I've been using AdWords for the last 2 years and at first ran into a lot of issues where I thought something was unfair.
In all cases that I can remember (even one case where I needed to use a superlative "great"), I emailed them and explained why I felt something was unfair, and they re-considered in my favor. The one time they didn't (back in the days with TM issues), I requested that they refer it to their internal "panel" for a decision, which they did and again, the decision fell in my direction (i.e. favorable).
The key point is to document and explain. If it makes sense and is an issue of fairness, I've always had good results.
It's not uncommon for PPC campaigns to be halted when pharmacy issues are concerned. Even though you do not advertsie ther it is a simple numbers game, should they run you ads for a few cents/dollars a click and risk a huge lawsuit or not? As you are probably not registered as a pharmacy then it's an easy call, it's not right but you can see that exposing themselves to risk does not make sense.
We represent a pharmaceutical company who povide pre-manufacture testing to the big pharma companies, they hold a full UK licence for what they do yet it still was tricky getting ads up.
You have to accept that these things happen and move on.
