8.6 Prescribing Data

The prescribing of mental health medication in South Gloucestershire compared with nationally is reported in this section. Based on the British National Formulary, the main categories of mental health drugs are:

  • Hypnotics and Anxiolytics. Hypnotics are used to treat insomnia. Anxiolytics are used to treat anxiety states. The most commonly used anxiolytics and hypnotics are benzodiazepines. These medicines can cause dependence (psychological and physical) and tolerance
  • Drugs used in psychoses and related disorders. These include antipsychotic drugs (used to treat schizophrenia), antipsychotic depot injections (long acting medicines which tend to be used when compliance with oral treatment is unreliable) and drugs used for mania and hypomania (for example treatment of bipolar disorder)
  • Antidepressant drugs (for treating moderate to severe depression)
  • CNS stimulants and drugs used for Attention Deficit Hyperactivity Disorder (ADHD). Usually CNS stimulants are prescribed for children with severe and persistent symptoms of ADHD. However, treatment of ADHD often needs to be continued into adolescence and may need to be continued into adulthood
  • Drugs for dementia (data are not reported as Dementia is outside the scope of this needs assessment)

To enable comparison of local data with national data, the Age, Sex and Temporary Resident Originated Prescribing Unit (ASTRO-PU) is used. This is a nationally developed indicator for weighted prescribing volume based on individual GP practice population adjusted for patients’ age, sex and temporary residents. Data were obtained from the Commissioning Support Unit. The data source was ePACT.net.
