Which medication is typically used to manage pregnancy-induced hypertension?

Calcium channel blockers are often used to manage pregnancy-induced hypertension because they effectively lower blood pressure by inhibiting the entry of calcium into cardiac and smooth muscle cells. This results in relaxation of the blood vessels, reducing vascular resistance and leading to decreased blood pressure. Medications such as nifedipine are commonly prescribed for this purpose, as they are considered relatively safe for use during pregnancy.

In contrast, beta-blockers can be used but are not first-line due to potential side effects for the fetus, especially with certain types. ACE inhibitors are contraindicated during pregnancy as they can lead to serious fetal complications, particularly in the second and third trimesters. Diuretics can be used for hypertension but are generally avoided in pregnancy unless specifically indicated, as they can lead to decreased plasma volume and other complications that might affect the mother and fetus. Therefore, calcium channel blockers stand out as a suitable choice for managing pregnancy-induced hypertension.
