Abstract

The invention discloses an ibuprofen granule, which is prepared from the following raw materials in parts by weight: 1 part of ibuprofen, 1-100 parts of filler, 1-20 parts of adhesive, 0.2-10 parts of thickener, Flavor agent 0.1~10 parts. The granule dissolves rapidly in water, forms a clear and transparent solution with good taste, is convenient to take, has low related substances and high bioavailability. The invention also discloses a preparation method of the ibuprofen granule, the preparation method is simple to operate, does not need any special equipment, and is suitable for industrial production.

Description

technical field [0001] The invention relates to the field of pharmaceutical preparations, in particular to ibuprofen granules and a preparation method thereof. Background technique [0002] Ibuprofen, chemical name: 2-methyl-4-(2-methylpropyl) phenylacetic acid, IUPAC name: 2-(4-isobutylphenyl) propanoic acid, CAS No.15687-27-1, molecular formula C 13 h 18 o 2 , with a molecular weight of 206.28, is a non-steroidal anti-inflammatory drug (NSAID). It is the first profen drug used clinically and is still widely used in the world. It is recognized as one of the safest drugs in non-steroidal anti-inflammatory drugs. 1. It has analgesic, anti-inflammatory and antipyretic effects. Its mechanism of action is to reduce the synthesis of prostaglandins by inhibiting cyclooxygenase, thereby reducing tissue congestion and swelling caused by prostaglandins, and reducing the sensitivity of peripheral nerve pain. Sex, and play an antipyretic effect through the hypothalamic thermoregula...
