NYSTAFORM 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 and cause leakage of intracellular contents, leading to fungal 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.
1 tablet (nystatin 100,000 units) orally three times daily after meals. Each tablet should be allowed to dissolve slowly in the mouth.
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.

"The risk or severity of adverse effects can be increased when Terconazole is combined with Nimesulide."
Clinical Note

Plasma half-life is not measurable due to negligible systemic absorption. Topical or oral administration results in local action only; no systemic half-life is clinically relevant.
Terminal elimination half-life is approximately 25-37 hours, allowing once-daily dosing for vaginal infections.
Nystatin is not absorbed from the gastrointestinal tract, intact skin, or mucous membranes. After oral administration, it is excreted almost entirely unchanged in feces (over 99%). Minimal renal excretion occurs (less than 1%).
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.
