Everybody should know there is way more to animal research than what you talk about here. Your first sentence makes it sound like there is no independent animal research whatsoever and that everything is driven by money, which is blatantly false. Lots of neurophysiological research for instance has nothing to do with pharmaceutics at all, and is purely done to figure out how brains work. Moreover experiments done both with macaques and humans show there are relatively lots of brain areas that do the same task, which is exactly one of the reasons it actually makes sense using macaques for such research.
"PCP, which has a violence inducing affect on humans is sometimes used as a horse tranquilizer."
First of all, PCP _can_ have a violence inducing effect, you make it sound like it always does. Second, so what? This doesn't prove that animal research is misleading. If you give a human the same dosage per weight as you'd use to tranquilize a horse, the human would be tranquilized as well. Just like with ketamine which is used as an animal tranquillizer a lot and at the same time in lower doses has all kinds of effects on humans. And the other way around works as well btw: if you give animals less than the dosage needed to tranquillize them, you see similar effects like dizziness.
