USES _PHARMACODYNAMICS _ Tramadol is a centrally-acting synthetic analgesic of the aminocyclohexanol group with opioid-like effects. It is not derived from natural sources, nor is it chemically related to opiates. Although pre-clinical testing has not completely explained the mode of action, at least two complementary mechanisms appear applicable: binding to µ-opioid receptors and inhibition of re-uptake of noradrenaline and serotonin. The opioid-like activity of tramadol derives from low affinity binding of the parent compound to µ-opioid receptors and higher affinity binding of the principal active metabolite, _O_-desmethyltramadol, denoted M1, to µ-opioid receptors. In animal models, M1 is up to 6 times more potent than tramadol in producing analgesia and 200 times more potent in µ- opioid binding. The contribution to human analgesia of tramadol relative to M1 is unknown. Both animal and human studies have shown that antinociception induced by tramadol is only partially antagonised by the opiate antagonist naloxone. In addition, tramadol has been shown to inhibit re-uptake of noradrenaline and serotonin _in vitro_, as have some other opioid analgesics. These latter mechanisms may contribute independently to the overall analgesic profile of tramadol. The analgesic effect is dose-dependant, but the relationship between serum concentrations and analgesic effect varies considerably between individuals. In one study, the median serum concen Preberite celoten dokument
