Piracetam is a nootropic. Piracetam is a drug that may enhance cognition and memory, may slow brain aging, may increase blood flow and oxygen to the brain, may aid stroke recovery, may improve Alzheimer's, Down's syndrome, dementia, and dyslexia, among other diseases and conditions. Piracetam may be classified as a psychoactive stimulant. Piracetam's chemical name is 2-oxo-1-pyrrolidine acetamide; it shares the same 2-oxo-pyrrolidone base structure with 2-oxo-pyrrolidine carboxylic acid (pyroglutamate). Piracetam is a cyclic derivative of GABA. Piracetam is one of the racetams. Piracetam is prescribed by doctors for some conditions, mainly myoclonus, but is used off-label for a much wider range of applications. Some countries consider it a supplement rather than drug.
Piracetam is usually supplied in 800-mg tablets or capsules. Some bulk or nutritional suppliers supply it in a powder form. The recommended dosage varies based on the indication, usually ranging from 1.6-9.6 grams daily (2-12 pills daily). Some people report faster results when taking 1-2 pills every hour for 4~6 hours or taking 4-8 pills at once for the first few days to notice an effect.
For blood coagulation, clotting, and vasospastic disorders such as Raynaud's phenomenon or deep-vein thrombosis, the most effective treatment range is a daily dose of 4.8 to 9.6 grams divided into three daily doses at 8 hours apart.
The LD-50 for oral consumption in humans has not been determined, though some internet anecdotes indicate some people can tolerate more than 50 grams per day.
