NO, the pharmD is not covered at all, but the PhD is free usually. IN med school, both degrees are paid for.
IN order to conduct research for a large pharmaceutical company, you will definitely need the PhD to be in pharmacokinetics / pharmacuetical sciences.
You may need the knowledge from the PharmD to be able to conduct research at the PhD level.
Many students in the PhD program are foreign students who did the bachelor of science in pharmacy in their country which is the same as in the US minus the clinical rotations. But it is even better preparation taking the bachelors in the other country since it is more basic science based and less clinical.
If you want job as a researcher in a pharmaceutical company, you will most likely need to get the PhD with research in Pharmacokinetics.
Perhaps if you want to do this and become a principal investigator (PI), maybe you should try to apply to medical school instead, MD/PhD, since your MD would be paid for!
