Usage

Function of Posaconazole

Posaconazole is a triazole antifungal drug, which can inhibit the synthesis of fungal cell membranes, thereby producing antifungal effects. It can mainly be used to prevent invasive Aspergillus and Candida infections, and is suitable for the prevention of acute Aspergillus and Candida infections caused by severe immunodeficiency in patients 13 years of age and older.

After the above patients received hematopoietic stem cell transplantation, patients with graft-versus-host disease, or patients with hematological malignancies with prolonged neutropenia caused by chemotherapy, so this drug is mainly used to prevent invasive Aspergillus and Candida Infection.
