Antipsychotic drugs have been classified as typical or atypical. To achieve an effective antipsychotic effect with typical antipsychotic drugs, e.g. haloperidol, a dopamine D2 receptor blockade of about 70% seems necessary.

theory: the indirect mode of therapeutic action of d2-blocking antipsychotic drugs To resolve this paradox, it has been proposed in several publications [ 101 , 102 , 103 , 105 ] that the D2-blocking agents act indirectly, the final common target of antipsychotic drugs of all classes being the D1 receptor, or the mechanism of synthesis of cAMP controlled by this receptor. 1g fe ecu pinout pdf Atypical antipsychotics have greatly enhanced the treatment of schizophrenia.
