Merazol

Ketoconazole, the active ingredient in Merazol, is an azole antifungal presented as a topical formulation for cutaneous use. It is employed to treat superficial fungal infections of the skin, such as athlete’s foot, ringworm, and seborrheic dermatitis, in adult and pediatric patients.

GNH USA supplies Merazol as a licensed, GDP‑compliant international pharmaceutical supplier serving hospitals, pharmacies and clinics worldwide, ensuring quality assurance, regulatory compliance and reliable logistics for consistent product availability across global markets.

Ketoconazole is an azole antifungal that interferes with fungal cell membrane synthesis, making it effective for a range of superficial dermatophyte and yeast infections. - Tinea corporis: reduces lesion size and clears the infection on the body. - Tinea cruris: alleviates itching and eliminates fungal growth in the groin area. - Tinea pedis: treats athlete’s foot by eradicating dermatophytes on the feet. - Seborrheic dermatitis: controls flaking and redness caused by Malassezia species. - Pityriasis versicolor: clears discolored patches by eliminating the causative yeast.

Ketoconazole topical preparations may cause local or systemic adverse reactions, although most are mild and reversible.

Common Side Effects: - Skin irritation: redness, burning or itching at the application site. - Dryness: localized skin dryness or peeling. - Pruritus: mild itching unrelated to infection. - Contact dermatitis: allergic skin reaction in sensitive individuals.

Serious or Rare Side Effects: - Hepatotoxicity: rare systemic absorption leading to liver enzyme elevation. - Severe allergic reaction: urticaria or angioedema requiring medical attention. - Stevens‑Johnson syndrome: extremely rare but serious skin disorder. - Photosensitivity: increased sensitivity to sunlight causing rash.

When using Merazol, consider the following precautions to ensure safe and effective therapy. - Avoid use on broken skin: apply only to intact epidermis to reduce systemic absorption. - Limit duration: follow prescriber instructions and discontinue after recommended treatment period. - Concomitant liver disease: use with caution in patients with hepatic impairment. - Pediatric use: safety not established for children under 2 years; consult healthcare professional. - Pregnancy and lactation: safety not established; discuss risks with a physician. - Store at ambient temperature: keep below 25 °C, protect from moisture and direct sunlight in original container.

Ketoconazole may interact with other medicines; awareness of these interactions helps prevent reduced efficacy or increased toxicity.

Major Interactions (Avoid): - Systemic antifungals: concurrent use can increase risk of hepatotoxicity. - CYP3A4 substrates: strong inhibitors may raise ketoconazole levels, leading to toxicity. - Warfarin: may potentiate anticoagulant effect, increasing bleeding risk.

Moderate Interactions (Monitor Closely): - Topical corticosteroids: may mask signs of infection, delaying assessment. - Hormonal contraceptives: ketoconazole can reduce effectiveness; consider backup method. - Antacids containing aluminum or magnesium: may decrease local absorption if applied immediately after.
