[Pharmacokinetics of amprenavir in HIV-1 patients with renal insufficiency].

Amprenavir is an HIV-1 protease inhibitor which is hepatically metabolized (>80%) with a low renal elimination. It has thus been suggested that no dosage adjustment is necessary in patients with renal dysfunction. However, no data are available on the pharmacokinetics of amprenavir in patients with renal insufficiency. We report on the pharmacokinetics of amprenavir in two HIV patients with severe and end-stage renal insufficiency. Amprenavir pharmacokinetics did not differ in our patients as compared with normal renal function subjects. Furthermore, amprenavir was not dialysable (FHD<25%). As a result, the drug may be administered at its normal dose in patients with renal failure, even when severe. In dialysis patients, amprenavir may be administered before or after the session.
