What is the mechanism of LSD?
-Does it bind to presynaptic or postsynaptic serotonin receptors?
-Is it an agnoist or antagonist at these receptors?
-What is the final effect? similar to serotonin or opposite of it?

Thanks.

I think LSD acts as serotonin agonist at presynaptic receptors in midbrain (interaction with 5HT1 and 5HT2 receptors)...


  #6

Ok here it is
the mechanism is not well known
but I do know that it acts principaly on the serotonin decreasing its activity
presynaptic inhibiting the liberation of serotonin

  #7

still a very good question

  #8

Yea, thats what I found too...
Serotonin is inhibitory.
it binds to presynap. recep (agonist)
therefore decrease release of serotonin.
so decrease inhibition
and therefore excitation...

I think that is responsible for its effects.
right?
