Keto-AZ Lotion is a topical antifungal formulation containing Ketoconazole 2% w/v and Zinc Pyrithione 1% w/v, indicated for the treatment of various superficial fungal infections of the skin. Ketoconazole, an imidazole antifungal agent, acts by inhibiting the synthesis of ergosterol, an essential component of fungal cell membranes, thereby disrupting membrane integrity and leading to fungal cell death. Zinc Pyrithione exhibits broad-spectrum antimicrobial activity, including antifungal and antibacterial effects, by interfering with membrane transport and cellular metabolism. The combination of these active ingredients provides enhanced efficacy against dermatophytes, yeasts such as Malassezia species, and other pathogenic fungi responsible for conditions like seborrheic dermatitis, tinea versicolor, and pityriasis capitis. Keto-AZ Lotion is applied topically to the affected area once or twice daily as directed by a healthcare professional. It is generally well tolerated, with minimal adverse effects; however, mild local irritation, burning, or dryness may occur. Use should be avoided in individuals with known hypersensitivity to any component of the formulation. Continued use as prescribed is essential to achieve optimal therapeutic outcomes and prevent recurrence. Consultation with a healthcare provider is recommended prior to initiation of therapy.
