Lysine acetylsalicylate, also known as aspirin DL-lysine or lysine aspirin, is a more soluble form of acetylsalicylic acid (aspirin). As with aspirin itself, it is a nonsteroidal anti-inflammatory drug (NSAID) with analgesic, anti-inflammatory, antithrombotic and antipyretic properties. [ 1 ]
The US Food and Drug Administration recommends aspirin (or aspirin-containing products) should not be given to anyone under the age of 12 who has a fever, [192] and the UK National Health Service recommends children who are under 16 years of age should not take aspirin, unless it is on the advice of a doctor.
NSAIDs aside from (low-dose) aspirin are associated with a doubled risk of heart failure in people without a history of cardiac disease. [66] In people with such a history, use of NSAIDs (aside from low-dose aspirin) was associated with a more than 10-fold increase in heart failure. [67]
Aspirin helps prevent blood clots from forming, which is the leading cause of heart attack and stroke, but the drug also carries a risk of bleeding. That risk can outweigh aspirin’s benefits in ...
Aspirin-exacerbated respiratory disease (AERD), also called NSAID-exacerbated respiratory disease (N-ERD) or historically aspirin-induced asthma and Samter's Triad, is a long-term disease defined by three simultaneous symptoms: asthma, chronic rhinosinusitis with nasal polyps, and intolerance of aspirin and other nonsteroidal anti-inflammatory drugs (NSAIDs).
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]
One meta-analysis indicated that ibuprofen is more effective than acetaminophen in children at similar doses when both are given alone. [16] Due to concerns about Reye syndrome, it is recommended that aspirin and combination products that contain aspirin not be given to children or teenagers during episodes of fever-causing illnesses. [17] [18]
[8] [9] About 5–10% of asthmatics have aspirin hypersensitivity, but dietary salicylates have been shown not to contribute to this. The reactions in AERD (Samter's triad) are due to inhibition of the COX-1 enzyme by aspirin, as well as other NSAIDs that are not salicylates. Dietary salicylates have not been shown to significantly affect COX-1 ...
