Ticagrelor (Brilique(®)) is an orally administered P2Y12 inhibitor. A long-term (maintenance) regimen of ticagrelor 60 mg twice daily is indicated in the EU for coadministration with low-dose aspirin 75-150 mg/day for the secondary prevention of atherothrombotic events in high-risk patients with a history of myocardial infarction (MI) of at least 1 year. Approval is based on the results of the PEGASUS-TIMI 54 trial that compared ticagrelor with placebo (in conjunction with low-dose aspirin) in stable patients who had had a spontaneous MI 1-3 years prior to enrolment and were at high risk of atherothrombotic events...

Portal vein thrombosis (PVT) is common in patients with cirrhosis undergoing transjugular intrahepatic portosystemic shunt (TIPS). This study had 3-fold aims: to assess risk factors for PVT; to determine the efficacy of anticoagulant therapy; to investigate the impact of PVT on clinical outcomes in TIPS-treated cirrhosis.Between June 2012 and February 2016, 126 TIPS-treated patients with cirrhosis were enrolled and studied prospectively. Enrolled patients were screened for PVT before TIPS and at 3, 6, 12, and 24 months post-TIPS...

Aims: Dual platelet inhibition using anti-P2Y12 drugs and aspirin is the standard of care in patients after percutaneous coronary interventions (PCI). Prasugrel and ticagrelor have been shown to be more potent than clopidogrel with less high on-treatment platelet reactivity. Whether differences in long-term adherence to these drugs can partly explain different antiplatelet efficacy has not been studied so far. The objective was to compare the long-term P2Y12 receptor inhibition and drug adherence to different anti-P2Y12 drugs, and to assess the impact of adherence on the pharmacodynamic effect...

BACKGROUND: Prior Studies have suggested better outcomes in smokers compared with nonsmokers receiving clopidogrel ("smoker's paradox"). The impact of a more intensive clopidogrel regimen on ischemic and bleeding risks in smokers with acute coronary syndromes requiring percutaneous coronary interventions remains unclear. METHODS AND RESULTS: We analyzed 17 263 acute coronary syndrome patients undergoing percutaneous coronary intervention from the CURRENT-OASIS 7 (Clopidogrel and Aspirin Optimal Dose Usage to Reduce Recurrent Events-Seventh Organization to Assess Strategies in Ischemic Symptoms) trial, which compared double-dose (600 mg day 1;150 mg days 2-7; then 75 mg daily) versus standard-dose (300 mg day 1; then 75 mg daily) clopidogrel in acute coronary syndrome patients...

Essential thrombocythemia (ET) and polycythemia vera (PV) are myeloproliferative neoplasms (MPN) with an increased risk of arterial and venous thrombosis. Aspirin is recommended to reduce this risk, but resistance to antiplatelet therapy seems to hamper its efficacy in some patients. We have previously shown that multiple electrode aggregometry (MEA) was a valuable tool to assess aspirin resistance in MPN. In this study, MEA was used to assess the reduction in aspirin resistance after bi-daily (BID) aspirin intake or cytoreduction...

Low-dose aspirin (75 mg or 81 mg) is considered to be the lowest effective dose for cardiovascular protection, however, the use of enteric preparations has created a source of variability in bioavailability. As part of regulatory requirements we carried out bioequivalence tests for two 75 mg enteric-coated aspirin preparations (Caprin and Protek) using Nu-Seals 75 mg aspirin as the comparator. The primary endpoint was serum thromboxane levels after 14 days of treatment. Protek failed to meet bioequivalence, as it was significantly less effective than Nu-Seals...

BACKGROUND: Evidence from clinical trial populations suggests low-dose aspirin reduces the risk of colorectal cancer (CRC). Part of this reduction in risk might be due to protection against metastatic disease. METHODS: We investigated the risk of CRC among new-users of low-dose aspirin (75-300 mg), including risk by stage at diagnosis. Using The Health Improvement Network, we conducted a cohort study with nested case-control analysis. Two cohorts (N = 170,336 each) aged 40-89 years from 2000 to 2009 and free of cancer were identified: i) new-users of low-dose aspirin, ii) non-users of low-dose aspirin, at start of follow-up, matched by age, sex and previous primary care practitioner visits...

BACKGROUND Clopidogrel is commonly used in the prevention and treatment of cardiovascular events. However, despite clopidogrel treatment, some patients experience recurrent ischemic events. CASE REPORT We present the case of a 58-year-old man with polycythemia vera and concomitant thrombocytosis who suffered 6 episodes of cerebral infarctions and 1 myocardial infarction, despite treatment with clopidogrel. Following his last ischemic event, the antiplatelet therapy was intensified from initially clopidogrel monotherapy to dual antiplatelet therapy with aspirin 75 mg once daily and ticagrelor 90 mg twice daily...

REVIEW
A Ross Naylor
There is a paucity of high-quality evidence regarding what constitutes "optimal medical therapy" for the purposes of reducing morbidity/mortality after carotid endarterectomy (CEA). All patients should be prescribed antiplatelet therapy. Low-dose aspirin (75 to 325 mg) should be continued throughout the perioperative period and there is no evidence that higher doses confer additional benefit. There is emerging evidence that early implementation of dual antiplatelet therapy in recently symptomatic patients (aspirin 75 mg plus clopidogrel 75 mg) can reduce recurrent cerebral events before CEA and that dual antiplatelet therapy will significantly reduce stroke due to early postoperative carotid thrombosis...
