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.
Intravaginal administration of one applicator (200 mg miconazole nitrate) at bedtime for 3 consecutive 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 20-30 hours for miconazole after systemic absorption, reflecting slow elimination from deep tissue compartments.
Not well characterized due to minimal systemic absorption; estimated to be 2-3 hours in plasma if absorbed.
Approximately 50% of absorbed dose excreted in feces via biliary elimination; <1% excreted unchanged in urine. Unabsorbed drug from vaginal administration is eliminated in vaginal discharge.
Primarily fecal via biliary elimination; less than 5% renal excretion of absorbed dose.
