FUNGIZONE vs GRIS-PEG
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.
Griseofulvin binds to and disrupts microtubule function by interfering with the polymerization of tubulin, thereby inhibiting fungal cell mitosis and nucleic acid synthesis.
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.
For tinea capitis and other dermatophyte infections: 500 mg oral daily as a single dose or in divided doses. For more severe infections, up to 1 g daily in divided doses.

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.
Terminal elimination half-life 14-24 hours. With continuous therapy, time to steady-state is ~3-5 days.
Primarily fecal (40-50%) via biliary elimination without metabolism; renal excretion of unchanged drug is minimal (<5% in 24 hours).
Primarily renal (as glucuronide conjugates): ~80%; fecal/biliary: ~10-15%; unchanged drug <1%.
