Application

Mianserin hydrochloride has been used:
  • as a reversible antagonist for serotonergic -protein coupled receptor (GPCR) - G-protein protein-coupled receptor (S7.1R)
  • as an antidepressant in hippocampal astrocytes to test its effect on brain-derived neurotrophic factor (BDNF) mRNA expression
  • as a 5-hydroxytryptamine (5-HT) receptor antagonist to study its effect on serotonin modulation

Biochem/physiol Actions

Mianserin is a tetracyclic compound with sedative property. It lacks anticholinergic activity and is not effective on serotoninergic mechanisms. Mianserin is eliminated post biotransformation as hydroxylation, N-oxidation and N-demethylation products.
Antidepressant; antagonist/inverse agonist at 5-HT2 serotonin receptors; also blocks the H1 histamine receptor and the α2 adrenoceptor.

Mirtazapine is a new antidepressant with a unique mode of action: it preferentially blocks the noradrenergic alpha2-auto- and heteroreceptors held responsible for controlling noradrenaline and serotonin release. In addition, mirtazapine has a low affinity for serotonin (5-HT)1A receptors but potently

In this study, we demonstrate that clozapine and other atypical antipsychotic drugs induce a paradoxical internalization of 5-hydroxytryptamine-2A receptors in vitro and a redistribution of 5-hydroxytryptamine-2A receptors in vivo. We discovered that clozapine, olanzapine, risperidone and the putative atypical antipsychotic
