Yep, needs to be there
Information on action at 5-HT is already covered by nid:1485219985329; Extra of that card just notes that 5-HT2A antagonism reduces likelihood of extrapyramidal symptoms and not that it helps exert the antipsychotic effects. Going just based off that I wouldn’t add here.
Working off memory and a light google search, but doesn’t 5-HT work on the negative symptoms while D2 helps with positive symptoms? Could clarify that in extra if we want to add this
