Effect of mazindol on feeding behaviour and on noradrenergic function of various parts of the rat brain.
The effect of mazindol on feeding behaviour was investigated in rats fasted for 24 hours. They were then given mazindol i.p. and placed in a new environment. The effect of the drug on the disappearance of 3H-noradrenaline (3H-NA) from various parts of the brain after injection into the cerebral ventricles was also investigated. Mazindol was more potent in suppressing feeding behaviour than in reducing food intake, indicating that a number of aspects of feeding behaviour may be more sensitive indices of the anorectic effect of a drug than food intake per se. Mazindol, in a dose of 30 mg/kg, accelerated the disappearance of 3H-NA from the medial hypothalamus but not from other areas of the brain, suggesting that the drug has a locus-specific action on cerebral noradrenaline metabolism.
