The pregnancy preparation period is the stage of preparation for pregnancy. For women with high blood pressure, it is very important to choose appropriate antihypertensive drugs. While preparing for pregnancy, some antihypertensive drugs are safe to use, but some are not recommended or prohibited. Below are the antihypertensive drugs suitable for taking during pregnancy preparation and the corresponding answers.
1. Calcium channel blockers: These drugs can help relax blood vessels and lower blood pressure. When preparing for pregnancy, you can choose some non-dihydropyridine calcium channel blockers, such as verapamil. These medications are relatively safe and pose low risks to pregnancy.
2. Alpha-blockers: These drugs can reduce the load on the heart and lower blood pressure. When trying to conceive, some selective alpha-1 blockers, such as labetalol, are available. These drugs are relatively safe for pregnant women and fetuses.
3. Methyldopa: This is an antihypertensive drug that can reduce blood pressure by reducing renin secretion. Methyldopa can be used during pregnancy, but the dose needs to be closely monitored to avoid hypotension.
4. Alpha-2 receptor agonists: These drugs can lower blood pressure through the action of the central nervous system. When preparing for pregnancy, you can choose some selective alpha-2 receptor agonists, such as milnapril. These drugs are relatively safe for pregnant women and fetuses.
5. Beta-blockers: These drugs can reduce cardiac contractility and heart rate, thereby reducing cardiac load and lowering blood pressure. Selective beta-1 blockers, such as propranolol, are available during pregnancy. These drugs are relatively safe for pregnant women and fetuses.
It should be noted that the following antihypertensive drugs need to be avoided during pregnancy preparation:
1. ACE inhibitors and ARBs: These drugs can lower blood pressure but may have adverse effects on the fetus during pregnancy, especially In the first trimester. Therefore, these medications should be avoided during preparation and pregnancy.
2. Diuretics: Diuretics can help eliminate excess water and salt, thereby lowering blood pressure. However, diuretics should be avoided during preparation for pregnancy as they may cause volume depletion, negatively affecting the health of the mother and fetus.
3. Nonsteroidal anti-inflammatory drugs (NSAIDs): These drugs can relieve pain and inflammation, but should be avoided during pregnancy. NSAIDs may interfere with the ovulation and fertilization processes, adversely affecting the health of the mother and fetus.
In summary, antihypertensive drugs suitable for pregnancy include calcium channel blockers, α-Beta blockers, methyldopa, alpha-2 agonists, and beta-blockers. Antihypertensive medications to avoid include ACE inhibitors, ARBs, diuretics, and nonsteroidal anti-inflammatory drugs. You should seek medical advice when selecting and using antihypertensive medications to ensure safety and minimize risks to pregnancy. Remember, maintaining a healthy lifestyle including a balanced diet, moderate exercise and reducing stress while trying to conceive is also important to control blood pressure.
