In a pharmacological context it appear's not alot is know about
mechanisms of action etc..:

Is there anybody out there in the rest of the world, who could give me
some hints about pharmacology. Maybe the FDA read the net? I'm the
first to admit that in high doses you could see extrapyramidal effects
due to reduced transmitter release. But, what Ca2+ channels are
invovled; is the blocked diffuses, related to DA, GLU, 5-HT or what? In
Uruguay references are hard to come by...can anybody help!
Thanks...
With reference to science please repond to me on kojak at biocel.edu.uy, on
other matter's, particularly the Betty Martin debate "don't bother!"
