Dimebon (Dimebolin) is an antihistamine drug which has been used clinically in Russia since 1983.[1] The regulation of therapeutic goods, that is drugs and therapeutic devices, varies by jurisdiction. ... In pharmacology and toxicology, a route of administration is the path by which a drug, fluid, poison or other substance is brought into contact with the body 1. ... An antihistamine is a drug which serves to reduce or eliminate effects mediated by histamine, an endogenous chemical mediator released during allergic reactions, through action at the histamine receptor. ...

Recently Dimebolin has attracted renewed interest after being shown to have positive effects on persons suffering from Alzheimer’s disease. Animal studies showing potential beneficial effects on Alzheimer's disease models were shown in Russian research in 2000.[2] Preliminary results from human trials have also been promising. In an initial six-month phase II trial, results have shown that at 12 months there was significant improvement over placebo. [3] Alzheimer redirects here. ...

Dimebolin is an orally active small molecule that has been shown to inhibit brain cell death in preclinical studies of Alzheimer's disease and Huntington's disease, making it a potential treatment for these and other neurodegenerative diseases. Research suggests that Dimebon may also have cognition-enhancing effects in healthy individuals, in the absence of neurodegenerative disease pathology.[4] Huntingtons disease or Huntingtons chorea (HD) is an inherited disorder characterized by abnormal body movements called chorea, and loss of memory. ...

Dimebon appears to operate through multiple mechanisms of action, both blocking the action of neurotoxic beta-amyloid proteins and inhibiting L-type calcium channels,[5] modulating the action of AMPA and NMDA glutamate receptors,[6] and may exert a neuroprotective effect by blocking a novel target that involves mitochondrial pores,[7] which are believed to play a role in the cell death that is associated with neurodegenerative diseases and the aging process. [8] Research is continuing in both Russia and western nations into the potential applications of Dimebon as a neuroprotective and potential nootropic. [9] Amyloid beta (Aβ or Abeta) is a protein fragment of 39-42 amino acids that is the main constituent of amyloid plaques in various neurological disorders, most prominently Alzheimers disease. ... Another, unrelated ion channeling process is part of ion implantation. ... The α-amino-3-hydroxy-5-methylisoxazole-4- propionic acid receptor (also known as AMPA receptor, AMPAR, or quisqualate receptor) is a non-NMDA-type ionotropic transmembrane receptor for glutamate that mediates fast synaptic transmission in the central nervous system (CNS). ... The NMDA receptor (NMDAR) is an ionotropic receptor for glutamate (NMDA (N-methyl d-aspartate) is a name of its selective specific agonist). ... Nootropics, popularly referred to as smart drugs and smart nutrients, are substances which boost human cognitive abilities (the functions and capacities of the brain). ...
