The aim of the study – to analyze the literature data on the properties of oxytocin, a drug widely used in obstetric and gynecological practice. Its role as a neurotransmitter has been demonstrated, exerting a significant influence on almost all organs and systems, as well as on social, behavioral, and mental responses of individuals. In obstetric practice, oxytocin is prescribed according to established protocols; however, many details contradict the information provided in the drug instructions. Both clinical practice and literature data indicate the necessity of further research regarding minimal effective doses, routes of administration, and its effects on the mother and fetus.
Conclusions. The need to introduce the issue of finding optimal oxytocin regimens that will minimize the risks of hyperstimulation while ensuring the effectiveness of therapy.
