MICONAZOLE 7 vs NATACYN
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Imidazole antifungal agent that inhibits fungal cytochrome P450 14α-demethylase, thereby blocking ergosterol synthesis and disrupting fungal cell membrane integrity.
Natamycin is a polyene antifungal that binds to ergosterol in fungal cell membranes, increasing permeability and causing cell death.
Apply 200 mg (one full applicator) intravaginally once daily at bedtime for 7 days.
One drop of 5% ophthalmic suspension into the conjunctival sac every 1-2 hours for 48 hours, then taper to one drop 4-6 times daily.

Terminal half-life 24-30 hours; prolonged in hepatic impairment
Not well characterized due to minimal systemic absorption; estimated to be 2-3 hours in plasma if absorbed.
Primarily fecal (~50%) and renal (~<1% unchanged)
Primarily fecal via biliary elimination; less than 5% renal excretion of absorbed dose.
