LANABIOTIC vs ORBACTIV
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
LANABIOTIC is a lantibiotic that inhibits bacterial cell wall synthesis by binding to lipid II, a key precursor in peptidoglycan biosynthesis, thereby disrupting cell wall integrity and causing cell death.
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.
500 mg orally every 12 hours for 7-14 days.

Terminal elimination half-life is 6-8 hours in patients with normal renal function; extends to 20-40 hours in severe renal impairment (CrCl <30 mL/min).
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).
Renal excretion of unchanged drug accounts for 60-80% of elimination; biliary/fecal excretion accounts for 15-30%.
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).
