Maternal and fetal effects of uterine stimulants and relaxants.

: There are numerous pharmacologic agents available for either the stimulation or relaxation of the gravid uterus. Although these drugs have been in use for many years, recent advances have made their employment more desirable and therefore more frequent. While many of these drugs obtain the desired effect, all of them have side effects that may be either beneficial or adverse to the mother or fetus, or to both. It is important that those who are administering these drugs understand the complete range of effects they may evoke.
