General Chemistry helped a lot more than organic, we have done barely anything related to organic (even though we do organic while we're actually in pharmacy school, nothing has applied to other courses).
Gen chem helped with acid/base stuff and pka's of drugs, still wasn't that prevalent. We do a course entitled "medicinal chemistry" but basically that's just memorizing drug structures and important functional groups, so it's yet again on its own with no carry over from the previous chemistries.
I was really disappointed to be honest with the amount of chemistry (or math for that matter) in the program, it's basically absent. I thought you'd be studying interesting reactions that occured once a drug was in the body etc, it's just all memorization.
If chemistry isn't your fortay, I wouldn't be worried. Pharmacy courses are their own style of material, just as biology is separate from chemistry. That style unfortunately just involves an assload of memorization and little problem solving, ironically.
