Activité biologique
Colistins are bactericidal to gram-negative bacteria by a detergent-like mechanism. This mechanism involves interaction with lipopolysaccharides and phospholipids of the outer membrane and electrostatic interference with the outer membrane by competitively displacing divalent cations (calcium and magnesium) from the negatively charged phosphate groups of membrane lipids[1]. Colistin (polymyxin E) owns favorable properties of rapid bacterial killing, a narrow spectrum of activity, and an associated slow development of resistance for the treatment of infections caused by multidrug-resistant gram-negative bacteria. There are two forms of colistin available commercially: colistin (sulfate) mainly for topical use and colistin methanesulfonate (sodium) for parenteral use[2].

Protocole
Rats: Colistin methanesulfonate (sodium) and colistin (sulfate) dosing solutions are freshly prepared in sterile 0.9% sodium chloride. For the i.v. studies, colistin methanesulfonate (CMS) or sulfate solutions are administered by a bolus injection via the jugular vein cannula. Intratracheal (i.t.) instillation is utilized as the technique for pulmonary administration. Animals are administered i.v. CMS at doses of 14 mg/kg of body weight, 28 mg/kg or 56 mg/kg. In an independent study, rats are administered i.v. colistin at doses of 0.21 mg/kg, 0.41 mg/kg, or 0.62 mg/kg[3].
