Background:
Colistin methanesulfonate is an inactive prodrug of colistin (also known as polymyxin E), which is an antibiotic with effect against most Gram-negative bacteria, but also causes nephro- and neurotoxicity [1]. Colistin is produced by certain strains of the bacteria Paenibacillus polymyxa, and belongs to the class of polypeptide antibiotics known as polymyxins.
In Vitro: Studying the time-kill kinetics of Colistin methanesulfonate against a type culture of pseudomonas aeruginosa found that 8.0 or 32 mg/l Colistin methanesulfonate began killing at approximately 90 or 30 min, and the mean AUC0-240 values were 186.3±6.0 and 90.4±4.1, respectively [2]. Besides, by investigation among mucoid and nonmucoid strains of Pseudomonas aeruginosa isolated from patients with cystic fibrosis, Colistin methanesulfonate was found to require a concentration of 16 times the MIC to achieve complete killing within 24 h [3].
In Vivo: no data available.
Clinical trial: no data available.
