High-potency antipsychotics have a higher affinity for dopamine receptors and less for alpha-adrenergic and muscarinic receptors. (msdmanuals.com)
Low-potency antipsychotics, which are rarely used, have less affinity for dopamine receptors and relatively more affinity for alpha-adrenergic, muscarinic, and histaminic receptors. (msdmanuals.com)
