Abstract

The present invention relates to a complex containing celecoxib and tramadol. The present invention is designed such that, even though two different active ingredients are prepared into a single dosage form, the release patterns of respective drugs are optimized in the expression of synergy effects, with respect to pain, of the respective drugs, through the new prescription.

Description

technical field [0001] The present invention relates to a pharmaceutical composition comprising celecoxib, known as a selective COX-2 inhibitor, and tramadol, as an opioid analgesic. Background technique [0002] [pain] [0003] According to the definition of the International Association for the Study of Pain, pain is an unpleasant sensory and emotional experience caused by actual or potential tissue damage. The causes of pain can be broadly divided into sensory conditions resulting from injury or inflammation of bodily or resistant tissues, and neuropathic conditions resulting from damage to nerves. Among them, the reported pathogenesis of the perceived condition is as follows. [0004] When tissue is damaged, the injury stimulus (stimulus) itself transmits pain by exciting myelin sheath (A-delta) and C-nociceptor (C-nociceptor). Subsequently, bradykinin, serotonin, K+, H+ and substance P are released from the damaged tissue cells and the end of the peripheral nerve. I...
