| CLINICAL PHARMACOLOGY
Mechanism of Action
The mechanism of action of lurasidone, as with other drugs having efficacy in schizophrenia, is unknown. It has been suggested that the efficacy of lurasidone in schizophrenia is mediated through a combination of central dopamine Type 2 (D2) and serotonin Type 2 (5HT2A) receptor antagonism
Indications and usage
| INDICATIONS AND USAGE

The efficacy of LATUDA in schizophrenia was established in four 6-week controlled studies of adult patients with schizophrenia.
The effectiveness of LATUDA for longer-term use, that is, for more than 6 weeks, has not been established in controlled studies. Therefore, the physician who elects to use LATUDA for extended periods should periodically re-evaluate the long-term usefulness of the drug for the individual patient [see Dosage and Administration].
