Ketoconazole Tablets

Name: Ketoconazole Tablets

Indications and Usage for Ketoconazole Tablets

Ketoconazole Tablets are not indicated for treatment of onychomycosis, cutaneous dermatophyte infections, or Candida infections.

Ketoconazole Tablets should be used only when other effective antifungal therapy is not available or tolerated and the potential benefits are considered to outweigh the potential risks.

Ketoconazole Tablets are indicated for the treatment of the following systemic fungal infections in patients who have failed or who are intolerant to other therapies: blastomycosis, coccidioidomycosis, histoplasmosis, chromomycosis, and paracoccidioidomycosis. Ketoconazole Tablets should not be used for fungal meningitis because it penetrates poorly into the cerebrospinal fluid.

Contraindications

Drug Interactions

Coadministration of a number of CYP3A4 substrates such as dofetilide, quinidine, cisapride and pimozide is contraindicated with Ketoconazole Tablets. Coadministration with ketoconazole can cause elevated plasma concentrations of these drugs and may increase or prolong both therapeutic and adverse effects to such an extent that a potentially serious adverse reaction may occur. For example, increased plasma concentrations of some of these drugs can lead to QT prolongation and sometimes

resulting in life-threatening ventricular tachyarrhythmias including occurrences of Torsades de pointes, a potentially fatal arrhythmia. (See PRECAUTIONS: Drug Interactions.)

Additionally, the following other drugs are contraindicated with Ketoconazole Tablets: methadone, disopyramide, dronedarone, ergot alkaloids such as dihydroergotamine, ergometrine, ergotamine, methylergometrine, irinotecan, lurasidone, oral midazolam, alprazolam, triazolam, felodipine, nisoldipine, ranolazine, tolvaptan, eplerenone, lovastatin, simvastatin and colchicine. (See PRECAUTIONS: Drug Interactions.)

Enhanced Sedation

Coadministration of Ketoconazole Tablets with oral midazolam, oral triazolam or alprazolam has resulted in elevated plasma concentrations of these drugs. This may potentiate and prolong hypnotic and sedative effects, especially with repeated dosing or chronic administration of these agents. Concomitant administration of Ketoconazole Tablets with oral triazolam, oral midazolam, or alprazolam is contraindicated. (See PRECAUTIONS: Drug Interactions.)

Myopathy

Coadministration of CYP3A4 metabolized HMG-CoA reductase inhibitors such as simvastatin, and lovastatin is contraindicated with Ketoconazole Tablets. (See PRECAUTIONS: Drug Interactions.)

Ergotism

Concomitant administration of ergot alkaloids such as dihydroergotamine and ergotamine with Ketoconazole Tablets is contraindicated. (See PRECAUTIONS: Drug Interactions.)

Liver Disease

The use of Ketoconazole Tablets is contraindicated in patients with acute or chronic liver disease.

Hypersensitivity

Ketoconazole is contraindicated in patients who have shown hypersensitivity to the drug.
