Posaconazole can effectively prevent invasive fungal infection. At present, although posaconazole injection has been approved by FDA (approved in March 2014), its status as a major preventive drug has not changed. Echinocandins (caspofungin, anifenin and micafungin) have a narrower antifungal spectrum than triazole and polyene drugs. They are mainly used to treat Candida infection. They have the advantages of good curative effect and significant safety, but non oral dosage form is one of their disadvantages. Polyene drugs (amphotericin B and its liposomes) are no longer the "gold standard" drugs for the treatment of deep fungal infection. The main reason for the decline of the treatment status of polyene drugs is its significant adverse reactions.
Posaconazole is derived from itraconazole. Phase III clinical trial is currently under way. The pharmacological effect is the same as that of azole drugs, but compared with itraconazole, it has a stronger inhibitory effect on sterol C14 demethylation, especially on Aspergillus.
For patients with invasive aspergillosis refractory to amphotericin B or itraconazole or patients who cannot tolerate these drugs.
The adverse reactions of this product are similar to other azole drugs. The most common treatment-related serious adverse reactions are bilirubinemia, elevated transaminase, hepatocyte damage, nausea and vomiting.
