Key clinical point: A dose of 30 mg oral extended-release nifedipine (ER-nifedipine) every 24 hours until delivery effectively reduced the receipt of treatment for acute severe hypertension in individuals with preeclampsia with severe features.
Major finding: A significantly lower proportion of individuals who received 30 mg ER-nifedipine vs placebo required ≥1 dose of acute hypertension therapy for severe blood pressure that sustained for ≥10 minutes (34.0% vs 55.1%; relative risk 0.62; 95% CI 0.39-0.97). ER-nifedipine vs placebo use led to numerically lower cesarean deliveries (20.8% vs 34.7%) and neonatal intensive care unit admissions (29.1% vs 47.1%).
Study details: Findings are from a phase 4 trial including 110 individuals with singleton or twin gestation undergoing labor induction for preeclampsia with severe features who were randomly assigned to receive 30 mg oral ER-nifedipine or placebo every 24 hours until delivery.
Disclosures: This study was funded by The Ohio State University Department of Obstetrics and Gynecology. No conflicts of interest were declared.
