Abstract

The invention discloses an uncaria sustained-release tablet and a preparation method thereof; the uncaria sustained-release tablet comprises the following components in parts by weight: 1 to 30 parts of rhynchophylline or uncaria alkaloid, 10 to 70 parts of sustained-release auxiliary materials and other auxiliary materials: 0.2 to 5 parts of pore-foaming agent, 10 to 45 parts of filler, 0.5 to 20 parts of adhesive, 5 to 15 parts of wetting agent, 0.1 to 2 parts of lubricant, 0 to 5 parts of solubilizer, 0 to 10 parts of emulsifier, 0 to 25 parts of membrane material, 0 to 15 parts of opacifying agent and 0 to 25 parts of solvent. The invention slowly releases the medicine through a sustained-release technology, can effectively reduce the fluctuation of plasma concentration, prevents the 'peak and valley' phenomenon of common preparation caused by frequency medication, improves the utilization rate of the medicine, reduces the medical expenses, reduces the direct stimulation of the medicine to the gastrointestinal tract so as to reduce the side effect, so that a patient is more tolerant, thereby facilitating long-termed curing and more facilitating the curing of hypertension.

Description

technical field [0001] The invention relates to an Uncaria sustained-release tablet and a preparation method thereof, belonging to the technical field of medicines. Background technique [0002] The new guidelines for the treatment of hypertension released by the World Health Organization to the world believe that with the changes in human life style and living environment, the proportion of hypertensive patients in the total population has become higher and higher, and heart disease caused or induced by hypertension Diseases of the brain, brain and kidney have become the number one killer that endangers human life and health. Hypertension is the most important risk factor leading to major diseases of human death such as coronary heart disease and cerebrovascular disease. The morbidity and mortality of cardiovascular and cerebrovascular diseases are closely related to the blood pressure level of patients. Therefore, all countries in the world attach great importance to the p...
