      • Antipsychotics
        • Reduce positive symptoms of schizophrenia
        • Reduces delusions
        • Typical (original)
          • Typical antipsychotics block some the dopamine receptors because schizophrenics hae abnormally high levels of dopamine. These drugs reduce the effect of dopamine rather than the level of dopamine.
            • Chloropromazine
              • Side Effects
                • Tardive Dyskensia, uncontrollable facial spasms
        • Atypical
          • Atypical antipsychotics (clozapine) - exactly same as typical but only blocks some of the receptors for a few hours. Reducing tardive dyskenesia
      • Effectiveness
        • Chemotherapies do work
        • Relapse rates after one year
          • Chloropromazine - 25%
          • Chloropromazine+family - 2-23%

        • Clinicians advocate a mixture of chemotherapy and some form of psychotherapy

      • Antidepressants
        • SSR - Selective Serotonin Reuptake Inhibitor
          • e.g. Prozac
            • Abnormally low level of serotonin causes depression. Therefore prozac blocks the reuptake ports which in turn causes the serotonin to have more effect.

        • Anti-stress
          • e.g. BZ's - Benzodiazapenes
