Abstract

The invention discloses a dexibuprofen particle which is mainly prepared from the following raw materials in parts by weight: 1-10 parts of dexibuprofen, 1-6 parts of sodium carbonate, 1-35 parts of sucrose, 0.1-0.8 part of aspartame and 3-12 parts of ethanol. The invention also discloses a preparation method of the dexibuprofen particle, which comprises the following steps of: sieving each raw material, and then, fully mixing the raw materials uniformly; granulating; and drying at high temperature, and then, refining to obtain the dexibuprofen particle. The dexibuprofen particle of the invention can endure high-temperature drying, has qualified indexes of microbial limit, solubility and the like and has stable and controllable quality; in addition, the preparation method is simple to operate has short production cycle and low cost, and is suitable for industrialized production.

Description

technical field [0001] The invention relates to the field of pharmaceutical preparations, in particular to a dextrobuprofen granule and a preparation method thereof. Background technique [0002] Ibuprofen is a propionic acid non-steroidal anti-inflammatory drug with analgesic, anti-inflammatory and antipyretic effects. Congestion and swelling of the tissues in the body can reduce the sensitivity of peripheral nerve pain. It acts as an antipyretic through the hypothalamic thermoregulatory center. [0003] Although ibuprofen is a commonly used non-steroidal anti-inflammatory drug at present, its wide application is affected due to reasons such as large oral dose, poor taste and gastrointestinal irritation. In recent years, there have been many clinical adverse reactions of ibuprofen, such as anaphylaxis, anaphylactic shock, lower extremity edema, nausea, vomiting, indigestion and so on. Clinically, the application of mixed ibuprofen instead of ibuprofen has also been adopte...
