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,cite journal |author=Fukuchi I, Asahi T, Kawashima K, "et al" |title=Effects of taltirelin hydrate (TA-0910), a novel thyrotropin-releasing hormone analog, on in vivo dopamine release and turnover in rat brain |journal=Arzneimittelforschung |volume=48 |issue=4 |pages=353–9 |year=1998 |month=April |pmid=9608876 |doi= |url=] and little development of tolerance following prolonged dosing.
