Rotigotine is an agonist at all 5 dopamine receptor subtypes (D1-D5) but binds to the D3 receptor with the highest affinity. It is also an antagonist at α-2-adrenergic receptors and an agonist at the 5HT1A receptors. Rotigotine also inhibits dopamine uptake and prolactin secretion. It is FDA approved for the treatment of Parkinson's disease, restless legs syndrome. Dopamine antagonists, such as antipsychotics or metoclopramide, may diminish the effectiveness of Rotigotine. Common adverse reactions include nausea, vomiting, somnolence, application site reactions, dizziness, anorexia, hyperhidrosis, insomnia and dyskinesia.

Adrogolide is a chemically stable prodrug of the dopamine D1 receptor agonist A-86929. Adrogolide is rapidly converted in plasma to A-86929. A-86929 has high affinity and functional selectivity for the dopamine D1 receptor. Adrogolide has been in phase II clinical trials for the treatment of Parkinson's disease and cocaine abuse. However, this research has been discontinued. The adverse events associated with its use of adrogolide were of mild-to-moderate severity and included injection site reaction, asthenia, headache, nausea, vomiting, postural hypotension, vasodilitation, and dizziness.

(R)-SKF-83959 (MCL 202) is enantiomer of D1 receptor agonist SKF-83959. (R)-SKF-83959 is reported to be a functionally selective dopamine D1 and D5 receptors ligand with much lower affinity to dopamine D2 and D3 receptors. (R)-SKF-83959 like SKF-83959, produced dose related effects on overt behavior (eye blinking) and schedule-controlled performance in squirrel monkeys. (R)-SKF-83959 increases in eye blinking and decreases in rates of fixed-ratio responding. In contrast to the effects of its S-(-) enantiomer, was relatively devoid of behavioral activity up to doses that were approximately 10-fold greater than (R)-SKF-83959. Pretreatment with the selective D1- like receptor antagonist SCH 39166 dose-dependently antagonized increases in eye blinking produced by (R)-SKF-83959, confirming the involvement of D1 mechanisms in its effects.

Lisuride (DOPERGIN®), a highly active dopaminergic ergot derivative with prolactin-lowering properties, has a pronounced affinity for dopamine receptors. It may also act as an agonist at some serotonin receptors. Lisuride (DOPERGIN®) is concentrated within the pituitary where it acts on dopamine receptors which inhibit prolactin release. It can be used in the clinical conditions where a dopaminergic or prolactin-lowering effect is needed.
