ANCOBON vs GRISEOFULVIN
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Flucytosine is converted intracellularly to 5-fluorouracil, which inhibits fungal RNA and DNA synthesis by incorporating into RNA and inhibiting thymidylate synthase.
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.
50-150 mg/kg/day orally divided every 6 hours; intravenous dosing: 50-150 mg/kg/day divided every 12 hours.
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 2.5-6 hours (normal renal function). Prolonged to 30-250 hours in renal impairment (CrCl < 20 mL/min). Half-life correlates with creatinine clearance.
Terminal elimination half-life is 9 to 24 hours; clinically, it allows once or twice daily dosing.
Primarily renal excretion of unchanged drug (75-90% within 24 hours). Less than 1% eliminated as 5-fluorouracil metabolite. Biliary/fecal excretion negligible.
Primarily hepatic metabolism; less than 1% excreted unchanged in urine; metabolites excreted in urine (approximately 50%) and feces (approximately 36%) within 24 hours.
