Atazanavir atazanavir is a structural analog of the transition state during which the bond between a phenylalanine and proline is broken. Humans do not have any enzymes that break bonds between phenylalanine and proline, so this drug will not target human enzymes. Atazanavir is available as a 150 mg capsule, 200 mg capsule, 300 mg capsule, and 50 mg oral powder packet. The 300 mg capsule should reduce pill burden, as one 300 mg capsule may replace two 150 mg capsules. Atazanavir Atazanavir, sold under the trade name Reyataz among others, is an antiretroviral medication used to treat and prevent HIV/AIDS.
Drug-eluting stent drug-eluting stents to be licensed used durable coatings. The first generation coatings appear to have caused immunological reactions at times and some possibly led to thrombosis, which has driven experimentation and development of new coating approaches. The drug is mainly to inhibit neointimal growth (due to the proliferation of smooth muscle cells) that would cause restenosis. Much of the neointimal hyperplasia seems to be caused by inflammation. Hence, immunosuppressive and antiproliferative drugs are used. Sirolimus, paclitaxel, and everolimus were previously used for other medical applications and have been included in licensed DES.
