Each vial contains colistimethate sodium or pentasodium colistinmethanesulfonate (150 mg colistin base activity). Colistimethate sodium is a polypeptide antibiotic with an approximate molecular weight of 1750. The empirical formula is C 58 H 105 N 16 Na 5 O 28 S 5 and the structural formula is represented below: Dbu is 2,4-diaminobutanoic acid; R is 5-methylheptyl in colistin A and 5-methylhexyl in colistin B Chemical Structure
How to use
Important: Colistimethate for Injection, USP is supplied in vials containing colistimethate sodium equivalent to 150 mg colistin base activity per vial. Reconstitution for Intravenous or Intramuscular Administration The 150 mg vial should be reconstituted with 2 mL Sterile Water for Injection, USP. The reconstituted solution provides colistimethate sodium at a concentration equivalent to 75 mg/mL colistin base activity. During reconstitution swirl gently to avoid frothing. Parenteral drug products should be inspected visually for particulate matter and discoloration prior to administration, whenever solution and container permit. If these conditions are observed, the product should not be used. Dosage Adults and Pediatric Patients - Intravenous or Intramuscular Administration The dose of Colistimethate for Injection, USP should be 2.5 to 5 mg/kg per day of colistin base in 2 to 4 divided doses for patients with normal renal function, depending on the severity of the infection. In obese individuals, dosage should be based on ideal body weight. The daily dose and frequency should be reduced for the patients with renal impairment. Suggested modifications of dosage schedule for patients with renal impairment are presented in Table 1. Table 1 Suggested Modification of Dosage Schedules of Colistimethate for Injection, USP for Adults with Impaired Renal Function Degree of Renal…

Warnings
Important safety information
Maximum daily dose calculated from colistin base activity should not exceed 5 mg/kg/day with normal renal function. Transient neurological disturbances may occur. These include circumoral paresthesia or numbness, tingling or formication of the extremities, generalized pruritus, vertigo, dizziness, and slurring of speech. For these reasons, patients should be warned not to drive vehicles or use hazardous machinery while on therapy. Reduction of dosage may alleviate symptoms. Therapy need not be discontinued, but such patients should be observed with particular care. Nephrotoxicity can occur and is probably a dosedependent effect of colistimethate sodium. These manifestations of nephrotoxicity are reversible following discontinuation of the antibiotic. Overdosage can result in renal insufficiency, muscle weakness, and apnea (see OVERDOSAGE section). See PRECAUTIONS, Drug Interactions subsection for use concomitantly with other antibiotics and curariform drugs. Respiratory arrest has been reported following intramuscular administration of colistimethate sodium. Impaired renal function increases the possibility of apnea and neuromuscular blockade following administration of colistimethate sodium. Therefore, it is important to follow recommended dosing guidelines. See DOSAGE AND ADMINISTRATION section for use in renal impairment. Clostridium difficile associated diarrhea (CDAD) has…
Interactions
Drug Interactions Certain other antibiotics (aminoglycosides and polymyxin) have also been reported to interfere with the nerve transmission at the neuromuscular junction. Based on this reported activity, they should not be given concomitantly with Colistimethate for Injection, USP except with the greatest caution. Curariform muscle relaxants (e.g., tubocurarine) and other drugs, including ether, succinylcholine, gallamine, decamethonium and sodium citrate, potentiate the neuromuscular blocking effect and should be used with extreme caution in patients being treated with Colistimethate for Injection, USP. Sodium cephalothin may enhance the nephrotoxicity of Colistimethate for Injection, USP. The concomitant use of sodium cephalothin and Colistimethate for Injection, USP should be avoided.
