Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Miconazole nitrate inhibits fungal lanosterol 14α-demethylase (CYP51), disrupting ergosterol synthesis and causing fungal cell membrane damage.
Natamycin is a polyene antifungal that binds to ergosterol in fungal cell membranes, increasing permeability and causing cell death.
Intravaginally, one suppository (100 mg miconazole nitrate) once daily at bedtime for 7 days or one suppository (200 mg) once daily for 3 days, combined with topical application of miconazole nitrate cream (2%) to the vulvar area twice daily 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 20-25 hours, but can be prolonged to 30-40 hours in patients with hepatic impairment.
Not well characterized due to minimal systemic absorption; estimated to be 2-3 hours in plasma if absorbed.
Primarily fecal (biliary) as unchanged drug and metabolites (~50-60%); renal excretion accounts for <20% of the dose, mostly as inactive metabolites.
Primarily fecal via biliary elimination; less than 5% renal excretion of absorbed dose.
