Background:
Piracetam-d6is intended for use as an internal standard for the quantification of piracetam by GC- or LC-MS. Piracetam is a nootropic cyclic GABA derivative.1It is a positive allosteric modulator of AMPA receptors and enhances binding of the NMDA antagonist MK-801 to rat forebrain membranes.2,3Piracetam (1 mM) protects against amyloid-β-induced decreases in the mitochondrial membrane potential, as well as decreases in neurite outgrowth in the presence of NGF, in PC12 rat adrenal medulla cells.4It prevents scopolamine-induced amnesia in a passive avoidance test in mice when administered at a dose of 30 mg/kg.5Formulations containing piracetam have been used in the treatment of myoclonus.
