COMPARATIVE STUDY OF NIFEPIDINE AND ISOXSUPRINE IN SUPPRESSION OF PRETERM LABOUR IN THIRD TRIMESTER
Background: A prospective study was conducted to compare the efficacy of nifedipine against isoxsuprine in preventing preterm labour in third trimester and also to evaluate maternal side effects and neonatal outcome. Methods: This prospective comparative study was conducted at JLNMCH, Bhagalpur, Bihar. 75 antenatal women with gestational age between 28 to 36 weeks wereselected who fulfilled the inclusion criteria for the study, were given nifedipine and were monitored throughout thecourse of treatment. Results: Groups were compared with mean prolongation of delivery, side effects, neonatal outcome, parity, cervicaleffacements. Nifedipine was twice more effective than isoxsuprine hydrochloride as a uterine tocolytic agent whileside effects were comparable with fewer side effects in nifedipine group. Neonatal outcome was better with nifedipinein comparison to isoxsuprine. Conclusions: There is a high incidence of preterm labour in India. The present study found that nifedipine has bettertocolytic efficacy, less side effects and better tolerability as compared to isoxsuprine in third trimester.
