Fipexide (aka attentil and vigilor) is a psychoactive drug of the piperazine class which was developed in Italy in 1983. It was used in Italy and France for the treatment of senile dementia but is no longer in common use due to undesirable side effects including fever and hepatitis.

Sample Use Guides

In Vivo Use Guide

Geriatric patients received 600 mg fipexide daily for a period of 3 weeks. Treatment with fipexide was associated with a significant improvement in each and all monitored symptoms and signs to an average extent of 60%, relative to placebo. Overall, 85% of the patients given fipexide experienced clinical improvement to a greater or lesser degree.

Route of Administration: Oral

In Vitro Use Guide

Rat and human hepatocytes were incubated with 20 and 100 microM fipexide for 0, 2 and 6 hours at 30 deg-C. Samples were then quenched with equal volumes of ice-cold acetonitrile and centrifuged at 12000 rpm for 10 min at 4 deg-C. The supernatant was diluted 1:1 with water prior to injection into LC/MS to test whether the catechol metabolite or fipexide could be profiled for protein binding.
