4. Fig. 3
Inhibition of ADP-induced aggregation by ARMX, A3P5P and their combination before and after clopidogrel treatment. Platelet aggregation was induced with 5 µmol/L ADP. Platelet activation was inhibited by ARMX (AR-C69931MX, 100 nmol/L), A3P5P (adenosine 3,5 diphosphate, 200 µmol/L) and the combination of ARMX and A3P5P. Dark bars indicate the in vitro inhibition of platelet aggregation. The grey bars indicate combined inhibition of in vitro agents and in vivo clopidogrel. Results are given in means and 95% confidence intervals. On top of clopidogrel treatment ADP-induced platelet aggregation can be further inhibited by in vitro P2Y12- and P2Y1- receptor antagonists. ⁎=P<0.05, ns. = not significant.
