The antipyretic actions of acetaminophen are likely attributed to direct action on heat-regulating centers in the brain, resulting in peripheral vasodilation, sweating, and loss of body heat.24 The exact mechanism of action of this drug is not fully understood at this time, but future research may contribute to deeper knowledge.24, Acetaminophen has 88% oral bioavailability and reaches its highest plasma concentration 90 minutes after ingestion.9 As opposed to the salicylate drug class, acetaminophen does not disrupt tubular secretion of uric acid and does not affect acid-base balance if taken at the recommended doses.23 Acetaminophen does not disrupt hemostasis and does not have inhibitory activities against platelet aggregation.Label,23 Allergic reactions are rare occurrences following acetaminophen use.23, According to its FDA labeling, acetaminophen's exact mechanism of action has not been fully establishedLabel - despite this, it is often categorized alongside NSAIDs (nonsteroidal anti-inflammatory drugs) due to its ability to inhibit the cyclooxygenase (COX) pathways.14 It is thought to exert central actions which ultimately lead to the alleviation of pain symptoms.14, One theory is that acetaminophen increases the pain threshold by inhibiting two isoforms of cyclooxygenase, COX-1 and COX-2, which are involved in prostaglandin (PG) synthesis.
