There are lots of relevant courses out there - Pharmaceutical Sciences, Pharmacology, Medicinal Chemistry, Drug Development etc.
You need to look carefully at the course content for these, go to some Uni Open Days if you can and hear the subject presentations to really understand what the courses are all about. Your choices will also depend on your A level subjects and predicted grades - the usual advice is to have one choice just above your predicted grades, 3 choices at your predicted grades (your most likely offers), and one choice a few grades below (as your Insurance choice).
