Oxytocin is a synthetic analogue of the peptide hormone of the posterior pituitary gland. Under the influence of oxytocin, the permeability of cell membranes increases, the resting potential decreases, and the excitability of the muscles of the uterus increases. It has a stimulating effect on the smooth muscles of the uterus, increases the contractility of the myometrium, increases the frequency and amplitude of contractions, in high concentrations helps to increase the tone of the uterus.

Oxytocin stimulates milk secretion by increasing prolactin production by the anterior pituitary gland. Reduces myoepithelial cells around the alveoli of the mammary gland, stimulates the flow of milk into the large ducts and sinuses.
