Preterm Labor with Side Effects: Compare the Effectiveness of Magnesium Sulfate (MgSO4) with Isoxsuprine

Background: In India, 25% of pregnancies develop preterm labor (PTL), resulting in 10 to 69% cases of preterm birth. Medical intervention to stop labor, reduce infection rate, and avoid infant respiratory distress has been the subject of studies for a long time. PTL patients usually get tocolytics, corticosteroids, antibiotics, and other clinically symptomatic and supportive therapy to accomplish this goal. Studies further showed that these tocolytic drugs lower intracellular calcium bioavailability via biochemical pathways, hindering the interaction of actin-myosin. Due to the poor success rate of labor arrest, researchers concluded from their studies that widespread adoption of medical management for PTL has been hampered. The high rate of major side effects of tocolytic drugs, particularly beta-mimetic ones, exacerbated this. We know of no clinical evidence on PTL management in India. Objective: The effectiveness and maternal side effects of MgSO4 and isoxsuprine in PTL arrest. Methods: In our study, we included a total of 82 pregnant women who had PTL discomfort and were admitted to the labor department. Both groups were randomly assigned patients. “Group 1 patients received isoxsuprine hydrochloride, whereas group 2 patients received MgSO4”. After that, a comprehensive clinical examination included vital signs, general, systemic, external genitalia, and PV (per vaginal) results. Investigations include CBC, BT, CT, urine full examination, ABO, RH group, serum electrolytes, RBS, vaginal swab, and Renal function test (RFT). Result: Significant difference (p <0.05) indicated that MgSO4 was more effective. Conclusion: MgSO4 can be used as a tocolytic agent in PTL as it shows better tolerance capacity when compared to isoxsuprine.
