Almar is the trade name and generic name for Arolol Hydrochloride Tablets. Young patients with high low blood pressure that does not work when taken can be treated with a combination of calcium channel blockers and beta-adrenergic receptor blockers. Symptoms of high low blood pressure in young patients may be due to elevated diastolic blood pressure caused by essential hypertension. Arolol hydrochloride is mainly used in the treatment of mild or moderate essential hypertension. If the effect of lowering blood pressure is not satisfactory after taking this drug alone, it can be combined with nifedipine, propranolol and other drugs. Nifedipine can act on the calcium channels of the vascular smooth muscle cells to inhibit the calcium ions from entering the cells to reduce blood pressure. After taking propranolol, it can reduce cardiac output, inhibit the release of renin, and also inhibit the activity of the sympathetic nervous system at different levels, while increasing the synthesis of prostacyclin, to achieve the effect of lowering blood pressure. When the effect of taking Arolol Hydrochloride Tablets alone for antihypertensive treatment is not satisfactory, it is recommended to consult the cardiovascular internal medicine department in a timely manner, and standardize the treatment after the doctor comprehensively evaluates the condition.
