Colistin (Polymyxin E) vs Oritavancin (Orbactiv / Kimyrsa)
An educational, source-based comparison of Colistin (Polymyxin E) and Oritavancin (Orbactiv / Kimyrsa) — how each peptide works, what it's researched for, and what to know before going deeper.
Last-resort lipopeptide antibiotic for multidrug-resistant Gram-negatives.
Cationic cyclic lipopeptide that disrupts the outer membrane of Gram-negative bacteria by binding lipid A of LPS, causing membrane permeability and cell death.
- Carbapenem-resistant Acinetobacter, Klebsiella, Pseudomonas
- • FDA-approved.
- • Nephrotoxicity and neurotoxicity dose-limiting.
Single-dose lipoglycopeptide for acute bacterial skin and skin structure infections.
Semisynthetic lipoglycopeptide derivative of chloroeremomycin that inhibits cell wall synthesis (transglycosylation, transpeptidation) and disrupts membrane integrity in Gram-positive bacteria including MRSA.
- Acute bacterial skin and skin structure infections (ABSSSI)
- • FDA-approved.
- • Artifactually elevates aPTT/PT for up to 48 hours; avoid unfractionated heparin for 48h.
