Název v původním jazyce

Effects of URB597, an inhibitor of fatty acid amide hydrolase (FAAH), on analgesic activity of paracetamol

Popis výsledku v původním jazyce

Paracetamol is converted to an active metabolite AM404 via fatty acid amide hydrolase (FAAH). The aim of the present study was to ascertain whether a FAAH inhibitor URB597 antagonizes paracetamol analgesic activity (and to asses by this way the role of FAAH in analgesic activity of paracetamol).METHODS: The interaction between a FAAH inhibitor URB597 and paracetamol was investigated in the writhing test in mice using an isobolographic analysis. RESULTS: URB597 or paracetamol alone and in combinations produced dose-dependent antinociceptive effects. ED50 values were estimated for the individual drugs and an isobologram was constructed. The observed ED50 value for the URB57-paracetamol combination was 0.097 (0.062-0.247) mg/kg. This value did not differsignificantly from the theoretical additive ED50 value for the URB597-paracetamol combination which was 0.108 (0.059-0.198) mg/kg. Thus, inhibition of FAAH by URB597 was not followed by the lack of analgesic activity in paracetamol. CONCL
