Pharmacology of pain

Created: 29/6/2004
Analgesics may act at different sites:

 They may act at the site of injury and decrease the pain associated with an inflammatory reaction (e.g. non-steroidal anti-inflammatory drugs)

 They may alter nerve conduction (e.g. local anaesthetics)

 They may modify transmission in the dorsal horn (e.g. opioids and some antidepressants)

 They may affect the central component and the emotional aspects of pain (e.g. opioids and antidepressants)
