At 2 hours post administration
Secondary outcome [1] 1377 0
To determine whether decreased CYP2C19 function correlates with markers of disease severity as determined by circulating inflammatory cytokines (IL1, IL6 & TNF-α) and a marker of acute phase response, C-reactive protein.
Timepoint [1] 1377 0
