DIFICID vs LANABIOTIC
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Fidaxomicin is a macrocyclic antibiotic that inhibits bacterial RNA polymerase, leading to RNA synthesis inhibition and cell death. It is bactericidal against Clostridioides difficile and has minimal systemic absorption.
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.
200 mg (tablet) orally twice daily for 10 days.
500 mg orally every 12 hours for 7-14 days.

11.7 hours (terminal half-life in healthy subjects); supports twice-daily dosing.
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).
Fecal (primarily as unchanged drug, ~44% of dose); renal (~1.6% unchanged, <1% as metabolites); biliary (minor).
Renal excretion of unchanged drug accounts for 60-80% of elimination; biliary/fecal excretion accounts for 15-30%.
