Due to reported severe adverse effects of ticlopidine second and third-thienopyridines, clopidogrel and prasugrel, were developed. [ 5 ] 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.
Targeted covalent inhibitors (TCIs) or Targeted covalent drugs are rationally designed inhibitors that bind and then bond to their target proteins.These inhibitors possess a bond-forming functional group of low chemical reactivity that, following binding to the target protein, is positioned to react rapidly with a proximate nucleophilic residue at the target site to form a bond.
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 ]
Many drug interactions are due to alterations in drug metabolism. [12] Further, human drug-metabolizing enzymes are typically activated through the engagement of nuclear receptors. [12] One notable system involved in metabolic drug interactions is the enzyme system comprising the cytochrome P450 oxidases.
Meloxicam has been shown, especially at low therapeutic doses, to selectively inhibit COX-2 over COX-1. [8] Meloxicam concentrations in synovial fluid range from 40% to 50% of those in plasma. The free fraction in synovial fluid is 2.5 times higher than in plasma, due to the lower albumin content in synovial fluid compared to plasma.
[55] [57] An interaction between PPIs and the metabolism of the platelet inhibitor clopidogrel is known and this drug is also often used in people with cardiac disease. [58] [59] [22] There are associations with an increased risk of stroke, but this appears to be more likely to occur in people who already have an elevated risk. [60]
