Increased concentrations of the inactive metabolite buprenorphine-3-glucuronide suggested that darunavir-ritonavir and fosamprenavir-ritonavir induced glucuronidation of buprenorphine[1].in vivo: Fosamprenavir-ritonavir administered with methadone did not alter plasma amprenavir pharmacokinetics compared with historical control data; nor did it alter the unbound R-methadone at 2 and 6 hours after methadone dosing. Pharmacodynamic indexes remained essentially unchanged after adding fosamprenavir-ritonavir to methadone [2]. After a high-fat meal compared with fasting, (1) the bioavailability of GW433908G suspension was decreased by 20% and Cmax by 41%, and (2) for GW433908G tablets, there was no influence on AUC(12% lower Cmax). After a low-fat meal compared with fasting, (1) there was bioequivalence for GW433908G tablets, but (2) bioavailability was decreased by 23% for amprenavir capsules (Cmax was also lower, by 46%) [3].Clinical trial: Study of an Investigational Regimen Including FDA Approved HIV Drugs In HIV-Infected Pediatric Subjects.
