Dopamine receptor pharmacology.

@article{citeulike:3061402, abstract = {Although antipsychotic drugs originally helped to discover dopamine receptors, the five dopamine receptors presently identified and cloned are facilitating the search for and discovery of more selective antipsychotic and antiparkinson drugs.

The D2-like receptors, D2, D3, and D4, have approximately similar sensitivities to dopamine, but bromocriptine and raclopride are both about two orders of magnitude weaker at D4, whereas clozapine is one order more potent at D4, as compared with D2 and D3.
