Colistin versus polymyxin B: A pragmatic assessment of renal and neurological adverse effects and effectiveness in multidrug-resistant Gram-negative bacterial infections.

Objectives: Our study aimed to evaluate the real-world data on renal and neurological adverse effects and effectiveness of colistimethate sodium (CMS) and polymyxin B (PMB).

Materials And Methods: An observational prospective study was performed on inpatients receiving CMS and PMB for multidrug-resistant Gram-negative bacterial infections. CMS dose was titrated to renal function, and serum creatinine was assessed daily.
