2 Evidence-based review of current Parkinson’s disease treatments Subcutaneous apomorphine infusion treatment >

3 Learning objectives At the end of this section you will: Be aware of the current evidence base for subcutaneous apomorphine infusion in the treatment of advanced Parkinson’s disease Know the clinical findings for subcutaneous apomorphine infusion in the alleviation of motor complications Gain greater knowledge of the tolerability profile of subcutaneous apomorphine infusion

4 Most potent dopamine agonist Low bioavailability  parenteral use Clinical effect: Extent: identical to levodopa Onset: faster (5-20, max 60 min) Duration: shorter (  40 min) Randomised controlled study: ‘Off’  34% = 2 hours (p=0.02) Dyskinesias: Apo  35%, placebo 11% Review: ‘Off ’  46%, ‘ON’ with dyskinesias: +33% Dewey RB, et al. Arch Neurol 2001;58:1385-92. Deleu D, et al. Drugs Aging 2004;21:687-709. Apomorphine

5 Apomorphine is administered subcutaneously into the fatty tissue of the abdominal area, or alternatively into the upper thighs and arms Almost 100% of the drug is absorbed into the blood stream The apomorphine pump is about the size of a mobile phone and may be worn on a waistband of trousers or a skirt or alternatively hidden under clothes Frankel JP, et al. J Neurol Neurosurg Psychiatry 1990;53:96-101. European Parkinson’s Disease Association. Available at; http://epda.eu.com/medinfo/apomorphine (accessed 24 June 2010) Subcutaneous apomorphine infusion

6 Patient selection and information Reimbursement issues Baseline assessments including blood tests, Coombs test Premedication: domperidone 60 mg/d for ≥ 3 days Hospital admission Initial flow rate 1 mg/h which is gradually increased, depending on tolerability and efficacy Target dose: –Mean doses: studies where monotherapy was aimed at 100 mg/d –Add-on to oral treatment approximately 70 mg/d Concomitant reduction of oral medication, starting with dopamine agonists, monamine oxidase inhibitors, amantadine, then levodopa Subcutaneous apomorphine infusion: Practical issues

7 Instruction and training in pump handling and later supervision is given to patients and carers Infusion is given ideally by the patients themselves or if necessary carers European Parkinson’s Disease Association.

19 Subcutaneous apomorphine infusion is effective for treatment of the symptoms of Parkinson’s disease Subcutaneous apomorphine infusion has fewer contraindications than deep brain stimulation (DBS) Observations of reversible motor complication phenomena with subcutaneous apomorphine infusion are consistent with concept of continuous dopaminergic stimulation Randomised controlled studies of subcutaneous apomorphine infusion compared to oral treatment, intrajejunal levodopa and DBS are warranted Summary
