In reply to zyprexa or ritalin?? enhanced thinkig, posted by B2chica on November 29, 2007, at 10:17:52
To say in a blanket statement that zyprexa inhibits dopamine is misleading. It isn't that simple. While it does partially block dopamine receptors, it does not completely block them. It only binds for a short time, unbinds, rebinds, unbinds, on and on. It doesn't continuously bind and block. So dopamine communication does happen. It also stimulates more dopamine. Zyprexa increases, not decreases, dopamine in the brain. Many scientific studies show this effect. It also increases norepinephrine. Its effect on serotonin is either neutral or a slight decrease.
So it is more complicated than it looks. You seem to be feeling the benefits of increased dopamine and norepinephrine, with enough blockage going on to balance it all out.
