Zamadol 24hr

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.

Tramadol mimicks the action of our 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.

Tramadol also works by enhancing the activity of neurotransmitters in the brain and spinal cord. Neurotransmitters are chemical compounds that act as chemical messengers between the nerve cells. Tramadol enhances the effect of the neurotransmitters serotonin and noradrenaline, and this action also helps relieve pain.

Tramadol is a fairly strong painkiller that is used in the management of moderate to severe pain.

Zamadol 24hr tablets are modified release tablets. They are designed to release the tramadol slowly and continuously over 24 hours to help provide steady blood levels of the medicine throughout the day. This provides prolonged pain relief, so these tablets are taken once a day, at the same time each day. They should be swallowed whole to avoid damaging the modified release action.
