The clinical utility of long-term oral levodopa therapy in Parkinson disease (PD) is often limited by the emergence of motor complications. Over time, many patients with PD experience regular and/or unpredictable “off” periods, despite taking optimized oral medication regimens, with a major negative impact on their ability to undertake routine activities of daily living and consequently on their overall quality of life. One established approach for treating patients experiencing off periods and controlling motor fluctuations refractory to conventional oral drug therapy is the subcutaneous administration of the dopaminergic agonist apomorphine. This article outlines how the pharmacokinetic properties of apomorphine underpin its efficacy for the treatment of PD and provides practical guidance for the 3 main approaches in which it is used: subcutaneous intermittent apomorphine injection as a “rescue” therapy for off states, subcutaneous continuous apomorphine infusion for PD patients with intractable motor fluctuations as an alternative to other dopaminergic treatment, and in the apomorphine response (or challenge) test for assessment of dopamine-induced motor response in patients thought to have PD, or in establishing the optimal tolerated dose of apomorphine in patients already known to have PD. Also discussed is the management of potential adverse events with subcutaneous administration of apomorphine, the majority of which are mild and easily managed in practice. The importance of a multidisciplinary PD team in the optimal management of PD patients is now recognized, in particular the role of the specialist PD nurse.
