What neurotransmitters does olanzapine affect?

It may work by blocking receptors for several neurotransmitters (chemicals that nerves use to communicate with each other) in the brain. It binds to alpha-1, dopamine, histamine H-1, muscarinic, and serotonin type 2 (5-HT2) receptors. Olanzapine was approved by the FDA in 1996.

What does olanzapine do to neurotransmitters?

The main effect that olanzapine has is to block some dopamine receptors in the brain, correcting the overactivity of dopamine. Olanzapine also has effects on other neurotransmitters in the brain such as serotonin (5-HT), which may also contribute to its beneficial effects.

Does olanzapine block serotonin and dopamine?

Olanzapine is a serotonin-dopamine-receptor antagonist indicated for use in the treatment of schizophrenia and other psychotic disorders.

Does olanzapine affect serotonin?

Here, we report that olanzapine enhances the SSRI-induced increase in extracellular serotonin (5-HT) levels and antidepressant-like effects by inhibiting GABAergic neurons through 5-HT6 receptor antagonism in the dorsal raphe nucleus (DRN).

Why does olanzapine block dopamine?

Olanzapine blocks serotonin receptors more strongly than dopamine receptors, which is a proposed mechanism for effects on negative symptoms in schizophrenia.

Does olanzapine help anxiety?
