Rethinking the ISAR

Those assigned prasugrel received a 60 mg loading dose, followed by a maintenance dose of 10 mg once daily. Stefanie Schüpke at the European Society of Cardiology Congress, Paris, France, September 1, 2019. After one year administer 60 mg twice daily. At 1 year, prasugrel was associated with a 2. As a result, the degree to which study findings can be extended to those undergoing primary medical therapy is limited. Major bleeding rates were similar in both groups. Ticagrelor or Prasugrel in Acute Coronary Syndromes — The Winner Takes It All? Strong inhibitors substantially increase ticagrelor exposure and so increase the risk of adverse events.

In other words, the timing of study drug administration was irrespective of clinical presentation and knowledge of coronary anatomy. Patients assigned ticagrelor received a 180 mg loading dose starting as soon as possible after randomization, followed by a maintenance dose of 90 mg twice daily. Benefit from prasugrel was accomplished without an increase in major bleeding. The reason for this finding is unknown, but irreversible platelet inhibition from prasugrel warrants consideration. Whether ticagrelor or prasugrel is preferred over the other with regard to thrombotic and bleeding risk, however, remained unclear. No formal assessment of drug adherence Non-adherence reported of 0. Stent thrombosis was rare in both groups, but numerically lower with prasugrel.

The hypothesis of this trial was that pretreatment with ticagrelor would translate into a reduction in major adverse ischemic events; however, the opposite finding was observed. This is consistent with a slightly higher rate of drug discontinuation prior to 12 months in the ticagrelor group 15% versus the prasugrel group 12%. The primary composite endpoint of death, myocardial infarction, or stroke at 12 months occurred in 9. If you are enrolled in a state or federally funded prescription insurance program, you may not use this savings card even if you elect to be processed as an uninsured cash-paying patient. Paris, France — 1 Sept 2019: Prasugrel is superior to ticagrelor for reducing ischaemic events in patients with acute coronary syndrome and a planned invasive strategy. Individual costs and benefit design may vary.

Patients who received fibrinolytic therapy within the previous 24 hours or who had a need for chronic oral anticoagulation therapy were excluded. I think this study will surprise a lot of people. The timing of prasugrel initiation was based on clinical presentation. The degree of benefit observed exceeds that seen with clopidogrel versus placebo, which is difficult to explain. Guidelines As of September 2019, no guidelines have been published that reflect the results of this trial. Although the mechanism of improved outcomes with prasugrel requires further investigation, it has been proposed that once daily dosing with prasugrel as opposed to twice daily dosing with ticagrelor may underlie much of the benefit. Definite stent thrombosis was lower with prasugrel as well, although the difference was not statistically significant in the setting of very low rates 0.

Major bleeding was also numerically lower with prasugrel 4. True adherence to trial medication was probably much lower than that reported by the authors. Presented at: European Society of Cardiology Congress; Aug. The European Society of Cardiology brings together health care professionals from more than 150 countries, working to advance cardiovascular medicine and help people lead longer, healthier lives. Definite or probable stent thrombosis occurred in 1. Ticagrelor or prasugrel in patients with acute coronary syndromes.

Prospective, Randomized Trial of Ticagrelor Versus Prasugrel in Patients With Acute Coronary Syndrome

The incidence of the individual components of the primary endpoint in the ticagrelor and prasugrel groups was 4. This offer is not insurance, is restricted to residents of the United States and Puerto Rico, and to patients over 18 years of age. Current treatment guidelines give preference to a potent P2Y12 inhibitor over clopidogrel, but data have been lacking to recommend one particular potent P2Y12 inhibitor over another. Findings were similar among the tested subgroups. AstraZeneca does not endorse any individual Commercial, Medicare Part D, or Medicaid plan or plans. It does not necessarily reflect the opinion of the European Society of Cardiology. A total of 4,018 patients were enrolled from 23 centres in Germany and Italy and randomly allocated to prasugrel or ticagrelor.

Patients assigned to ticagrelor received a loading dose as soon as possible after randomisation. There was no increase in the rate of major bleeding with prasugrel. The increase in anti-ischaemic efficacy with prasugrel was not accompanied by a raised bleeding risk. Ticagrelor versus clopidogrel in patients with acute coronary syndromes. Ticagrelor or Prasugrel in Patients With Acute Coronary Syndromes. Until now, the relative merits of ticagrelor versus prasugrel for the one-year treatment of acute coronary syndrome patients were unknown.
