MONISTAT 7 vs NATACYN
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Miconazole, an imidazole antifungal, inhibits fungal cytochrome P450 14α-demethylase, reducing 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.
Intravaginal administration of 100 mg miconazole nitrate suppository 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 elimination half-life is approximately 24-30 hours following intravaginal administration; clinical significance: supports once-daily dosing.
Not well characterized due to minimal systemic absorption; estimated to be 2-3 hours in plasma if absorbed.
Primarily via feces (approximately 87-93% of dose) as unchanged drug and metabolites; renal excretion negligible (<1%).
Primarily fecal via biliary elimination; less than 5% renal excretion of absorbed dose.
