The aim of this controlled double-blind randomized 3-session cross-over designed study is to evaluate the effects of a single dose of 150 mg and a 14-day repeated dose of 300 mg bupropion (therapeutic dose) on cognitive and executive functions, behaviour and subjective feelings, and some physical parameters after sleep deprivation in 12 trained healthy volunteers (18-35 years old).
Cognitive and executive functions were assessed by reaction times, critical flicker fusion test, Stroop test, digit symbol substitution test, span test and short term recal of pictures, tapping and tracking tests.
Behaviour and subjective effects explored were :
- feelings frequently experienced with psychotropic drugs assessed by ARCI,
- some mood states as tension, depression, anger, vigor, fatigue and confusion assessed by both POMS and Norris visual analogic scales,
- sleep assessed by LSEQ,
- feeding behaviour assessed by food intake during a meal test and self-ratings of appetite and satiety,
Physical parameters were :
- rest and orthostatic blood pressure and heart rate,
- body temperature and weight.
Bupropion was tested versus both placebo and 20 mg methylphenidate as positive control. Each subject received the 3 treatments, sequently randomized, with a 17-day wash-out period between sessions. Each session was organized as follow :
- 2 20-hour hospitalisations consisting in adverse effects review, physical examination, test training, sleep deprivation, drug compliance evaluation, drug dosing and dispensation, and assessments described above,
- 2 visits consisting in adverse effects review, drug compliance evaluation and drug dispensation.
The total duration of participation for the subjects was 106 days.
