Epoetin alfa has a potent anxiolytic effect on naive female rats

Abstract

BackgroundEpoetin alfa is a derivative of the erythropoietin hormone. This study aims to investigate the epoetin alfa effect on anxiety-like behaviors.MethodsAdult female Wistar Albino rats were divided into Control (n = 8), 1000 U Epoetien alfa, and 2000 U Epoetien alpha. Epoetin alfa was administered intraperitoneally once a week for 4 weeks. The animals were then subjected to open field test, elevated plus maze, light-dark box, and the behaviors were video recorded.ResultsEpoetin alfa significantly reduced anxiety-like behaviors in both low- and high-dose groups in a dose-independent manner. This anxiolytic effect was seen in all three anxiety tests. Further, exploratory behaviors such as unsupported rearing and head-dipping behaviors increased with the application of Epoetin alfa. This protocol did not alter locomotor activity.ConclusionThe present study found beneficial effects of epoetin alfa on behaviors. Further studies on the effect of derivatives of erythropoietin hormone on anxiety-like behaviors are needed.
