Oxytocin produces vasodilation of vascular smooth muscle, increasing renal, coronary, and cerebral blood flow. Blood pressure is usually unchanged, but following iv administration of very large doses or undiluted solutions, blood pressure may decrease transiently, and tachycardia and an increase in cardiac output may be reflexly induced.

Oxytocin is produced and stored in the posterior pituitary gland, where the peptide is thought to remain in vesicles until released as the nine amino acid form. However, the molecule also may be released from axons within the brain and spinal cord (central nervous system) 19 , as well as from the neuronal soma and dendrites or by diffusion ...
