Combination therapy using atomoxetine and oxybutynin reduces OSA severity by approximately 60% by activating pharyngeal dilator muscles.

This combination drug is currently in clinical trials (Phase III) and not yet widely available. It targets the muscle function aspect of sleep apnea. If you are not a candidate for CPAP or weight loss drugs, you may want to ask your doctor about upcoming clinical trials for this specific combination.
