NYSTOP vs SPECTAZOLE
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Nystatin binds to ergosterol in fungal cell membranes, forming pores that disrupt membrane integrity, leading to leakage of intracellular ions and cell death.
Econazole nitrate, an imidazole antifungal, inhibits fungal cytochrome P450 14α-demethylase, disrupting ergosterol synthesis and increasing cell membrane permeability.
Apply a thin layer to affected area 2-3 times daily or as directed. Nystatin is not absorbed systemically; topical use only.
Apply a thin layer to affected area once daily for 4-4 weeks; duration depends on indication.

Not applicable for systemic pharmacokinetics due to minimal absorption; local half-life on mucosal surfaces is not defined. For intravenous administration (not approved), the terminal half-life is approximately 2-4 hours, but this route is not clinically used.
Terminal elimination half-life is approximately 24-30 hours in patients with normal renal function, allowing once-daily dosing.
Nystatin is not absorbed from the gastrointestinal tract or intact skin/mucous membranes; when administered topically or orally, it is excreted almost entirely in feces as unchanged drug (>99%). Less than 1% is excreted renally if ingested. No quantified biliary excretion reported.
Primarily renal: approximately 70% of an oral dose is excreted unchanged in urine; biliary/fecal excretion accounts for ~20%, with the remainder as metabolites.
