Zamadol capsules, Zamadol melt tablets and Zamadol injection all contain the active ingredient tramadol hydrochloride, which is a type of medicine called an opioid painkiller. (NB. Tramadol is also available without a brand name, ie as the generic medicine.)
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. It is given by injection when administration by mouth is not possible, for example for pain following surgery. The injection is given into a muscle or vein, or via a drip into a vein (intravenous infusion).
Zamadol capsules and melt tablets are taken by mouth up to six times a day, depending on the severity of the pain. Zamadol melt tablets are designed to dissolve in the mouth without water and be swallowed with the saliva. Alternatively they can be dissolved in half a glass of water before taking. These forms of tramadol should not be taken more often than every four hours and you should not exceed the dose prescribed by your doctor.
For more prolonged pain relief, modified release forms of tramadol that can be taken once or twice a day are available. See the products linked at the end of this factsheet for more information.
