Abstract

Introduction: Fluoxetine is a prototype drug of Selective Serotonin Reuptake Inhibitors. Its active demethylated metabolite has a half life of 7-10 d. Fluoxetine is used to treat depression and is also prescribed in premature ejaculation.

Aim: In the present study dose and duration dependent effects of Fluoxetine on histology of seminal vesicle of the albino rats were observed.

Materials and methods: The present study was conducted on 36 adult male albino rats. Fluoxetine was administered intraperitoneally for 2 wk, 4 wk and 12 wk with mild (10mg/kg/day), moderate (20mg/kg/day) and severe doses (40mg/kg/day). Histological slides of Seminal vesicle were prepared and stained with Hematoxylin and Eosin stain.

Results: On examination through the light microscope, the proliferation of primary, secondary and tertiary villi, increased crypt/alveoli, increased thickness of lamina propria, decreased epithelial cell height, metaplasia, changes in the amount of luminal eosinophilic secretory material in the form of scanty secretion in lumen of seminal vesicle.

Conclusion: Low doses for long duration and high doses for short duration of Fluoxetine produce histological changes in seminal vesicle of albino rats.
