Wokbin 250 Tablet contains Terbinafine 250 mg, an antifungal agent primarily used for the treatment of various fungal infections. Terbinafine belongs to the allylamine class of antifungals and acts by inhibiting the enzyme squalene epoxidase, which is essential for the synthesis of ergosterol, a key component of fungal cell membranes. This disruption leads to increased cellular permeability and ultimately fungal cell death. Wokbin 250 is indicated for the treatment of dermatophyte infections such as tinea corporis, tinea cruris, tinea pedis, and onychomycosis caused by susceptible strains of fungi. The tablet is administered orally, allowing systemic distribution to effectively target infections involving skin, hair, and nails. Wokbin 250 is generally well tolerated; however, patients should be monitored for potential adverse effects including gastrointestinal disturbances, headache, rash, and, rarely, hepatotoxicity. Liver function tests are recommended prior to and during prolonged therapy. It is contraindicated in patients with known hypersensitivity to terbinafine or any of its excipients and should be used with caution in those with pre-existing liver or kidney impairment. Wokbin 250 offers a convenient and effective option for managing fungal infections with a typical treatment duration varying based on the infection site and severity.
