FULVICIN P/G 330 vs NYSTOP
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Fulvicin P/G 330 contains griseofulvin, which inhibits fungal cell mitosis by disrupting the microtubule function, binding to tubulin and preventing assembly of spindle fibers during metaphase.
Nystatin binds to ergosterol in fungal cell membranes, forming pores that disrupt membrane integrity, leading to leakage of intracellular ions and cell death.
330 mg orally once daily with fatty meal to enhance absorption.
Apply a thin layer to affected area 2-3 times daily or as directed. Nystatin is not absorbed systemically; topical use only.

Terminal half-life approximately 9-22 hours in adults, with a mean of ~13 hours. Clinical context: steady-state achieved in 2-3 days; may guide dosing interval.
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.
Primarily hepatic metabolism; <1% excreted unchanged in urine. Biliary/fecal excretion of metabolites: ~36% in feces, ~13% in urine.
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.
