Study Notes
Licensed Maximum Doses
- The text mentions the maximum licensed doses of antipsychotics inside and outside the European Union (EU).
-
Inside the EU, the maximum doses for some drugs include:
- Paliperidone depot: 525 mg every 3 months
- Risperidone (Janssen): 50 mg every 2 weeks
-
Outside the EU, the maximum doses for some drugs include:
- Pimavanserin: 34 mg/day
- Ziprasidone: 160 mg/day
- The maximum doses for various oral and long-acting injection antipsychotics are listed in tables, grouped by drug category (FGAs, SGAs).
Minimum Effective Doses
- Table 1.1 suggests the minimum doses of antipsychotics likely to be effective in first- or multi-episode schizophrenia.
- Most patients will respond to the suggested dose, but some may require higher doses.
- Doses should be considered approximate due to individual response variations.
- The table only covers oral treatment with commonly used drugs.
General Principles of Prescribing
- The lowest possible dose should be used.
- Dose increases should occur only after one or two weeks of assessment in which the patient shows poor or no response.
- Response to antipsychotic treatment should be assessed using rating scales and documented in patient records.
- Patients receiving antipsychotics should undergo close monitoring of their physical health, including blood pressure, pulse, ECG, plasma glucose, and plasma lipids.
- When withdrawing antipsychotics, the dose should be reduced slowly in a hyperbolic regimen to minimize withdrawal symptoms and rebound psychosis.
- Generally, antipsychotic polypharmacy should be avoided due to the increased risk of adverse effects.
- Antipsychotics should not be used as "when necessary" sedatives.
- Combinations of antipsychotics should only be used if a single antipsychotic, including clozapine, proves ineffective.
