What is the pharmacological action of Ketoconazole?
Pharmacologically, ketoconazole is a pyrrole antifungal agent, which has antibacterial effect on deeply infected fungi and Trichophyton. Ketoconazole powder has a weak effect on Aspergillus, Sporothrix schenckii, some dark spore families, Mucor and so on. Ketoconazole interferes with the activity of cytochrome P-450, thus inhibiting the biosynthesis of ergosterol, the main sterol in fungal cell membrane, damaging fungal cell membrane and changing its permeability, resulting in the leakage of important intracellular substances. Ketoconazole can inhibit the biosynthesis of triacylglycerol and phospholipids of fungi, inhibit the activities of oxidase and peroxidase, cause the accumulation of hydrogen peroxide in cells, and lead to the degeneration of cell ultrastructure and cell necrosis. Candida albicans can inhibit its transformation from spore to invasive mycelium.

The differences between fluconazole and ketoconazole mainly lie in different directions of use, different pharmacological effects and different adverse reactions.
1, the use direction is different
Fluconazole is mainly used for candidiasis and other forms of invasive candidiasis. Ketoconazole is mainly used for superficial fungal infections.

2. Liver function should be checked regularly before and during use. The increase of serum aminotransferase may not be accompanied by hepatitis symptoms, however, if the serum aminotransferase value continues to increase or aggravate, or accompanied by hepatotoxic symptoms, the use of Ketoconazole powder should be stopped.
3. This product can cause photosensitive reaction, so you should avoid being exposed to bright light for a long time during taking the medicine, and you can wear colored glasses.
