Drug Names(s): Tramadol OAD, Once-daily tramadol, Tridural, Tradorec XL, NS-24, Onetram

Description: Labopharm is developing a once-daily formulation of tramadol (Tramadol OAD). Tramadol is a non-scheduled, centrally acting analgesic for the treatment of pain. The once-daily tramadol product consists of a dual matrix delivery system designed to provide both rapid and sustained drug release to maintain blood levels within the therapeutic range. Although the mode of action of tramadol is not completely understood, several complementary mechanisms appear applicable: mild agonism of parent and M1 metabolite to µ-opioid receptors, weak inhibition of reuptake of norepinephrine and serotonin, and modulation of the GABAergic system.
