After Pharma D one can not practice like a doctor as for that a MBBS degree is a must. A Pharma D qualified person has other career options in the pharmacological industry which are quite attractive. He can very well apply against the posts of Professor Associate, Pharmacology Tutor, Medical Advisor, Assistant Manager and Senior Manager in the pharmacological industry.
Anyway as per your proposition, you want to do MD from some foreign university and then practice as a doctor. There are some universities in foreign countries which have this type of combination that a Pharma D qualified person can do MD but the problem is when you come back to India then you will have to go through the screening test from MCI which is the apex medical body in our country and only after qualifying in that you can ask a particular state for registration which makes you equivalent to MBBS to practice medicine in the state. MCI has a inherent resistance to promote Pharma D candidates for becoming a full fledged doctor and it will be difficult for you to cross those hurdles. Another thing is such courses done from many foreign universities are not recognised by MCI. At the same time if you feel that you can get a job in some outside country after doing MD there and you have an inclination to settle down in abroad then you can think in that direction. You will have to apply in the respective foreign university and they require some minimum GRE score also along with English Language Proficiency test certification. Some of such institutions abroad are - University of Southern California, USA, Asian Medical University, Australia, Nottingham Trent University, UK etc. Each university has its own fee structure and that you will have to find out from their site.
So, what I will suggest is either you settle down with the job in India as per your present qualification or go for MD in Clinical Pharmacology in India itself which will give you opportunity to apply for higher level jobs in the pharmacological industry. There are many institution in India which have this course and some of them are - Maulana Azad medical college, New Delhi; Madras medical college, Chennai; Post graduate institute of medical education and research, Chandigarh; Christian Medical college, Vellore; Armed forces medical college, Pune; Lady Harding medical college, Delhi and Kasturba Medical college, Mangalore.
Knowledge is power.
