Ketonext Shampoo contains Ketoconazole 2% w/v, an imidazole antifungal agent effective in the treatment of various fungal infections of the scalp. Ketoconazole exerts its therapeutic action by inhibiting the synthesis of ergosterol, a critical component of fungal cell membranes, thereby disrupting membrane integrity and leading to fungal cell death. This shampoo is primarily indicated for the management of seborrheic dermatitis and dandruff caused by Malassezia species, as well as other superficial fungal infections affecting the scalp. Ketonext Shampoo helps to reduce scaling, itching, and inflammation associated with these conditions. It is applied topically to the affected area, typically used two to three times weekly for a duration determined by the severity of the condition and clinical response. The formulation is designed for ease of use and minimal irritation, making it suitable for adult patients and children above the age of two. Adverse effects are generally mild and may include localized burning, itching, or dryness. Contraindications include hypersensitivity to ketoconazole or any excipients in the formulation. Use with caution in patients with open wounds or severe skin conditions. Ketonext Shampoo should be used as part of a comprehensive scalp care regimen to achieve optimal therapeutic outcomes.
