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 ]
"Platelet inhibition can be demonstrated two hours after a single dose of oral clopidogrel, but the onset of action is slow, so that a loading-dose of 300–600mg is usually administered" needs clarification - if there is detectable action after 2h this is not particularly slow in most circumstances.
Prasugrel is a member of the thienopyridine class of ADP receptor inhibitors, like ticlopidine (trade name Ticlid) and clopidogrel (trade name Plavix). These agents reduce the aggregation ("clumping") of platelets by irreversibly binding to P2Y 12 receptors. Prasugrel inhibits platelet aggregation more rapidly, more consistently, and to a ...
When ticlopidine and clopidogrel were first brought to the market, ticlodipine in 1978 and clopidogrel in 1998, the mechanism of action of these two major antithrombotic drugs was not fully understood. What had been shown was that they were potent inhibitors of ADP-induced platelet aggregation, but the P2Y 12 receptor had not been identified.
Available antiplatelet drugs have delayed onset and offset of action. [10] Since cangrelor's effects are immediate and quickly reversed, it is a more desirable drug for elective treatment of stenotic coronary arteries, high risk acute coronary syndromes treated with immediate coronary stenting, and for bridging those surgery patients who ...
As the year of 2024 wraps up, here's a list of travel trends in America that consumed folks on social media, including "gate lice," "seat squatters" and "sleep divorce."
A decades-old cosmetic procedure called mesotherapy, which involves injecting unregulated mixtures of vitamins and drugs under the skin to reduce under-eye bags, is regaining popularity in the US.
In Japanese people, concentrations are 40% higher than in Caucasians, or 20% after body weight correction. The drug has not been tested in people with severe hepatic impairment. [24] [34] Consistently with its reversible mode of action, ticagrelor is known to act faster and shorter than clopidogrel. [35]
