Ketoconazole Esteve

Ketoconazole, the active ingredient in Ketoconazole Esteve, is an imidazole antifungal presented as an oral dosage form for systemic use. It treats a range of susceptible fungal infections, including systemic candidiasis, dermatophyte infections, blastomycosis and histoplasmosis, in adult patients. The drug exerts its effect by inhibiting fungal sterol synthesis, thereby limiting growth of pathogenic yeasts and molds.

GNH USA supplies Ketoconazole Esteve as a licensed, GDP‑compliant international pharmaceutical supplier serving hospitals, transplant centres, oncology centres, pharmacies, clinics, and research institutions worldwide.

Ketoconazole is used to treat fungal infections by targeting organisms that are susceptible to imidazole antifungal therapy.

Systemic candidiasis: eradication of invasive Candida species. Dermatophyte infections: clearance of skin and nail infections caused by dermatophytes. Blastomycosis: treatment of pulmonary and disseminated Blastomyces dermatitidis infection. Histoplasmosis: management of acute and chronic Histoplasma capsulatum disease. Other susceptible fungal infections: therapy for rare or resistant fungal pathogens as indicated.

Ketoconazole may cause a range of adverse reactions, from mild to severe.

Common Side Effects: - Nausea and vomiting. - Abdominal discomfort or pain. - Headache. - Rash or pruritus. - Elevated liver enzymes.

Serious or Rare Side Effects: - Hepatotoxicity, including severe liver injury. - Adrenal insufficiency due to inhibition of steroid synthesis. - QT interval prolongation and cardiac arrhythmias.

Before initiating therapy, clinicians should consider several safety measures.

Monitor liver function: obtain baseline and periodic hepatic enzyme tests. Assess for drug interactions: review concomitant CYP450 substrates and inhibitors. Avoid in patients with known hypersensitivity to imidazole antifungals. Use with caution in individuals with cardiac disease or electrolyte disturbances. Store at room temperature: keep in the original container, protect from moisture.

Ketoconazole has a notable interaction profile that requires careful management.

Major Interactions (Avoid): - CYP3A4 substrates (e.g., certain statins): increased risk of toxicity. - CYP2C9 substrates (e.g., warfarin): enhanced anticoagulant effect. - Ergot alkaloids: risk of severe vasospasm and ischemia.

Moderate Interactions (Monitor Closely): - Oral contraceptives: reduced hormonal efficacy. - Antacids or H2 blockers: decreased ketoconazole absorption. - Rifampin: lowered ketoconazole plasma concentrations.
