Human Oxytocin

CAS 50-56-6 · Obstetric & Pharmaceutical Applications

Human Oxytocin (CAS 50-56-6) is an indispensable hormone and active pharmaceutical ingredient (API) widely used in obstetrics for labor induction, postpartum hemorrhage control, and lactation support. Its powerful and selective action on uterine smooth muscle makes oxytocin a cornerstone therapy in maternal healthcare.

Manufactured under GMP-certified conditions with strict quality assurance, Human Oxytocin delivers reliable performance for pharmaceutical manufacturers, hospitals, and research institutions worldwide.

Human Oxytocin is a synthetic equivalent of the naturally occurring hormone produced by the posterior pituitary gland . It selectively stimulates uterine smooth muscle and mammary glands, supporting childbirth and lactation.

Physiological Role & Mechanism of Action

Oxytocin sensitivity increases progressively throughout pregnancy, reaching its peak at the onset of labor due to rising estrogen levels.

▸ Early pregnancy: low uterine sensitivity
▸ Mid-pregnancy: minimal responsiveness
▸ Late pregnancy: sharply increased sensitivity
▸ Labor onset: peak uterine responsiveness

Oxytocin binds to specific receptors on uterine smooth muscle , triggering stronger and more coordinated contractions, increased uterine tone, and efficient labor progression. It also stimulates the milk let-down reflex by acting on mammary glands.

Clinical & Pharmaceutical Applications

▸Induction and augmentation of labor
▸ Prevention and control of postpartum hemorrhage (PPH)
▸ Management of incomplete or missed miscarriage
▸ Stimulation of lactation and milk ejection
▸ Injectable formulations and hormonal research
