Lumateperone is a partial
agonist of presynaptic D2
receptors and an antagonist
of postsynaptic D2
receptors.
↓ Positive, negative and
cognitive symptoms of
psychosis
Lumateperone efficiently
reduces dopamine signaling
Brain
Mesolimbic pathway
Blood vessel - blood brain
barrier
Lumateperone is taken orally
and absorbed from the
gastrointestinal tract
passive diffusion
Partial D2 receptor agonism
allows lumateperone to
stimulate D2 receptors under
low dopamine conditions,
while attenuating their
activation when dopamine
levels are high.
