  • Title: Mazindol: anorectic and behavioral effects in female rats.
    Author: Mattei R, Carlini EA.
    Journal: Arch Int Pharmacodyn Ther; 1995; 330(3):279-87. PubMed ID: 8836447.
    Abstract:
    The anorectic and behavioral effects of mazindol (2.5, 5 and 10 mg/kg) were determined. The experiments comprized acute and chronic administration to female rats, and the effects were compared with those produced by 2.5 mg/kg of methamphetamine. The following evaluation parameters were considered: food intake, body weight, motor activity, and stereotyped behavior. Acute administration of the three doses of mazindol, as well as of the methamphetamine dose, decreased food intake. Administered chronically to female rats, mazindol (5 and 10 mg/kg) and methamphetamine induced loss of body weight during the first fifteen days. However, weight was subsequently regained by the animals, indicating development of tolerance. Mazindol (10 mg/kg) and methamphetamine produced an increase in motor activity. This increase was, however, not observed after chronic treatment, suggesting development of tolerance. Additionally, mazindol induced noticeable dose-dependent effects, involving stereotyped behavior (sniffing, continuous licking, false bites), similar to those produced by methamphetamine. Verticalization, however, was only observed after administration of 2.5 and 5 mg/kg of mazindol, and was absent after administration of the higher dose of mazindol as well as of methamphetamine. Finally, it should be stressed that features of stereotyped behavior induced by both drugs, such as licking, false bites, sniffing and verticalization, were very similar.
