Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Miconazole inhibits fungal cytochrome P450 14α-demethylase, 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.
Insert one miconazole nitrate 200 mg vaginal suppository intravaginally once daily at bedtime for 3 consecutive days. Apply intravaginal cream as needed for symptom relief.
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.

After intravenous administration, the terminal elimination half-life is approximately 20-24 hours; after topical or intravaginal administration, systemic absorption is minimal, with a terminal half-life of 8-12 hours.
Not well characterized due to minimal systemic absorption; estimated to be 2-3 hours in plasma if absorbed.
Miconazole is primarily eliminated via hepatic metabolism with biliary excretion of metabolites; <1% of unchanged drug is excreted renally. Fecal elimination accounts for approximately 20-30% of the dose.
Primarily fecal via biliary elimination; less than 5% renal excretion of absorbed dose.
