SW-SIA was potentiated by subanalgesic dose of CLO, and CLO analgesia was enhanced by SW-SIA. Animals tolerant to CLO analgesia were tolerant to SW-SIA, in contrast, CLO analgesia was potentiated in SW-SIA tolerant mice. Thus, SW-SIA and CLO analgesia partially share a common α2-adrenergic-dependent mechanism, for their production., Journal of Pharmacobio-Dynamics, 14(6), pp.357-361; 1991}, pages = {357--361}, title = {Participation of an α2-mediated mechanism in the production of forced swimming-stress induced analgesia in mice.}, volume = {14}, year = {1991} }
