Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Binds to tubulin, disrupting microtubule function and inhibiting fungal cell mitosis; deposited in keratin precursor cells, making keratin resistant to fungal invasion.
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.
250-375 mg orally once daily or 500-750 mg orally once daily for severe infections.
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.

9-24 hours (mean 15 hours); prolonged in liver disease.
Terminal elimination half-life is approximately 1.7 hours for the absorbed fraction, reflecting rapid renal clearance.
Renal (<1% unchanged); fecal (36% as metabolites); tissue deposition may persist for weeks.
Less than 1% of topically applied ciclopirox is absorbed; absorbed drug is conjugated and excreted renally as glucuronides, with minor fecal elimination.
