Plasma perindopril concentration in combination with Chungsinoryungsan (CSORS) within 5 min. The combination group of rats received oral co-administration of perindopril with CSORS within 5 min (open circles, n=5) and the corresponding control received perindopril with distilled water (closed circles, n=5). The plasma samples were assessed at 0.5, 1, 2, 3, 4, 6, 8 and 24 h post-administration. All the data represent average values (ng/ml) ± SEM. ^*P<0.01.
