Olanzapine as long-acting injection (LAI) for acute and maintenance treatment of schizophrenia.?

Olanzapine (2-methyl-4-(4-methyl-1-piperazinyl)-10H-thieno[2,3-b][1,5]benzodiazepine) is one of the most commonly used drugs for atypical antipsychotics. Olanzapine has been approved by the FDA for the treatment of schizophrenia, acute mania in bipolar disorder, agitation associated with schizophrenia and bipolar disorder, and as maintenance treatment in bipolar disorder and psychotic depression. Zyprexa is Lilly’s top-selling drug, with sales of $4.2 billion last year.

Olanzapine's antipsychotic activity is mediated primarily by antagonism (blocking or inhibition) at dopamine receptors.

FDA required the manufacturers of all atypical antipsychotics to include a warning about the risk of hyperglycemia and diabetes with atypical antipsychotics.

Lilly is continuing to work with the agency on the new drug application (NDA). I think Lilly, has a come with a smart move like NDA, becoz., the FDA does not require any additional clinical trials for the continued review of the NDA. Per the agency's request, Lilly is preparing a proposed Risk Evaluation and Mitigation Strategy (REMS), which will be submitted in the near future. Hope this drug will not have the said side effects. A ray of hope for schizophrenia patients ? time will tell the story, best of luck Lilly....
