Research Abstract

In association studies targeting genetic polymorphisms identified in brain-type GIRK1-GIRK3 genes, significant associations were found between the GIRK3 C1339T, C1781T and C1817T polymorphisms and requirements of postoperative 24-h opioid analgesics after major open abdominal surgery or painful orofacial cosmetic surgery. In particular, there were significant associations in the C1781T and C1817T between analgesic requirements and mRNA expressions, suggesting that the GIRK3 mRNA expression could affect the analgesic effects of opioids.
