Quizplus · Accepted Answer

Antipsychotic drugs primarily antagonize both D₂ and 5HT_2A receptors. The phenothiazine, butyrophenone, and thioxanthine drugs are referred to as "typical" because they all primarily block D₂ receptors. Unlike these three antipsychotic drug classes, the atypical drugs reduce serotonin activity more than they reduce the activity of dopamine, and for that reason they cause a significantly lower incidence of extrapyramidal syndrome (EPS).
