"There is a growing recognition among psychiatrists in the United States that non-adherence to medication is an even greater barrier to care for patients with schizophrenia than was previously understood, and that long-acting treatments can play a beneficial role in helping patients maintain a stable treatment regimen," said John Hayes, MD, vice president of Lilly Research Laboratories, in a company news release.
