Pharmacotherapy in obstructive sleep apnoea: a clinical guide.
Obstructive Sleep Apnoea (OSA) is a common, yet underdiagnosed disorder, with significant health implications. Continuous positive airway pressure (CPAP) remains the reference standard and first-line therapy. However, successful CPAP usage is influenced by factors such as access, cost, tolerance, patient education, early troubleshooting, and long-term adherence, all of which can be challenging and resource-demanding. Adding therapeutic options to the armamentarium is therefore welcome. There is a need for clinicians to be abreast of all the available therapeutic options for treatment of OSA.
We conducted an extensive literature review of the published studies that were conducted using non-CPAP pharmacotherapeutic modalities for OSA.
This narrative review summarises the current landscape of OSA pharmacotherapy, focusing on mechanisms of action, clinical trial evidence, and endotype-based selection strategies. Emerging therapies such as the atomoxetine-oxybutynin combination and topiramate show promise in reducing severity of OSA, and improving sleep quality. GLP-1 receptor agonists like liraglutide and tirzepatide offer benefits beyond reducing the severity of OSA. Other agents such as sulthiame, solriamfetol, and pitolisant have also demonstrated efficacy. Wake-promoting agents like modafinil and armodafinil target the commonest symptom of OSA, sleepiness.
This review provides a practical, endotype-aligned summary of pharmacologic options for the management of OSA.
