 AB    1. The antiviral effect of azidothymidine (AZT) can be potentiated by
       acyclovir (ACV), and this drug association has been used in the
       management of HIV-infected patients. In the present study we examined
       the effects of such an association on rat pregnancy. 2. AZT (60 mg/kg
       b.w.) and ACV (60 mg/kg b.w.) were given to groups of pregnant rats once
       a day from the 1st to the 20th day of gestation. 3. Maternal body weight
       gain was severely affected by ACV; this effect was attenuated in rats
       treated with AZT+ACV and was virtually absent with AZT alone. 4. The
       abortive action of ACV was markedly diminished in the group treated with
       the association AZT+ACV. 5. The deleterious effects of ACV on rat
       pregnancy are presumably due to its extraplacental actions, and these
       are, at least in part, counteracted by concomitant treatment with AZT.
