Quick Answer: What receptors does olanzapine work?

The activity of olanzapine is achieved by the antagonism of multiple neuronal receptors including the dopamine receptor D1, D2, D3 and D4 in the brain, the serotonin receptors 5HT2A, 5HT2C, 5HT3 and 5HT6, the alpha-1 adrenergic receptor, the histamine receptor H1 and multiple muscarinic receptors.

Does olanzapine block serotonin receptors?

Olanzapine is a serotonin-dopamine-receptor antagonist indicated for use in the treatment of schizophrenia and other psychotic disorders. The affinity of olanzapine for neuroreceptors is similar to that of clozapine.

Does olanzapine block the D2 receptor?

Conclusions: Olanzapine is a potent 5-HT2 blocker and shows a higher 5-HT2 than D2 occupancy at all doses. However, its D2 occupancy is higher than that of clozapine and similar to that of risperidone.

What neurotransmitters does olanzapine affect?

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.

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).
