High Quality Content by WIKIPEDIA articles! Fipexide (Attentil, Vigilor) is a psychoactive drug of the piperazine chemical class which was developed in Italy in 1983. It was used as a nootropic drug in Italy and France, mainly for the treatment of senile dementia, but is no longer in common use due to the occurrence of rare adverse drug reactions including fever and hepatitis. Fipexide is similar in action to other nootropic drugs such as piracetam and is structurally similar to another more well-known nootropic, centrophenoxine. Chemically, it is an amide union of parachlorophenoxyacetate and methylenedioxybenzylpiperazine, and notably, has been shown to metabolize to the latter, which plays a significant role in its effects.
