Onapgo Shows Lasting Benefits for People Living with Parkinson’s Disease

A new long-term study has shown encouraging results for Onapgo (apomorphine hydrochloride), a treatment designed to help manage motor symptoms in people with advanced Parkinson’s disease. Onapgo is used as an add-on therapy and is delivered through a continuous under-the-skin infusion. It works by imitating the activity of dopamine, a chemical in the brain that is often in short supply due to Parkinson’s. Reducing Off Time, Improving Good On Time One of the biggest challenges for people living with Parkinson’s is the return of symptoms between doses of standard medication — a period known as “off time.” The study found that Onapgo significantly reduced these difficult periods and increased “good on time,” when symptoms are better controlled. These improvements were not only seen early in treatment but remained steady over the full three years of follow-up. A Meaningful Difference for Many People Participants in the study reported real and lasting improvements in how they felt, with more than 85% of people saying they experienced noticeable relief compared to before starting Onapgo. Even after three years, most participants continued to feel better, which highlights the potential of this therapy to support quality of life over the long term. Safety and Tolerability Over Time The research also showed that Onapgo was generally safe and well tolerated. Some people experienced side effects, such as nausea, sleepiness, or dizziness, especially when starting treatment or adjusting the dose. However, these symptoms became less common over time. Small lumps near the infusion site were a frequent but usually mild concern, and no serious infections were reported. Hope for Long-Term Symptom Management These findings offer promising evidence that Onapgo can help reduce the daily impact of motor symptoms and give people with Parkinson’s more hours of better-controlled movement. While no single treatment can fully solve the challenges of Parkinson’s, studies like this one give hope for improving quality of life and providing more reliable symptom relief over time.
