What is itraconazole for dogs?

Specifically, it works by disrupting fungal membrane synthesis. It is useful against Malassezia, Candida, Histoplasma capsulatum, Cryptococcus, Blastomyces, Sporothrix or Coccidiodes.
It is considered an effective drug because, until now, the resistance that fungi have shown against azoles is developing slowly. In addition, itraconazole is well absorbed by the body and, after oral administration, its maximum concentration is reached within a few hours. It reaches the skin and nails in a significant quantity and persists in the tissues for weeks. It is absorbed in the small intestine, metabolized in the liver, and eliminated in the urine and bile.
