Antipsychotic drugs: a class of drugs that alleviate schizophrenia. Neuroleptics: a class of antipsychotic drugs, traditionally dopamine receptor blockers: chlorpromazine is the first neuroleptic discovered. Typical neuroleptics: a major class of antischizophrenic drugs that share antagonist activity at dopamine. D2 receptors: these were so good at relieving symptoms of schizophrenia that a dopaminergic explanation of the disease became dominant. Now, typical neuroleptics may reduce negative symptoms. Disturbances of mood or affective disorders are among the most common of all psychiatric complaints. The first generation of effective antidepressant medication were the monoamine oxidase inhibitors. Antidepressants: a class of drugs that relieve the symptoms of depression.
