Ritodrine hydrochloride was administered parenterally to pregnant ewes during spontaneous or oxytocin-induced uterine activity. The effects of ritodrine on the uterus and cardiovasculature were assessed both with and without simultaneous administration of either alpha or beta blockade. Ritodrine was found to be an effective inhibitor of both spontaneous and induced uterine activity. Ritodrine did cause maternal tachycardia but no significant hypotension. Alpha-adrenergic blockade did not influence the effects of ritodrine. Beta blockade with propranolol reversed the uterine and cardiovascular effects of ritodrine, whereas beta blockade with practolol reversed the cardiovascular effects without interfering with the inhibition of uterine activity produced by ritodrine.

Isolated rat uterus preparations were used in this study. Ritodrine hydrochloride (Rit), isoxsuprine (Isox), and spironolactone (SP) were applied on the uterus which has spontaneous activity. In similar doses they produced various inhibitory effects. Also, when oxytocin (Oxt) or acetylcholine (Ach) was conducted to the isolated preparations, contractions with high tonus and low amplitude occurred. On this model we investigated the inhibitory effect of spironolactone on the contractions. We conclude that spironolactone can be utilized on the uterus as a uterine contraction inhibitory agent in well regulated doses.
