If you've got the grades, reapply to a university that has a pharmacy school.
Pharmacy is a 5-year program, not a graduate program - but the first two years are like any other major - the required humanities, math, writing, foreign language, and science courses - of course, you'd want some pharmacy or chemistry-related courses as some of your electives then.
If you don't have the grades yet, go to the nearest community college to get your prerequisites out of the way and improve your GPA, then reapply as an incoming 3rd year student. But it won't be like "starting over" You'll just have to carry a little heavier course load to get in those 100 and 200 level pharmacy courses.
Undergraduate credit transfers easily - and there's no time limit on them - I had my 2 writing courses, 2 chemistry courses, and an economics course transfer after 18 years! (I don't advise you to wait that long, though
)
Good luck.
