Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Binds to microtubule-associated proteins and disrupts fungal mitotic spindle formation, thereby inhibiting fungal cell division. It also interferes with fungal nucleic acid synthesis.
Vancomycin inhibits cell wall synthesis by binding to the D-alanyl-D-alanine terminus of peptidoglycan precursors, preventing cross-linking.
500 mg orally once daily (non-microsize formulation) or 250 mg twice daily; typical duration is 4-8 weeks for tinea capitis, 2-6 weeks for tinea corporis, 4-6 weeks for tinea pedis.
500-1000 mg orally every 12 hours or 250 mg every 6 hours.

Terminal half-life: 9–24 hours. Clinical context: Steady-state achieved in 2–5 days; prolonged in hepatic impairment.
Terminal elimination half-life: 8-12 hours in patients with normal renal function; prolonged to 20-40 hours in severe renal impairment (CrCl <30 mL/min), necessitating dose adjustment.
Renal (1% unchanged), fecal (33% as metabolites), biliary (minor). Extensive hepatic metabolism; <1% excreted unchanged in urine.
Renal (unchanged): 30-50% within 24 hours; Biliary/fecal: 15-25% as metabolites; remainder undergoes hepatic metabolism.
