Health Centres - Palladone SR
How does it work?
Palladone SR capsules contain the active ingredient hydromorphone hydrochloride, which is a type of medicine called an opioid analgesic (painkiller). It is related to morphine.
Opioid painkillers work by mimicking the action of naturally occurring pain-reducing chemicals called endorphins. Endorphins are found in the brain and spinal cord and reduce pain by combining with opioid receptors.
Hydromorphone mimicks the action of natural endorphins by combining with the opioid receptors in the brain and spinal cord. This blocks the transmission of pain signals sent by the nerves to the brain. Therefore, even though the cause of the pain may remain, less pain is actually felt.
Hydromorphone is used to relieve severe pain caused by cancer.
Palladone SR capsules are sustained-release capsules. They are designed to release the hydromorphone slowly and continuously over a few hours. This provides prolonged pain relief, so these capsules are taken every 12 hours.
What is it used for?

Warning!
- This medicine may cause drowsiness. If affected do not drive or operate machinery. Alcohol should be avoided.
- If this medicine is taken for prolonged periods of time, the body can become tolerant to it and it may become less effective at relieving pain. This means that with time, higher doses may be needed to control pain. With prolonged use the body may also become dependent on the medicine.
