With a few drugs, such as aspirin, … WebSep 1, 2024 · Aspirin and warfarin compete for the same plasma protein binding sites, and thus, coadministration potentiates the effects of the two ( 3, 6 ). A small number of drugs may bind irreversibly to plasma proteins via covalent bonding. As a result, bound drug is not released in response to decreasing plasma or tissue concentrations.
WebElimination Metabolism and excretion are the process that takes place to eliminate drug. Page et al. (2006). Aspirin forms polar metabolites in the liver as it is quickly glucuronidated.
