In Vitro | In vitro activity: Piracetam is able to significantly decrease the fusogenic and destabilising effect of Abeta 29-42, in a concentration-dependent manner. Preincubation of piracetam, at a piracetam/peptide ratio of 960, during 20 min before the addition of Abeta 29-42 prevents almost completely the mixture of the two fluorescent probes. Preincubation of piracetam with lipids prevents almost completely the release of calcein induced by the peptide in a dose-dependent fashion (piracetam/peptide ratios from 9.6 to 960). Piracetam (< 1.0 mM) preincubated with brain membranes enhances membrane fluidity in aged mice, rats and humans, as indicated by decreased anisotropy of the membrane-bound fluorescence probe 1,6-diphenyl-1,3,5-hexatriene (DPH). |

In Vivo | Piracetam (300 mg/kg once daily) significantly increases membrane fluidity in some brain regions of young and aged rats, but has no measurable effect on membrane fluidity in the young rats. Piracetam (300 mg/kg daily for 6 weeks) improves active avoidance learning in the aged rats only and elevates membrane fluidity in all brain regions except the cerebellum in the aged rats. Piracetam (300 mg/kg daily for 6 weeks) also improves NMDA receptor density in the hippocampus and on muscarinic cholinergic receptor densities in the frontal cortex and the striatum and to a lesser extent in the hippocampus of rats. Piracetam (500 mg/kg p.o. for 14 days) elevates N-methyl-D-aspartate (NMDA) receptor density by about 20% and normalizes the enhanced affinity of L-glutamate for the NMDA receptor in aged mice. Piracetam-treated withdrawn rats has higher the number of synapses than that observed in nonpiracetam-treated and alcohol-fed animals by up to 20%, the mechanisms leading to the synaptic reorganization took place at the mossy fiber level. |
