I think you can go into marketing but its not that common i don't think, but i have heard of it. Quality control is another one you can go into.
You could get a job at a pharmacy journal, such as the PJ and C&D. They advertise for pharmacists with some background of journalism work.
Politics is another option as well. Whether you become a member of the all part pharmacist group or join the professional body (currently RPSGB, but whatever it will be in 2 years time) and campaign for the good of pharmacy.
