The beta-2 adrenergic agonists act mainly on the smooth muscle of the vasculature, bronchial tree, intestines and uterus these agents also act on the liver stimulating glycogenolysis and release of glucose from the liver and muscle (particularly if used in high doses. Contraction of the myometrium (uterine smooth muscle) is regulated by multiple mediators, including beta-adrenergic agonists, oxytocin, and prostaglandins (fig 64–1) as a result, there are multiple ways in which drugs can suppress uterine activity.

Uterine excitability and contractility phasic contractions of the uterus occur due to spontaneous changes in electrical activity within myometrial cells, the mechanism of which is unknown, but which leads to action potentials and depolarization.

Drugs that bind to beta 2 receptors (beta 2 agonists) are used in the treatment of premature labour, this clinical application illustrates how beta 2 receptors mediate tocolysis on the uterine muscle ritodrine is an example of a tocolytic drug. In our studies the ach increased tension in the smooth muscle of the uterus, which was the highest in the strips of pregnant uterus, with a simultaneous decrease in amplitude moreover, the frequency of contractions in the strips of the uterus without embryos was higher as compared to the uterine horn with embryos.
