“In these experiments, responses to AA (Fig. 1A) were found to be completely inhibited by ticagrelor at the higher two concentrations (representing ∼IC50 and IC90 for ADP-induced aggregation) without the need for aspirin.”
“ Ticagrelor and PAM, as well as aspirin, also produced complete, concentration-dependent inhibitions of platelet aggregations induced by AA (Fig. S3; log IC50 values for inhibition of aggregation to 1 mmol L−1 AA: ticagrelor, −6.88; PAM, −6.00; aspirin, −5.20).”
