Therapeutic misadventure with paracetamol: fact or fiction?

American journal of therapeutics·2001

Area of Science:

  • Pharmacology
  • Clinical Medicine
  • Drug Safety

Background:

  • Paracetamol (acetaminophen) has been clinically used since 1893 and commercially available since the 1950s.
  • Initially recognized for its safety, concerns arose in 1966 regarding liver damage from overdose, treatable with N-acetylcysteine.
  • The 1980s saw paracetamol become a preferred pediatric analgesic due to aspirin's link to Reye's syndrome.

Purpose of the Study:

  • To review the established efficacy and safety profile of paracetamol (acetaminophen).
  • To highlight its current role as a first-line analgesic and antipyretic across diverse patient populations.
  • To explore potential future therapeutic applications of paracetamol.

Main Methods:

  • Literature review of historical clinical use and safety data.
  • Analysis of paracetamol's role in pediatric analgesia post-Reye's syndrome discovery.
  • Examination of current clinical guidelines and contraindications for its use.

Main Results:

  • Paracetamol is a standard treatment for mild to moderate pain and fever in adults and children.
  • It demonstrates a favorable safety profile when used correctly, with rare serious adverse events.
  • Contraindications include nonsteroidal anti-inflammatory drug (NSAID) sensitivity and gastrointestinal risks, where paracetamol is preferred.

Conclusions:

  • Paracetamol remains a crucial first-line therapy for pain and fever management in various patient groups.
  • Its safety profile is well-established, with effective management for overdose toxicity.
  • Ongoing research into its mechanism may reveal broader therapeutic uses, including potential antioxidant and anti-atherosclerotic effects.
