🔬 How This Medicine Works (Pharmacology)
Pharmacokinetics
How It Works
This medicine exerts its therapeutic effects primarily through antagonism of dopamine D2 receptors and serotonin 5-HT2A receptors in the brain. It also interacts with other neurotransmitter systems, including histamine H1, muscarinic M1, and alpha-1 adrenergic receptors, which contributes to its side effect profile. By blocking these receptors, it helps stabilize mood and reduce psychotic symptoms.
