how to design a drug? - (Mar/06/2011 )

my lect told us to do esei on how to design a drug.. we need to describe the R&R, disease, and animal choose for pre-clinical test.. i dont understand ... what this question want..
she said we must find one drug and explain on how do they design it..

He probably means what steps need to be done when you discover a product that might be a good drug?

All the clinical tests etc? You need to describe those I think.
(describe the tests, what tests, how do they work, wich animals etc..)


How you go from product A to a drug...
