The relaxant effect of resveratrol on guinea pig isolated trachea (EC50 = 100 microM) was not due to interactions with histaminergic or cholinergic systems, but appeared to be influenced by beta-blockers, indomethacin and mepacrine. Antigen-induced contraction on sensitized trachea was partially antagonized by resveratrol. Resveratrol action may be partially related to arachidonic acid metabolism.

Abstract
The relaxant effect of resveratrol on guinea pig isolated trachea (EC50 = 100 microM) was not due to interactions with histaminergic or cholinergic systems, but appeared to be influenced by beta-blockers, indomethacin and mepacrine. Antigen-induced contraction on sensitized trachea was partially antagonized by resveratrol. Resveratrol action may be partially related to arachidonic acid metabolism.
