Fluparoxan: A Comprehensive Review of its Discovery, Adrenergic and CNS Activity and Treatment of Cognitive Dysfunction in Central Neurodegenerative Diseases

Abstract

Background: The design, medicinal chemistry, pharmacokinetics and development of the highly selective α2-adrenoceptor antagonist fluparoxan are reviewed.

Method: The drug's activity and selectivity in vitro, its efficacy in animals and its excellent oral pharmacokinetics and central α2-adrenoceptor antagonist activity in man, are evaluated as well as its ability to increase extracellular levels of noradrenaline, dopamine and acetylcholine in vivo.

Conclusion: Furthermore, its potential for the treatment of central neurodegenerative diseases is highlighted, in particular its improvement of cognitive dysfunction in schizophrenia and in models of Alzheimer's disease.

Keywords: Alzheimer's; depression; fluparoxan; schizophrenia; α2-adrenoceptor antagonist.
