Codeine did not increase analgesic efficacy of coxibs in contrast to that of paracetamol or ibuprofen: isobolographic analysis in mice

Popis výsledku v původním jazyce

There is good evidence that opioids can potentiate analgesic activity of some older non-opioid analgesics (such as paracetamol or ibuprofen) but it is not known whether this also holds true for newer non-opioid analgesics that selectively inhibit cyclooxygenase 2 (coxibs). This study was undertaken to determine the nature of the interaction between codeine and celecoxib or etoricoxib in peritoneal irritation-induced visceral pain in mice. For comparison, interactions of codeine with paracetamol and ibuprofen were also tested using the same method. A small volume of a weak acetic acid (0.6%) was injected into the peritoneal cavity and the number of writhes (contractions of abdominal muscles) was counted. All drugs were given orally. Their interaction was characterized using isobolographic analysis. Codeine, etoricoxib, celecoxib, ibuprofen and paracetamol all independently produced dose-dependent suppression of writhing. The isobolographic analysis carried out using equipotent dose rati
