Notably, in contrast to Gocovri (amantadine) — an approved therapy to treat levodopa-induced dyskinesia — PD13R did not affect the animals’ sleep, suggesting this new molecule may be a safer as well as effective in treating dyskinesia, the researchers noted. “We were very excited to see the robust…
