Tasimelteon

Tasimelteon (trade name Hetlioz) is a drug approved by the U.S. Food and Drug Administration (FDA) in January 2014 for the treatment of non-24-hour sleep–wake disorder (also called Non-24, N24 and N24HSWD). In June 2014, the European Medicines Agency accepted an EU filing application for tasimelteon and in July 2015, the drug was approved in Europe for the treatment of non-24-hour sleep-wake rhythm disorder in totally blind adults, but not in the rarer case of non-24 in sighted people.
