Dear applicant if you want to work in Corporate Pharmacy sector then you can opt for the Bachelor of Pharmacy course after your 12th. So if you have B.pharm degree you can use it later for the betterment of your knowledge and work in any sector. And yes after completion of B.Pharm degree there are few colleges in India offering MBA in Pharmacy degree and the some other colleges have dual degree of M.Pharm + MBA. So you do have the access to pursue both Pharmacy and MBA higher studies at the same time.

Good luck!!!
