A variety of schools offer bachelor, master, and Ph.D. tracks in the pharmaceutical sciences. These degrees are useful to prepare for or extend a pharmacy education, but students must attend a 4-year professional program leading to the Doctor of Pharmacy, or Pharm.D., to practice as entry-level pharmacists.
But even if you can hack the academic rigor required to get a PhD, there may be good reason not to pursue such a degree: 1. A PhD takes twice as long as a bachelor's degree to complete. The average student takes 8.2 years to slog through a PhD program and is 33 years old before earning that top diploma.
