Treatment of Chronic Oral Candidiasis with Clotrimazole Troches

Abstract

Twenty patients with chronic oral candidiasis were assigned by random allocation to a two-week course of either 10-mg clotrimazole buccal troches or placebo taken five times daily in a double-blind clinical trial. Each of the 10 recipients of clotrimazole had marked regression of symptoms and mucosal lesions, and in nine patients potassium hydroxide preparations and cultures of mucosal scrapings gave no evidence of candidiasis. In contrast, only one of the 10 patients receiving placebo showed any improvement. The clinical outcome in the clotrimazole-treated group was significantly more favorable (P<0.001) than in the group receiving placebo. No adverse reactions to the drug were observed.
