Common Forms Of Racetams
Piracetam is a derivative of GABA and has a range of effects on the CNS.
Piracetam facilitates cholinergic and excitatory amine neurotransmission (Giurgea, Greindl, & Preat, 1983; Vernon & Sorkin, 1991),
Increases regional cerebral blood flow (Jordaan, Oliver, Dormehl, & Hugo, 1996),
Alters neuronal membrane properties (Müller, Eckert, & Eckert, 1999).
It has been claimed that this agent improves learning and memory, but it is not clear which of its biological effects (e.g., neuroprotective, circulatory, or others) are responsible for the purported cognitive benefit (Malykh & Sadaie, 2010).
Piracetam is currently available as a nutritional supplement in United States
In 2009 piracetam was reportedly popular as a cognitive enhancement drug among students.
