Ketoconazole Esteve

Ketoconazole, the active ingredient in Ketoconazole Esteve, is an Imidazole antifungal presented as an unknown/unknown for Oral use. It treats systemic fungal infections such as blastomycosis, histoplasmosis, and candidiasis in adult patients who require systemic therapy.

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

Ketoconazole is used to treat systemic fungal infections by targeting pathogenic yeasts and molds. - Blastomycosis: eradicates Blastomyces dermatitidis and resolves pulmonary and disseminated disease. - Histoplasmosis: eliminates Histoplasma capsulatum, improving symptoms of acute and chronic infection. - Candidiasis: clears systemic Candida species, preventing organ involvement and bloodstream infection.

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

Common Side Effects: - Nausea: mild to moderate stomach upset. - Vomiting: occasional episodes after dosing. - Abdominal pain: cramping or discomfort in the gastrointestinal tract. - Headache: transient headache during therapy. - Rash: mild skin erythema or itching. - Elevated liver enzymes: mild transaminase increase.

Serious or Rare Side Effects: - Hepatotoxicity: severe liver injury requiring monitoring. - Stevens‑Johnson syndrome or toxic epidermal necrolysis: life‑threatening skin reactions. - Adrenal insufficiency: suppression of cortisol synthesis. - QT interval prolongation: risk of cardiac arrhythmia. - Severe hypersensitivity: anaphylaxis or angioedema.

Before initiating therapy, clinicians should consider several safety measures. - Liver function monitoring: assess baseline transaminases and repeat during treatment. - Drug interaction review: evaluate concomitant medications metabolized by CYP3A4. - Hypersensitivity avoidance: discontinue if rash or allergic reaction occurs. - Cardiac risk assessment: avoid in patients with known QT prolongation. - Pregnancy and lactation: weigh benefits against potential fetal risk; use only if clearly needed. - Store at ambient temperature: keep below 25 °C in the original container, protect from moisture and light.

Ketoconazole interacts with several drug classes and may alter their plasma levels.

Major Interactions (Avoid): - CYP3A4 substrates (e.g., certain statins, midazolam): risk of toxicity due to inhibited metabolism. - Oral contraceptives: reduced efficacy, leading to possible unintended pregnancy. - Anticoagulants (warfarin): increased INR and bleeding risk.

Moderate Interactions (Monitor Closely): - QT‑prolonging agents (e.g., quinidine, sotalol): additive effect on cardiac conduction. - Hepatotoxic drugs (e.g., isoniazid, acetaminophen): heightened liver injury potential. - Immunosuppressants (e.g., cyclosporine): possible increased levels requiring dose adjustment.
