Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Miconazole inhibits fungal cytochrome P450 14α-demethylase, thereby blocking the conversion of lanosterol to ergosterol, a key component of the fungal cell membrane. This disrupts membrane integrity and leads to fungal cell death. Miconazole also has direct anti-inflammatory and antibacterial properties.
Natamycin is a polyene antifungal that binds to ergosterol in fungal cell membranes, increasing permeability and causing cell death.
Miconazole nitrate 1200 mg vaginal suppository inserted intravaginally once at bedtime; plus external miconazole nitrate 2% cream applied to affected area twice daily for up to 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: 24-30 hours (range 20-50 hours). Clinical context: Once-daily dosing may be considered for some indications, but prolonged half-life supports weekly or twice-weekly regimens for systemic infections.
Not well characterized due to minimal systemic absorption; estimated to be 2-3 hours in plasma if absorbed.
Fecal: Approximately 90% of absorbed dose; Renal: <2% as unchanged drug; Biliary: Minor, less than 10%.
Primarily fecal via biliary elimination; less than 5% renal excretion of absorbed dose.
