Piracetam was subjected to the hydrolytic, oxidative, thermal and photolytic stress, according to ICH guideline Q1A (R2). The drug depicted degradation only in basic conditions, while it was stable to other stress conditions (acidic, neutral hydrolysis, thermal and photolytic conditions). A total of one degradation product was formed, which were separated on a BEH column employing an isocratic ...
Mechanochemical reaction of solid piracetam with the inorganic salts LiCl and LiBr yields ionic co-crystals which are also co-drugs, characterized by markedly different thermal properties with respect to pure components, also depending on the method for preparation and/or conditions of measurements; single crystal and powder X-ray diffraction at variable temperatures, DSC, TGA, hot stage micros...
Subchronic administration of BR-16A (Mentat), a compound herbal formulation, and the nootropic agent, piracetam, augmented learning acquisition and retention of learning in normal rats, as well as in states of cognitive deficits induced by prenatal undernutrition, postnatal environment impoverishment and sodium nitrite hypoxia. The test paradigms used were step-down latency in a passive avoidan...
