Summary
Ketoconazole is an oral antifungal drug that works by inhibiting ergosterol synthesis in fungi. While effective for various fungal infections, more large-scale studies are needed to fully assess its long-term safety and efficacy.
Area of Science:
- Pharmacology
- Mycology
- Pharmacokinetics
Background:
- Ketoconazole is a novel imidazole derivative with oral antifungal activity.
- It functions by disrupting ergosterol synthesis, a critical component of fungal cell membranes.
Purpose of the Study:
- To review the pharmacology, microbiology, pharmacokinetics, clinical applications, adverse effects, and drug interactions of ketoconazole.
- To evaluate the efficacy and safety profile of this new antifungal agent.
Main Methods:
- Review of existing literature on ketoconazole.
- Analysis of pharmacokinetic data including absorption, distribution, metabolism, and excretion.
- Compilation of clinical data on approved and potential uses, as well as adverse effects.
Main Results:
- Ketoconazole is absorbed from the GI tract, with absorption influenced by gastric pH.
- It distributes widely in the body and is eliminated biphasically.
- Approved for treating various fungal infections like candidiasis and histoplasmosis; shows promise for others.
Conclusions:
- Ketoconazole is a promising oral antifungal agent effective against a range of fungi.
- Common side effects include nausea and vomiting; transient liver enzyme elevations can occur.
- Further large-scale comparative studies are required to establish definitive efficacy and long-term safety.
