Ketoconazole Viatris (Ketoconazole)

Ketoconazole blocks the fungal enzyme 14α‑demethylase, which is essential for converting lanosterol to ergosterol, a vital component of the fungal cell membrane. By inhibiting this step, the drug disrupts membrane formation, leading to increased permeability and ultimately fungal cell death. The effect is localized to the skin where the product is applied.

The dosage and frequency of application are determined by the prescribing healthcare professional based on the specific infection, its severity, and the patient’s overall condition. Typically, a thin layer is applied to the affected area once or twice daily, but the exact regimen should follow the prescriber’s instructions.

Safety data for topical ketoconazole in pregnancy and lactation are limited. Women who are pregnant, planning to become pregnant, or breastfeeding should discuss potential risks and benefits with their healthcare provider before using the product. The prescriber will decide whether the treatment is appropriate.

To place an order, submit an enquiry on the product page at gnhindia.com, specifying the required quantity. GNH India works with hospitals, pharmacies, and procurement teams worldwide, and will request verification of trade or institutional credentials. The sales team then provides pricing, availability, shipping details (including any cold‑chain requirements), and assists with import documentation.

Ketoconazole belongs to the imidazole class, offering a broad spectrum against dermatophytes and yeasts. Compared with allylamine agents such as terbinafine, ketoconazole may have slightly slower clinical resolution but is effective for seborrheic dermatitis and pityriasis versicolor where Malassezia species predominate. Choice of therapy often depends on the specific organism, site of infection, and patient tolerance.

Store the product at room temperature, ideally below 25 °C, in its original container. Keep it away from excessive moisture and direct sunlight. Ensure the cap is tightly closed after each use to maintain product stability and prevent contamination.

Clean and gently dry the affected skin area before use. Apply a thin layer of the cream, lotion, or gel to the lesion and surrounding skin, gently massaging it in until it disappears. Follow the prescriber’s recommended frequency, usually once or twice daily, and continue treatment for the full course even if symptoms improve.

Although rare, serious adverse reactions can include severe allergic responses such as angioedema, extensive contact dermatitis, and, in exceptional cases, systemic absorption leading to liver toxicity. Patients should stop using the product and seek immediate medical attention if they experience swelling of the face, lips, or tongue, widespread rash, or signs of liver dysfunction such as jaundice.

Ketoconazole Viatris should be avoided in individuals with known hypersensitivity to ketoconazole or any other imidazole antifungal. It is also not recommended for use on severely damaged or broken skin, as increased systemic absorption may occur. Patients with pre‑existing liver disease should consult a physician before using any formulation that could be absorbed systemically.
