# Oritavancin (Orbactiv / Kimyrsa) > Single-dose lipoglycopeptide for acute bacterial skin and skin structure infections. Source: https://peptides.cafe/peptide/oritavancin Category: Lipoglycopeptide · Antibiotic Tag: FDA-Approved · Antibiotic ## Mechanism Semisynthetic lipoglycopeptide derivative of chloroeremomycin that inhibits cell wall synthesis (transglycosylation, transpeptidation) and disrupts membrane integrity in Gram-positive bacteria including MRSA. ## Research areas - Acute bacterial skin and skin structure infections (ABSSSI) ## Common research protocols - Single IV dose: 1200 mg IV over 1–3 hours as a single dose. ## Study summaries - "SOLO trials" — NEJM (2014): Single dose non-inferior to 7–10 days of vancomycin in ABSSSI. ## Considerations - FDA-approved. - Artifactually elevates aPTT/PT for up to 48 hours; avoid unfractionated heparin for 48h. ## Disclaimer Educational content only.
