Aniracetam, another chemical cousin of piracetam, is also known as Draganon, Ro 13-5057, and Sarpul. It is considered even more powerful, and is used to treat more conditions. Aniracetam has much the same effect as piracetam without problems of toxicity or side effects. Its use as a smart drug is less common. The U.S. patent holder, Hoffman-LaRoche, has had problems gaining FDA approval for treating Alzheimer’s disease. So far the drug has not been officially approved in any country. Though it has great potential, aniracetam is primarily used in research, and is not yet widely available as a smart drug.
