Chronic pain is frequently treated with opioid analgesics, which are not without limitations in terms of their effectiveness and safety. Genetic alterations at the mu opioid receptor level may lead to a different pharmacological response between individuals. We will briefly explain chronic pain and the current limitations in its approach and management, as well as explaining the types of opioid receptors and opioids; to finally enter the field of pharmacogenetics. The objectives of this study are to check whether the scientific evidence demonstrates the implication of alterations in the OPRM1 gene on the pharmacological treatment of chronic pain, as well as other secondary objectives such as identifying possible associations between genetic polymorphisms and how these affect effectiveness and safety. To this end, it was designed a cross-sectional descriptive study that included a critical analysis of the papers retrieved through a systematic review of the articles available in the main health sciences database (MEDLINE) via PubMed. The obtained results for the intensity of chronic pain and the possible impact that the OPRM1 gene could have on this, as well as the influence that this gene exerts on pharmacological effectiveness and on the safety and adverse effects that were shown for the patients studied; finally, results were obtained for various genes involved in the pain pathways, with COMT being the most important. After examining the results, it was concluded that there is insufficient evidence of the influence of the OPRM1 rs1799971 gene on chronic pain, and that further studies are needed on effectiveness and safety. We also studied the influence of other genes, without finding conclusive results.
