Clinical potential of lurasidone in the management of schizophrenia

Therapeutics and Clinical Risk Management

Lurasidone is a new second-generation antipsychotic approved in October 2010 by the Food and Drug Administration for the treatment of schizophrenia. Like other second-generation antipsychotics, lurasidone is a powerful antagonist of D(2) dopamine and 5HT(2A) serotonin receptors, but differs from the other second-generation antipsychotics in its action profile for certain receptors. Lurasidone is the second-generation antipsychotic with the greatest affinity for 5HT(7) receptors and has a high affinity for 5HT(1A) serotonin receptors, compatible with favorable effects on cognitive function and an antidepressant action. By contrast, lurasidone has a low affinity for and α(1) α(2C)-adrenergic and 5HT(2C) serotonin receptors, and no affinity for histaminergic H(1) or muscarinic M(1) receptors, suggesting a better tolerability profile than the other second-generation antipsychotics. Lurasidone has demonstrated its efficacy in several short-term trials in acute schizophrenia, promptly and significantly reducing total Positive and Negative Syndrome Scale and Brief Psychiatric Rating Scale scores compared with placebo. Several long-term studies are in progress to assess its efficacy in the maintenance treatment of schizophrenic patient...Continue Reading
