Paracetamol is a so-called nonacidic antipyretic.
Its mode of action is multifaceted but centres on the central nervous system and spinal cord.
In detail, the following individual effects of paracetamol combine in such a way that the total effect is greater than the sum of its individual components (hyperadditive, synergistic effect).
- Inhibits the enzymes involved in pain development (cyclooxygenases), the pain-generating substances produced by them (prostaglandins) and messengers and mediators (nitrogen monoxide, substance P) in the central nervous system.
- Enhances the body’s pain-inhibiting systems
• Activates serotoninergic pain inhibition pathways
• Interacts with the cannabinoid pain inhibition system
• Affects opioid receptors
Paracetamol reduces fever by centrally acting on the centre responsible for regulating body temperature in the hypothalamus.
