When blood pressure exceeds 140/90 mmHg even after general treatment to improve lifestyle, medication is given. The goal of hypertension treatment is to reduce the overall risk of cardiovascular, renal, vascular complications and death. Patients whose blood pressure exceeds 140/90 mmHg and/or the target level despite lifestyle improvements should be treated with medications to lower their blood pressure. Five types of antihypertensive medications are commonly used, including diuretics (e.g., amiloride, aminopterin, etc.), calcium antagonists (e.g., amlodipine, felodipine, etc.), beta blockers (e.g., carvedilol, metoprolol, etc.), angiotensin receptor antagonists (e.g., chlosartan, valsartan, etc.), and angiotensin-converting enzyme inhibitors (e.g., perindopril, fosinopril, etc.). Hypertension refers to the phenomenon in which flowing blood exerts a consistently higher than normal pressure on the walls of blood vessels. Typical symptoms include headaches, arrhythmias and palpitations and tinnitus. The causes of hypertension are not yet known and may be related to a variety of factors such as heredity, age and poor lifestyle. It is recommended that patients with hypertension should actively cooperate with their doctors for treatment, and medications should be used under doctor’s guidance, not without authorization, to avoid delaying the condition. If you experience symptoms such as rapid heartbeat during the use of medication, you should go to the hospital in a timely manner.
