  • Image not available. The pathophysiology of schizophrenia may occur in one or more different neurotransmitter systems.
  • Image not available. The clinical presentation of schizophrenia is characterized by positive symptoms, negative symptoms, and impairment in cognitive functioning.
  • Image not available. Comprehensive care for individuals with schizophrenia must occur in the context of a multidisciplinary mental healthcare environment that offers psychotropic medication management and comprehensive psychosocial services.
  • Image not available. A thorough patient evaluation (e.g., history, mental status exam, physical exam, psychiatric diagnostic interview, and laboratory analysis) should occur to establish a diagnosis of schizophrenia and to identify potential co-occurring disorders, including substance abuse and general medical disorders.
  • Image not available. Given that it is challenging to differentiate among antipsychotics based upon efficacy, side-effect profiles become important in choosing an antipsychotic for an individual patient.
  • Image not available. Pharmacotherapy algorithms should emphasize monotherapies with antipsychotics of optimal efficacy: side-effect ratios and progress to medications with greater side-effect risks and then to combination regimens only in the most treatment-resistant patients.
  • Image not available. Adequate time on a given medication at a therapeutic dose is the most important variable in predicting medication response.
  • Image not available. Long-term, maintenance antipsychotic treatment is necessary for the vast majority of patients with schizophrenia in order to prevent relapse.
  • Image not available. Thorough patient and family psychoeducation should occur, including education about the illness, symptoms, prognosis, medication, psychosocial treatments, and methods to improve adaptive functioning.
  • Image not available. Pharmacotherapy decisions should be guided by systematic monitoring of patient symptoms, preferably with the use of brief symptom rating scales.
