FUNGIZONE vs NATACYN
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Binds to ergosterol in fungal cell membranes, forming pores that increase permeability, leading to leakage of intracellular contents and cell death.
Natamycin is a polyene antifungal that binds to ergosterol in fungal cell membranes, increasing permeability and causing cell death.
IV: 0.25-1 mg/kg/day as a single infusion; for aspergillosis, up to 1.5 mg/kg/day; maximum daily dose 1.5 mg/kg.
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 15 days (range 10-20 days) after a single dose; with prolonged therapy, a prolonged terminal half-life of up to 15 days reflects slow redistribution from tissue depots.
Not well characterized due to minimal systemic absorption; estimated to be 2-3 hours in plasma if absorbed.
Primarily fecal (40-50%) via biliary elimination without metabolism; renal excretion of unchanged drug is minimal (<5% in 24 hours).
Primarily fecal via biliary elimination; less than 5% renal excretion of absorbed dose.
