Chlordantoin is primarily utilized as an antifungal agent, particularly in the treatment of superficial fungal infections. It is commonly found in topical formulations such as creams, ointments, and powders, which are applied directly to the affected areas of the skin. The compound works by inhibiting the growth of fungi, making it effective against conditions like athlete's foot, ringworm, and other dermatophyte infections. Its application is favored due to its localized action, minimizing systemic absorption and reducing the risk of side effects. Additionally, chlordantoin is sometimes incorporated into combination products with other antifungal or anti-inflammatory agents to enhance its therapeutic efficacy. Its ease of use and effectiveness in managing mild to moderate fungal infections make it a valuable option in dermatological care.
