Dimethylaminoethanol phosphate is a metabolite of dimethylaminoethanol (DMAE, also known as deanol) which is a precursor to the neurotransmitter acetylcholine. The drug was originally formulated as a drinkable ampule and used as a psychotonic brain stimulant to suppress fatigue. The objective is to allow the brain to optimize the production of acetylcholine (a primary neurotransmitter also involved in learning and memory). In addition, DMAE is an antioxidant which can reduce the proliferation of fibroblasts; it can be found in some anti-aging supplements. Today, Panclar® is no longer used but cognitive-enhancing drugs containing DMAE have been developed. In cancer research, DMAE can be used as a precursor to synthesize radiotracers for metabolic cancer imaging.
