Abstract
The aim of the present study was to examine the toxic effects of single oral administrations of the antidepressant maprotiline at 150 mg/kg or 300 mg/kg using female Sprague-Dawley rats. Body-weight gain was significantly reduced in the group receiving 300 mg/kg on days 1-5 of the study (P<0.01). A significant reduction in food and water intake was observed on days 1 and 2 of the study (P<0.01) in the 300 mg/kg group and on day 1 in the 150 mg/kg group (P<0.05). There was a significant decrease in nocturnal home cage activity over the first five days of the study in the 300 mg/kg group (P<0.01). A significant hypothermic response was observed in both 150 and 300 mg/kg groups at 1, 2 and 4 hr after dosing (P<0.01), that had returned to control values within 8 hr following administration. This study demonstrates that a multi-parameter approach is appropriate for the investigation of high doses of antidepressants in rodents.
