Eli Lilly's weight-loss pill, orforglipron, reduced breathing interruptions in adults with obstructive sleep apnoea by 12-13 episodes per hour more than placebo in two trials. The pill, approved for weight management, may offer an alternative treatment. Lilly plans to seek US approval for sleep apnoea by year-end.
