Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Griseofulvin binds to and disrupts microtubule function by inhibiting spindle formation and mitosis in dermatophytes, leading to inhibition of fungal cell division.
Natamycin is a polyene antifungal that binds to ergosterol in fungal cell membranes, increasing permeability and causing cell death.
165 mg orally once daily.
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 9-24 hours; dependent on formulation and absorption rate. Steady-state achieved within 4-5 days.
Not well characterized due to minimal systemic absorption; estimated to be 2-3 hours in plasma if absorbed.
Primarily renal excretion of metabolites; <1% excreted unchanged. Biliary/fecal elimination accounts for ~30% of metabolites.
Primarily fecal via biliary elimination; less than 5% renal excretion of absorbed dose.
