In the ATLANTIC trial (3) prehospital administration was compared to in-hospital (catheterization laboratory) administration of ticagrelor. The trial indicated that ticagrelor could safely be administered in the ambulance, although there was no apparent effect on Thrombolysis in Myocardial Infarction (TIMI) flow in the culprit coronary artery and no effect on ST-segment resolution in the ECG. However, the median time difference between ticagrelor administration in the two groups was only 31 minutes. This might not leave enough time for adequate platelet inhibition in the prehospital group.
