Cabergoline is an ergot derived-dopamine D2-like receptor agonist. It has high affinity for D2, D3, and 5-HT2B receptors (Ki=0.7, 1.5, and 1.2, respectively).Cabergoline permits rapid and effective hormonal and tumor control by normalizing prolactin-producing pituitary adenomas levels.Cabergoline acts as a potent agonist of D2, D3 and 5-HT2B receptors.

Perphenazine dihydrochloride is an orally active dopamine receptor and histamine-1 receptor antagonist that acts on D2 (Ki: 0.56 nM), D3 (Ki: 0.43 nM), and 5-HT2A (Ki: 0.6 nM) receptors, and also binds Alpha-1A adrenergic receptors.

Ro 10-5824 dihydrochloride is a selective agonist of dopamine D4 receptor partial, (Ki of 5.2 nM).
