Hey
I'm also a pharmacist and was thinking of applying to med. school, but medicine in here is very lengthy and hard, it take like 10 years to get the degree and rotations, fellowships (specialization) etc...
Regarding your pharmacy degree i think it will be considered as premed as long as it has all the pre-request of med school ( i remember it was like 2 courses of biology, chemistry and physcis and math i think) which mostly you took during pharmacy. You will have to pass the mcat (entry exam for medicine), and most good universities require a high score.
good luck
