I believe that the anti-psychotic effects can be mostly attributed to dual 5-HT2a/5-HT2c antagonism. Ritanserin does not seem to bind to 5-HT2c receptors; that has important implications for its use as an anti-psychotic (e.g. it's not effective as often as we would like). Mianserin
should be a potent anti-psychotic because it effects both. Nefazadone blocks these receptors also, but not as potently as Mirtazapine or Mianserin. I like the last two drugs mentioned because they lack extrapyramidal side effects. They don't bind as well as some of the newer atypical anti-psychotics like Olanzapine to 5-HT2a receptors, but I bet they're just about as effective with fewer side effects. Note that I do not believe 5-HT2b is implicated is schizophrenia.I get all my binding data from

--I really love that site.Check out the following link for information on Mianserin for schizophrenia:
http://www4.infotrieve.com/search/databases/Results.asp?SR=1&QR=mianserin+and+schizophrenia&FY=1973&TY=2002&NR=10A similar search for Nefazadone and schizophrenia found no results.

> i remember you writing that Remeron was shown to work as an anti-psychotic... was that due to 5HT2A antagonism alone, or through antagonism of all 5HT2 receptors?
