Key points

  • An imidazole antifungal kept in reserve for severe systemic infections that other options could not resolve.
  • Also affects cortisol production, so clinicians may use it to help regulate hormone levels in Cushing’s syndrome.
  • Liver function test changes are possible during treatment, and any unexpected new symptom should be reported to a provider.

What is Ketoconazole?

Ketoconazole is a synthetic imidazole derivative that functions by stopping the growth of fungi. It serves as a targeted therapy, usually reserved for situations where typical treatments have failed or are not suitable for the patient. Because its mechanism affects fungal cell walls, manufacturers produce it in specific concentrations to address underlying systemic issues.

What Ketoconazole is used for

This medication is primarily utilised as a treatment for Severe Systemic Fungal Infections and Severe Fungal Infections. In addition to its antimicrobial properties, it affects the production of cortisol. For this reason, clinicians may also use it in the management of Cushing’s Syndrome to help regulate hormonal balance in patients.

How does Ketoconazole work?

Ketoconazole stops fungi from making ergosterol, a substance key for the integrity of fungal cell membranes. Without this component, the fungal cell structure becomes compromised, which inhibits the ability of the fungus to grow or spread. This systemic action allows it to address infections that are otherwise difficult to reach with topical or less potent options.

Ketoconazole brands and forms

The available catalogue for this ingredient focuses on the oral Tablet formulation. Choosing between products depends on the required strength and the manufacturing standards of the specific brand, such as Nizoral.
