Which class of medications is used to treat hypertension in pregnancy?

Calcium channel blockers are indeed a primary choice for treating hypertension during pregnancy. These medications work by relaxing the blood vessels, which helps to lower blood pressure and increase blood flow to the uterus without causing significant harm to the fetus. Commonly used calcium channel blockers in this context include nifedipine and amlodipine, which are often preferred due to their safety profile and effectiveness in managing elevated blood pressure in pregnant individuals.

ACE inhibitors and beta-blockers are generally not recommended for use in pregnancy. ACE inhibitors, for instance, can have teratogenic effects and may lead to complications like renal impairment and growth restriction in the unborn baby, especially in the second and third trimesters. Although some beta-blockers can be used cautiously in pregnancy, they are not always the first line due to potential side effects such as fetal growth restriction and neonatal bradycardia.

Thus, calcium channel blockers stand out as the most appropriate and widely accepted class for managing hypertension in pregnancy, making this choice the correct one.
