After baseline platelet testing (Multiplate Analyzer and VerifyNow), cardiovascular disease patients (n=20; 56.9±7.9 years; 65% men; 75% diabetic) received dual antiplatelet therapy as a single loading dose (ticagrelor 180 mg plus aspirin 325 mg) and as daily/maintenance treatment for 5 to 7 days (maintenance therapy: ticagrelor 90 mg BID plus aspirin 81 mg QD).
Blood samples from patients with cardiovascular disease (n = 30) taking no anticoagulant or antiplatelet medication except aspirin were incubated with dronedarone's active metabolite (SR35021A) at 66 ng/ml (am-L) and 119 ng/ml (am-H), i.e., minimum and maximum mean C<sub>max</sub> reported after repeated 400 mg BID dosing.
