Lurasidone is primarily used in the treatment of schizophrenia and bipolar depression. It works by altering the activity of certain natural substances in the brain, helping to restore the balance of neurotransmitters. For schizophrenia, it helps manage symptoms such as hallucinations, delusions, and disorganized thinking. In bipolar depression, it is effective in reducing depressive episodes without triggering manic episodes. Lurasidone is often chosen for its favorable side effect profile, particularly its lower risk of weight gain and metabolic issues compared to other antipsychotics. It is typically taken orally, once daily, with food to enhance absorption. Regular monitoring by a healthcare provider is essential to ensure its effectiveness and manage any potential side effects.
