Summary
This trial tests a combination of two medications, atomoxetine and oxybutynin, to reduce sleep apnea severity. Previous studies have shown that the combination of these medications can significantly reduce obstructive sleep apnea severity by increasing upper airway muscle activity during sleep. It focuses on patients with specific traits that might make them more likely to respond well to this treatment. The medications help keep the airway open by affecting muscle control and reducing collapsibility.
Who is the study for?
This trial is for people with suspected or diagnosed obstructive sleep apnea who have recent drug-induced sleep endoscopy results. It's not for those with uncontrolled medical conditions, other major respiratory disorders, using certain medications like hypnotics or SSRIs, pregnant or nursing women, and individuals with a range of specific health issues such as severe hypertension, heart failure, liver/kidney disease.
What is being tested?
The study tests whether Atomoxetine-plus-oxybutynin therapy (AtoOxy) effectively reduces the severity of obstructive sleep apnea in patients. Researchers will identify which patients benefit most based on traits measured during initial sleep studies.
What are the potential side effects?
Potential side effects from Atomoxetine and Oxybutynin may include allergic reactions like angioedema or urticaria, mood changes including mania or depression in young adults under 24 years old, constipation, difficulty urinating due to urinary retention, seizures in those predisposed to them.

Other Research
Common treatments for Obstructive Sleep Apnea (OSA) include pharmacological agents like Atomoxetine and Oxybutynin. Atomoxetine, a selective norepinephrine reuptake inhibitor, increases norepinephrine levels, which can enhance upper airway muscle tone and reduce airway collapse during sleep.
Oxybutynin, an anticholinergic agent, reduces muscle spasms and airway resistance through its antimuscarinic effects. These mechanisms are crucial for OSA patients as they offer a pharmacological means to reduce OSA severity by improving airway patency, providing an alternative or complement to traditional treatments like CPAP.
