Oral labetalol versus oral nifedipine for the management of postpartum hypertension a randomized control trial: Labetolol v/s nifedipine for Postpatum H/T: A RCT

Objective: To compare the efficacy of oral Labetalol versus oral Nifedipine for the treatment of postpartum hypertension.

Methods: A prospective randomized controlled trial with parallel assignment was conducted in the department of Obstetrics and Gynecology, Dow University of Health Sciences Karachi, Pakistan, 124 patients with post partum hypertension were selected and randomized into two groups with 62 patients receiving Labetalol and 62 receiving long acting nifedipine. Initial blood pressures were recorded, and the respective drug was administered. Dose adjustments were performed in the initial 24 hours. The outcome was measured in the form of drug efficacy by lowering of systolic blood pressure less than 140mm of Hg and diastolic less than 90mm of Hg up to 48 hours after starting treatment. Data was entered and analyzed through SPSS version 20.

Results: Our study randomized 62 women to oral labetalol and 62 women to oral long acting nifedipine. The time required to achieve blood pressure control was 35.6±2.8 hours in labetalol group and 30.4±1.9 hours in nifedipine group (p=0.04).length of hospital stay, need of additional antihypertensive medications were same in both groups. Minor side effects were observed more in nifedipine group.

Conclusion: We conclude that both oral labetalol and oral long acting nifedipine are effective and well tolerated interventions for the management of post-partum hypertension. However we found Nifidipine more effective in the management of postpartum hypertension.
