Pharmacologic Options for Treatment and Prevention of Hypertensive Disorders of Pregnancy.

Hypertensive disorders affect 15% of US pregnancies, significantly contributing to maternal and neonatal morbidity. This paper explores the profound hemodynamic adaptations of pregnancy and how their failure leads to conditions like preeclampsia and gestational hypertension. Diagnosis relies on blood pressure thresholds (≥140/90 mm Hg), with management focusing on preventing severe sequelae. Labetalol and nifedipine are established as first-line treatments due to their safety and efficacy, while angiotensin-converting enzyme inhibitors and angiotensin II receptor blockers are strictly contraindicated due to fetotoxicity. Low-dose aspirin is recommended for high-risk patients. Ultimately, early recognition and evidence-based pharmacologic intervention are critical for improving obstetric outcomes.
