I found out months ago that atypical antipsychotics can be classed into a number of categories.
Anyway, as can be noticed, a lot of scientific names of antipsychotics end with either pine (e.g. Quetiapine, Clozapine) or done (e.g. Risperidone, Lurasidone) or include the word pip (Aripiprazole, Brexpiprazole: only ones in class) or rip (Cariprazine: only one in class). Some antipsychotics are considered to be related to each other in some way. That is why they are named like that.
It is not a big deal. It is just something I found out. Actually the scientific name of all atypical antipsychotics contains one of these words I think.
