Overview

The molecular formula is C 18 H 14 Cl 4 N 2 O•HNO 3 ; the molecular weight is 479.
Mechanism of Action
CLINICAL PHARMACOLOGY Miconazole nitrate exhibits fungicidal activity in vitro against species of the genus Candida. The pharmacologic mode of action is unknown. Following intravaginal administration of miconazole nitrate, small amounts are absorbed. Administration of a single dose of miconazole nitrate vaginal suppositories (100 mg) to healthy subjects resulted in total recovery from the urine and feces of 0 . 85% (±0 . 43%) of the administered dose. Animal studies indicate that the drug crossed the placenta and doses above those used in humans result in embryo and fetotoxicity (80 mg/kg, orally), although this has not been reported in human subjects (See PRECAUTIONS ).
