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]
