Ibuprofen is generic, it can be made by anyone. Dimetap and Robitussin are cough medicines formulated from generic active ingredients, just buy the generic form. Advil is just branded ibuprofen. Pfizer doesn't make shit on anything but patented medications, that's why they are skirting regulations any way they can. When only the bottom line matters, everything else is just an obsiicle to keeping your company afloat while enriching upper management.
