Obstructive sleep apnea (OSA) affects nearly 1 billion people globally, causing frequent interruptions in sleep where individuals stop breathing 20 to 100 times a night. This condition not only leaves people feeling tired and groggy but can also lead to serious health problems like heart disease, stroke, and cognitive decline. Currently, a common treatment is the CPAP (Continuous Positive Airway Pressure) machine, but it’s not ideal for everyone.
For individuals like Roger Schwalm, who struggles with the discomfort of using a CPAP machine, there is hope in a new treatment: the weight-loss drug tirzepatide, sold under the brand names Mounjaro and Zepbound. This drug, already FDA-approved for managing diabetes and obesity, has shown promise as the first effective drug therapy for sleep apnea.
Researchers at UC San Diego have conducted studies that indicate tirzepatide may help alleviate sleep apnea symptoms, potentially due to its effects on weight loss and other factors. Clinical data revealed that patients who used tirzepatide lost an average of 20% of their body weight, and improvements were seen in systolic blood pressure, cardiovascular risk markers, and sleep apnea-specific issues, such as hypoxic burden.
Dr. Atul Malhotra from UC San Diego notes that tirzepatide could be improving sleep apnea by reducing weight or possibly influencing brain function. The drug has also shown positive effects on behaviors like reducing alcohol and tobacco consumption, which may further help in managing sleep apnea.
While there is excitement about this potential treatment, more clinical trials are needed to understand the long-term effects of tirzepatide on sleep apnea. Currently, the drug is known to cause short-term side effects like nausea, vomiting, and diarrhea. Additionally, if used for weight loss, tirzepatide is generally considered a lifelong treatment, and researchers are still studying whether the same will apply to sleep apnea treatment.
As researchers continue their work, patients like Schwalm may finally find relief from their sleep apnea without the need for a CPAP machine. Other CPAP alternatives, such as EPAPs, nerve stimulation implants, and mandibular advancement devices, are also being explored, offering more choices for individuals struggling with this widespread condition.
