The U.S. Food and Drug Administration (FDA) has given the green light to Eli Lilly's Zepbound (tirzepatide) for the treatment of moderate to severe obstructive sleep apnea (OSA) in adults struggling with obesity. This groundbreaking approval marks the first medication specifically designed to address OSA, offering a new avenue for managing this prevalent sleep disorder.

Zepbound, similar to medications like Ozempic and Wegovy, works by targeting receptors for gut hormones (GLP-1 and GIP), leading to reduced appetite and food intake. This weight loss mechanism is key to Zepbound's effectiveness against OSA, as excess weight is a major contributing factor to the condition. In clinical trials spanning 52 weeks, Zepbound demonstrated a significant reduction in apnea and hypopnea events, with many participants experiencing either remission or a substantial improvement in symptoms, alongside notable weight loss.

While Zepbound offers a promising new treatment option, it's important to be aware of potential side effects. These can include nausea, diarrhea, vomiting, constipation, stomach discomfort, injection site reactions, fatigue, allergic reactions (such as fever and rash), burping, hair loss, and gastroesophageal reflux disease (GERD). Furthermore, due to findings of thyroid C-cell tumors in rats during testing, individuals with a personal or family history of medullary thyroid cancer or multiple endocrine neoplasia syndrome type 2 should not use Zepbound. The FDA strongly advises all potential patients to consult their physician before starting Zepbound and to monitor for any adverse reactions.

Experts have welcomed the FDA's approval of Zepbound as a significant step forward in OSA treatment. Dr. Wendy Troxel, a sleep expert and licensed clinical psychologist, highlighted the challenges of adherence to current OSA therapies like positive airway pressure (PAP). She emphasized that Zepbound's ability to promote weight loss and reduce apnea events could provide a much-needed alternative, especially for those struggling with traditional treatments. Dr. William Lu, medical director of Dreem Health, echoed this sentiment, noting the interconnectedness of obesity and sleep apnea and the potential for Zepbound to improve overall health. He stressed the importance of getting tested for sleep apnea, which is crucial not only for diagnosis and treatment but may also be necessary for insurance coverage of the medication.

The FDA's approval of Zepbound is a significant advancement in the fight against obstructive sleep apnea. It provides a new, non-invasive treatment option for individuals with obesity who struggle with this condition, potentially improving their sleep quality, overall health, and well-being.
