Popis: Background Pregnancy affects the pharmacokinetics of most protease inhibitors. Saquinavir, when administered in a tablet formulation, has not been studied extensively in this setting. Methods A pharmacokinetic, prospective, multicentre trial of HIV type-1-infected pregnant women treated with saquinavir (500 mg tablets) boosted with ritonavir at a dose of 1,000/100 mg twice daily plus a nucleoside backbone was conducted. Pharmacokinetic curves were recorded for 12 h in the second trimester (week 20 ±2), the third trimester (week 33 ±2) and post-partum (weeks 4–6). Blood was sampled pre-dosing and at 1, 2, 3, 4, 6, 8, 10 and 12 h post-dosing. Pharmacokinetic parameters were calculated using WinNonlin software version 4.1. Results A total of 37 women were included in the analysis. Mean (±sd) values for saquinavir area under the curve (AUC0–12h) were 23.47 h•mg/l (11.92) at week 20 ( n=16), 23.65 h•mg/l (9.07) at week 33 ( n=31) and 25.00 h•mg/l (11.81) post-partum ( n=9). There was no significant difference in the saquinavir AUC0–12h when comparing the data during pregnancy and post-partum. Subtherapeutic plasma concentrations of saquinavir (defined as Conclusions Saquinavir exposure in the new tablet formulation generates adequate saquinavir concentrations throughout the course of pregnancy and is safe to use; therefore, no dose adjustment during pregnancy is needed.
