Your major won't matter to the admission committee that much. Study a discipline that means something to you so that you can be a more industrious pharmacist later on. Perhaps you are interested in the business of pharmacies, its products, or its service (B.A. in Business or Economics). Perhaps you are interested in the public health aspect of patient care (B.A. in Public Health). If you are interested in the sciences, biochemistry, microbiology, immunology, etc, are all great majors to have under your belt. Of course, remember that you need a good GPA...so whatever you choose to study, be sure you will maintain a GPA > 3.50.
It's great that you are asking this question now. Take a minute to think about how you want to steer your career in pharmacy and complete a bachelor's degree that can help you with that goal.
