Background: Apomorphine is an option for continuous dopaminergic therapy in Parkinson's disease (PD). However, its effects in varied populations are limited due to its availability.

Objective: To assess the efficacy and outcomes of apomorphine in Indian patients.

Materials and methods: Retrospective analysis of PD patients who underwent apomorphine response test (ART), along with the subset, who went on to apomorphine pumps.

Results: Twenty-nine confirmed PD patients underwent ART and all PD patients showed good clinical response. 19 subjects developed adverse events which included: nausea (n-15, 51.7%), vomiting (n-10, 34.4%), sleepiness (n-08; 27.5%), yawning (n-07, 24.1%), postural hypotension (n-03, 10.3%), dizziness (n-03, 10.3%), and profuse sweating (n-01, 3.4%). Apomorphine pumps were initiated in six subjects, with significant clinical improvement. Adverse events on pump included subcutaneous nodules, nausea, hypersexuality. Two among them subsequently discontinued the pump primarily due to financial constraints.

Conclusions: Apomorphine adds up to the armamentarium for treatment of PD patients in India with good clinical responses.
