Abstract

The invention discloses a composite drug stent and a preparation method thereof, the composite drug stent comprises a stent body, a covering film and a composite drug, the covering film is arranged on the inner side of the stent body, the first composite drug is arranged on the stent body, and the first composite drug comprises aspirin, propranolol hydrochloride and atorvastatin. According to the technical scheme, the covering film is arranged on the inner side of the stent body, and the medicine is arranged on the stent body, so that the medicine is slowly released from the stent body to treat the blood vessel wall, and the situation that after the covered stent is placed, the blood vessel wall and blood are separated, the medicine cannot reach the separated blood vessel wall, the blood vessel healing speed is reduced, and the blood vessel healing effect is affected is avoided. Vascularization and the like are solved.

Description

technical field [0001] The invention relates to the technical field of medical equipment, in particular to a composite drug stent and a preparation method thereof. Background technique [0002] Aspirin [Aspirin, 2-(acetoxy) benzoic acid, also known as acetylsalicylic acid] is a white crystal or crystalline powder, odorless or slightly acetic acid odor, slightly soluble in water, easily soluble in ethanol, can be Soluble in ether and chloroform, the aqueous solution is acidic. This product is a derivative of salicylic acid. After nearly a hundred years of clinical application, it has been proved that it has a good effect on relieving mild or moderate pain, such as toothache, headache, neuralgia, muscle pain and dysmenorrhea. It is also used for colds, flu, etc. Relieving fever of febrile diseases, treating rheumatism and so on. In recent years, it has been found that aspirin has an inhibitory effect on platelet aggregation and can prevent thrombosis. It is clinically used t...
