Which class of medication is generally used to manage hypertension during pregnancy?

Calcium channel blockers are generally considered one of the preferred classes of medication for managing hypertension during pregnancy. These medications work by inhibiting calcium from entering the smooth muscle cells of the heart and blood vessels, leading to vasodilation and a decrease in blood pressure. They are effective in treating high blood pressure and have a favorable safety profile when used during pregnancy.

While beta-blockers and diuretics may also be used, they are not first-line treatments for gestational hypertension or preeclampsia. For example, certain beta-blockers like labetalol can be safe; however, the use of other types of beta-blockers may carry risks. ACE inhibitors are contraindicated during pregnancy due to their association with adverse fetal effects, particularly during the second and third trimesters. Thus, calcium channel blockers remain a primary choice due to their effectiveness and safety in this specific patient population.
