CICLOPIROX vs EXTINA
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Ciclopirox is a hydroxypyridone antifungal agent that chelates polyvalent metal cations (e.g., Fe3+, Al3+) inhibiting metal-dependent enzymes, thereby disrupting fungal cellular metabolic processes, including mitochondrial electron transport and energy production.
Antifungal agent that inhibits the enzyme 14α-demethylase, blocking the conversion of lanosterol to ergosterol, an essential component of fungal cell membranes.
Ciclopirox 8% nail lacquer: Apply to affected nails once daily for up to 48 weeks. Ciclopirox 1% cream or lotion: Apply to affected skin twice daily for 2-4 weeks. Ciclopirox 1% shampoo: Apply to wet hair, lather, leave for 3 minutes, rinse; use twice weekly for 4 weeks (for seborrheic dermatitis).
2.5% to 3.5% solution applied topically twice daily for 4 weeks.

Terminal elimination half-life: 1.7-3.0 hours in healthy individuals; prolonged in hepatic impairment
Terminal elimination half-life is approximately 24-32 hours in adults, allowing once-daily dosing. Half-life may be prolonged in patients with renal impairment.
Renal: approximately 70-80% of the absorbed dose as unchanged drug and glucuronide conjugates; biliary/fecal: ~20-30%
Primarily renal excretion of unchanged drug (approximately 80-90% of the absorbed dose), with minor hepatic metabolism and fecal elimination (<10%).
