Pharmacology: Pharmacodynamics: Clotrimazole (Trimacort) 1% Cream is a broad-spectrum, antifungal agent that is used for the treatment of dermal infections caused various species of pathogenic dermatophytes, yeast and Malassezia furfur.
Pharmacokinetics: Clotrimazole cream containing C-labelled Clotrimazole was administered intravaginally to five women (four without gynecological disorders and one with Candida vulvovaginitis). A maximum serum level of 0.01 mg/mL was found between 10 and 30 hours after administration.
Studies of urinary excretion have shown that less than 0.5% dermally applied Clotrimazole cream appears in the urine over a five-day period of observation. Faecal excretion, the route by which most of the absorbed drug likely to be eliminated, has not been studied in humans.
It is used topically in superficial candidiasis and in skin infections pityriasis versicolor and dermatophytosis. Clotrimazole is also indicated in the treatment of vulvovaginal candidiasis.
Apply sparingly to the affected area and rub it gently, two to three times daily.
Duration of treatment: the following recommendations are made: Cutaneous candidiasis 2 weeks, Dermatomycoses 3-4 weeks, Onychia and Paronychia due to C. albicans 4-8 weeks or more.
Regular application of Clotrimazole cream is essential for successful treatment and whether or not a cure is confirmed mycologically, treatment should be continued for two weeks after clinical signs have disappeared.
