Study Notes
Combined Antipsychotics (Antipsychotic Polypharmacy)
- Combined antipsychotic medication prescriptions are common, often long-term and include LAI antipsychotics, quetiapine, and FGAs.
Poor Response to Antipsychotic Monotherapy
- Common reasons for prescribing combined antipsychotics include poor response to monotherapy and switching between medications
- Young age, male gender, increased illness severity, chronicity, poorer functioning, inpatient status, and schizophrenia diagnosis are associated with combined antipsychotic use
- There is limited evidence that combined antipsychotics are more effective than single antipsychotics
- A meta-analysis found that augmentation with a second antipsychotic lacked double-blind, high-quality evidence for overall efficacy
- Switching from polypharmacy to monotherapy is uncertain, but may benefit patients in a majority of cases
Long-Term Antipsychotic Treatment
- Monotherapy is superior to polypharmacy for discontinuation in schizophrenia but polypharmacy has a lower likelihood of mortality and psychiatric hospitalizations
- Clozapine, and LAI antipsychotics, are associated with lower risk of rehospitalization than monotherapy
Key Concepts
- Combining antipsychotics with different receptor profiles may offer better therapeutic efficacy, lower side effects, and improved adherence
Adverse Effects
- Potential harm, significant side effects are linked to combined antipsychotic regimens
- Increases prevalence and severity of EPS, metabolic side effects, diabetes, risk of hip fracture, sexual dysfunction, grand mal seizures, and prolonged QTc
- Inconsistent evidence on relationship between polypharmacy and mortality with some studies showing no increased mortality in schizophrenia patients on polypharmacy
- A study found a significant increase in mortality in patients on multiple antipsychotics concurrently
- Long-term polypharmacy may have weak links to mortality rates but no clear causal association
- 10-year study indicated multiple prescriptions might lead to increased risk of death
- There is no strong evidence linking the severity of psychiatric illness with combined antipsychotic use
Conclusion
- Precaution is needed when prescribing multiple antipsychotics due to potential adverse effects and unclear mortality impacts
The Use of Combined Antipsychotic Medications in Clinical Practice
- Association between combined antipsychotic medications and greater side-effect burden
- Documentation of rationale for prescribing combined antipsychotics, benefits, side effects, and medico-legal concerns is critical.
Clinical Context
- Numerous combinations exist but limited data on risk-benefit profiles
- Clinical disadvantages of antipsychotic polypharmacy include increased side effects, higher total dosage, increased risk of drug interactions, poor medication adherence, and difficulty determining optimal long-term regimen
Current Practice and Evidence
- Antipsychotic polypharmacy is established despite limited supporting evidence
- Treatment guidelines suggest combination should be used primarily for refractory psychotic illness
- Clozapine is often the preferred treatment but underutilized
Supportive Practices
- Clozapine augmentation potentially supports efficacy
- Aripiprazole addition may aid in reducing body weight in patients on clozapine and normalize prolactin levels in patients on haloperidol
- Caution is needed when combining with risperidone LAI due to regulatory concerns
Conclusion
- Evidence suggests that routine use of combined, non-clozapine, antipsychotic medications may be best avoided
