Keyzol Soap contains Ketoconazole 2% w/w, an antifungal agent effective in the treatment of various superficial fungal infections of the skin. Ketoconazole, an imidazole derivative, acts by inhibiting the synthesis of ergosterol, a vital component of fungal cell membranes, leading to increased membrane permeability and ultimately fungal cell death. Keyzol Soap is indicated for the management of dermatophytosis, pityriasis versicolor, seborrheic dermatitis, and other fungal infections caused by susceptible strains of fungi and yeasts. The soap formulation allows for topical application, facilitating direct contact with the affected area, thereby reducing fungal load and alleviating symptoms such as itching, scaling, and redness. It is recommended to use Keyzol Soap twice daily by lathering and applying to the affected area for 2 to 4 weeks or as directed by a healthcare professional. Caution should be exercised to avoid contact with eyes and mucous membranes. In case of irritation or hypersensitivity, use should be discontinued and medical advice sought. Keyzol Soap is not intended for systemic fungal infections and should be used under medical supervision. Proper hygiene and adherence to the prescribed regimen enhance therapeutic outcomes and minimize recurrence.
