FDA-approved indications
Treatment of schizophrenia in adults.
Pharmacodynamics and Mechanism of action
The exact mechanism of action in the treatment of schizophrenia is unknown. But, it is hypothesized that lumateperone’s effects are mediated through antagonism (blocking) of the following two receptors in the brain:
– Postsynaptic dopamine D2 receptors
– Serotonin 5-HT2A receptors.
It has a high binding affinity for serotonin 5-HT2A receptors and a moderate binding affinity for dopamine D2 receptors.
Pharmacokinetics
Peak plasma concentration (Cmax)
After it is taken orally, the peak plasma concentration of lumateperone is reached approximately 1 to 2 hours later.
Ingestion of a high-fat meal with lumateperone may lower lumateperone peak plasma concentration by 33%.
Protein binding
About 97% of lumateperone is protein bound.

The terminal half-life of lumateperone is about 18 hours.
So, it reaches steady-state concentration after about 5 days.

Lumateperone is, obviously, contraindicated in patients who have had an allergic reaction to it.
