Tramadol, a centrally acting analgesic structurally related to codeine and morphine, consists of two enantiomers, both of which contribute to analgesic activity via different mechanisms. (+)-Tramadol and the metabolite (+)-O-desmethyl-tramadol (M1) are agonists of the mu opioid receptor. (+)-Tramadol inhibits serotonin reuptake and (-)-tramadol inhibits norepinephrine reuptake, enhancing inhibitory effects on pain transmission in the spinal cord.

Tramadol is structurally related to codeine and morphine, belonging to the opiate agonist class. Tramadol exerts its analgesic activity via at.

Tramadol is administered as a racemic mixture of (+) and (-) tramadol (also known as R, R and S, S tramadol, respectively). Both of which contribute to the analgesic activity, yet via different mechanisms. After oral administration, tramadol is rapidly and almost compley absorbed. Tramadol is extensively metabolized in the liver by O - and N-demethylation and by conjugation reactions to form glucuronides and sulfates. Elimination of Tramadol and its metabolites is predominantly via the kidneys. The O-demethylation of tramadol to its main analgesic effective metabolite, O-desmethyltramadol (M1), is catalyzed by cytochrome P450 (CYP) 2D6.
