Taltirelin (marketed under the tradename Ceredist) is a thyrotropin-releasing hormone (TRH) analog, which mimics the physiological actions of TRH, but with a much longer half-life and duration of effects,[1] and little development of tolerance following prolonged dosing.[2] It has nootropic,[3] neuroprotective[4] and analgesic effects.[5]

Taltirelin is primarily being researched for the treatment of spinocerebellar ataxia; limited research has also been carried out with regard to other neurodegenerative disorders, e.g., spinal muscular atrophy.[6][7][8]
