Tramadol has been used as a painkiller for almost thirty years in both the hospital and the home environment. During this time, research has varied in intensity. As a new drug in the late 1970s, physicians were naturally interested to find out exactly what the medication would do. There was then a lull until the 1990s when it was discovered that Tramadol not only interacts with the opioid receptors, but also acts to inhibit the reuptake of serotonin and noradrenaline. In a hospital, Tramadol is a part of the general panel of drugs and therapies used to relieve pain, particularly following surgery where pain may be acute. There is clear and continuing evidence of good pain relief when administered intravenously or by injection. However, its use as a part of the anesthetic is now reduced because it seems to allow some level of consciousness during the operation. Patients are able to recall some events during surgery. There is also some evidence of breathing difficulties after surgery where large amounts of Tramadol have been used. Although some patients experience nausea and, occasionally, vomiting, there are rarely any adverse effects when Tramadol is used after surgery. This makes it the preferred choice as against the other narcotic painkillers because the risks of addiction are minimal.
