GRISACTIN ULTRA vs MYCELEX-G
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Griseofulvin binds to tubulin and disrupts microtubule function, inhibiting fungal cell division and nucleic acid synthesis.
Clotrimazole, an imidazole antifungal, inhibits fungal cytochrome P450 14α-demethylase, disrupting ergosterol synthesis and increasing membrane permeability.
500 mg orally once daily or 250 mg orally twice daily; for severe infections, 500 mg twice daily or 250 mg three times daily. Maximum daily dose: 1 g. Administer with or after meals.
Clotrimazole 100 mg vaginal tablet inserted intravaginally once daily for 7 days or 200 mg once daily for 3 days; or 500 mg single dose. Also available as 1% vaginal cream, 1 applicatorful (5 g) intravaginally once daily for 7-14 days.

Terminal elimination half-life ranges from 6.5 to 9 hours (mean ~7.5 hours) in patients with normal hepatic function; prolonged in hepatic impairment.
Biphasic: initial half-life ~30 minutes, terminal half-life ~30 hours; clinical significance: supports once-daily dosing for topical/vaginal formulations.
Primarily hepatic metabolism; less than 1% excreted unchanged in urine; approximately 30-50% of a dose is eliminated in feces as metabolites, with minor biliary excretion.
Primarily hepatic metabolism; about 80-90% of dose excreted as metabolites in feces via biliary excretion, less than 1% unchanged in urine.
