[Pharmacological treatment of obstructive sleep apnea syndrome].

Obstructive sleep apnea syndrome (OSAS) is a potentially life-threatening condition that is increasingly prevalent in developed countries. OSAS treatment involves multiple components, including general lifestyle modifications and specific interventions such as intraoral fixation devices and continuous positive airway pressure (CPAP). Surgical treatments, including correction of nasopharyngeal and oropharyngeal structures, orthognathic operations, and bariatric surgery, are used under strict indications. Until recently, pharmacological management was limited to nasal decongestants for rhinitis exacerbation and modafinil for daytime sleepiness. However, low compliance with non-surgical therapies and limited efficacy of some surgical procedures highlight the need for effective drug treatments for OSAS. Despite decades of research, a highly effective pharmacological therapy was not available until the past 6-7 years, when new agents and their combinations were evaluated. Randomization by OSAS endotype is now recognized as crucial in clinical studies. This review summarizes recent advances in OSAS drug therapy, primarily based on randomized clinical trials, with a focus on agents such as semaglutide, tirzepatide, atomoxetine-oxybutynin, solriamfetol, sultiame, and acetazolamide, as well as established drugs. Further research with long-term follow-up and consideration of OSAS endotypes and drug side effects is needed. The importance of combining different therapeutic approaches for OSAS is emphasized.
