Lurasidone and Blonanserin


Recommended Posts

"Atypical antipsychotic drugs (AAPDs) have been suggested to be more effective in improving cognitive impairment in schizophrenia than typical APDs, a conclusion supported by differences in receptor affinities and neurotransmitter efflux in the cortex and the hippocampus. More potent serotonin (5-HT)2A than dopamine (DA) D2 receptors antagonism, and direct or indirect 5-HT1A agonism, characterize almost all AAPDs. Blonanserin, an AAPD, has slightly greater affinity for D2 than 5-HT2A receptors. Using microdialysis and UPLC-MS/MS, we compared the abilities of the typical APD, haloperidol, three AAPDs, blonanserin, lurasidone, and olanzapine, and a selective 5-HT1A partial agonist, tandospirone, and all, except haloperidol, were found to ameliorate the cognitive deficits produced by the N-methyl-d-aspartate antagonist, phencyclidine, altering the efflux of neurotransmitters and metabolites in the rat cortex and nucleus accumbens. Blonanserin, lurasidone, olanzapine and tandospirone, but not haloperidol, increased the efflux of cortical DA and its metabolites, HVA and DOPAC. Olanzapine and lurasidone increased the efflux of acetylcholine; lurasidone increased glutamate as well. None of the compounds significantly altered the efflux of 5-HT or its metabolite, 5-HIAA, or GABA, serine, and glycine. The ability to increase cortical DA efflux was the only shared effect of the compounds which ameliorates the deficit in cognition in rodents following phencyclidine."

Would these purpose any benefit to us? I've ever seen anyone on the forum discuss them before. Maybe some of you more well experienced users will have something to say in regards to this.
