Which medication is commonly used for managing chronic hypertension in pregnancy?

Labetalol is commonly used for managing chronic hypertension in pregnancy due to its safety profile and efficacy. It is a mixed alpha and beta-adrenergic antagonist, which makes it effective in lowering blood pressure while minimizing risks to both the mother and fetus. Labetalol is well-tolerated during pregnancy and does not have the same adverse effects as some other antihypertensive medications, making it a preferred choice.

In contrast, while atenolol can lower blood pressure, it is not as commonly used as labetalol in pregnant patients because some studies suggest potential risks to the fetus, such as growth restriction. Hydrochlorothiazide, a diuretic, can lead to dehydration and electrolyte imbalances, which are undesirable in pregnancy. Losartan, an angiotensin receptor blocker, is contraindicated in pregnancy, especially in the second and third trimesters, due to its association with fetal renal impairment and other serious complications. Thus, labetalol stands out as the most appropriate and safest option for managing chronic hypertension in pregnant individuals.
