Abstract: Opioid type of analgesics open A TP sensitive potassium channel at the cellular level to produce antinociceptive response. These channels have also been shown to modulate insulin secretion by the pancreas.7-hydroxy flavone, an antinociceptive agent shown to act through opioid pathways was investigated for its effect on glycaemic state and associated algesic state. The involvement of ATP sensitive potassium channel in the action was examined by using glybenclamide. The result reveal that 7-HF per se did not elicit any significant change in the glycaemic state simultaneously eliciting antinociceptive response as tested by acetic acid induced abdominal constriction assay procedure. Glibenclamide treatment attenuated the antinociceptive effect of 7-HF and while maintained its hypoglycaemic response. The present finding suggest that 7-HF induces antinociception like morphine, utilise A TP sensitive potassium channel at the cellular level and do not suggest a cause-effect relationship between the changes in the glycaemic and algesic state. Possibly, insulin which is controlled by ATP sensitive potassium channel at the cellular level might also modulate antinociception exhibiting a cause effect relationship between them.
