Mode of Action
Aspirin is an analgesic, anti-inflammatory and antipyretic. It inhibits cyclooxygenase, which is responsible for the synthesis of prostaglandin and thromboxane. It also inhibits platelet aggregation.
Interaction
Alcohol, corticosteroids, analgin, phenylbutazone and oxyphenbutazone may increase risk of GI ulceration. Aspirin increases phenytoin levels. May antagonize actions of uricosurics and spironolactone.
Potentially Fatal: May potentiate effects of anticoagulants, methotrexate and oral hypoglycaemics.
