PHARMACOLOGY
PHARMACODYNAMICS
Risperidone is a selective monoaminergic antagonist with a high
affinity for serotoninergic 5-HT
2
and
dopaminergic D
2
receptors. Risperidone binds also to alpha
1
-adrenergic receptors, and with lower
affinity,
to
H
1
-histaminergic
and
alpha
2
-adrenergic
receptors.
Risperidone
has
no
affinity
for

cholinergic receptors.
The antipsychotic activity of risperidone is considered to be
attributable to both
risperidone and its active metabolite 9-hydroxy risperidone.
Central dopamine D
2
receptor antagonism is considered to be the mechanism of action by
which
