Antipsychotic drugs, formerly called ‘(?)’, are also known as neuroleptics
major tranquillisers
Antipsychotic drugs, formerly called ‘major tranquillisers’, are also known as (?)
neuroleptics
An oral antipsychotic drug should be used in combination with (?) in patients with schizophrenia?
Psychological therapy
When choosing an antipsychotic drug to treat schizophrenia, what factors do you need to consider? (5)
- The potential to cause extrapyramidal symptoms (including akathisia)
- Cardiovascular adverse effects
- Metabolic adverse effects (including weight gain and diabetes)
- Hormonal adverse effects (including increase in prolactin concentration)
- Patient and carer preference
How long should a patient receive an antipsychotic drug at an optimal dose before it is deemed ineffective?
4-6 weeks
Clozapine: 8-10 weeks
Doses should be started low and slowly titrated up to the minimum effective dose according to patient response and tolerability (optimal dose)
Should you prescribe more than one antipsychotic drug at a time?
NO
except in exceptional circumstances (e.g. clozapine augmentation or when changing medication during titration)
Due to increased risk of adverse effects such as extrapyramidal symptoms, QT interval prolongation and sudden cardiac death
Which drug should be offered if schizophrenia is not controlled despite the sequential use of at least 2 different antipsychotic drugs (one of which should be a second-generation antipsychotic drug), each for an adequate duration?
Clozapine
When should clozapine be offered to patients with schizophrenia?
If not controlled despite the sequential use of at least 2 different antipsychotic drugs (one of which should be a second-generation antipsychotic drug), each for an adequate duration
When should long-acting depot injectable antipsychotic drugs be considered for patients with psychosis and schizophrenia?
When it is a clinical priority to avoid non-adherence
The (?)-generation antipsychotic drugs (also known as typical or conventional) act predominantly by blocking dopamine D2 receptors in the brain.
