FDA Approves Extended-Release Amantadine (Gocovri) for Treatment of Dyskinesia

The Parkinson’s Foundation alerts the community that extended-release amantadine capsules (GOCOVRI™) have been approved by the US Food and Drug Administration (FDA) for the treatment of dyskinesiaAbnormal, involuntary body movements that can appear as jerking, fidgeting, twisting and turning movements; frequently caused by dopaminergic medications to treat Parkinson’s. in people with Parkinson's disease receiving levodopa-based therapy. This new approval was announced by the manufacturer on August 24.

Below is a statement on this approval from Michael S. Okun, M.D., National Medical Director, Parkinson’s Foundation:

“Today, the US Food and Drug Administration (FDA) announced the approval of an extended-release amantadine capsule called GOCOVRI™. This drug will provide a practical once a day solution for dyskinesia management and reducing “off” time When medication is not working well. Symptoms become more noticeable and movement becomes more difficult.. Patients who are currently well managed using multiple doses per day of generic amantadine for dyskinesia will not likely derive additional symptomatic benefits from switching to once a day dosing; however, patients experiencing side effects from amantadine may wish to discuss options with their neurologist.

"Both GOCOVRI and generic amantadine use is linked to a risk of side effects such as dizziness, hallucinations or blotching on the skin of the legs.  If you are considering starting this medicine or switching to this medicine we recommend consulting with your doctor.

"In an independent Parkinson’s Foundation study prior to this approval, we found that generic amantadine use improved dyskinesia in patients.  However, amantadine use does have a risk of side effects including insomnia and hallucinations. GOCORVI has been designed to limit the risk of these complications and it will not carry generic amantadine’s warning for insomnia.”
