Acetaminophen - StatPearls - NCBI Bookshelf
Jan 11, 2024 · Mechanism of Action. Acetaminophen is one of the most widely used over-the-counter analgesic and antipyretic medications. Although the exact mechanism of action of the drug remains unclear, it is historically categorized along with nonsteroidal anti-inflammatory drugs (NSAIDs) due to its inhibition of the cyclooxygenase (COX) pathways.
Mechanism of action of paracetamol - PubMed
Paracetamol is a weak inhibitor of PG synthesis of COX-1 and COX-2 in broken cell systems, but, by contrast, therapeutic concentrations of paracetamol inhibit PG synthesis in intact cells in vitro when the levels of the substrate arachidonic acid are low (less than about 5 mumol/L).
Paracetamol (Acetaminophen): mechanisms of action
Sep 2, 2008 · Paracetamol has a central analgesic effect that is mediated through activation of descending serotonergic pathways. Debate exists about its primary site of action, which may be inhibition of prostaglandin (PG) synthesis or through an …
Paracetamol: mechanisms and updates - Oxford Academic
Oct 10, 2013 · Paracetamol is an effective analgesic, especially when administered i.v., useful in a broad range of clinical conditions. Its mechanism of action is yet to be fully determined, and is likely to involve a number of pain pathways.
Paracetamol (Acetaminophen): mechanisms of action - PubMed
Paracetamol has a central analgesic effect that is mediated through activation of descending serotonergic pathways. Debate exists about its primary site of action, which may be inhibition of prostaglandin (PG) synthesis or through an active metabolite influencing cannabinoid receptors.
Paracetamol: mechanism of action, applications and safety ...
The mechanism of action is complex and includes the effects of both the peripheral (COX inhibition), and central (COX, serotonergic descending neuronal pathway, L-arginine/NO pathway, cannabinoid system) antinociception processes and "redox" mechanism.
Paracetamol (acetaminophen): A familiar drug with an ...
One of the key observations that demonstrate a central mechanism of the hypothermic action of paracetamol is the induction of hypothermia with intracerebroventricularly administered paracetamol [131,161].
Paracetamol has a central analgesic effect that is mediated through activation of descending serotonergic pathways. Debate exists about its primary site of action, which may be inhibition of prostaglandin (PG) synthesis or through an active metabolite influencing cannabi-noid receptors.

However, the mechanism of action of paracetamol remains to be determined; pathways gaining credence include the serotonergic and endocannabinoid systems, both of which are intrinsically involved in consciousness and cognitive function.
