Voriconazole, sold under the brand name Vfend among others, is an antifungal medication used to treat a number of fungal infections. [5] This includes aspergillosis , candidiasis , coccidioidomycosis , histoplasmosis , penicilliosis , and infections by Scedosporium or Fusarium . [ 5 ]
Voriconazole is also being studied in salvage therapy for refractory cases. A case report indicated that voriconazole in combination with amphotericin B as salvage therapy for disseminated coccidioidomycosis was successful. Several case reports have studied caspofungin, with differing results. Caspofungin 50 mg/day following administration of ...
Itraconazole has a broader spectrum of activity than fluconazole (but not as broad as voriconazole or posaconazole). In particular, it is active against Aspergillus, which fluconazole is not. The mechanism of action of itraconazole is the same as the other azole antifungals: it inhibits the fungal-mediated synthesis of ergosterol .
Second-generation triazoles, including voriconazole, posaconazole and ravuconazole, are more potent and more active against resistant pathogens. [ 2 ] For wood preservation , other azoles such as propiconazole , tebuconazole and cyproconazole , are used as antifungal agents in several wood products or structures, with or without the addition of ...
An antifungal medication, also known as an antimycotic medication, is a pharmaceutical fungicide or fungistatic used to treat and prevent mycosis such as athlete's foot, ringworm, candidiasis (thrush), serious systemic infections such as cryptococcal meningitis, and others.
ATC code J02 Antimycotics for systemic use is a therapeutic subgroup of the Anatomical Therapeutic Chemical Classification System, a system of alphanumeric codes developed by the World Health Organization (WHO) for the classification of drugs and other medical products.
It also has decreased in vitro susceptibilities to multiple antifungals, including amphotericin B, itraconazole, voriconazole, and caspofungin. Aspergillus lentulus is an opportunistic human pathogen that causes invasive aspergillosis with high mortality rates. It has been isolated from clinical and environmental sources.
Posaconazole is absorbed within three to five hours. It is predominantly eliminated through the liver, and has a half-life of about 35 hours. Oral administration of posaconazole taken with a high-fat meal exceeds 90% bioavailability and increases the concentration by four times compared to fasting state.
