Terconazole--a new antifungal agent for vulvovaginal candidiasis.
Terconazole is a new broad-spectrum antifungal agent for the treatment of vulvovaginal candidiasis. Instead of an imidazole structure, terconazole contains a triazole ring, a structure developed specifically to improve antifungal activity. Clinical studies of this antifungal agent have involved 5,500 women worldwide and a number of terconazole formulations, including 80-mg vaginal suppositories and 0.4% vaginal cream. The highlights of several large, major studies are discussed in this review article. In European studies, mycologic cure rates for terconazole regimens approached or exceeded 90%. Speed of action was rapid, and relapse rates were low. In double-blind, multicenter studies conducted in the United States, clinical cure rates for 0.4% terconazole cream ranged from 86% to 96% and microbiologic cure rates from 77% to 91% at 8 to 10 days after therapy. Most patients remained free of positive signs and symptoms and microbiologic evidence of infection at 30 to 35 days posttherapy. Symptomatic relief tended to be more rapid for patients treated with 0.4% terconazole cream than for those treated with 2.0% miconazole nitrate cream. In US studies of 80-mg terconazole suppositories, clinical cure rates 8 to 10 days after therapy were between 89% and 92%, and microbiologic cure rates were between 80% and 85%. Relapse rates were also low with this form of therapy. No statistically significant differences were found between three days of treatment with 80-mg terconazole suppositories and seven days of treatment with 100-mg miconazole nitrate suppositories. This research demonstrates that terconazole is a fast-acting, highly effective, well-tolerated therapy for vulvovaginal candidiasis.
