Obstructive sleep apnea (OSA) is a condition that affects many people, causing daytime sleepiness and affecting their daily lives. While positive airway pressure (PAP) masks have been effective in managing OSA, they do not always eliminate excessive daytime sleepiness (EDS). Researchers have been working to find medications that can provide relief for those struggling with EDS. In a recent study, 14 clinical trials involving 3,085 individuals with OSA and EDS were reviewed to determine the effectiveness of three anti-fatigue medications: solriamfetol, armodafinil-modafinil, and pitolisant.
The study found that all three medications were more effective than placebos in combating EDS. However, solriamfetol offered the most significant statistical difference, indicating its potential as a promising treatment option. Armodafinil-modafinil and pitolisant were also found to have some efficacy, although not as consistently as solriamfetol. It is important to note that side effects were observed with armodafinil-modafinil and solriamfetol, with patients being more likely to discontinue the use of armodafinil-modafinil. Further research is needed to understand the long-term effects of these medications.
Potential Applications
The findings from this study have implications beyond OSA and EDS. Researchers suggest that these medications may also be effective in treating related conditions such as chronic fatigue syndrome and long COVID. However, more research is needed to explore their effectiveness in these contexts. Additionally, it is essential to investigate the underlying causes of these conditions for more targeted treatment options.
Considerations and Individualized Treatment
While two of the medications studied are already prescribed for OSA and EDS, pitolisant is still under review by the US FDA. The choice of medication depends on various factors, including the patient’s health profile. However, it is crucial to be mindful of potential side effects, such as increased blood pressure associated with solriamfetol. Care must be taken when prescribing these medications to ensure the safety and well-being of patients.
The prevalence of OSA is substantial, affecting as many as a billion people globally. With such a high number of individuals impacted by this condition, there is a pressing need for improved and more effective treatment options. It is estimated that 15 to 30 percent of people in North America have a diagnosis of OSA, and this number could be even higher considering the undiagnosed cases.
The search for medications to alleviate excessive daytime sleepiness in individuals with OSA is ongoing. The study discussed here sheds light on the comparative efficacy of solriamfetol, armodafinil-modafinil, and pitolisant. While solriamfetol emerged as the most promising option, further research is needed to understand the long-term effects and potential applications of these medications. As the prevalence of OSA continues to rise, finding better treatments for OSA-related symptoms, including EDS, remains a critical goal in improving the quality of life for those affected.
