title: The influence of the kappa-agonist bremazocine on ingestive behaviour in mice and rats.
abstract: The effects of bremazocine on drinking and eating behaviour were studied in non-deprived mice and 12 hr food and water deprived rats. In both species, bremazocine (1-8 mg/kg) produced substantial increase in fluid intake (dose-dependent in rats). The concomitant alterations of food intake were less pronounced and opposite: increase in mice, decrease in rats. Morphine (1.25-10.0 mg/kg) invariably inhibited eating and drinking behaviour in mice. The afore-said effects of the kappa-receptor agonist bremazocine are not affected by naloxone which attenuates the effects of the mu-receptor agonist morphine.
