Simple hypertension (blood pressure greater than 140/90 mmHg) can be treated with antihypertensive therapy either singly or in combination with ACEIs (e.g., enalapril), ARBs (e.g., irbesartan tablets), calcium channel blockers (e.g., nifedipine tablets), diuretics (e.g., hydrochlorothiazide), and beta-blockers (e.g., metoprolol). Specifically as follows: 1.ACEI. Angiotensin-converting enzyme (ACE) inhibitors lower blood pressure by dilating blood vessels. Examples: Enalapril, Perindopril, etc. 2. Angiotensin 2 receptor blockers (ARBs). ARBs work in a similar way to ACE inhibitors. If ACE inhibitors cause troublesome side effects such as dry cough, it is often recommended to switch to ARBs such as Irbesartan and Valsartan. 3. Calcium channel blockers. Calcium channel blockers lower blood pressure by dilating blood vessels. For example: amlodipine, felodipine, etc. 4. Diuretics. Diuretics work by eliminating excess water and salt from the body through urination. E.g. hydrochlorothiazide. 5. beta-blockers. beta-blockers can lower blood pressure by reducing the contractility of the heart muscle and lowering sympathetic nerve excitability. For example, bisoprolol. The above antihypertensive drugs can be used jointly or singly, each person’s antihypertensive program is different, taking antihypertensive drugs in the process of the need to adjust the medication at any time according to the value of the blood pressure, the specific should be taken under the guidance of clinicians.
