What is Caplyta (lumateperone)?
Caplyta is the brand name for the active ingredient lumateperone. The mechanism of action of lumateperone for the treatment of schizophrenia or bipolar depression is not fully understood. However, its effectiveness could be through a combination of blocking the activity at central serotonin 5-HT2A receptors and central dopamine D2 receptors.
In clinical trials, after one week of treatment with Caplyta, patients started to show improved Positive and Negative Syndrome Scale (PANSS) total scores. PANSS is a scale used to measure the severity of schizophrenia symptoms. Symptoms continue to improve the longer you take the drug.
Caplyta is available in capsule form, in the following doses: 42mg.
The recommended dosage of Caplyta is 42 mg once daily, with food, to control the symptoms of schizophrenia. Dose titration is not required. Caplyta can be taken alone or in combination with lithium or valproate for bipolar depression.
