Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Miconazole inhibits fungal lanosterol 14α-demethylase, a cytochrome P450 enzyme, 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.
Topical: Apply once daily to affected areas for 2-4 weeks. Vaginal: One 200 mg suppository at bedtime for 3 days, or one 100 mg suppository at bedtime for 7 days, or one 1200 mg suppository as a single dose.
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, supporting twice-daily or once-daily dosing for dermatologic infections.
Not well characterized due to minimal systemic absorption; estimated to be 2-3 hours in plasma if absorbed.
Primarily fecal (biliary) elimination as unchanged drug and metabolites; <1% renal excretion of unchanged drug.
Primarily fecal via biliary elimination; less than 5% renal excretion of absorbed dose.
