Arms of the Study
Arm 1
Arm 2
Experimental
Active Comparator
Chewed ticagrelor
Swallowed ticagrelor
Ticagrelor pills. The 180 mg loading dose will be administered as soon as possible by investigation staff after a baseline VerifyNow measurement and after signed informed consent. Patients will be asked to chew, but not to swallow, during at least 40 seconds in presence of investigation staff. Drug: ticagrelor (Brilinta) 90 mg tablets, 2 tablets chewed
Ticagrelor integral tablet. The 180 mg loading dose will be administered as soon as possible by investigation staff after a baseline VerifyNow measurement is drawn. Patients will swallow the loading dose followed by 25-40 ml of water. Drug: ticagrelor (Brilinta) 90 mg tableta, 2 tablets swallowed
