Nitrendipine tablets are suitable for the treatment of patients with essential hypertension, which can effectively reduce the blood pressure level of patients. Nitrendipine tablets belong to calcium channel blockers, can inhibit the inward flow of calcium ions to dilate the peripheral blood vessels, and thus achieve the effect of lowering blood pressure, clinically commonly used in the treatment of essential hypertension. However, because nilprednisolone is a short-acting preparation, which has a shorter time to exert its effect, and is prone to fluctuations in blood pressure, it is not used as a regular medication in clinics nowadays, and the same type of long-acting preparation can be used instead of nilprednisolone tablets, which commonly used medications include levamlodipine benzenesulphonate, felodipine extended-release tablets, and so on. During the use of Nitrendipine, patients may experience adverse reactions such as headache and facial flushing, in addition to allergies to the drug as well as severe aortic stenosis patients are prohibited from using this drug. Therefore, the drug should always be used under the supervision of a medical professional.
