In the context of managing hypertension during pregnancy, Methyldopa and Labetalol are both well-established options. Methyldopa is a centrally acting alpha-2 adrenergic agonist that has a long history of use in pregnancy and is considered safe for both the mother and the fetus. It works by decreasing peripheral vascular resistance, which leads to lower blood pressure.

Labetalol, a mixed alpha and beta-adrenergic blocker, is also frequently utilized because it effectively lowers blood pressure while minimizing adverse effects on fetal heart rate. The use of these medications is supported by clinical guidelines and extensive research indicating their safety and efficacy in pregnant individuals.

Other options listed, such as Aspirin and Ibuprofen, while sometimes used during pregnancy for specific indications, do not primarily serve as hypertension treatments. Aspirin may be recommended for certain high-risk patients to prevent preeclampsia, but it does not directly manage hypertension. Ibuprofen, a non-steroidal anti-inflammatory drug (NSAID), is typically avoided in pregnancy, particularly in the third trimester, due to potential risks to both the mother and fetus.

Angiotensin Receptor Blockers are contraindicated in pregnancy due to their association with fetal harm, especially in the second
