Step 1 : Introduction to the question "9. What is the actual name of PPA?"
...1. piperacillin 2. phenylpropanolamine 3. propoxyphene + APAP 4. 2-isopropyl-pentanol This was the one the FDA recalled. Piperacillin is Pipracil, an injection form penicillin {derivative;} propoxyphene + APAP is {Darvocet;} and 2-isopropyl-pentanol is just an organic compound I made up from the top of my head.
