Abstract:

Pharmacokinetic and metabolomic methods were employed to investigate the influence of caffeine on the sedative effects of promethazine. First, a space flight vigilance tasks simulation system and Standford sleepiness scale(SSS) were used to compare the effect of single administration of promethazine and combination administration with caffeine on the cognitive function of volunteers. Then software named Kinetica was used to calculate some of the important pharmacokinetic parameters of promethazine before and after the combination. And the possible influencing factors were discussed. Finally, a metabolomic method was applied to identify the potential biomarkers between two groups. The results suggest that caffeine could confront the sedative effects of promethazine and so improve the decreased cognitive function, which might be induced by the accelerated metabolism of promethazine and the altered dopamine, norepinephrine and epinephrine related pathways. This study provides a new approach for the research of combination administration of promethazine and caffeine.
