My suggestion for you will be M.Pharma after B.Pharma. There is no use of doing M.Sc in chemistry after B.Pharma. B.Pharma graduates can improve their future prospects by going for higher studies. The most commonly chosen course is the 2-year Master of Pharmacy (M.Pharma), which is offered by all top colleges in India. The student can pick from a wide range of specializations such as Industrial Pharmacy, Clinical Pharmacy, Pharmaceutical Chemistry, Pharmaceutical Analysis, Quality Assurance, Drug Regulatory Affairs, etc. Many colleges also offer a Master of Science (M.Sc) in Pharmacology and Pharmaceutical Chemistry which are also two-year programmes. The candidate must clear GPAT (Graduate Pharmacy Aptitude Test) in order to get admission to M.Pharma course.
