A more popular classification, however, is based on structural differences and similarities . In: Yu TF, Gutman AB (1959): Study of the paradoxical effects of salicylate in low, intermediate, and high dosage on the renal mechanisms of excretion of urate in man. There are two types of cyclooxygenase; COX-1 and COX-2. and its Licensors Mechanism of action. Ibuprofen inhibits both COX-1 and COX-2. Vane JR. Inhibition of prostaglandin synthesis as a mechanism of action for aspirin-like drugs. The differences in activity between aspirin and salicylic acid are thought to be due to the acetyl group on the aspirin molecule. Aspirin Aspirin is synthesized by the acetylation of salicylic acid using acetic anhydride or acetyl chloride. CONTINUED… 1) Substitution on carboxyl groups may affect the potency and toxicity. Paradoxically, much larger doses of aspirin (>3 gm/day; or over ten 325 mg tablets/day) have been observed to be As illustrated in Figure 3, non-aspirin NSAIDs can interfere with aspirin's ability to gain access to its COX-1 binding site by steric interference(2 drugs can't occupy the same active site at the same time), thus reducing aspirin's antiplatelet effects when the two drug types are taken concomitantly. 8. Figure 1. History, Mechanism of action, Adverse affects Acetylsalicylic acid, commonly known as aspirin, is the most popular therapeutic drug in the world. Mechanism of action. 1971 Jun 23; 231 (25):232–235. Ann Rheum Dis 73(2):385-390. doi: 10.1136/annrheumdis-2012-202589.Low doses of aspirin selectively inhibit COX-1. Acetylsalicylic acid, commonly known as aspirin, is the most popular therapeutic drug in the world. When aspirin is in the body it targets the enzyme cyclooxygenase, where it irreversibly prevents the inactivating platelet cyclo-oxygenase. Aspirin Indications. Mechanism of Action: aspirin (acetylsalicylic acid) acetylates a serine residue in the active sites for both COX-1 & COX-2, which irreversibly inhibits these enzymes (as illustrated for COX-1 in Figure 1). Aspirin is rapidly hydrolyzed primarily in the liver to salicylic acid, which is conjugated with glycine (forming salicyluric acid) and glucuronic acid and excreted largely in the urine As a result of rapid hydrolysis, plasma concentrations of aspirin are always low and rarely exceed 20 mcg/ml at ordinary therapeutic doses The peak salicylate level for uncoated aspirin occurs in about 2 hours; however with enteric coated aspirin tablets this is delayed. Broadly, NSAIDs are grouped into aspirin and nonaspirin NSAIDs. Mechanism of Action: Aspirin is a more potent inhibitor of both prostaglandin synthesis and platelet aggregation than other salicylic acid derivatives. Circulation. Arthritis Rheum 43(1):103-108. It is an analgesic (pain-killing), antipyretic (fever-reducing), and anti-inflammatory sold without a prescription as tablets, capsules, powders, or suppositories. Mechanism Of Action as Analgesic : 7. Kiefer, D.M. Studies in man indicate that salicylate is excreted in the urine as free salicylic acid (10%), salicyluric acid (75%), salicylic phenolic (10%) and acyl (5%) glucuronides and gentisic acid (<1%). Hyperpnea (increased depth & rate of respiration) through a direct effect on the medulla resulting in a Body temperature may be elevated due to uncoupling of oxidative phosphorylation, potentially resulting in Potassium moves from the intracellular space to the extracellular space Aspirin may contribute to increasing bleeding time by decreasing prothrombin in the plasma Large doses have a hypoglycemic action that can enhance the effect of oral hypoglycemic drugs and affect the diabetic's insulin requirements. However, in the light of newly identified mechanisms of action of aspirin, other immunomodulatory, anti-inflammatory, and … Catella-Lawson F et al (2001): Cyclooxygenase inhibitors and the antiplatelet effects of aspirin. Cipollone F et al (1997): Differential suppression of thromboxane biosynthesis by indobufen and aspirin in patients with unstable angina. Flomenbaum NE (2006): Salicylates (Chapter 35). Acute myocardial infarction or myocardial ischemia. Ibuprofen is an NSAID which is believed to work through inhibition of cyclooxygenase (COX), thus inhibiting prostaglandin synthesis.
