PRESCRIPTION DRUG
Tramadol hydrochloride ER tablets are indicated for the management of moderate to moderately severe chronic pain in adults who require around-the-clock treatment of their pain for an extended period of time. Tramadol hydrochloride ER tablets should not be administered to patients who have previously demonstrated hypersensitivity to tramadol, any other component of this product or opioids. Tramadol hydrochloride ER tablets are contraindicated in any situation where opioids are contraindicated, including acute intoxication with any of the following: alcohol, hypnotics, narcotics, centrally acting analgesics, opioids or psychotropic drugs. Tramadol hydrochloride ER tablets may worsen central nervous system and respiratory depression in these patients. Tramadol hydrochloride is a mu-agonist opioid. Tramadol, like other opioids used in analgesia, can be abused and is subject to criminal diversion. Drug addiction is characterized by compulsive use, use for non-medical purposes, and continued use despite

Abbreviated New Drug Application
TRAMADOL HYDROCHLORIDE - TRAMADOL HYDROCHLORIDE TABLET, EXTENDED RELEASE PHYSICIANS TOTAL CARE, INC. ---------- DESCRIPTION Tramadol hydrochloride is a centrally acting synthetic analgesic in an extended-release formulation. The chemical name is (±) cis-2-[(dimethylamino)methyl]-1-(3-methoxyphenyl) cyclohexanol hydrochloride. Its structural formula is: The molecular weight of tramadol hydrochloride is 299.8. It is a white, bitter, crystalline and odorless powder that is readily soluble in water and ethanol and has a pKa of 9.41. The n-octanol/water log partition coefficient (logP) is 1.35 at pH 7. Tramadol hydrochloride Extended-Release (ER) tablets contain 100 mg or 200 mg of tramadol hydrochloride in an extended-release formulation. The tablets are white to off-white in color and contain the inactive ingredients colloidal silicone dioxide, dibutyl sebacate, ethylcellulose, magnesium stearate, polyvinyl alcohol, povidone K-90, and an imprinting agent, Opacode S-1-17823 black, which contains the following ingredients: shellac, iron oxide black, isopropyl alcohol, n-butyl alcohol, propylene glycol, and ammonium hydroxide. CLINICAL PHARMACOLOGY MECHANISM OF ACTION Tramadol hydrochloride is a centrally acting synthetic opioid analgesic. Although its mode of action is not completely understood, from animal tests, at least two complementary mechanisms appear applicable: binding of parent and M1 metabolite to µ-opioid receptors and weak inhibition of reuptake of norepinephrine and serotonin. Opioid activity is due to both low affinity binding of the parent compound and higher affinity binding of the O-demethylated metabolite 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. Tramadol- induced analgesia is only partially antagonized by the opiate antagonist naloxone in several animal tests. The relative contribution of both tramadol and M1 to human analgesia is dependent upon the plasma concentrations of each Aqra d-dokument sħiħ
