PHARMACOLOGY OF DRUGS REGULATING UTERINE CONTRACTIONS

Abstract

This paper examines the pharmacological agents used in the management of postpartum hemorrhage and their clinical significance in obstetric practice. Postpartum hemorrhage is a major cause of maternal morbidity and mortality worldwide and requires immediate medical intervention. The study describes the causes of postpartum hemorrhage, commonly summarized as the “4 Ts” (Tone, Trauma, Tissue, Thrombin), and focuses on pharmacological treatment options. It analyzes uterotonic drugs such as oxytocin, methylergometrine, prostaglandin analogues, and carbetocin, as well as antifibrinolytic agents like tranexamic acid. The mechanisms of action, indications, and importance of timely administration are highlighted. Special attention is given to the role of nurses in early recognition of bleeding, drug administration, patient monitoring, and emergency care. Understanding pharmacological management of postpartum hemorrhage is essential for improving maternal outcomes and reducing preventable maternal deaths.
