  • Antiphsychotics
    • Conventional Drugs (Neuroleptics)
      • Revolutionised treatment of disorders
        • E.g. Sz and Bi-Polar
      • Main focus
        • Positive symptoms
      • Reduce the amount of Dopamine
        • Binding to dopamine receptors
          • Blocks some but not all DP
      • Chloropromozine eliminates hallucinations and delusions
        • Associated with overactive DP system
    • Atypical Drugs
      • Helps patients who don't respond to Conventional drugs
      • Alleviates positive symptoms
        • Claims to help with Negative symptoms
          • Social withdrawal and lack of motivation
      • Don't act on DP system
        • Block serotonin receptors
          • No flooding of DP when off drugs
            • Less relapse rates
      • Risperidone used in hospitals
        • Improve STM
        • Useful for Rehab in living independently
          • Contribute to learning of social skills
    • Side Effects
      • DT v/strong
        • Produces SE's
          • Monitored
            • Dosage
      • Nausea
      • Dry mouth
      • Drowsiness
      • Changes in weight
      • Visual disturbances

            • Mouth
            • Hands
            • Feet
            • Tongue
            • Majorly irreversible
      • Teste et al (1999)
        • Found fewer people developed TD on Atypical drugs
          • Such as Clozapine
            • Compared to Conventional drugs
      • Termination of treatment
        • Leads to relapse and hospitalisation
        • May switch to Atypical drugs
    • Effectiveness
      • Not all patients are responsive to AP's
        • Chronic Sz can't be medicated
      • Some studies suggest Atypical drugs to be more effective than Conventional AP's
      • Placebo Effect
        • Davis et al
          • Suggested relapse rates were higher in placebo replaced drugs
            • Argued that withdrawal leads to flooding of DP
              • Relapse may be linked to withdrawal effects
      • Dose given during acute episode will be too high for maintenance
        • Can produce SE's
          • Crisis Point
