Problems solved by technology

Because aspirin itself has a sour taste, it brings poor experience to patients, and ordinary dosage forms cannot avoid the decline in patient compliance caused by the smell of the drug
[0005] In order to reduce the stimulation of aspirin on the gastrointestinal tract, aspirin needs to be coated or made into aspirin enteric-coated tablets. For example, Chinese patent application 201310400888 discloses an aspirin enteric-coated tablet, but the enteric-coated tablet uses a large number of excipients, which cannot achieve effective The effect of masking the sour taste and anhydrous swallowing, and the preparation process is complicated, which still cannot meet the requirements of industrial production and clinical application

Abstract

The invention provides a stable aspirin taste-masking particle capable of being swallowed without water. The particle is prepared by mixing a taste-masking-layer-coated pill with a taste-modifying material, wherein the taste-masking-layer-coated pill comprises three layers of structures of a medicine core, an isolation layer and a taste-masking layer from inside to outside; and the particle is prepared by performing isolation layer coating and taste-masking layer coating on a main medicine, namely, aspirin and medicinal auxiliary materials in sequence to obtain the taste-masking-layer-coated pill, and mixing the pill with the taste-modifying material. The aspirin taste-masking particle capable of being swallowed without the water optimizes the mouth feel, well achieves the effect of masking bad smells, and improves medicine-taking compliance of patients; and the aspirin taste-masking particle can be swallowed without the water, so that the patients can swallow the particle conveniently, and the production of different specifications of aspirin taste-masking particles is facilitated.

Description

technical field [0001] The invention relates to the technical field of pharmaceutical preparations, in particular to a stable and conveniently taken anhydrous aspirin taste-masking granule for swallowing and a preparation method thereof. Background technique [0002] Aspirin is a classic drug that has been used clinically for hundreds of years. As a traditional non-steroidal anti-inflammatory drug, it is used for antipyretic and analgesic. In the treatment of arthritis, etc., it is necessary to take medicine for a long time without stopping. Therefore, it is still the most widely used antipyretic, analgesic and anti-inflammatory drug in the world, and it is also used as a standard preparation for comparing other drugs. In addition, it has an antithrombotic effect in the body, can inhibit the release reaction of platelets, inhibit platelet aggregation, and is clinically used to prevent the onset of cardiovascular diseases. But aspirin not only tastes sour, but also stimulate...
