While antidepressants are widely prescribed to humans for the treatment of anxiety, the results achieved with animal anxiety models are conflicting. The experimental procedure and the prior test history of the animals are critical parameters that are largely susceptible to influence the results and their interpretation. We compared the effect of 5 mg fluoxetine administered to six groups of rats subjected to the psychopharmacological test of the elevated plus-maze, under experimental conditions designed to demonstrate the effect of handling and one daily injection on the response to fluoxetine. The results show that for animals with the same recent experience, fluoxetine, when administered once or over a period of 15 days, induces anxiogenic-like behaviour. On the other hand, our results also show that stressful handling has an anxiolytic-like effect modulating the anxiogenic-like effect of fluoxetine, without eliminating it altogether.
