[Studies on the kinetics of methaqualone during the late stage of pregnancy (author's transl)].

After oral administration of 0.4 g of methaqualone to pregnant and non-pregnant women, the authors stated that the half-life of this drug was significantly reduced during the last trimester of pregnancy. The two experimental groups showed no significant differences in the volume of distribution and the fictitious initial concentration. The commonly used therapeutical dosages are not likely to produce increased blood levels during normal pregnancy.
