Aroxybutynin is (R)-Oxybutynin. Oxybutynin is an ancient (>50 year old) generic. Wikipedia notes that "the (R)-enantiomer is a more potent anticholinergic than either the racemate or the (S)-enantiomer, which is essentially without anticholinergic activity at doses used in clinical practice. However, (R)-oxybutynin administered alone offers little or no clinical benefit above and beyond the racemic mixture."
If you have sleep apnea and live in a country where you can buy most drugs OTC, this "Holy Grail" is something you can put together for yourself by tomorrow! Simply combine oxybutynin 5mg with atomoxetine 75mg, and done.

> In very simplified terms, the medication works by waking up the brain stem, preventing full muscle relaxation in the throat, while allowing the brain itself to rest during sleep.
I wonder if this is the same level of restorative rest one would get without keeping the brain stem awake?
