The aim of the present study was to determine whether guaifenesin is able to also increase analgesic activity in the non-steroid anti-inflammatory drugs ibuprofen, nimesulide and celecoxib. In addition we investigated the influence of guaifenesin on plasma levels of nimesulide.
METHODS: A model of visceral pain consisting of intraperitoneal injection of acetic acid (writhing test) was used. Levels of nimesulide in plasma were measured by HPLC. All drugs were given orally and tested in mice.
RESULTS: Guaifenesin alone did not produce any antinociceptive effect. Simultaneous administration of guaifenesin (200 mg/kg) and subanalgesic doses of ibuprofen (10 and 30 mg/kg), nimesulide (10 and 20 mg/kg) or celecoxib (1 and 5 mg/kg) resulted in a significant antinociceptive effects. The plasma levels of nimesulide were significantly higher in combination with guaifenesin at 30, 60 and 90 min after oral administration in comparison to nimesulide monotherapy.
CONCLUSION: The present results suggest that guaifenesin might enhance the analgesic activity of various non-steroidal anti-inflammatory drugs. | | Language | ENG | | Pub Type(s) | JOURNAL ARTICLE
