Abstract

This study evaluates the safety, tolerance, and pharmacokinetics of stavudine (d4T) in human immunodeficiency virus (HIV)-infected zidovudine (ZDV)-intolerant/refusing pregnant women and of single-dose d4T in their infants. Women received d4T and lamivudine (3TC) from enrollment until labor. During labor, women received oral 3TC and either intravenous or oral d4T. Infants received ZDV and 3TC for 6 weeks and a single dose of oral d4T at weeks 1 and 6. Mean maternal antenatal d4T pharmacokinetics (terminal plasma half-life [T 1/2], 83.5 ± 16.8 min; area under the plasma-concentration time curve [AUC 0-∞], 81.6 ± 22.0 μg·min/mL; n = 6) were not significantly different from those during labor (T 1/2, 87.3 ± 24.7 min; AUC 0-∞, 88.1 ± 16.6 μg·min/ mL; n = 6). Umbilical-cord and maternal plasma concentrations were not significantly different from one another. The oral clearance of d4T in infants was significantly greater at week 6 versus week 1 (6.8 ± 1.0 vs. 5.6 ± 1.2 mL/min/kg). There were no toxicities, in women or infants, that required discontinuation or modification of the study drug. No infants had positive HIV viral diagnostic tests. d4T with or without 3TC is a potential alternative to ZDV for HIV-infected pregnant women.
