AMBISOME vs GRISEOFULVIN
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.
Binds to microtubular protein tubulin, disrupting mitotic spindle formation and inhibiting fungal cell mitosis. Also interferes with fungal nucleic acid synthesis and cell wall deposition.
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.
500 mg orally once daily or 250 mg orally twice daily; microsize formulation: 500-1000 mg orally once daily; ultramicrosize formulation: 330-375 mg orally once daily. Administer with fatty meal to enhance absorption.

Clinical Note
moderateGriseofulvin + Estrone sulfate
"The metabolism of Estrone sulfate can be increased when combined with Griseofulvin."
Clinical Note
moderateGriseofulvin + Tranilast
"The risk or severity of adverse effects can be increased when Griseofulvin is combined with Tranilast."
Clinical Note
moderateGriseofulvin + Tolfenamic acid
"The risk or severity of adverse effects can be increased when Griseofulvin is combined with Tolfenamic acid."
Clinical Note
moderateGriseofulvin + Nimesulide
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 9 to 24 hours; clinically, it allows once or twice daily dosing.
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 hepatic metabolism; less than 1% excreted unchanged in urine; metabolites excreted in urine (approximately 50%) and feces (approximately 36%) within 24 hours.
