Hypertension is divided into two categories: primary and secondary hypertension, and primary hypertension is also known as hypertension. According to statistics, it accounts for about 95% of the cases, and its causes are closely related to long-term mental stress, excessive salt intake, obesity, smoking, genetics and other factors. Secondary hypertension common causes: such as pheochromocytoma, primary aldosteronism, renal artery stenosis, glomerulonephritis, cortisolism, etc.. This type of hypertension can be cured if the cause is eliminated. Primary hypertension cannot be cured and requires long-term medication. At present, there are six types of drugs for the treatment of hypertension: (1) diuretics: such as dihydroketorolac, aminoglutethimide; (2) beta-blockers: such as aminoglutethimide, betalactam; (3) calcium antagonists: such as our Fodar, Bactrim, Boydin, lacidipine, amlodipine, etc.; (4) angiotensin-converting enzyme inhibitors, such as: captopril, enalapril, benazepril, fosinopril, lenopril, etc.; (4) angiotensin-converting enzyme inhibitors, such as: captopril, enalapril, benazepril, fosinopril, lenopril (5) alpha-blockers: such as prazosin, doxazosin, etc.; (6) angiotensin II receptor antagonists: cloxacin, valsartan, irbesartan, candesartan, etc. The above five categories of drugs are known as the first-line antihypertensive drugs today. Depending on the specific conditions of the body, 1 or 2 drugs are usually sufficient. If the effect of lowering blood pressure is not good, you can also apply a variety of drugs in combination, when the blood pressure is reduced to a normal level, you need to gradually reduce the amount, the best to maintain blood pressure below 135/83mmHg. According to current statistics, the incidence of cardiovascular disease is lowest when blood pressure is maintained below 135/83mmHg, and it is called ideal blood pressure if blood pressure is maintained below 120/80mmHg. After the blood pressure is reduced to normal level does not mean that the hypertension has been cured, and it is still necessary to continue to take small doses of medication for maintenance treatment. After 2-3 months of low-dose maintenance therapy, blood pressure remains at normal levels, and can be considered for discontinuation of the drug for observation. However, the blood pressure should be measured once a day, and if there is a tendency for the blood pressure to rise, the treatment should be continued. It is worth noting that the drug should not be stopped suddenly during the treatment process, or intermittent medication treatment, which will make the blood pressure rebound phenomenon and blood pressure instability, easily causing damage to the heart, brain, kidneys and other organs, such as high blood pressure can be complicated by cerebral hemorrhage and other serious adverse consequences.
