In rats, a weighed amount of food (standard laboratory pellets), water, and kaolin was given to animals, and the weight consumed (evaluated as the difference between the original amount and the one left in the cages, including spillage) was measured before and 24, 48, 72, and 96 h after treatments. Metoclopramide (5 mg kg−1), used as reference drug, was suspended in 1% carboxymethylcellulose sodium salt and orally (p.o.) administered. Control animals were treated with vehicles.
