Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Aminoglycoside antibiotic that binds to the 30S ribosomal subunit, inhibiting bacterial protein synthesis by causing misreading of mRNA and incorporation of incorrect amino acids into the growing peptide chain.
Oritavancin is a lipoglycopeptide antibiotic that inhibits bacterial cell wall synthesis by binding to the D-alanyl-D-alanine terminus of the peptidoglycan precursor, disrupting transglycosylation and transpeptidation. It also disrupts bacterial membrane integrity and causes depolarization, leading to cell death.
1-2 g orally every 6 hours for 7-14 days. Or 500 mg intramuscularly every 12 hours.
1200 mg IV once daily for 3 days

Terminal elimination half-life is 9–12 hours in patients with normal renal function; may extend to >20 hours in impaired renal function, necessitating dose adjustment.
Terminal elimination half-life is approximately 15.1 hours in healthy adults; in patients with renal impairment, half-life is prolonged (up to 28 hours in severe renal impairment).
Primarily renal excretion of unchanged drug via glomerular filtration; >90% of absorbed dose excreted unchanged in urine within 24 hours. Minor biliary excretion (<1%) with fecal elimination accounting for <1%.
Primarily renal excretion as unchanged drug (approximately 33% of administered dose) and via biliary/fecal elimination (~50% recovered in feces as parent drug and metabolites).
