According to different mechanisms of action, the most common antihypertensive drugs can be divided into five types. Which drug is good depends on the antihypertensive effect, the size of side effects and whether there is organ protection for the heart, brain and kidneys. A good antihypertensive drug should meet the requirements of good antihypertensive effect, low side effects and organ protection for the heart, brain and kidneys. There are many different kinds of drugs that can be used to treat hypertension. The most common antihypertensive drugs are: calcium antagonists, angiotensin-converting enzyme inhibitors, angiotensin receptor antagonists, diuretics, and beta-blockers. These drugs have different mechanisms of action and can be used for the initial and maintenance treatment of hypertension, but each has its own characteristics and indications. There are four criteria for ideal antihypertensive drugs: 1, good antihypertensive efficacy, certain cardiovascular protection; 2, long-acting preparations, 24-hour smooth antihypertensive, avoid blood pressure fluctuations; and once a day, easy to take; 3, small side effects, good safety, good tolerability; 4, reasonable price. The choice of medication often varies from person to person. For example, if you have diabetes, your doctor may prescribe a Prilosec-type drug instead of a diuretic because diuretics sometimes affect blood sugar levels. If your blood pressure is very high, your doctor may prescribe a combination of two or more medications at the same time to achieve a reduction in blood pressure. Your doctor will monitor your blood pressure regularly for several months after you start your antihypertensive medication to make sure your blood pressure is meeting your treatment goals. The so-called good drugs are not only effective in lowering blood pressure with few side effects, but also have a protective effect on the heart, brain, kidneys and other organs. So choose your antihypertensive medication, whichever is better, and start with a good one.
