Dimoxamine is a memory adjuvant. Dimoxamine hydrochloride has been reported to facilitate the performance of naive rats in a massed trial shuttle box task. At doses that facilitated shuttle box responding, dimoxamine had no effect on unacclimated motor activity of rats nor on the rate of continuous avoidance responding by rats. Dimoxamine has a psychopharmacological profile that is different from other phenylalkylamines such as S-amphetamine and R-DOM. Dimoxamine may prove beneficial in the treatment of individuals having low or deteriorated levels of certain types of associative and psychomotor abilities. Dimoxamine substituted completely for LSD. Dimoxamine can be classified as a partial agonist of 5-HT receptors in sheep umbilical arteries.
