Problems solved by technology

[0004] Benidipine hydrochloride is almost insoluble in water, and the dosage form on the domestic market is only tablets, which take a long time to disintegrate, cause poor absorption in the body, low bioavailability, single administration methods, and are difficult for patients with dysphagia to take. This problem is especially prominent when you are older or when you take a large number of tablets at a time

The preparation process comprises production equipment and process for common tablets, and has the advantages of no need for special production process and equipment, simple production process and low cost.

Description

technical field [0001] The invention relates to a benidipine hydrochloride dispersible tablet and a preparation method thereof, belonging to the technical field of drug synthesis and preparation. Background technique [0002] Hypertension can be divided into primary hypertension and secondary hypertension. Essential hypertension accounts for about 90%, which is caused by dysfunction of blood pressure regulation under the influence of various factors; secondary hypertension accounts for about 5% to 10%. According to statistics from our country, the incidence of hypertension is as high as 27% among Chinese people aged 35 to 74, and the number of patients is close to 130 million, with an increase of more than 3 million every year. Hypertension can cause damage to the heart, brain, kidney and other organs, seriously threatening human health and life. Therefore, protecting the heart, brain, and kidneys and preventing heart failure, renal failure, and stroke have become importan...
