Apomorphine - Parkinson's drug

Apomorphine is a drug used to treat Parkinson's symptoms. It is available under the brand name APO-go.APO-go PEN

Apomorphine is a strong dopamine agonist.

Unlike other types of dopamine agonist drugs, which are taken as tablets or patches, apomorphine is given by subcutaneous injection or infusion. Subcutaneous means under the skin.

It is usually prescribed to give additional or alternative benefit for people who have had Parkinson's for some time.

Fluctuating Parkinson's symptoms

Apomorphine is usually prescribed to give additional or alternative benefit for people who have had Parkinson's for some time.

Apomorphine doesn't help everyone. But your specialist or Parkinson's nurse (if you have one) may suggest trying it if you:

  • have sudden or unpredictable changes in your symptoms, or
  • have severe 'off' periods that aren't controlled by other Parkinson's medications
  • are reasonably well when 'on'

The terms 'on/off' or 'motor fluctuations' refer to when people may find they can no longer rely on the smooth and even symptom control that their drugs once gave them.

How apomorphine is taken

Apomorphine can be given in different ways:

  • a pre-filled disposable pen you can use for intermittent injections as needed (APO-go PEN)
  • APO-go PFS syringeinfusion over a period of several hours via a portable, battery-driven pump (a syringe driver) using a pre-filled syringe (APO-go PFS)
  • infusion over a period of several hours using a portable, battery-driven pump (a syringe driver), a syringe and apomorphine in glass vials called ampoules. These need to be diluted using salt solution (saline)

For each option, the dose can be adjusted to suit you. If you only need to have intermittent injections of apomorphine between doses of your usual tablets, the APO-go PEN may be the best solution.

If you need more than 7 to 10 intermittent injections a day, you may be changed to a syringe driver. This change can greatly improve your quality of life.

If you use a pump, you can carry it in your pocket or a small pouch.

Ideally, this drug will be started under the guidance of a Parkinson's specialist.

Once you are settled on this treatment, and know how to use it, apomorphine can be continued at home.

Ideally, apomorphine will be started under the guidance of a Parkinson's specialist. Once you are settled on this treatment, and you and your carer (if you have one) have been trained in how to use it, apomorphine can be continued at home.

It acts very quickly and reliably so that people who need to be active at specific times can continue with their normal activities.

Apomorphine can cause short-term nausea and sickness, so an anti-sickness drug called domperidone (Motilium) will be given alongside apomorphine, beginning a couple of days before treatment is started.

The anti-sickness drug can be gradually reduced after a short while. For some people, it can be stopped completely.
