Antithrombotic in myocardial infarction Other NSAIDs are preffered for anti- inflammaotry actiona dn analgesua in musculo- skeletal conditions
Aspirin Adverse effects
GI disturbances Gastric bleeding Salicyclism Allergic reactions Renal toxicity
What effects does Asprin have?
analgesic, antipyretic, and anti-inflammatory effect
how is Aspirn able to have analgesic, antipyretic, and anti-inflammatory effects
due to actions by both the acetyl and the salicylate portions of the intact molecule as well as by the active salicylate metabolite
what does Acetylsalicylic acid do
directly and irreversibly inhibits the activity of both types of cyclooxygenase (COX-1 and COX-2) to decrease the formation of precursors of prostaglandins and thromboxanes from arachidonic acid
what is a result of Acetylsalicylic acid’s analgesic and anti-inflammatory mechanisms
antirheumatic actions
what happens during the . Irreversible inhibition of COX
prevention the formation of the aggregating agent thromboxane A2 in platelets. Platelets cannot produce more COX enzyme
how long does the effects of aspirin percist?
for the life of the exposed platelets (7-10 days).
