Atomoxetine and oxybutynin combination reduces AHI in OSA patients but may increase heart rate and blood pressure, requiring risk/benefit assessment.

A combination of atomoxetine and oxybutynin can slightly reduce sleep apnea severity, but it may raise heart rate and blood pressure. Because the benefit is small and risks exist, it is not a first-line treatment and requires careful medical supervision.

ModerateQualifiesMEDIUM confidence
The combination was reported in the MARIPOSA study... did lead to small but statistically significant reductions in the apnea hypopnea index (AHI)... there are small increases in heart rate and blood pressure in subsets of patients receiving these medications which must be considered in the context of overall risk/benefit assessments.
