Is this really a homework assignment you want us to do??? Aaargh! I'll point you in a direction so you can learn how & why the expiration dates are what they are. Don't know there is a real "list" - its what the drug company included in the ANA they submitted so is drug specific.
Good Manufacturing Practices for Finished Pharmaceuticals - www.fda.gov
There is also a program called SLEP - Shelf Life Extension Program for the military - administered through the FDA - www.fda.gov which follows the status of drug products which have been kept by the military beyond the labeled expiration dates &/or have been kept "outside" the labeled conditions (temperature, humidity, etc..)
