tyramine and Mydriasis

tyramine has been researched along with Mydriasis in 2 studies

Mydriasis: Dilation of pupils to greater than 6 mm combined with failure of the pupils to constrict when stimulated with light. This condition may occur due to injury of the pupillary fibers in the oculomotor nerve, in acute angle-closure glaucoma, and in ADIE SYNDROME.

Research Excerpts

ExcerptRelevanceReference
" Mydriasis induced by the postsynaptic alpha 1-agonist phenylephrine was similar in both groups of patients tested, whereas pupillary dilation caused by the release of noradrenaline tyramine was markedly greater in patients with histories of ergotamine abuse."7.68Long-term ergotamine abuse: effect on adrenergically induced mydriasis. ( Alessandri, M; Beatrice, S; Briccolani-Bandini, E; Fanciullacci, M; Pietrini, U, 1992)
" ABT-200 also antagonized clonidine-induced mydriasis and increased the overflow of [3H]-norepinephrine in guinea pig hippocampal slices, manifestations of blockade of alpha-2 adrenoceptors in the central nervous system."3.69Preclinical pharmacological actions of (+/-)-(1'R*,3R*)-3-phenyl-1- [1',2',3',4'-tetrahydro-5',6'-methylene-dioxy-1'-naphthalenyl) methyl] pyrrolidine methanesulfonate (ABT-200), a potential antidepressant agent that antagonizes alpha-2 adrenergic recepto ( Brune, ME; Buckner, SA; Giardina, WJ; Hancock, AA; Kerkman, DJ; Lee, JY; Morse, PA; Oheim, KW; Stanisic, DS; Warner, RB, 1995)
