This observational retrospective cohort study was conducted to compare oral nifedipine and labetalol for emergency treatment of hypertension in preeclamptic patients. Time (minutes) and necessary doses were outlined to achieve blood pressure lower than 150/95 mmHg. In 14 patients with preeclampsia, 55 hypertensive emergencies were identified (BP >150/95). Of these emergencies, 43 were treated with oral nifedipine 10 mg (10 patients) and 12 with oral labetalol 100 mg (4 patients). To achieve a target blood pressure under 150/95, these doses were repeated as necessary every 20 min, up to a maximum of 4 doses. Oral nifedipine reduced BP more rapidly (31.30 vs. 53.50 min, p = .03). No maternal or foetal adverse events were observed and no major differences were found according to the type of delivery. Oral nifedipine is faster than and at least as safe as labetalol in pre-eclampsia hypertensive emergency treatment.

Oral antihypertensive agents and diuretics in the management of hypertension in postpartum women: a systematic review and meta-analysis.
BMJ Open
December 2024
Department of Obstetrics, University Medical Centre Utrecht, Utrecht, The Netherlands
Objective: In the puerperium, women with hypertensive disease of pregnancy remain at risk for maternal complications. The antihypertensive agent prescribed antepartum is usually continued postpartum; however, evidence regarding the most effective treatment is lacking. Therefore, we aimed to investigate which antihypertensive agent results in optimal treatment (both effectiveness and safety) of postpartum hypertension.

Article Synopsis
- The study aimed to compare the effectiveness of 60mg daily (QD) extended-release nifedipine versus 30mg twice daily (BID) for controlling blood pressure in pregnant patients before and after delivery.
- Conducted as a retrospective review at Mount Sinai Health System, the research included 237 patients with hypertensive disorders of pregnancy and evaluated the need for adjusting medication dosages.
- Results showed no significant differences in blood pressure management or emergency treatment needs between the two dosing regimens, suggesting that once-daily dosing may be more convenient for patients without compromising effectiveness.
CCN2: a potential contributor to gingival overgrowth.

Background: Fibrotic responses in the gingiva are characterized by their hyperproliferative nature instead of scar tissue formation. Clinically, these conditions appear as "gingival overgrowth" (GO), which can be of drug-induced or genetic origin. Despite surgical removal, GO can recur.

Department of Cardiology, Smidt Heart Institute, Cedars Sinai Medical Center, Los Angeles, California.
Objective: This study aimed to compare the effectiveness of oral short-acting (SA) nifedipine with intravenous (IV) labetalol for the treatment of postpartum (PP) severe hypertension.
Study Design: We conducted a retrospective cohort study of women who delivered at a tertiary care facility between January and December 2018, had not previously received antihypertensive medication, and required treatment for PP severe hypertension defined as systolic blood pressure (SBP) ≥ 160 mm Hg and/or diastolic blood pressure (DBP) ≥110 mm Hg. Exposure groups were defined by the receipt of either oral SA nifedipine or IV labetalol.
Postpartum Management of Hypertensive Disorders of Pregnancy in Six Large U.S. Hospital Systems: Descriptive Review and Identification of Clinical and Research Gaps.

October 2024
Department of Epidemiology, Boston University School of Public Health, Boston, Massachusetts.
Article Synopsis
- - Hypertensive disorders of pregnancy (HDPs) significantly affect maternal health, but there are still gaps in understanding how to best manage them postpartum across different U.S. hospital systems.
- - Six academic hospitals use similar first- and second-line medications for treating HDPs, but they vary in their approaches to monitoring blood pressure and educating patients about long-term risks.
- - The review highlights the need for future research on best practices for postpartum HDP management, particularly regarding blood pressure thresholds for treatment and addressing severe maternal morbidity and racial disparities.
