“Different doses of caffeine alone generally produced dose-related increases in caffeine-appropriate responding; when administered concomitantly with triazolam , the caffeine dose-effect curve shifted significantly to the right.”
“ Triazolam and caffeine , but not buspirone and caffeine, generally produced significant interactions on several self-report and psychomotor performance measures.”
“ Triazolam blocked the discriminative effects of the caffeine training dose in a dose-related manner in five out of six subjects; whereas buspirone did so in only one out of four subjects.”
