8-Hydroxy(di-n-propylamino)tetralin (8-OH-DPAT; 0.1-50 mg/kg i.p.) evoked a dose-dependent mydriatic response in conscious mice (ED50 = 5.8 mg/kg i.p.) which was maximal after 10 min. 8-OH-DPAT (2 mg/kg i.p.)-induced mydriasis was attenuated by the alpha 2-adrenoceptor antagonists, idazoxan (1 and 3 mg/kg i.p.) and yohimbine (1 and 3 mg/kg i.p.), by the 5-HT1 receptor antagonists, pindolol (10 mg/kg i.p.) and quipazine (2 mg/kg i.p.), and by the selective 5-HT1A receptor antagonist, (-)-N-tert… CONTINUE READING
