The U.S. Food and Drug Administration on Friday approved Eli Lilly's weight-loss treatment, Zepbound, for obstructive sleep apnea, making it the first drug greenlighted to directly treat patients with the common sleeping disorder.

The agency's decision expands the use of Zepbound and could potentially pave the way for Eli Lilly to gain broader insurance coverage for the treatment.

The U.S. Food and Drug Administration said on Thursday there was no longer a shortage of Eli Lilly’s (LLY.N) blockbuster weight loss and diabetes drugs following a re-evaluation of their supply by the agency.
