What is Gocovri, and what does it target in levodopa-induced dyskinesia?
Gocovri (amantadine) is used to treat levodopa-induced dyskinesia (LID) in people with Parkinson’s disease. It targets dyskinesia that develops as a side effect of long-term levodopa therapy, rather than treating Parkinson’s symptoms directly.
How does Gocovri work in the brain to reduce dyskinesias?
Gocovri works by modulating glutamate signaling. Specifically, amantadine helps reduce abnormal involuntary movements by acting on glutamatergic pathways involved in dyskinesia. This glutamate-related effect is why amantadine can lessen LID in many patients.
How is it different from taking amantadine “as needed”?
Gocovri is designed as an extended-release (once-daily) formulation, intended to provide more stable drug exposure over the day. That matters because LID can be time-linked to the “ups and downs” of levodopa levels, including symptoms that occur later in the day.
When during the day does LID improvement typically show up?
Because LID often tracks with levodopa dosing and fluctuating levodopa levels, Gocovri’s extended-release profile is intended to help with dyskinesia that can emerge later or persist through parts of the day. Exact timing and degree of response vary from person to person.
What side effects should people on Gocovri watch for?
Common amantadine-related side effects can include dizziness, sleep-related problems (such as insomnia), confusion, hallucinations, and swelling (edema). These risks are especially important in older adults or people with cognitive impairment, since amantadine can worsen confusion or cause hallucinations in some patients.
Are there alternatives if Gocovri doesn’t work or isn’t tolerated?
If LID persists or side effects limit use, clinicians may adjust levodopa dosing schedules and/or consider other dyskinesia-focused strategies. The right option depends on the pattern of dyskinesia, current Parkinson’s regimen, and tolerability.
