The best way to reduce hypertension is to advise patients to take oral antihypertensive drugs on time, long-term, and regularly. It is best to choose first-line, long-acting antihypertensive drugs to help bring blood pressure down more smoothly and maintain blood pressure stability. It is recommended that patients choose to apply calcium channel blockers, angiotensin-converting enzyme inhibitors, and angiotensin II receptor antagonists. In patients with tertiary hypertension it is important to combine diuretics. For patients with angina pectoris or rapid heart rate, beta-blockers can be used in combination. All of these drugs are antihypertensive drugs that have been clinically certified to have relatively few side effects, and at the same time are more effective and have some secondary prevention effects. The representative drugs of calcium channel blockers are felodipine and nifedipine. The representative drugs of angiotensin-converting enzyme inhibitors include perindopril and benazepril. The representative drugs of angiotensin II receptor antagonists are crosartan and telmisartan. Diuretics are relatively widely used, such as hydrochlorothiazide tablets, and the representative drugs of beta-blockers are bisoprolol and metoprolol.
