Abstract

The invention relates to a panax notoginseng saponins sustained-release gel and a preparation method thereof and relates to the field of medicine health care. The panax notoginseng saponins sustained-release gel comprises, by weight ratio, 56-74% of carboxymehyl chitosan, 7.4-16.6% of polyvinylpyrrolidone, 0.07-0.11% of panax notoginseng saponins and 18.4-27.7% of coss-linking agent. The medicine release rate of panax notoginseng saponins is effectively controlled, the panax notoginseng saponins utilization rate is improved, metabolism dynamics properties of the medicine in the human body are improved, too high medicine concentration in blood is avoided, and a stable plasma concentration is provided, so as to achieve the objectives of prolonging action time of the medicine in the human body and reducing dosing times; toxic and side effects of the medicine can further be reduced, and patients' compliance is improved.

Description

technical field [0001] The present invention relates to the field of medicine and health care. Background technique [0002] Cardiovascular and cerebrovascular diseases have become the number one killer of human health. They have the characteristics of "high morbidity, high disability rate, high mortality rate, high recurrence rate, and many complications", that is, "four highs and one high". Statistics show that there are currently more than 270 million patients with cardiovascular and cerebrovascular diseases in my country. With the development of society and the improvement of living standards, the Chinese people's lifestyle and diet structure have undergone tremendous changes. These lifestyles and risk factors will cause a rapid increase in the incidence of cardiovascular and cerebrovascular diseases. Medical experts at home and abroad have taken the treatment of cardiovascular and cerebrovascular diseases as an important research content. At present, western medicines f...
