Colistin pharmacokinetics

Clinical Microbiology and Infection Volume 18, Issue 1, pages 30-39, 11 OCT 2011

Simulations of steady-state colistin methanesulphonate (CMS) (a) and colistin (b) plasma concentrations vs. time following administration of the same daily dose of CMS with various dosing regimens (9 MIU/24 h (red), 4.5 MIU/12 h (blue), and 3 MIU/8 h (green)), for a typical patient with creatinine clearance set at 60 mL/min, CMS non-renal clearance and colistin clearance equal to 50 mL/min, and CMS and colistin Vss set at 15 L.

Efficacy and safety of high-dose ampicillin/sulbactam vs. colistin as monotherapy for the

• In the kill-curve studies

azithromycin and rifampin were rapidly bactericidal

sulbactam was more slowly bactericidal.

Trovafloxacin and doxycycline were bacteriostatic

None of the antimicrobials tested were bactericidal against

all strains tested

• The synergy studies demonstrated that the combinations of

sulbactam with azithromycin, rifampin, doxycycline, or

trovafloxacin were generally additive or indifferent.
