I read that Aleve is a non-prescription strength of the prescription drug, Anaprox. Aleve contains napercin, a non-prescription form of presciption Naprosyn. I understand Aleve is a non-steroid anti-inflamitory over-the-counter pain reliever (NSAIDS). My question: what are the ingredients in: Napercin, Naprosyn, Naproxen, & Anaprox?
