Terbicip 250 mg Tablet contains Terbinafine, a potent antifungal agent that works by inhibiting the synthesis of ergosterol, a crucial component of fungal cell membranes. By disrupting fungal cell membrane function, Terbinafine effectively kills the fungus and prevents its growth, leading to the resolution of fungal infections. This medication is commonly used to treat conditions such as athlete’s foot, jock itch, and fungal nail infections.
