Product Overview

Oxytocin is a nine-amino-acid neuropeptide hormone that plays a fundamental role in uterine contraction, milk ejection, and various physiological functions including social cognition and stress responses. First discovered in 1906 and synthesized in 1953 as the first polypeptide hormone to be artificially produced, oxytocin remains a cornerstone pharmaceutical intermediate in reproductive health applications.

Our Oxytocin is supplied as a high-purity lyophilized powder, manufactured under strict quality control standards, suitable for pharmaceutical intermediate, research, and veterinary applications.

Mechanism of Action

Oxytocin acts primarily as a neuromodulator in the brain and as a hormone in the periphery. It is synthesized in the magnocellular neurons of the supraoptic (SON) and paraventricular nuclei (PVN) of the hypothalamus and is released into systemic circulation from axon terminals in the posterior pituitary.

The primary mechanisms include:

• Uterine Smooth Muscle Contraction: Binds to oxytocin receptors on uterine myometrial cells, inducing rhythmic contractions

• Mammary Gland Myoepithelial Cell Contraction: Stimulates milk ejection from alveoli into ducts

• CNS Neuromodulation: Influences social bonding, stress responses, and pain perception

Applications

1. Pharmaceutical Intermediate

• Active Pharmaceutical Ingredient (API) for oxytocic formulations

• Component in combination therapies

2. Biomedical Research

• Reproductive physiology studies

• Neuroendocrinology research (social behavior, stress responses, addiction)

• Parturition and lactation mechanism investigations

3. Veterinary Medicine

• Induction or enhancement of uterine contractions during parturition

• Treatment of postpartum retained placenta and metritis

• Treatment of agalactia in animals
