Piracetam (Nootropyl) and aphasia

Excerpts from Smart Drugs & Nutrients

Piracetam (Nootropyl)

by Ward Dean, M.D., and John Morgenthaler

Piracetam is reported to be an intelligence booster and CNS (central nervous system) stimulant with no known toxicity or addictive properties. Piracetam is inexpensive (under $0.85 per day) and available by mail (see appendix A). The subjective effect described by some people is that piracetam, “wakes up your brain.” You'll find more personal accounts of the effects of this remarkable drug in the case histories and testimonials appendix. It's effects and safety are so impressive that piracetam prompted the creation of a new pharmaceutical category called nootropics.

The term nootropic comes from a Greek word meaning “acting on the mind.” Since the invention of piracetam by UCB Laboratories in Belgium, other pharmaceutical companies have been scrambling to develop their own nootropics. Some of them being researched now include; vinpocetine, aniracetam, pramiracetam, and oxiracetam. As yet, there is no nootropic compound that is FDA approved for sale in the US, but there is plenty of motivation on the part of pharmaceutical companies to get that approval. Financial analysts expect that the US market for these cognitive enhancers will soon be in excess of $1-billion per year (Pelton, 1989).

Piracetam is very similar in molecular structure to the amino acid pyroglutamate (see Pyroglutamate). Piracetam and pyroglutamate have the same “base” chemical structure, the 2-oxo-pyrrolidine, but they differ by the side chain. Pyroglutamate is 2-oxo-pyrrolidine carboxylic acid, and piracetam is 2-oxo-pyrrolidine acetamide.

Piracetam enhances cognition under conditions of hypoxia (too little oxygen), and also enhances memory and some kinds of learning in normal humans. Outside of the US, piracetam is used to treat alcoholism, stroke, vertigo, senile dementia, sickle cell anemia, dyslexia, and numerous other health problems (Pelton, 1989).

One of the most intriguing effects of piracetam is that it promotes the flow of information between the right and left hemispheres of the brain (Buresova, 1976). We know that the communication between the two sides of the brain is associated with flashes of creativity. This may also be the basis for piracetam's usefulness in the treatment of dyslexia (Dilanni, 1985). ..........next...............
