Nizoral (Ketoconazole)

Ketoconazole, the active ingredient in Nizoral, is an azole antifungal presented as a topical formulation for skin use. It treats fungal skin infections such as athlete’s foot, ringworm and seborrheic dermatitis in adults and children, and is indicated for use on the scalp, body and intertriginous areas. The formulation is designed for once‑daily application to affected sites.

GNH USA supplies Nizoral as a licensed, GDP‑compliant international pharmaceutical supplier serving hospitals, pharmacies and clinics worldwide. The company adheres to stringent quality standards and provides regulatory‑approved batches for global distribution.

Nizoral (ketoconazole) is used to treat superficial fungal infections affecting the skin and scalp.

- Tinea corporis: reduces erythema and scaling caused by dermatophyte infection of the body. - Tinea cruris: alleviates itching and rash in the groin area due to fungal overgrowth. - Tinea pedis: clears foot skin infection, decreasing scaling and odor. - Seborrheic dermatitis: controls flaking and redness on the scalp and face. - Pityriasis versicolor: eliminates yeast‑induced discoloration and hyperpigmented patches.

Topical ketoconazole may cause local or systemic adverse reactions, most of which are mild and reversible.

Common Side Effects: - Burning sensation: mild stinging at the application site. - Itching: transient pruritus on treated skin. - Redness: localized erythema.

Serious or Rare Side Effects: - Allergic reaction: swelling, hives, or difficulty breathing. - Severe dermatitis: extensive rash or blistering. - Hepatotoxicity: rare systemic absorption leading to liver enzyme elevation.

Before using Nizoral, consider the following safety measures to minimize risks.

- Avoid use on broken skin: apply only to intact epidermis. - Limit duration: do not exceed recommended treatment period without medical advice. - Monitor for irritation: discontinue if severe burning or rash develops. - Caution in liver disease: inform healthcare provider of existing hepatic conditions. - Pregnancy and lactation: discuss risks with a physician before use. - Store below 25°C: keep in original packaging, protect from moisture and direct sunlight.

Ketoconazole can affect the activity of other medicines; interactions are classified by clinical significance.

Major Interactions (Avoid): - Systemic antifungals: concurrent use may increase risk of hepatotoxicity. - CYP3A4 substrates: topical ketoconazole may modestly increase plasma levels of drugs metabolized by CYP3A4, such as certain statins. - Hormonal contraceptives: may reduce efficacy, requiring additional contraceptive measures.

Moderate Interactions (Monitor Closely): - Topical corticosteroids: may enhance skin absorption, increasing local irritation. - Warfarin: monitor INR as ketoconazole can affect anticoagulant metabolism. - Antiretrovirals: observe for altered levels of protease inhibitors.
