whats it suppose to do and do u have any info on it?
piracetam is classified a nootropic drug. aka 'smart drug'. helps with learning memory and mood. ill copy and paste this from wiki
The mechanism of action of piracetam, as with
racetams in general, is not fully understood, but it influences neuronal and vascular functions and influences cognitive function without acting as a sedative or a stimulant.<sup id="cite_ref-Winblad2005_2-2" class="reference">
[3]</sup> Piracetam is a positive
allosteric modulator of the
AMPA receptor.<sup id="cite_ref-ahmedoswald_12-0" class="reference">
[13]</sup> It is hypothesized to act on
ion channels or
ion carriers<sup class="Template-Fact" title="This claim needs references to reliable sources from September 2008" style="white-space: nowrap;">[
citation needed]</sup>, thus leading to non-specific increased neuron excitability, while explaining its lack of
agonistic or
inhibitory effect on synaptic action (quite unlike most
neurotransmitters), and its low toxicity.<sup id="cite_ref-noot_13-0" class="reference">
[14]</sup> It has been found to increase blood flow and oxygen consumption in parts of the brain but this may be a side effect of increased brain activity rather than a primary effect or mechanism of action for the drug.<sup id="cite_ref-14" class="reference">
[15]</sup>
Piracetam improves the function of the
neurotransmitter acetylcholine via
muscarinic cholinergic (ACh) receptors which are implicated in
memory processes.<sup id="cite_ref-novel_15-0" class="reference">
[16]</sup> Furthermore, Piracetam may have an effect on
NMDA glutamate receptors, which are involved with
learning and
memory processes. Piracetam is thought to increase cell membrane permeability.<sup id="cite_ref-novel_15-1" class="reference">
[16]</sup><sup id="cite_ref-16" class="reference">
[17]</sup> Piracetam may exert its global effect on brain neurotransmission via modulation of
ion channels (
i.e., Na<sup>+</sup>, K<sup>+</sup>).<sup id="cite_ref-noot_13-1" class="reference">
[14]</sup> It has been found to increase oxygen consumption in the brain, apparently in connection to
ATP metabolism, and increases the activity of
adenylate kinase in rat brain.<sup id="cite_ref-ReferenceA_17-0" class="reference">
[18]</sup><sup id="cite_ref-18" class="reference">
[19]</sup> Piracetam appears to increase the synthesis of
cytochrome b5,<sup id="cite_ref-19" class="reference">
[20]</sup> which is a part of the
electron transport mechanism in
mitochondria. It also increases the permeability of the mitochondria of some intermediaries of the
Krebs cycle.<sup id="cite_ref-ReferenceA_17-1" class="reference">
