FULVICIN P/G 330 vs NOXAFIL
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Fulvicin P/G 330 contains griseofulvin, which inhibits fungal cell mitosis by disrupting the microtubule function, binding to tubulin and preventing assembly of spindle fibers during metaphase.
Inhibits fungal cytochrome P450-dependent 14α-demethylase, blocking ergosterol synthesis and disrupting fungal cell membrane integrity.
330 mg orally once daily 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.

Terminal half-life approximately 9-22 hours in adults, with a mean of ~13 hours. Clinical context: steady-state achieved in 2-3 days; may guide dosing interval.
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; <1% excreted unchanged in urine. Biliary/fecal excretion of metabolites: ~36% in feces, ~13% in urine.
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).
