The weight gain and hyperphagia induced by chronic administration of s
ulpiride in female rats were not prevented by the concomitant administ
ration of an extra source of sodium. In addition, serum sodium levels
were not affected, but potassium levels were significantly reduced by
sulpiride administered for 1 week. These results suggest that sulpirid
e-induced obesity in rats is not related to sodium imbalance. The mech
anism for the decrease in serum potassium levels and its relation with
sulpiride-induced weight gain warrant further investigation.
