Quizplus · Accepted Answer

Beta₂ agonists cause relaxation of uterine muscle,slowing or stopping the contractions that precipitate labor. An alpha₂ agonist would have effects on the heart and arterioles. Anticholinergic drugs generally are given for their effects on the urinary and GI tracts and do not affect uterine muscle. A beta₂ antagonist would cause increased constriction of uterine muscle.
