It will depend on what area in the corporate world would you be keen on based on your interest area:
If you are a peoples person & like engaging with people then you could pursue MBA in HR & join HR in a dental mfg /product distribution company.
If you are keen on sales/marketing then you could pursue MBA in marketing and join a pharma /FMCG/dental product mfg setup in their sales/marketing team.
If you are keen in finance then you could also pursue MBA in finance & join an Equity Broking house and start tracking Pharma/hospital companies & thus use your medical knowledge in understanding the business of the said companies better.
You could also do MBA in hospital management & manage the administration of hospitals.
As I said, all will depend on your interest areas & career aspirations.
