[0008] Starch is the basic excipient of oral solid preparations. It is formed by the polymerization of glucose molecules. It is often used as a binder, diluent and disintegrating agent in tablets. It is cheap and easy to obtain, and is safe for the human body. However, starch is used alone as an excipient There is no report on the production of aspirin freeze-dried tablets by freeze-drying process

Abstract
The invention provides aspirin composition freeze-dried tablets and a preparation method thereof, and relates to the technical field of medicine and medicine production. The aspirin composition freeze-dried tablets comprise aspirin, starch and sucrose, wherein starch and sucrose are used as accessories. Ordinary corn starch is treated by a heating process, so that the bonding and disintegration effects of starch in the tablets can be improved, and the forming property of the tablets can be improved; only starch and sucrose are required to be used as the accessories of the aspirin composition freeze-dried tablets. A two-cooling two-heating freeze-drying process is adopted for the aspirin composition freeze-dried tablets, and by twice cooling and twice heating, better forming property of the tablets can be achieved, and the dissolubility of the tablets is improved, so that the bioavailability of the tablets is improved. According to the tablets, the defects of ordinary aspirin tablets are overcome, the sort and using amounts of the accessories in the aspirin tablets are reduced, the tablets are high in dissolubility and bioavailability, and the curative effects and safety of clinical mediation are ensured.
Description
technical field [0001] The invention relates to the technical field of medicine and medicine production, in particular to a freeze-dried tablet of aspirin composition and a preparation method thereof. Background technique [0002] Aspirin, also known as acetylsalicylic acid, is an antipyretic and analgesic with a long history, which was born on March 6, 1899. It is used to treat colds, fever, headache, toothache, arthralgia, rheumatism, and can also inhibit platelet aggregation. It can also be used to prevent and treat ischemic heart disease, angina pectoris, cardiopulmonary infarction, and cerebral thrombosis. It can also increase the germination rate of plants. , It is also effective in angioplasty and bypass grafting. [0003] structural formula [0004] Molecular weight: 180.16 [0005] Ordinary aspirin tablets contain many types and quantities of excipients. Generally, fillers, lubricants, disintegrants, binders, flavoring agents, etc. are used. , the dissolution ...
