Study Notes
Relative Adverse Effects of Antipsychotic Medications
- Amisulpride has a moderate risk of weight gain and a high risk of prolactin elevation.
- Aripiprazole, Brexpiprazole, Cariprazine, Iloperidone, Lurasidone and Pimavanserin have a very low risk of adverse effects.
- Asenapine has a low risk of sedation and a moderate risk of weight gain.
- Benperidol has a high risk of sedation, akathisia, parkinsonism and prolactin elevation.
- Chlorpromazine, Clozapine, Flupentixol, Fluphenazine, Haloperidol, Paliperidone, Perphenazine, Promazine, Trifluoperazine and Zuclopenthixol have a high risk of sedation, akathisia, parkinsonism and prolactin elevation.
- Clozapine has a high risk of weight gain.
- Fluphenazine has a low risk of sedation.
- Haloperidol has a high risk of sedation, anticholinergic effects and prolactin elevation.
- Lumateperone has a moderate risk of sedation, weight gain and prolactin elevation.
- Loxapine has a moderate risk of sedation and weight gain.
- Olanzapine has a high risk of sedation, weight gain and prolactin elevation.
- Pimozide has a low risk of sedation and a moderate risk of prolactin elevation.
- Pipothiazine has a moderate risk of sedation, weight gain and prolactin elevation.
- Quetiapine has a high risk of sedation.
- Risperidone has a moderate risk of weight gain and hypotension.
- Sertindole has a high risk of parkinsonism and prolactin elevation.
- Ziprasidone has a low risk of sedation and a moderate risk of anticholinergic effects and prolactin elevation.
Treatment Algorithm for Poor Adherence to Antipsychotic Medication
- If the patient is forgetful or disorganized simplify drug regimen, reduce anticholinergic load, consider compliance aids and consider depot/LAI treatment.
- If the patient lacks insight or support discuss with the patient and consider depot/LAI.
- If the patient is poorly tolerating treatment discuss with the patient and switch to a drug with a more favorable side-effect profile.
Treatment Algorithm for First-Episode Schizophrenia
- Agree on the choice of antipsychotic medication with the patient and/or carer.
- If this is not possible, start with a second-generation antipsychotic medication.
- Titrate the dose to the minimum effective dose.
- Adjust dosage regimen according to therapeutic response and tolerability/safety.
- Assess over 2–3 weeks.
- If the medication is effective continue at the established effective dose, consider switching to depot/long-acting injection before discharge.
- If there is no effect after 2-3 weeks change the drug.
- If the medication is not tolerated or there is poor medication adherence, discuss with the patient and change the drug if the poor adherence is related to poor tolerability or consider early use of depot/long-acting injection if the poor adherence is related to other factors.
- If the medication is not effective after 2-3 weeks consider Clozapine.
Treatment Algorithm for Relapse or Acute Exacerbation of Schizophrenia
- Investigate social or psychological precipitants.
- Provide appropriate support and/or therapy.
- Continue usual drug treatment.
- Consider adding a short-term sedative or switching to a different, more acceptable antipsychotic medication.
- Discuss medication choice with the patient and/or carer.
- Assess over 6–8 weeks.
- If treatment is ineffective switch to Clozapine.
Notes on Treatment for Relapse or Acute Exacerbation of Schizophrenia
- First-generation drugs may be slightly less efficacious than some SGAs.
- FGAs should probably be reserved for second-line use due to the possibility of poorer outcomes compared with SGAs and a higher risk of movement disorder, particularly tardive dyskinesia.
- Choice should be based largely on comparative adverse effect profile and relative toxicity.
- Patients seem able to make informed choices based on these factors, although in practice they have been involved very rarely in drug choice.
- Allowing patients informed choice seems to improve outcomes.
- Where there is prior treatment failure (but not confirmed treatment refractoriness), olanzapine or risperidone may be better options than quetiapine.
- Olanzapine, due to evidence suggesting slight superiority over other antipsychotics, should likely be tried before clozapine unless contraindicated.
- Before considering clozapine, ensure adherence to prior therapy using depot/LAI formulation or plasma drug level monitoring of oral treatment.
- Time to response is increased, and total response decreased in exacerbation of multi-episode schizophrenia.
- Where there is confirmed treatment resistance (failure to respond to adequate trials of at least two antipsychotic medications), evidence supporting the use of clozapine (and only clozapine) is overwhelming.
