Clinical trials: Platelet Dysfunction
Platelet Dysfunction Due to Drugs
Aspirin Resistance in Trinidad.
Aspirin's beneficial effect is mediated via the inhibition of arachidonic acid (AA) activation of platelets. It is detected by demonstrating a decrease in platelet function and/or a decrease in prostaglandin metabolites.
