Description
Curator's Comment: description was created based on several sources, including http://www.braintropic.com/nootropics/pramiracetam/

Scientists at Parke-Davis first synthesized Pramiracetam (brand name Pramistar) in the late 1970’s. It was first tested with Alzheimer’s patients. Seeing mixed results, the company tried it with major depressive disorder and licensed it as an orphan drug to Menarini. Pramiracetam is a central nervous system stimulant and nootropic agent belonging to the racetam family of drugs. Pramistar is used for the treatment of concentration and memory disturbances caused by the degeneration of brain cells or to diseases of the blood vessels supplying the brain, conditions that arise both in elderly patients (aged over 65 years). By stimulating choline uptake, pramiracetam indirectly modulates the release of acetylcholine and stimulates increased activity in the hippocampus. Because this part of the brain is absolutely crucial to the memory function, the general stimulation that pramiracetam creates can improve both the formation of new memories and the retention of reference or long-term memories. The increased activity in the hippocampus also increases cerebral blood flow, which enhances alertness and improves cognitive abilities in general. Pramiracetam may have other mechanisms of action as well. Researchers have hypothesized that in addition to its action in the brain, pramiracetam acts outside the brain in peripheral sites that rely on the adrenal glands. Animal studies suggest that pramiracetam may also increase or restore brain membrane fluidity, which facilitates cell signaling. Unlike many other racetam class nootropics, pramiracetam does not appear to strongly alter either wakefulness or emotional states. This can be explained by pramiracetam’s very limited influence on the production and release of serotonin, GABA and dopamine, the neurotransmitters that have the greatest effect on mood and anxiety levels.
