FULVICIN P/G 330 vs LOPROX
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.
Ciclopirox is a hydroxypyridone antifungal agent that inhibits metal-dependent enzymes, including cytochromes, by chelating polyvalent cations (Fe3+, Al3+). It disrupts fungal cell membrane integrity and mitochondrial electron transport, leading to fungicidal activity. It also has anti-inflammatory properties by inhibiting prostaglandin and leukotriene synthesis.
330 mg orally once daily with fatty meal to enhance absorption.
Ciclopirox 1% cream or lotion: apply to affected area twice daily. Nail lacquer (8%): apply to affected nails daily. Shampoo (1%): apply 5-10 mL to wet scalp, lather, leave for 3 minutes, rinse; use twice weekly.

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 1.7 hours for the absorbed fraction, reflecting rapid renal clearance.
Primarily hepatic metabolism; <1% excreted unchanged in urine. Biliary/fecal excretion of metabolites: ~36% in feces, ~13% in urine.
Less than 1% of topically applied ciclopirox is absorbed; absorbed drug is conjugated and excreted renally as glucuronides, with minor fecal elimination.
