: 500 mg as a single daily dose by the intravenous route for one or two days. ( 2.2 ) 2.1 Community-Acquired Pneumonia The recommended dose of azithromycin for injection for the treatment of adult patients with community-acquired pneumonia due to the indicated organisms is 500 mg as a single daily dose by the intravenous route for at least two days. Intravenous therapy should be followed by azithromycin by the oral route at a single, daily dose of 500 mg, administered as two 250 mg tablets to complete a 7- to 10-day course of therapy. The timing of the switch to oral therapy should be done at the discretion of the physician and in accordance with clinical response. 2.2 Pelvic Inflammatory Disease The recommended dose of azithromycin for injection for the treatment of adult patients with pelvic inflammatory disease due to the indicated organisms is 500 mg as a single daily dose by the intravenous route for one or two days. Intravenous therapy should be followed by azithromycin by the oral route at a single, daily dose of 250 mg to complete a 7-day course of therapy. The timing of the switch to oral therapy should be done at the discretion of the physician and in accordance with clinical response. 2.3 Preparation of the Solution for Intravenous Administration The infusate concentration and rate of infusion for azithromycin for injection should be either 1 mg/mL over 3 hr or 2 mg/mL over 1 hr. Azithromycin for injection should not be given as a bolus or as an intramuscular injection. Reconstitution Prepare the initial solution of azithromycin for injection by adding 4.8 mL of Sterile Water for Injection to the 500 mg vial, and shaking the vial until all of the drug is dissolved. Since azithromycin for injection is supplied under vacuum, it is recommended that a standard 5 mL (non-automated) syringe be used to ensure that the exact amount of 4.8 mL of Sterile Water is dispensed. Each mL of reconstituted solution contains 100 mg azithromycin. Reconstituted solution is stable for 24 hr when stored below 30°C (86°F). Parenteral drug products should be inspected visually for particulate matter prior to administration. If particulate matter is evident in reconstituted fluids, the drug solution should be discarded. Dilute this solution further prior to administration as instructed below. Dilution To provide azithromycin over a concentration range of 1 to 2 mg/mL, transfer 5 mL of the 100 mg/mL azithromycin solution into the appropriate amount of any of the diluents listed below: Normal Saline (0.9% sodium chloride) 1/2 Normal Saline (0.45% sodium chloride) 5% Dextrose in Water Lactated Ringer’s Solution 5% Dextrose in 1/2 Normal Saline (0.45% sodium chloride) with 20 mEq KCl 5% Dextrose in Lactated Ringer’s Solution 5% Dextrose in 1/3 Normal Saline (0.3% sodium chloride) 5% Dextrose in 1/2 Normal Saline (0.45% sodium chloride) Normosol ®* -M in 5% Dextrose Normosol ®* -R in 5% Dextrose Final Infusion Solution Concentration (mg/mL ) Amount of Diluent (mL) 1 mg/mL 500 mL 2 mg/mL 250 mL Other intravenous substances, additives, or medications should not be added to azithromycin for injection, or infused simultaneously through the same intravenous line. Storage When diluted according to the instructions (1 mg/mL to 2 mg/mL), azithromycin for injection is stable for 24 hr at or below room temperature 30°C (86°F), or for 7 days if stored under refrigeration 5°C (41°F).
Adverse Reactions
6 ADVERSE REACTIONS Most common adverse reactions are nausea (4%), diarrhea (4%), abdominal pain (3%), or vomiting (1%). (6) To report SUSPECTED ADVERSE REACTIONS, contact Sun Pharmaceutical Industries, Inc. at 1-800-818-4555 or FDA at 1-800-FDA-1088 or www.fda.gov/medwatch. 6.1 Clinical Trials Experience Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice. In clinical trials of intravenous azithromycin for community-acquired pneumonia, in which 2 to 5 IV doses were given, the reported adverse reactions were mild to moderate in severity and were reversible upon discontinuation of the drug. The majority of patients in these trials had one or more co-morbid diseases and were receiving concomitant medications. Approximately 1.2% of the patients discontinued intravenous azithromycin therapy, and a total of 2.4% discontinued azithromycin therapy by either the intravenous or oral route because of clinical or laboratory side effects. In clinical trials conducted in patients with pelvic inflammatory disease, in which 1 to 2 IV doses were given, 2% of women who received monotherapy with azithromycin and 4% who received azithromycin plus metronidazole discontinued therapy due to clinical side effects. Clinical adverse reactions leading to discontinuations from these studies were gastrointestinal (abdominal pain, nausea, vomiting, diarrhea), and rashes; laboratory side effects leading to discontinuation were increases in transaminase levels and/or alkaline phosphatase levels. Overall, the most common adverse reactions associated with treatment in adult patients who received IV/Oral azithromycin in studies of community-acquired pneumonia were related to the gastrointestinal system with diarrhea/loose stools (4.3%), nausea (3.9%), abdominal pain (2.7%), and vomiting (1.4%) being the most frequently reported. Approximately 12% of patients experienced a side effect related to the intravenous infusion; most common were pain at the injection site (6.5%) and local inflammation (3.1%). The most common adverse reactions associated with treatment in adult women who received IV/Oral azithromycin in trials of pelvic inflammatory disease were related to the gastrointestinal system. Diarrhea (8.5%) and nausea (6.6%) were most commonly reported, followed by vaginitis (2.8%), abdominal pain (1.9%), anorexia (1.9%), rash and pruritus (1.9%). When azithromycin was coadministered with metronidazole in these trials, a higher proportion of women experienced adverse reactions of nausea (10.3%), abdominal pain (3.7%), vomiting (2.8%), infusion site reaction, stomatitis, dizziness, or dyspnea (all at 1.9%). Adverse reactions that occurred with a frequency of 1% or less included the following: Gastrointestinal: Dyspepsia, flatulence, mucositis, oral moniliasis, and gastritis. Nervous system: Headache, somnolence. Allergic: Bronchospasm. Special senses: Taste perversion. 6.2 Postmarketing Experience The following adverse reactions have been identified during post-approval use of azithromycin. 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. Adverse reactions reported with azithromycin during the postmarketing period in adult and/or pediatric patients for which a causal relationship may not be established include: Allergic: Arthralgia, edema, urticaria and angioedema. Cardiovascular: Arrhythmias including ventricular tachycardia and hypotension. There have been reports of QT prolongation and torsades de pointes . Gastrointestinal: Anorexia, constipation, dyspepsia, flatulence, vomiting/diarrhea, pseudomembranous colitis, pancreatitis, oral candidiasis, pyloric stenosis, and reports of tongue discoloration. General: Asthenia, paresthesia, fatigue, malaise and anaphylaxis (including fatalities). Genitourinary: Interstitial nephritis and acute renal failure and vaginitis. Hematopoietic: Thrombocytopenia. Liver/biliary: Abnormal liver function, hepatitis, cholestatic jaundice, hepatic necrosis, and hepatic failure. [ see Warnings and Precautions ( 5.2 )] Nervous system: Convulsions, dizziness/vertigo, headache, somnolence, hyperactivity, nervousness, agitation and syncope. Psychiatric: Aggressive reaction and anxiety. Skin/appendages: Pruritus, serious skin reactions including, erythema multiforme, AGEP, Stevens-Johnson syndrome, toxic epidermal necrolysis, and DRESS. Special senses: Hearing disturbances including hearing loss, deafness and/or tinnitus and reports of taste/smell perversion and/or loss. 6.3 Laboratory Abnormalities Significant abnormalities (irrespective of drug relationship) occurring during the clinical trials were reported as follows: elevated ALT (SGPT), AST (SGOT), creatinine (4 to 6%) elevated LDH, bilirubin (1 to 3%) leukopenia, neutropenia, decreased platelet count, and elevated serum alkaline phosphatase (less than 1%) When follow-up was provided, changes in laboratory tests appeared to be reversible. In multiple-dose clinical trials involving more than 750 patients treated with azithromycin(IV/Oral), less than 2% of patients discontinued azithromycin therapy because of treatment-related liver enzyme abnormalities.
Information for Patients
17 PATIENT COUNSELING INFORMATION Patients should be informed of the following serious and potentially serious adverse reactions that have been associated with azithromycin. Diarrhea: Inform patients that diarrhea is a common problem caused by antibacterial drugs which usually ends when the antibacterial is discontinued. Sometimes after starting treatment with antibacterials, patients can develop watery and bloody stools (with or without stomach cramps and fever) even as late as two or more months after having taken the last dose of the antibacterial. If this occurs, patients should notify their physician as soon as possible. * All trademarks are the property of their respective owners. Distributed by: Sun Pharmaceutical Industries, Inc .
