NYSTOP vs TERCONAZOLE
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.
Terconazole is a triazole antifungal agent that inhibits fungal cytochrome P450 14α-demethylase, thereby blocking the conversion of lanosterol to ergosterol, an essential component of the fungal cell membrane. This disrupts membrane integrity and function.
Apply a thin layer to affected area 2-3 times daily or as directed. Nystatin is not absorbed systemically; topical use only.
Intravaginal cream (0.4%, 0.8%): one applicatorful (approximately 5 g) intravaginally once daily at bedtime for 7 days; vaginal suppository (80 mg): one suppository intravaginally once daily at bedtime for 3 days.

Clinical Note
moderateTerconazole + Tranilast
"The risk or severity of adverse effects can be increased when Terconazole is combined with Tranilast."
Clinical Note
moderateTerconazole + Tolfenamic acid
"The risk or severity of adverse effects can be increased when Terconazole is combined with Tolfenamic acid."
Clinical Note
moderateTerconazole + Nimesulide
"The risk or severity of adverse effects can be increased when Terconazole is combined with Nimesulide."
Clinical Note
moderateTerconazole + Risedronic acid
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 25-37 hours, allowing once-daily dosing for vaginal infections.
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 hepatic metabolism with biliary excretion; approximately 60-80% of the dose is excreted in feces as metabolites, and about 20% in urine mostly as inactive metabolites.
