There has been an increase in the consumption of energy drinks in the last decade which raises a concern
regarding its safety. Glucose improves information processing and cognition. But research on only glucose
containing drink is lacking. In the present study, we evaluated the effect of Red Bull, a caffeine containing energy
drink and Glucon D on visual and auditory reaction time in medical students. A total of 30 students,15 boys and 15
girls, in the age group 18 to 22 yrs were recruited for the study after taking approval from the Institutional Ethical
Committee. At the beginning, a baseline record of pulse, blood pressure, ART and VRT were taken for all students.
The students were given Red Bull after an interval of 30 minutes and the same fifteen students were given Glucon D
after an interval of 5 days. All readings were taken between 10-12 a.m. On comparing the effect of Red Bull on
either sex, there was no significant difference. On comparing the effect of the two energy drinks, the p value between
the effect of Red Bull and Glucon D on ART was 0.457 and on VRT was 0.314.Both were not statistically significant.
There was a significant increase in pulse rate with Red Bull (P=0.036). The mean DBP increased marginally with
Red Bull which was not significant (P=0.835).
Key words: Audiovisual Reaction time, Caffeine, Energy Drink, Glucon D, Red bull.
