why dont you take a year out, spend the time getting good work experiance (it is out there you just havnt looked/tried hard enough) and apply to medicine next year then you will have 4 med schools to apply to with a much better chance.
doing pharmacy with the hope of transfering to medicine would be highly competative (so much more than applying to med as school leaver with gap), then lets say you dont get to transfer (because they will expect you to have relevant work experiance which you clam you cant get) then you will have to do 4yrs of pharm before you can apply again.
also is nottingham the only place you applied to?
