Extrapyramidal side effects of antipsychotics are linked to their association kinetics at dopamine D2 receptors

Abstract

Atypical antipsychotics show reduced extrapyramidal side effects compared to first generation drugs. Here the authors use time-resolved FRET to measure binding kinetics, and show that side effects correlate with drug association rates to the D2 receptor, while dissociation rates correlate with prolactin elevation.
