Almost all of the atypical antipsychotics, including
Abilify, block
(blockade) serotonin and dopamine receptors. Dopamine receptor blockade
reduces the effect of dopamine, a process that suppresses psychotic
symptoms, and causes numerous undesirable side effects. Serotonin receptor
blockade reduces the effect of serotonin, which, among things, results in an
increase in dopamine concentration. The two effects compete, and depending
on the part of the brain, one wins out over the other. On average, the
dopamine blockade wins in suppressing psychotic symptoms, and the serotonin
blockade increases dopamine concentration enough to win in other parts of
the brain, reducing the undesirable side effects.
(That's a quick version. For a longer version, you can visit my Web site,
and read more details.)
Histamine receptor blockade means that Abilify functions as an
antihistamine. So it might reduce allergy symptoms and cause sleepiness.
All of these statements are approximations that are true on average.
Individual people experience a wide range of effects, and the only way to
find out what the medication does for you is to try it.
