The recommended starting dosage per Lawrence G. Leichtman, M.D. FAAP, FACMG is 75 mg per body weight in kilograms per day. Select from drop down, target mg/kg/day and desired weight to calcuate daily dosage.
Reduce dosage if hyperactivity is noticed. Dosages under 30 mg are below the threshold for a positive outcome. Start dosage after age six months: dosages for babies under six months, although harmless, are too small to be effective, i.e., not enough lipid peroxidation for Piracetam to be effective.
Piracetam has a half life of 6 to 8 hours, i.e., half of the ingested amount is metabolized in the first 6 to 8 hours. There is no known storage mechanism for Piracetam. Because of the short half life, it is desirable to dose three times a day, about 6 hours apart (never less than 4 hours), to keep a steady state level.
Many children and adults report sleep-related problems taking Piracetam before bed because it does seem to increase general CNS (central nervous system) activity.
Do not store liquid Piracetam above 25° Celsius (77° Fahrenheit). Keep the solution our of the reach of children. Refrigeration is not necessary, else crystallization will occur; store in cool, dark place. For flavored Piracetam follow the storage recommendation of the compounding pharmacy. Saturation point of Piracetam is 1 gram per cc.
Nootrópicos (smartdrugs, drogas inteligentes, potenciadores cognitivos) son sustancias artificiales (medicamentos como piracetam, hydergina, citicolina, fosfatidilserina, vinpocetina, etc.) o naturales (suplementos nutricionales, vitaminas, aminoácidos, hormonas, hierbas, etc. como vitaminas B, piroglutamato, Gingko Biloba, fenilalanina, DHEA, pregnenolona, etc.) que se utilizan para mejorar la capacidad cognitiva (memoria, atención, etc.) en personas con trastornos o normales.
