Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Fosfomycin inhibits bacterial cell wall synthesis by inactivating the enzyme UDP-N-acetylglucosamine enolpyruvyl transferase (MurA), which catalyzes the first step of peptidoglycan biosynthesis.
Mychel is a topical antifungal agent that inhibits ergosterol synthesis by binding to fungal cytochrome P450 14α-demethylase, disrupting fungal cell membrane integrity.

Terminal elimination half-life is 5.7 hours (range 3-8 hours) in patients with normal renal function; approximately 50 hours in end-stage renal disease (CrCl <10 mL/min).
Terminal half-life: 8.5-12 hours (mean 10.2 h) in normal renal function; prolonged to 18-30 h in severe renal impairment (CrCl <30 mL/min)
Primarily excreted unchanged in urine via glomerular filtration (approximately 90% of absorbed dose within 24-48 hours); small amount (approximately 10%) excreted in feces via biliary elimination.
Renal: ~70% unchanged; fecal: ~15% as metabolites; biliary: ~10%
