ABSTRACT

PURPOSE:

To compare the effects of the antidepressant drugs duloxetine and fluoxetine on depressive behaviors in rodents.

METHODS:

Eighteen male Wistar rats were given systemic injections of duloxetine, fluoxetine, or saline prior to a Forced Swimming Test (FST). Immobility and number of stops were measured.

RESULTS:

Rats given injections of fluoxetine displayed significantly less immobility (p = 0.02) and fewer stops than the control group (p = 0.003). Duloxetine significanlty reduced the number of stops (p = 0.003), but did not effect immobility (p = 0.48).

CONCLUSION:

Duloxetine and fluoxetine reduced depressive behaviors in the Forced FST. However, our findings suggest that fluoxetine is more effective than duloxetine.
RESUMO

OBJETIVO:

Comparar o efeito antidepressivo da droga cloridrato de duloxetina com a fluoxetina.

MÉTODOS:

O teste do nado forçado, teste comportamental que avalia a atividade antidepressiva em ratos, foi utilizado em 18 ratos Wistar, machos adultos, divididos em três grupos iguais duloxetina, fluoxetina e controle.

RESULTADOS:

Os dados do teste do nado forçado foram analisados pelo teste One-way ANOVA, Mann Whitney e Kruskall-Wallis.Houve diferença significativa (p = 0,003) entre o número de paradas dos grupos duloxetina e fluoxetina e o grupo controle.

CONCLUSÃO:

A duloxetina e a fluoxetina tiveram frequência de paradas similares. A fluoxetina mostrou ser mais efetiva que a duloxetina no teste do nado forçado em ratos.
