Problems solved by technology

The current medicines for the treatment of this disease mainly use ginkgo ketone ester as the main component, and drop pills are used to treat cardiovascular and cerebrovascular diseases; however, the disintegration time of the existing ginkgo ketone ester drop pills in the gastrointestinal tract is too long, generally 15 to 18 minutes , for the pain caused by the urgent need to solve the disease, it seems that it takes a long time for the patient to endure
[0004] The patent applications CN200610113450.7 and CN201010112227.7 proposed by the applicant reported ginkgo ketone ester drop pill preparations, but the drop pills made by it are not satisfactory in terms of dissolution rate, disintegration time limit, and appearance, and cannot solve the problem all the time. patient pain problem

Abstract

The invention discloses a ginkgo ketone ester dripping pill, which comprises a ginkgo ketone ester and a medicinal matrix, the weight percentage of which is 10%-18%: 82%-90%; the medicinal matrix is ​​composed of polyethylene glycol 4000 , polyethylene glycol 6000 and polyethylene glycol 8000 are composed of 3-5:1-1.3:0.4-0.7 by weight ratio; the preparation method of the dropping pill is also disclosed. The present invention is composed of ginkgo ketone ester and medicinal matrix according to a specific ratio, and the medicinal matrix is ​​a mixture of three polyethylene glycols with different molecular weights, so that the disintegration speed of the ginkgo ketone ester dripping pill is fast, and the disintegration time is 6-10 minutes; make the drug effect act on the human body in a short time, and relieve the patient's pain.

Description

technical field [0001] The invention relates to a drop pill preparation and a preparation method thereof, in particular to a ginkgo ketone ester drop pill and a preparation method thereof. Background technique [0002] Dropping pills refer to the preparations made by solid or liquid medicine and matrix heated, melted and mixed, then dropped into immiscible condensate, shrinking and condensing; matrix generally includes water-soluble matrix and non-water-soluble matrix, commonly used are Polyethylene glycol 6000, gelatin, stearic acid, etc.; the condensate must be safe and harmless, and liquid paraffin, vegetable oil, methyl silicone oil, and water are commonly used. [0003] Cardiovascular and cerebrovascular diseases are characterized by high morbidity, high mortality and high disability, and are the number one killer of human health. The current medicines for the treatment of this disease mainly use ginkgo ketone ester as the main component, and drop pills are used to tre...
