As im a pharamcy student so which field is suitable for me?

If you are interested in academia and R&D then I would suggest you to go for M.Pharm or Ph.D. It will not only add a higher degree and greater career opportunity but also will help you become a professor in top universities. You can try for M.Pharma courses under varied specializations. The courses you can go for the specializations like Medicinal Chemistry, Pharmaceutical analysis, Pharmacology & Toxicology etc. Or You can also go for MBA in Paharmacy as per your interest. It totally depends on your capability and interest.

Good Luck!
