  • Beschreibung: <jats:p>We studied the influence of cardiovascular (CV) risk factors, previous CV events, and cotreatments with preventive medicines, on residual platelet thromboxane (TX)B<jats:sub>2</jats:sub> production in 182 patients chronically treated with enteric coated (EC)‐aspirin (100 mg/day). The response to aspirin was also verified by assessing arachidonic acid‐induced platelet aggregation and urinary 11‐dehydro‐TXB<jats:sub>2</jats:sub> levels. Residual serum TXB<jats:sub>2</jats:sub> levels exceeded the upper limit value for an adequate aspirin response in 14% of individuals. This phenomenon was detected at 12 hours after dosing with aspirin. The coadministration of statins (mostly atorvastatin) was an independent predictor of residual serum TXB<jats:sub>2</jats:sub> levels, and the percentage of patients with enhanced values was significantly lower in statin users vs. nonusers. We provide evidence <jats:italic>in vitro</jats:italic> that atorvastatin reduced residual TXB<jats:sub>2</jats:sub> generation by increasing the extent of acetylation of platelet COX‐1 by aspirin. In conclusion, the coadministration of statins may counter the mechanisms associated with reduced bioavailability of aspirin detected in some individuals with CV disease.</jats:p>
