Blonanserin, is a relatively new atypical antipsychotic for the treatment of schizoenia. Relative to many other antipsychotics, blonanserin has an improved tolerability profile, lacking side effects such as extrapyramidal symptoms, excessive sedation, or hypotension. As with many second-generation (atypical) antipsychotics it is significantly more efficacious in the treatment of the negative symptoms of schizoenia compared to first-generation (typical) antipsychotics.
