Colistin pharmacokinetics (PK) was investigated in young healthy volunteers after a 1-h infusion of 80 mg (1 million international units (MIU)) of the prodrug colistin methanesulfonate (CMS). Concentration levels of CMS and colistin were determined in plasma and urine using

Antimicrobial agents and chemotherapy, 55(7), 3284-3294 (2011-05-11)
With increasing clinical emergence of multidrug-resistant Gram-negative pathogens and the paucity of new agents to combat these infections, colistin (administered as its inactive prodrug colistin methanesulfonate [CMS]) has reemerged as a treatment option, especially for critically ill patients. There has

Journal of cystic fibrosis : official journal of the European Cystic Fibrosis Society, 11(5), 419-426 (2012-06-22)
Various inhaled antibiotics are currently used for treating chronic Pseudomonas aeruginosa lung infection in cystic fibrosis (CF) patients, however their relative efficacies are unclear. We compared the efficacy of the inhaled antibiotics tobramycin (TIP, TIS-T, TIS-B), colistimethate sodium (colistin) and

The purpose of this study was to describe inhaled colistin pharmacokinetics in patients with ventilator-associated tracheobronchitis (VAT) due to polymyxin-only susceptible Gram-negative bacteria (GNB). Inhaled colistimethate sodium (CMS) was administered at a dose of 80 mg every 8 h for

Multidrug-resistant (MDR) gram-negative bacteria-related nosocomial infections and ventilator-associated pneumonia (VAP) presents an emerging challenge to clinicians. Older antimicrobial agents such as colistin have become life-saving drugs because of the susceptibility of these pathogens. We report our experience with aerosolized colistin
