the drugs cefexime and cefaclor i just chose due to their shorter half life and good bioavailability in body, other wise i dont have any idea to do,
my teachers says that the most tough thing is to develope a method for HPLC study of drug in plasma it can take 3 months to 3 years, is that true?
and if the drug study method is already developed by other persons can i use that method or i should have to develop a new method for my study?
