Is this trial a fit for you?

Likely a good fit

Ideal candidates are patients admitted for delivery at 24 weeks gestation or greater who have hypertension defined as a systolic blood pressure ≥140mmHg or diastolic blood pressure ≥90mmHg.

Probably not a fit

Patients with contraindications to either Nifedipine or Labetalol, or those with certain cardiovascular conditions, may not benefit from this study.

What this trial studies

This clinical trial aims to compare the effectiveness of Labetalol and Nifedipine in managing postpartum hypertension and reducing the risk of hospital readmission and hypertensive complications. Patients who meet the inclusion criteria will be randomly assigned to receive either Labetalol or Nifedipine, with treatment escalation determined by their primary provider. The study will enroll a total of 600 patients, with 300 in each treatment arm, and monitor them for signs of hypotension and medication side effects. The goal is to achieve normotension for at least 12 hours before discharge.

Why it matters

Potential benefit: If successful, this study could provide a more effective treatment option for managing postpartum hypertension, potentially reducing hospital readmissions.

How similar studies have gone: Other studies have explored the management of postpartum hypertension, but this specific comparison of Labetalol and Nifedipine is novel.

This definition is consistent with the ACOG definition for pregnancy related HTN. Following enrollment, treatment will be escalated at discretion of primary provider with the goal of normotension.

Exclusion Criteria:

History of moderate persistent asthma, coronary artery disease, heart failure, AV heart block, pulmonary edema
