Problems solved by technology

In addition, since the lower limit of D-borneol content in natural borneol is 96%, it still contains a certain amount of impurities, which may affect the safety of medication. Therefore, people have purified natural borneol, and currently there are commercially available products with a purity of ≥98%. (+)-2-borneol
[0015] The Pharmacopoeia stipulates that the daily dose of borneol is 150-300 mg per day. Taking large doses of borneol may cause gastrointestinal adverse reactions such as heartburn, nausea, abdominal pain, and vomiting.

Abstract

A pharmaceutical composition comprising butylphthalide and borneol is disclosed. The pharmaceutical composition has synergistic effects on treating cerebrovascular diseases especially ischemic cerebrovascular diseases, and is capable of obviously enhancing treating effects of the butylphthalide, reducing the effective dose of the butylphthalide, and reducing the using amount. Untoward effects of the pharmaceutical composition during long-term application can be reduced.

Description

technical field [0001] The invention relates to a pharmaceutical composition containing butylphthalide and borneol and its application in the preparation of medicaments for treating cerebrovascular diseases. Background technique [0002] Cerebrovascular disease (CVD) is a brain lesion caused by cerebrovascular abnormalities. Stroke generally refers to acute cerebrovascular disease. According to the survey data of 17 countries and regions by the World Health Organization, the incidence of cerebrovascular disease fluctuates between 15 and 287 / 100,000, and the regional distribution is different. The average incidence of cerebrovascular disease in my country is about 1.30 / 1.1 million, higher than that in Europe and the United States, and close to Japan. Data studies from all over the world show that the incidence of cerebrovascular disease increases with age. At present, China is facing the challenge of rapid aging. Cerebrovascular disease is the second major cause of serious ...
