Kizter Tablet contains Terbinafine 250mg, an antifungal agent primarily indicated for the treatment of various fungal infections of the skin and nails. Terbinafine belongs to the allylamine class of antifungals and exerts its effect by inhibiting the enzyme squalene epoxidase, which is essential for ergosterol synthesis in fungal cell membranes. This disruption leads to increased cellular permeability and ultimately fungal cell death. Kizter Tablet is effective against dermatophytes, yeasts, and molds, making it suitable for conditions such as tinea corporis, tinea cruris, tinea pedis, and onychomycosis. The oral administration of Terbinafine ensures systemic distribution, allowing penetration into keratinized tissues where fungal infections commonly reside. The recommended dosage and duration of therapy depend on the type and severity of the infection, and treatment should be continued as prescribed to prevent recurrence. Common adverse effects may include gastrointestinal disturbances, headache, and rash, while rare but serious side effects such as hepatotoxicity require monitoring of liver function during prolonged therapy. Kizter Tablet should be used cautiously in patients with liver impairment and contraindicated in those with known hypersensitivity to Terbinafine or any component of the formulation. It is essential to follow medical advice and complete the full course of treatment for optimal outcomes.
