AKOS BB-9852 ( also known in Russia as adamantylbromphenylamine) is an atypical psychostimulant and anxiolytic drug of the adamantane family that is used in Russia in the treatment of neurasthenia. Although the effects of the bromantane have been determined to be dependent on the dopaminergic and possibly serotonergic neurotransmitter systems, its exact mechanism of action is unknown, and it is distinct in its properties relative to typical psychostimulants such as amphe-tamine. Because of its unique aspects, bromantane has sometimes been described instead as an adaptogen and actoprotector.
