Pharmacologic approaches for the management of systemic hypertension in pregnancy

Hypertension in pregnancy includes a group of distinct disorders that require special consideration in both prevention and pharmacologic treatment. In recent years, there have been few advances regarding the pathophysiology and prevention of preeclampsia, or in recommendations for first-line drug therapy of the hypertensive complications of preeclampsia. Similarly, the recommendations for pharmacologic treatment of women with chronic hypertension antedating pregnancy have changed little, primarily because first-line medications have the advantage of having been the subjects of extensive research experience. Recent clinical trials have demonstrated the efficacy and safety of various second-line drugs for treating hypertensive disorders of pregnancy; whether these therapies can eventually replace the standard recommended medications will require more extensive long-term investigation.
