Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Econazole nitrate, an imidazole antifungal, inhibits fungal cytochrome P450 14α-demethylase (CYP51), blocking ergosterol synthesis, disrupting fungal cell membrane integrity and function.
Posaconazole inhibits fungal CYP450-dependent 14α-demethylase, blocking ergosterol synthesis and disrupting fungal cell membrane integrity.
Topical: Apply a thin layer to affected area twice daily (morning and evening). Vaginal: One applicatorful (150 mg) intravaginally at bedtime for 3 days. Rectal candidiasis: One 150 mg suppository rectally at bedtime for 3 days.
300 mg (one 300-mg vial) intravenously twice on day 1, then 300 mg intravenously once daily starting on day 2. Alternatively, oral suspension: 200 mg (10 mL) three times daily. For prophylaxis, IV: 300 mg twice on day 1, then 300 mg once daily; oral: 200 mg three times daily.

Terminal elimination half-life approximately 8-10 hours; clinical relevance: supports twice-daily topical dosing for sustained antifungal effect.
The terminal elimination half-life is approximately 27 hours (range 20-66 hours) in healthy subjects, allowing for once-daily dosing after steady state.
Primarily hepatic metabolism; <1% unchanged in urine; 30-45% in feces as metabolites; minimal biliary excretion.
Posaconazole is primarily excreted in the feces (77%) as unchanged drug, with renal excretion accounting for 14% of the dose (primarily as glucuronide conjugates). Less than 0.2% is excreted unchanged in urine.
