“Citalopram alone produced predominantly saline-appropriate responding, but when administered before cocaine, citalopram dose-dependently shifted the cocaine dose-response curve leftward.”
“ Citalopram , however, attenuated the discriminative-stimulus effects of cocaine in squirrel monkeys trained to discriminate cocaine from saline, though it enhanced the discriminative-stimulus effects of a low dose of cocaine in rats trained to discriminate high and low doses of the drug.”
