1948 V. Erspamer in Acta Pharmacologica 4 245 It is suggested that the parent substance of the adrenaline-like principle in the salivary extracts should be called ‘Octopamine’.

1970 R. Passmore & J. S. Robson Compan. Med. Stud. II. xv. 32/2 Octopamine is a much weaker adrenergic receptor activator than noradrenaline and replacement by it of a portion of the noradrenaline released by nerve stimulation could result in a diminished response of the effector tissue.
