Clopidogrel, sold under the brand name Plavix among others, is an antiplatelet medication used to reduce the risk of heart disease and stroke in those at high risk. [10] It is also used together with aspirin in heart attacks and following the placement of a coronary artery stent (dual antiplatelet therapy). [10] It is taken by mouth. [10]
In patients with truly time-sensitive disease (defined in the 2014 ACC/AHA guidelines as needing to proceed in 2–6 weeks), DAPT can be stopped 3 (three) months (90 days) after a coronary stent is placed if postponing surgery any longer would result in significant morbidity.
Both aspirin and clopidogrel may be useful in the first few weeks after a minor stroke or high-risk TIA. [128] Clopidogrel has less side effects than ticlopidine. [ 127 ] Dipyridamole can be added to aspirin therapy to provide a small additional benefit, even though headache is a common side effect. [ 129 ]
In the US, ticagrelor is indicated to reduce the risk of stroke in people with acute ischemic stroke or high-risk transient ischemic attack. [5]In the EU, ticagrelor, co-administered with acetylsalicylic acid (aspirin), is indicated for the prevention of atherothrombotic events in adults with acute coronary syndromes or a history of myocardial infarction and a high risk of developing an ...
Metabolism of ticlopidine, clopidogrel and prasugrel to an active metabolite. Clopidogrel is a prodrug that is metabolized by two pathways. In one of the pathway most of the dose of clopidogrel (85%) is hydrolyzed by esterases to an inactive carboxylic acid derivate and rapidly cleared via glucoridination followed by renal excretion.
[18] [19] Unlike clopidogrel, prasugrel is effective in most individual with the exception in patients over the age of 75, weight under 60 kg, and patients with a history of stroke or TIA due to increased risk of bleeding, [20] [4] although several cases have been reported of decreased responsiveness to prasugrel. [21]
A new survey found that 1 in 5 adults “who say they have no personal or family history of heart attack or stroke,” reported “routinely” taking a low-dose aspirin
We undertook a post-hoc analysis of data from the ROCKET AF (Rivaroxaban Once-Daily, Oral, Direct Factor Xa Inhibition Compared With Vitamin K Antagonism for Prevention of Stroke and Embolism Trial in Atrial Fibrillation, n = 14,624) for stroke or non-CNS embolism within 30 days after temporary interruptions of 3 days or more, early permanent ...
