Amprenavir, new protease inhibitor, approved
Abstract
AIDS: A new protease inhibitor, amprenavir (Agenerase), has received FDA marketing approval. The approval was based on two 24-week controlled trials and safety data in more than 1,400 patients under FDA accelerated-approval rules. Amprenavir is approved for patients 4 years of age and older. The drug is taken twice daily, with or without food. Side effects include gastrointestinal disturbances, rashes, and oral paresthesia. Severe or life-threatening rashes have occurred in 1 percent of all patients. Pregnant women should not use the drug unless necessary. The drug was developed by Vertex Pharmaceuticals Inc. and is being marketed by Glaxo Wellcome. Some studies suggest that amprenavir is less likely than other protease inhibitors to be associated with lipid metabolism problems. It may have a resistance profile different from that of other protease inhibitors, and therefore may cause different cross resistance problems. Amprenavir appears to be synergistic with abacavir (Ziagen) in laboratory tests.
