Pharmacological Study
Posatirelin is a TRH analogue. In a rat experimental model
of brain cholinergic deficit by lesion of the nucleus basalis
magnocellularis (nbM), posatirelin treatment rescued
cholinergic neurones of the nbM and their cholinergic
projections to the cerebral cortex (Sabbatini et al., 1998).
Posatirelin has been used in AD and VaD patients (Parnetti
et al., 1995, 1996). VaD patients treated with posatirelin
showed a significant improvement in intellectual performance,
orientation, motivation and memory as compared
to controls. The drug was well tolerated.

VaD patients treated with posatirelin showed a signicant improvement in intellectual performance, orientation, motivation and memory as compared to controls. e drug was well tolerated.
Uses
Posatirelin is a thyrotropin-releasing hormone analogue, used in the treatment of seizures and some neurodegenerative disease such as vascular dementia and Parkinson''s disease.
Definition
ChEBI: Posatirelin is an oligopeptide.
in vivo
Posatirelin (2 mg/kg, IP) increases the high-affinity Ca2+-ATPase in both 3- and 24-month-old hypoxic rats[1].
