I am from Nepal. Can I study B.Pharma in an institute of health science? Can you give me the detailed information and fee structure?

Yeah, you are eligible for it. However, you have to appear for institute specific entrance examinations. I'm providing some top institutions of India offering B.Pharma courses for foreign students. Have a look. http://manipal.edu/mcops-manipal/programs/program-list/bpharm.html ,
