• Sources and Categories: Clotrimazole is an imidazole antimycotic agent discovered in the 1960s. It falls under the category of azole-type antifungal drugs.
• Chemical Composition and Structure: Clotrimazole has a specific chemical structure consisting of four aromatic rings, including an imidazole ring.
• Uses: Clotrimazole is widely used in medical applications and is available under various trade names. Its formulations for the treatment of vulvovaginal candidosis have been marketed for over 45 years.; Clotrimazole inhibits fungal cell growth by binding to the heme portion of cytochrome P-450 lanosterol 14α-demethylase enzyme, leading to inhibition of ergosterol formation and accumulation of toxic methylated sterols, ultimately stopping fungal cell growth.; Widely used for the treatment of tinea pedis, cutaneous mycoses, oropharyngeal candidosis, vulvovaginal candidosis, and Candida balanitis.
• History and Development: First registered as Canesten? in Germany in 1973, initially for the local treatment of vulvovaginal candidosis. Various formulations, including vaginal tablets, creams, and soft capsules, have been developed over the years.
• FDA Approval: Clotrimazole is FDA approved, with an approval date of 07/29/2004. It is available in various formulations, including topical lotions, powders, oral lozenges, and vaginal inserts/tablets, under different tradenames approved by the FDA. Clotrimazole is classified by the FDA as a class C drug in pregnancy risk classification. It is not known to cross the placenta.
