Aspirin, or acetylsalicylic acid, is the "prototypical analgesic used in the treatment of mild to moderate pain. It has anti-inflammatory and antipyretic properties and acts as an inhibitor of cyclooxygenase which results in the inhibition of the biosynthesis of prostaglandins. Specifically, it inactivates the enzyme prostaglandin synthase by acetylating its terminal amino group. Aspirin also inhibits platelet aggregation and is used in the prevention of arterial and venous thrombosis."[1] Aspirin is a non-steroidal anti-inflammatory agent, often abbreviated as NSAID.
Aspirin resistance may cause susceptibility to cardiovascular morbidity.[2]
Aspirin resistance
Individuals in whom platelet function assays demonstrate resistance to aspirin are less likely to have cardiovascular protection from aspirin or other antiplatelet treatments.accompanied by rhinorrhea[3] As many as 28% of patients are resistant to aspirin.[4]
Apparent resistance may be due to inadequate patient compliance, especially in the setting of polypharmacy.[5]
Asthma, Nasal Polyps, and Aspirin Intolerance
Among patients with asthma, 10% to 20% may have bronchoconstriction accompanied by rhinorrhea.[6]
Adverse effects
Gastrointestinal hemorrhage
The gastrointestinal tract is the most common site of bleeding from aspirin.[7]
Intracranial hemorrhage
This may especially occur if the systolic blood pressure is above 130 or 145 mm Hg.[8]
