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.
Inhibits fungal cytochrome P450-dependent 14α-demethylase, blocking ergosterol synthesis and disrupting fungal cell membrane integrity.
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.
Posaconazole oral suspension: 200 mg (5 mL) three times daily with food. Oral delayed-release tablets: 300 mg twice daily on day 1, then 300 mg once daily thereafter with food. IV: 300 mg twice daily on day 1, then 300 mg once daily.

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

Terminal elimination half-life is 9 to 24 hours; clinically, it allows once or twice daily dosing.
Terminal elimination half-life is approximately 25-30 hours (range 20-66 hours) in healthy subjects; in patients with hepatic impairment or critical illness, half-life may be prolonged up to 40-50 hours; supports once-daily dosing in most patients.
Primarily hepatic metabolism; less than 1% excreted unchanged in urine; metabolites excreted in urine (approximately 50%) and feces (approximately 36%) within 24 hours.
Primarily hepatic metabolism (glucuronidation) with extensive enterohepatic recirculation; renal excretion accounts for <1% as unchanged drug; approximately 71% of a radiolabeled dose is eliminated in feces (as parent drug and metabolites) and 13% in urine (as metabolites).
