Clotrimazole is a broad-spectrum antifungal agent used for the treatment of superficial infections caused by species of pathogenic dermatophytes, yeasts and Malassezia furfur. The mechanism of action involves inhibition of the synthesis of ergosterol, a major sterol in the fungal cell membrane. This leads to instability of the cell membrane and eventual death of the fungus.
Betamethasone dipropionate is a corticosteroid with anti-inflammatory, antipruritic, and vasoconstrictive properties. But the exact mechanism of action of corticosteroids is not clearly known.
