Problems solved by technology

[0003] But, because the ibuprofen in this composition is almost insoluble in water, pharmacokinetic parameter T max (The time to reach the maximum blood concentration) is 1.5-2h. Like other oral NSAIDs (non-steroidal anti-inflammatory drugs), the onset of action is relatively slow, and it has a certain stimulating effect on the gastrointestinal tract.

Abstract

A composite medicine of ibuprofen, arginine and codeine is proportionally prepared from ibuprofen, arginine and codeine or its pharmacologically acceptable salt.It has high water solubility and less stimulation to stomach and intestine.

Description

(1) Technical field [0001] The invention relates to a compound preparation containing ibuprofen arginine and codeine or a pharmaceutically acceptable salt composition thereof. (2) Background technology [0002] Codeine or its pharmaceutically acceptable salts (such as codeine phosphate) are considered by those skilled in the art to directly inhibit the cough center of the brain and have a strong antitussive effect. Ibuprofen, a non-steroidal anti-inflammatory drug, is also known to have antipyretic, anti-inflammatory, and analgesic effects. Therefore, the oral composition containing both ibuprofen and codeine or a pharmaceutically acceptable salt thereof is suitable for severe dry cough and irritating cough caused by various reasons, especially for severe dry cough accompanied by chest pain. Its analgesic effect can be used for moderate pain, such as postoperative pain and moderate cancer pain. [0003] But, because the ibuprofen in this composition is almost insoluble in ...
