Doctors used to recommend taking a low-dose aspirin daily, but this has changed in recent years. ... we would recommend 325 milligrams,” he says. “The dose is really dependent on the patient ...
The acutely toxic dose of aspirin is generally considered greater than 150 mg per kg of body mass. [12] Moderate toxicity occurs at doses up to 300 mg/kg, severe toxicity occurs between 300 and 500 mg/kg, and a potentially lethal dose is greater than 500 mg/kg. [ 13 ]
Aspirin acts as an acetylating agent where an acetyl group is covalently attached to a serine residue in the active site of the COX enzyme. [1] This makes aspirin different from other NSAIDs (such as diclofenac and ibuprofen), which are reversible inhibitors; aspirin creates an allosteric change in the structure of the COX enzyme. [2]
Oral administration can be easier and less painful than other routes of administration, such as injection.

In cases where ICH already has occurred, aspirin use results in higher mortality, with a dose of about 250 mg per day resulting in a relative risk of death within three months after the ICH around 2.5 (95% confidence interval 1.3 to 4.6). [219] Aspirin and other NSAIDs can cause abnormally high blood levels of potassium by inducing a ...
