Health Centres - Diamorphine
How does it work?
Diamorphine hydrochloride belongs to a group of medicines called opioids. Opioids mimic the effects of naturally occurring pain reducing chemicals (endorphins). They combine with the opioid receptors in the brain and block the transmission of pain signals. Therefore, even though the cause of the pain may remain, less pain is actually felt.
