Aripiprazole, Abilify Maintena Collaborative Clinical Protocol

Sexual dysfunction is highly prevalent in schizophrenic patients, affecting up to 80% of men and women. Antipsychotic induced sexual side effects may be a barrier to treatment compliance. Antipsychotics such as Risperdal Consta and Invega Sustenna are known to have higher rates of causing prolactin elevations that may be implicated in sexual dysfunction. The basic premise of this study is to identify patients who believe they have experienced sexual dysfunction on Risperdal Consta or Invega Sustenna and switch to the alternative long acting injectable antipsychotic, Abilify Maintena which tends to lower prolactin levels. Measures of sexual sexual functioning using the self rated 5 item Arizona Sexual Experience Scale (ASEX) as the primary outcome measure will be made over a 3 month period to determine if such a switch is helpful.
