GRISEOFULVIN vs LAMISIL
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
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.
Allylamine antifungal that inhibits squalene epoxidase, an enzyme in the ergosterol biosynthesis pathway, leading to accumulation of squalene and disruption of fungal cell membrane function.
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.
250 mg orally once daily for 2-6 weeks for dermatophyte infections; 250 mg orally once daily for 12 weeks for onychomycosis.

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 is 9 to 24 hours; clinically, it allows once or twice daily dosing.
Terminal elimination half-life is approximately 17-24 hours in healthy adults. However, it can prolong to about 36-40 hours in patients with renal or hepatic impairment. The prolonged half-life allows for once-daily dosing. Due to extensive tissue distribution, the functional half-life (terminal phase from tissues) may be longer.
Primarily hepatic metabolism; less than 1% excreted unchanged in urine; metabolites excreted in urine (approximately 50%) and feces (approximately 36%) within 24 hours.
Approximately 70% of the administered dose is excreted in the urine as metabolites, with less than 5% as unchanged drug. About 20% is eliminated via feces. Terbinafine undergoes extensive hepatic metabolism; renal elimination of metabolites is the primary route.
