You haven't posted anything that proves that, and it can't possibly be true that they have nothing to do with it. Obviously regulations cost money, so they're a factor in the cost of medication. For instance there has to be a bunch of thorough testing done (I've talked to statisticians who are involved in it and it's a long drawn-out process that takes a lot of people) and someone has to pay for that. But the thing is the regulations save lives, and honestly they help the companies too because they prevent some lawsuits. You could maybe argue that the benefit of preventing deaths (i.e. lawsuits) balances out the cost of the regulations, but that'd be pretty tough/impossible to calculate.
