Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Amphotericin B binds to ergosterol in fungal cell membranes, forming pores that disrupt membrane integrity, leading to leakage of intracellular contents and fungal cell death.
Griseofulvin binds to and disrupts microtubule function by inhibiting spindle formation and mitosis in dermatophytes, leading to inhibition of fungal cell division.
3-5 mg/kg/day intravenously for systemic fungal infections; for visceral leishmaniasis: 3 mg/kg/day IV on days 1-5, 14, and 21.
165 mg orally once daily.

Terminal elimination half-life: approximately 7–10 hours (initial phase), with a prolonged terminal half-life of 100–153 hours due to slow redistribution from tissues; clinically, this supports once-daily dosing after initial accumulation.
Terminal elimination half-life is approximately 9-24 hours; dependent on formulation and absorption rate. Steady-state achieved within 4-5 days.
Renal: negligible (<1% unchanged); Biliary/fecal: primary route, approximately 90% of dose recovered in feces as parent drug and metabolites; Urinary: minimal (less than 1% as unchanged drug).
Primarily renal excretion of metabolites; <1% excreted unchanged. Biliary/fecal elimination accounts for ~30% of metabolites.
