The hydrate of tatirelin, a thyrotropin releasing hormone (TRH) analogue with potential neuroprotective, analgesic and central nervous system-stimulating (CNS)/analeptic activities. Taltirelin mimics the physiological actions of TRH on the CNS while exerting a minimal effect on the release of thyrotrophin (TSH) from the anterior lobe of the pituitary. Like TRH, the mechanism of action of this agent in the CNS has not been fully elucidated mechanism, but may involve various cerebral monoamine pathways. Compared to TRH, taltirelin has a much longer half-life and duration of effects. Check for active clinical trialsusing this agent.
