In the third pathway, however, the intermediate product NAPQI is toxic. [67][99] NAC was usually given following a treatment nomogram (one for people with risk factors, and one for those without), but the use of the nomogram is no longer recommended as evidence to support the use of risk factors was poor and inconsistent, and many of the risk factors are imprecise and difficult to determine with sufficient certainty in clinical practice. [120] It has been suggested that contamination of paracetamol with 4-aminophenol, the substance von Mering synthesised it from, may be the cause for his spurious findings. The presence of two activating groups also make the benzene ring highly reactive toward electrophilic aromatic substitution. [149][150][151] In some contexts, such as on prescription bottles of painkillers that incorporate this medicine, it is simply abbreviated as APAP, for acetyl-para-aminophenol. Paracetamol, also known as acetaminophen, is a medication used to treat pain and fever. [22] It is classified as a mild analgesic. [38] Evidence from randomised controlled trials is currently unclear regarding the effectiveness of paracetamol for preventing or treating pain in newborn babies. [113], Despite its common use, the mechanism of action of paracetamol is not completely understood. [74] Kidney damage is seen in rare cases, most commonly in overdose. [98] Kidney failure is also a possible side effect. [53] The Cochrane review of preoperative analgesics for additional pain relief in children and adolescents shows no evidence of benefit in taking paracetamol before dental treatment to help reduce pain after treatment for procedures under local anaesthetic, but the quality of evidence is low.

NAPQI is primarily responsible for the toxic effects of paracetamol; this constitutes an example of toxication. [59][60] NSAIDs, particularly indomethacin and ibuprofen, have also been used, but the evidence for them is also not strong. [54], The efficacy of paracetamol when used in combination with weak opioids (such as codeine) improved for about 50% of people, but with increases in the number experiencing side effects. Indice. [180], The main effect of toxicity in dogs is liver damage, and GI ulceration has been reported. 4,20 € Cantitate. Testo Señorita. [12] Paracetamol is also used for severe pain, such as cancer pain and pain after surgery, in combination with opioid pain medication. Results: 254. [medical citation needed] Treatment is aimed at removing the paracetamol from the body and replenishing glutathione.

[138] In three papers published in the September 1948 issue of the Journal of Pharmacology and Experimental Therapeutics, Bernard Brodie, Julius Axelrod and Frederick Flinn confirmed using more specific methods that paracetamol was the major metabolite of acetanilide in human blood, and established that it was just as efficacious an analgesic as its precursor.

[116], Paracetamol is metabolized primarily in the liver, into toxic and nontoxic products. [120], Paracetamol is the active metabolite of phenacetin and acetanilide, both once popular as analgesics and antipyretics in their own right. [17], Paracetamol is generally safe at recommended doses. [45] Other systematic reviews have also concluded that evidence for its efficacy is lacking. Adăugaţi la lista dorinţelor .
