Drug information of Clotrimazole


Clotrimazole

Drug group:

Clotrimazole is used to treat yeast infections of the vagina, mouth, and skin such as athlete's foot, jock itch, and body ringworm. It can also be used to prevent oral thrush in certain patients.

Mechanism of effect

Clotrimazole Cream is an antifungal agent. It kills sensitive fungi by binding to the fungal cell membrane and weakening it. This allows the cell contents to leak out and results in the death of the fungus.

Pharmacodynamic

An imidazole derivative with a broad spectrum of antimycotic activity. It inhibits biosynthesis of the sterol ergostol, an important component of fungal cell membranes. Its action leads to increased membrane permeability and apparent disruption of enzyme systems bound to the membrane.

Pharmacokinetics

Absorption : Negligible through intact skin (3-10% absorbed with intravaginal dose)
Time to peak: ~24 hr (vaginal cream)

Dosage

Apply clotrimazole topical in a quantity sufficient to cover the affected area and immediately surrounding skin twice a day for 2 to 4 weeks, depending on the nature and severity of the infection.
