Its mode of action resembles that of narcotics, but it has significantly less potential for abuse and addiction than the narcotics. Tramadol is as effective as narcotics in relieving pain but does not depress respiration, a side effect of most narcotics. Tramadol is not a nonsteroidal antiinflammatory drug (NSAID), and does not have the increased risk of stomach ulceration and internal bleeding that can occur with the use of NSAIDs. Storage: Store at room temperature, sealed container. Prescribed For: Tramadol is used in the management of moderate to moderately severe pain. Dosing: May be taken with or without food. Drug Interactions: Tramadol can impair thinking and the physical abilities required for driving or operating machinery. Tramadol should be avoided in patients intoxicated with alcohol, hypnotics, and narcotics. Large doses of tramadol administered with alcohol or anesthetic agents can impair breathing. Tramadol can increase the risk of seizure in epileptic patients, especially with simultaneous use of tricyclic antidepressants, such as Elavil. No dosage adjustment or reduction is necessary in healthy elderly patients 65-75 years of age. Patients over the age of 75 years, and those with liver and kidney dysfunction may need lower dosages. The safety of tramadol in children has not been established. Tramadol may rarely be habit forming. Tramadol should be avoided in patients with a history of opiate addiction or hypersensitivity to opiate medications. Pregnancy: The safety of tramadol during pregnancy has not been established. Nursing Mothers: The safety of tramadol in nursing mothers has not been established. Side Effects: Tramadol is generally well tolerated and side effects are usually transient. Commonly reported side effects include nausea, constipation, dizziness, headache, drowsiness, and vomiting. Less commonly reported side effects include itching, sweating, dry mouth, diarrhea, rash, visual disturbances, and vertigo.

Metabolism Hepatic demethylated & glucuronidated Elimination half-life 5-7 hours Excretion Renal Pregnancy category C (USA) C (Australia) Legal status Schedule 4 (Australia) Routes of administration Oral, IV, IM Tramadol (INN) (IPA: [?tr?m?d?l]) is an atypical opioid which is a centrally acting analgesic, used for treating moderate to severe pain. It is a synthetic agent, unrelated to other opioids, and appears to have actions on the GABAergic, noradrenergic and serotonergic systems. Tramadol was developed by the German pharmaceutical company Grunenthal GmbH and marketed under the trade name Tramal. Grunenthal has also cross licensed the drug to many other pharmaceutical companies that market it under various names, some of which are listed below. Tramadol is available in both injectable (intravenous and/or intramuscular) and oral preparations. It is usually marketed as the hydrochloride salt (tramadol hydrochloride). Dosages vary depending on the degree of pain experienced by the patient. Tramadol is approximately 10% as potent as morphine, when given by the IV/IM route. Oral doses range from 50–400 mg daily, with up to 600 mg daily when given IV/IM. Tramadol has a limited popularity as a recreational drug, and is referred to as "Tram-Tram" amongst users. Mechanism of action The mechanism of action of tramadol has yet to be fully elucidated, but it is believed to work through modulation of the GABAergic, noradrenergic and serotonergic systems. The contribution of non-opioid activity is demonstrated by the analgesic effects of tramadol not being fully antagonised by the ?-opioid receptor antagonist naloxone. Tramadol is marketed as a racemic mixture with a weak affinity for the ?-opioid receptor (approximately 1/6000th that of morphine). The (+)-enantiomer is approximately four times more potent than the (-)-enantiomer in terms of ?-opioid receptor affinity and 5-HT reuptake, whereas the (-)-enantiomer is responsible for noradrenaline reuptake effects (Shipton, 2000). These actions appear to produce a synergistic analgesic effect, with (+)-tramadol exhibiting 10-fold higher analgesic activity than (-)-tramadol (Goeringer et al., 1997). The serotonergic modulating properties of tramadol mean that it has the potential to interact with other serotonergic agents. There is an increased risk of serotonin syndrome when tramadol is taken in combination with serotonin reuptake inhibitors (e.g. SSRIs), since these agents not only potentiate the effect of 5-HT but also inhibit tramadol's metabolism. Metabolism Tramadol undergoes hepatic metabolism via the cytochrome P450 isozyme CYP2D6, being O- and N-demethylated to 5 different metabolites. Of these, M1 is the most significant since it has 200 times the ?-affinity of (+)-tramadol, and furthermore has an elimination half-life of 9 hours compared to 6 hours for tramadol itself. In the 6% of the population who have slow CYP2D6 activity, there is therefore a slightly reduced analgesic effect. Phase II hepatic metabolism renders the metabolites water-soluble and they are renally excreted. Thus reduced doses may be used in renal and hepatic impairment. Adverse effects The most commonly reported adverse drug reactions are nausea, vomiting and sweating. Drowsiness is reported, although it is less of an issue compared to other opioids. Respiratory depression, a common side effect of most opioids, is not clinically significant in normal doses. By itself, it does not increase the seizure threshold, though it may do if used in combination with SSRIs, tricyclic antidepressants, or in patients with epilepsy. Dependence Some controversy exists regarding the dependence liability of tramadol. Grunenthal has promoted it as an opioid with a low risk of dependence compared to traditional opioids, claiming little evidence of such dependence in clinical trials. They offer the theory that since the M1 metabolite is the principal agonist at ?-opioid receptors, the delayed agonist activity reduces dependence liability. The noradrenaline reuptake effects may also play a role in reducing dependence. Despite these claims it is apparent, in community practice, that dependence to this agent does occur. This would be expected since analgesic and dependence effects mediated by the same ?-opioid receptor. However, this dependence liability is considered relatively low by health authorities, such that tramadol is classified as a Schedule 4 Prescription Only Medicine in Australia, rather than as a Schedule 8 Controlled Drug like other opioids (Rossi, 2004). Similarly, tramadol is not currently scheduled by the U.S. DEA, unlike other opioid analgesics. Nevertheless, the Prescribing Information for Ultram warns that tramadol "may induce psychic and physical dependence of the morphine-type." Proprietary preparations Grunenthal, which still owns the patent to tramadol, has cross-licensed the agent to various pharmaceutical companies internationally. Thus tramadol is marketed under many trade names including: Adolonta, Contramal, Crispin, Nobligan, Siverol, Tiparol, Toplagic, Tradol, Tradolan, Tralgit, Tramacet, Tramadin, Tramal, Tramahexal, Tramazac, Ultracet, Ultram, Zamadol and Zydol. Abuse Late reports of abuse have been encountered in the United Kingdom through stolen prescriptions. The drug has been discovered to be sold for around ?4-5.00 a gram. It is either snorted, injected or taken oraly per two 50mg capsules, also poured into 1g capsules and taken as a "shot". Usually followed by an increased dose due to metabolic variation.

Sells Tramadol,famous FDA approved brand name and, generic medications with or without prescription, high quality, low prices, secure ordering, free shipping. DRUG CLASS AND MECHANISM: Tramadol is an effective pain reliever (analgesic). Its mode of action resembles that of narcotics, but it has significantly less potential for abuse and addiction than the narcotics. Tramadol is as effective as narcotics in relieving pain but does not depress respiration, a side effect of most narcotics. Tramadol is not a nonsteroidal antiinflammatory drug (NSAID), and does not have the increased risk of stomach ulceration and internal bleeding that can occur with the use of NSAIDs. DRUG INTERACTIONS: Tramadol can impair thinking and the physical abilities required for driving or operating machinery. Tramadol should be avoided in patients intoxicated with alcohol, hypnotics, and narcotics. Large doses of tramadol administered with alcohol or anesthetic agents can impair breathing. Tramadol can increase the risk of seizure in epileptic patients, especially with simultaneous use of tricyclic antidepressants, such as Elavil. No dosage adjustment or reduction is necessary in healthy elderly patients 65-75 years of age. Patients over the age of 75 years, and those with liver and kidney dysfunction may need lower dosages. The safety of tramadol in children has not been established. Tramadol may rarely be habit forming. Tramadol should be avoided in patients with a history of opiate addiction or hypersensitivity to opiate medications. I was in a really hepeless state when I first was given Tramadol. Other medicaments were ineffective and I was in pain very often. One day I found Tramadol gives the best result in traumatic pain. I ask the doctor for this medicine and since then I take 200 mg dose daily. I must be carefull because it may staggers, so it's better for me to stay in bed for a while. I am really happy taking Tramadol which alleviates my pain a lot! Richard from U.K. I think that Tramadol is the best medicament for everyone who suffers and it always appeases a pain.

Tramadol (INN) (IPA: [E?trA¦mE™dE’l]) is an atypical opioid which is a centrally acting analgesic, used for treating moderate to severe pain. It is a synthetic agent, unrelated to other opioids, and appears to have actions on the GABAergic, noradrenergic and serotonergic systems. Tramadol was developed by the German pharmaceutical company GrA?nenthal GmbH and marketed under the trade name Tramal. GrA?nenthal has also cross licensed the drug to many other pharmaceutical companies that market it under various names, some of which are listed below. Tramadol is available in both injectable (intravenous and/or intramuscular) and oral preparations. It is usually marketed as the hydrochloride salt (tramadol hydrochloride). Dosages vary depending on the degree of pain experienced by the patient. Tramadol is approximately 10% as potent as morphine, when given by the IV/IM route. Oral doses range from 50aˆ“400 mg daily, with up to 600 mg daily when given IV/IM. Tramadol is used to relieve moderate to moderately severe pain. It may be used to treat pain caused by surgery and chronic conditions such as cancer or joint pain. Tramadol is in a class of medications called opiate (narcotic) analgesics. It works by decreasing the body's sense of pain. Commonly reported side effects include nausea, constipation, dizziness, headache, drowsiness, and vomiting. Less commonly reported side effects include itching, sweating, dry mouth, diarrhea, rash, visual disturbances, and vertigo.

Where can I get more information? • Your pharmacist has more information about tramadol written for health professionals that you may read. The molecular weight of tramadol hydrochloride is 299.8. Tramadol hydrochloride is a white, bitter, crystalline and odorless powder. It 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. ULTRAM tablets contain 50 mg of tramadol hydrochloride and are white in color. Inactive ingredients in the tablet are corn starch, hydroxypropyl methylcellulose, lactose, magnesium stearate, microcrystalline cellulose, polyethylene glycol, polysorbate 80, sodium starch glycolate, titanium dioxide and wax. CLINICAL PHARMACOLOGY Pharmacodynamics ULTRAM 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 compound (see CLINICAL PHARMACOLOGY , Pharmacokinetics ). Tramadol has been shown to inhibit reuptake of norepinephrine and serotonin in vitro , as have some other opioid analgesics. These mechanisms may contribute independently to the overall analgesic profile of ULTRAM. Analgesia in humans begins approximately within one hour after administration and reaches a peak in approximately two to three hours. Apart from analgesia, ULTRAM administration may produce a constellation of symptoms (including dizziness, somnolence, nausea, constipation, sweating and pruritus) similar to that of other opioids. In contrast to morphine, tramadol has not been shown to cause histamine release. At therapeutic doses, ULTRAM has no effect on heart rate, left-ventricular function or cardiac index. Orthostatic hypotension has been observed. Pharmacokinetics The analgesic activity of ULTRAM is due to both parent drug and the M1 metabolite (see CLINICAL PHARMACOLOGY , Pharmacodynamics ). Tramadol is administered as a racemate and both the [-] and [+] forms of both tramadol and M1 are detected in the circulation. Tramadol is well absorbed orally with an absolute bioavailability of 75%. Tramadol has a volume of distribution of approximately 2.7L/kg and is only 20% bound to plasma proteins. Tramadol is extensively metabolized by a number of pathways, including CYP2D6 and CYP3A4, as well as by conjugation of parent and metabolites. One metabolite, M1, is pharmacologically active in animal models. The formation of M1 is dependent upon CYP2D6 and as such is subject to inhibition, which may affect the therapeutic response (see PRECAUTIONS , Drug Interactions ). Tramadol and its metabolites are excreted primarily in the urine with observed plasma half-lives of 6.3 and 7.4 hours for tramadol and M1, respectively. Linear pharmacokinetics have been observed following multiple doses of 50 and 100 mg to steady-state. Absorption: Racemic tramadol is rapidly and almost completely absorbed after oral administration. The mean absolute bioavailability of a 100 mg oral dose is approximately 75%. The mean peak plasma concentration of racemic tramadol and M1 occurs at two and three hours, respectively, after administration in healthy adults. In general, both enantiomers of tramadol and M1 follow a parallel time course in the body following single and multiple doses although small differences (~ 10%) exist in the absolute amount of each enantiomer present. Steady-state plasma concentrations of both tramadol and M1 are achieved within two days with q.i.d. dosing. There is no evidence of self-induction (see Figure 1 and Food Effects: Oral administration of ULTRAM with food does not significantly affect its rate or extent of absorption, therefore, ULTRAM can be administered without regard to food. Distribution: The volume of distribution of tramadol was 2.6 and 2.9 liters/kg in male and female subjects, respectively, following a 100 mg intravenous dose. The binding of tramadol to human plasma proteins is approximately 20% and binding also appears to be independent of concentration up to 10 µg/mL. Saturation of plasma protein binding occurs only at concentrations outside the clinically relevant range. Metabolism: Tramadol is extensively metabolized after oral administration. Approximately 30% of the dose is excreted in the urine as unchanged drug, whereas 60% of the dose is excreted as metabolites. The remainder is excreted either as unidentified or as unextractable metabolites. The major metabolic pathways appear to be N - and O - demethylation and glucuronidation or sulfation in the liver. One metabolite ( O -desmethyltramadol, denoted M1) is pharmacologically active in animal models. Formation of M1 is dependent on CYP2D6 and as such is subject to inhibition, which may affect the therapeutic response (see PRECAUTIONS , Drug Interaction ). Approximately 7% of the population has reduced activity of the CYP2D6 isoenzyme of cytochrome P-450. These individuals are "poor metabolizers" of debrisoquine, dextromethorphan, tricyclic antidepressants, among other drugs. Based on a population PK analysis of Phase I studies in healthy subjects, concentrations of tramadol were approximately 20% higher in "poor metabolizers" versus "extensive metabolizers," while M1 concentrations were 40% lower. Concomitant therapy with inhibitors of CYP2D6 such as fluoxetine, paroxetine and quinidine could result in significant drug interactions. In vitro drug interaction studies in human liver microsomes indicate that inhibitors of CYP2D6 such as fluoxetine and its metabolite norfluoxetine, amitriptyline and quinidine inhibit the metabolism of tramadol to various degrees, suggesting that concomitant administration of these compounds could result in increases in tramadol concentrations and decreased concentrations of M1. The full pharmacological impact of these alterations in terms of either efficacy or safety is unknown. Concomitant use of SEROTONIN re-uptake INHIBITORS and MAO INHIBITORS may enhance the risk of adverse events, including seizure (see WARNINGS ) and serotonin syndrome. Elimination: Tramadol is eliminated primarily through metabolism by the liver and the metabolites are eliminated primarily by the kidneys. The mean terminal plasma elimination half-lives of racemic tramadol and racemic M1 are 6.3 ± 1.4 and 7.4 ± 1.4 hours, respectively. The plasma elimination half-life of racemic tramadol increased from approximately six hours to seven hours upon multiple dosing. Special Populations Renal: Impaired renal function results in a decreased rate and extent of excretion of tramadol and its active metabolite, M1. In patients with creatinine clearances of less than 30 mL/min, adjustment of the dosing regimen is recommended (see DOSAGE AND ADMINISTRATION ). The total amount of tramadol and M1 removed during a 4-hour dialysis period is less than 7% of the administered dose. Hepatic: Metabolism of tramadol and M1 is reduced in patients with advanced cirrhosis of the liver, resulting in both a larger area under the concentration time curve for tramadol and longer tramadol and M1 elimination half-lives (13 hrs. for tramadol and 19 hrs. for M1). In cirrhotic patients, adjustment of the dosing regimen is recommended (see DOSAGE AND ADMINISTRATION ). Geriatric: Healthy elderly subjects aged 65 to 75 years have plasma tramadol concentrations and elimination half-lives comparable to those observed in healthy subjects less than 65 years of age. In subjects over 75 years, maximum serum concentrations are elevated (208 vs. 162 ng/mL) and the elimination half-life is prolonged (7 vs. 6 hours) compared to subjects 65 to 75 years of age. Adjustment of the daily dose is recommended for patients older than 75 years (see DOSAGE AND ADMINISTRATION ). Gender: The absolute bioavailability of tramadol was 73% in males and 79% in females. The plasma clearance was 6.4 mL/min/kg in males and 5.7 mL/min/kg in females following a 100 mg IV dose of tramadol. Following a single oral dose, and after adjusting for body weight, females had a 12% higher peak tramadol concentration and a 35% higher area under the concentration-time curve compared to males. The clinical significance of this difference is unknown. Clinical Studies ULTRAM has been given in single oral doses of 50, 75 and 100 mg to patients with pain following surgical procedures and pain following oral surgery (extraction of impacted molars). In single-dose models of pain following oral surgery, pain relief was demonstrated in some patients at doses of 50 mg and 75 mg. A dose of 100 mg ULTRAM tended to provide analgesia superior to codeine sulfate 60 mg, but it was not as effective as the combination of aspirin 650 mg with codeine phosphate 60 mg. ULTRAM has been studied in three long-term controlled trials involving a total of 820 patients, with 530 patients receiving ULTRAM. Patients with a variety of chronic painful conditions were studied in double-blind trials of one to three months duration. Average daily doses of approximately 250 mg of ULTRAM in divided doses were generally comparable to five doses of acetaminophen 300 mg with codeine phosphate 30 mg (TYLENOL® with Codeine #3) daily, five doses of aspirin 325 mg with codeine phosphate 30 mg daily, or two to three doses of acetaminophen 500 mg with oxycodone hydrochloride 5 mg (TYLOX®) daily. Titration Trials In a randomized, blinded clinical study with 129 to 132 patients per group, a 10-day titration to a daily ULTRAM dose of 200 mg (50 mg q.i.d.), attained in 50 mg increments every 3 days, was found to result in fewer discontinuations due to dizziness or vertigo than titration over only 4 days or no titration. In a second study with 54 to 59 patients per group, patients who had nausea or vomiting when titrated over 4 days were randomized to re-initiate ULTRAM therapy using slower titration rates. A 16-day titration schedule, starting with 25 mg qAM and using additional doses in 25 mg increments every third day to 100 mg/day (25 mg q.i.d.), followed by 50 mg increments in the total daily dose every third day to 200 mg/day (50 mg q.i.d.), resulted in fewer discontinuations due to nausea or vomiting and fewer discontinuations due to any cause than did a 10-day titration schedule.

A slight, but statistically significant, increase in two common murine tumors, pulmonary and hepatic, was observed in a mouse carcinogenicity study, particularly in aged mice. Mice were dosed orally up to 30 mg/kg (90 mg/m 2 or 0.36 times the maximum daily human dosage of 246 mg/m 2 ) for approximately two years, although the study was not done with the Maximum Tolerated Dose. This finding is not believed to suggest risk in humans. No such finding occurred in a rat carcinogenicity study (dosing orally up to 30 mg/kg, 180 mg/m 2 , or 0.73 times the maximum daily human dosage). Tramadol was not mutagenic in the following assays: Ames Salmonella microsomal activation test, CHO/HPRT mammalian cell assay, mouse lymphoma assay (in the absence of metabolic activation), dominant lethal mutation tests in mice, chromosome aberration test in Chinese hamsters, and bone marrow micronucleus tests in mice and Chinese hamsters. Weakly mutagenic results occurred in the presence of metabolic activation in the mouse lymphoma assay and micronucleus test in rats. Overall, the weight of evidence from these tests indicates that tramadol does not pose a genotoxic risk to humans. No effects on fertility were observed for tramadol at oral dose levels up to 50 mg/kg (300 mg/m 2 ) in male rats and 75 mg/kg (450 mg/m 2 ) in female rats. These dosages are 1.2 and 1.8 times the maximum daily human dosage of 246 mg/m 2 , respectively. Pregnancy, Teratogenic Effects: Pregnancy Catogery C Tramadol has been shown to be embryotoxic and fetotoxic in mice, (120 mg/kg or 360 mg/m 2 ), rats (>/=25 mg/kg or 150 mg/m 2 ) and rabbits (>/=75 mg/kg or 900 mg/m 2 ) at maternally toxic dosages, but was not teratogenic at these dose levels. These dosages on a mg/m 2 basis are 1.4, >/=0.6, and >/=3.6 times the maximum daily human dosage (246 mg/m 2 ) for mouse, rat and rabbit, respectively. No drug-related teratogenic effects were observed in progeny of mice (up to 140 mg/kg or 420 mg/m 2 ), rats (up to 80 mg/kg or 480 mg/m 2 ) or rabbits (up to 300 mg/kg or 3600 mg/m 2 ) treated with tramadol by various routes. Embryo and fetal toxicity consisted primarily of decreased fetal weights, skeletal ossification and increased supernumerary ribs at maternally toxic dose levels. Transient delays in developmental or behavioral parameters were also seen in pups from rat dams allowed to deliver. Embryo and fetal lethality were reported only in one rabbit study at 300 mg/kg (3600 mg/m 2 ), a dose that would cause extreme maternal toxicity in the rabbit. The dosages listed for mouse, rat and rabbit are 1.7, 1.9 and 14.6 times the maximum daily human dosage (246 mg/m 2 ), respectively The information contained in the Thomson Healthcare (Micromedex) products as delivered by Drugs.com is intended as an educational aid only.

TRAMADOL HYDROCHLORIDE Manufacturer: Ortho-McNeil Prescribing Information DESCRIPTION ULTRAM® (tramadol hydrochloride tablets) is a centrally acting analgesic. The chemical name for tramadol hydrochloride is (±) cis -2-[(dimethylamino)methyl]-1-(3-methoxyphenyl) cyclohexanol hydrochloride. Its structural formula is: The molecular weight of tramadol hydrochloride is 299.8. Tramadol hydrochloride is a white, bitter, crystalline and odorless powder. It 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. ULTRAM tablets contain 50 mg of tramadol hydrochloride and are white in color. Inactive ingredients in the tablet are corn starch, hydroxypropyl methylcellulose, lactose, magnesium stearate, microcrystalline cellulose, polyethylene glycol, polysorbate 80, sodium starch glycolate, titanium dioxide and wax. CLINICAL PHARMACOLOGY Pharmacodynamics ULTRAM 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 compound (see CLINICAL PHARMACOLOGY , Pharmacokinetics ). Tramadol has been shown to inhibit reuptake of norepinephrine and serotonin in vitro , as have some other opioid analgesics. These mechanisms may contribute independently to the overall analgesic profile of ULTRAM. Analgesia in humans begins approximately within one hour after administration and reaches a peak in approximately two to three hours. Apart from analgesia, ULTRAM administration may produce a constellation of symptoms (including dizziness, somnolence, nausea, constipation, sweating and pruritus) similar to that of other opioids. In contrast to morphine, tramadol has not been shown to cause histamine release. At therapeutic doses, ULTRAM has no effect on heart rate, left-ventricular function or cardiac index. Orthostatic hypotension has been observed. Pharmacokinetics The analgesic activity of ULTRAM is due to both parent drug and the M1 metabolite (see CLINICAL PHARMACOLOGY , Pharmacodynamics ). Tramadol is administered as a racemate and both the [-] and [+] forms of both tramadol and M1 are detected in the circulation. Tramadol is well absorbed orally with an absolute bioavailability of 75%. Tramadol has a volume of distribution of approximately 2.7L/kg and is only 20% bound to plasma proteins. Tramadol is extensively metabolized by a number of pathways, including CYP2D6 and CYP3A4, as well as by conjugation of parent and metabolites. One metabolite, M1, is pharmacologically active in animal models. The formation of M1 is dependent upon CYP2D6 and as such is subject to inhibition, which may affect the therapeutic response (see PRECAUTIONS , Drug Interactions ). Tramadol and its metabolites are excreted primarily in the urine with observed plasma half-lives of 6.3 and 7.4 hours for tramadol and M1, respectively. Linear pharmacokinetics have been observed following multiple doses of 50 and 100 mg to steady-state. Absorption: Racemic tramadol is rapidly and almost completely absorbed after oral administration. The mean absolute bioavailability of a 100 mg oral dose is approximately 75%. The mean peak plasma concentration of racemic tramadol and M1 occurs at two and three hours, respectively, after administration in healthy adults. In general, both enantiomers of tramadol and M1 follow a parallel time course in the body following single and multiple doses although small differences (~ 10%) exist in the absolute amount of each enantiomer present. Steady-state plasma concentrations of both tramadol and M1 are achieved within two days with q.i.d. dosing. There is no evidence of self-induction (see Figure 1 and Table 1 below). Figure 1: Mean Tramadol and M1 Plasma Concentration Profiles after a Single 100 mg Oral Dose and after Twenty-Nine 100 mg Oral Doses of Tramadol HCl given TRAMADOL HYDROCHLORIDE Manufacturer: Ortho-McNeil Prescribing Information DESCRIPTION ULTRAM® (tramadol hydrochloride tablets) is a centrally acting analgesic. The chemical name for tramadol hydrochloride is (±) cis -2-[(dimethylamino)methyl]-1-(3-methoxyphenyl) cyclohexanol hydrochloride. Its structural formula is: The molecular weight of tramadol hydrochloride is 299.8. Tramadol hydrochloride is a white, bitter, crystalline and odorless powder. It 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. ULTRAM tablets contain 50 mg of tramadol hydrochloride and are white in color. Inactive ingredients in the tablet are corn starch, hydroxypropyl methylcellulose, lactose, magnesium stearate, microcrystalline cellulose, polyethylene glycol, polysorbate 80, sodium starch glycolate, titanium dioxide and wax. CLINICAL PHARMACOLOGY Pharmacodynamics ULTRAM 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 compound (see CLINICAL PHARMACOLOGY , Pharmacokinetics ). Tramadol has been shown to inhibit reuptake of norepinephrine and serotonin in vitro , as have some other opioid analgesics. These mechanisms may contribute independently to the overall analgesic profile of ULTRAM. Analgesia in humans begins approximately within one hour after administration and reaches a peak in approximately two to three hours. Apart from analgesia, ULTRAM administration may produce a constellation of symptoms (including dizziness, somnolence, nausea, constipation, sweating and pruritus) similar to that of other opioids. In contrast to morphine, tramadol has not been shown to cause histamine release. At therapeutic doses, ULTRAM has no effect on heart rate, left-ventricular function or cardiac index. Orthostatic hypotension has been observed. Pharmacokinetics The analgesic activity of ULTRAM is due to both parent drug and the M1 metabolite (see CLINICAL PHARMACOLOGY , Pharmacodynamics ). Tramadol is administered as a racemate and both the [-] and [+] forms of both tramadol and M1 are detected in the circulation. Tramadol is well absorbed orally with an absolute bioavailability of 75%. Tramadol has a volume of distribution of approximately 2.7L/kg and is only 20% bound to plasma proteins. Tramadol is extensively metabolized by a number of pathways, including CYP2D6 and CYP3A4, as well as by conjugation of parent and metabolites. One metabolite, M1, is pharmacologically active in animal models. The formation of M1 is dependent upon CYP2D6 and as such is subject to inhibition, which may affect the therapeutic response (see PRECAUTIONS , Drug Interactions ). Tramadol and its metabolites are excreted primarily in the urine with observed plasma half-lives of 6.3 and 7.4 hours for tramadol and M1, respectively. Linear pharmacokinetics have been observed following multiple doses of 50 and 100 mg to steady-state. Absorption: Racemic tramadol is rapidly and almost completely absorbed after oral administration. The mean absolute bioavailability of a 100 mg oral dose is approximately 75%. The mean peak plasma concentration of racemic tramadol and M1 occurs at two and three hours, respectively, after administration in healthy adults. In general, both enantiomers of tramadol and M1 follow a parallel time course in the body following single and multiple doses although small differences (~ 10%) exist in the absolute amount of each enantiomer present. Steady-state plasma concentrations of both tramadol and M1 are achieved within two days with q.i.d. dosing. There is no evidence of self-induction (see Figure 1 and Table 1 below). Figure 1: Mean Tramadol and M1 Plasma Concentration Profiles after a Single 100 mg Oral Dose and after Twenty-Nine 100 mg Oral Doses of Tramadol HCl given INDICATIONS AND USAGE ULTRAM is indicated for the management of moderate to moderately severe pain in adults. CONTRAINDICATIONS ULTRAM should not be administered to patients who have previously demonstrated hypersensitivity to tramadol, any other component of this product or opioids. ULTRAM is 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. ULTRAM may worsen central nervous system and respiratory depression in these patients. WARNINGS Seizure Risk Seizures have been reported in patients receiving ULTRAM within the recommended dosage range. Spontaneous post-marketing reports indicate that seizure risk is increased with doses of ULTRAM above the recommended range. Concomitant use of ULTRAM increases the seizure risk in patients taking: Selective serotonin reuptake inhibitors (SSRI antidepressants or anorectics), Tricyclic antidepressants (TCAs), and other tricyclic compounds (e.g., cyclobenzaprine, promethazine, etc.), or Other opioids. Administration of ULTRAM may enhance the seizure risk in patients taking: MAO inhibitors (see also WARNINGS - Use with MAO Inhibitors), Neuroleptics, or Other drugs that reduce the seizure threshold. Risk of convulsions may also increase in patients with epilepsy, those with a history of seizures, or in patients with a recognized risk for seizure (such as head trauma, metabolic disorders, alcohol and drug withdrawal, CNS infections). In ULTRAM overdose, naloxone administration may increase the risk of seizure. Anaphylactoid Reactions Serious and rarely fatal anaphylactoid reactions have been reported in patients receiving therapy with ULTRAM. When these events do occur it is often following the first dose. Other reported allergic reactions include pruritus, hives, bronchospasm, angioedema, toxic epidermal necrolysis and Stevens-Johnson syndrome. Patients with a history of anaphylactoid reactions to codeine and other opioids may be at increased risk and therefore should not receive ULTRAM (see CONTRAINDICATIONS ). Respiratory Depression Administer ULTRAM cautiously in patients at risk for respiratory depression. In these patients alternative non-opioid analgesics should be considered. When large doses of ULTRAM are administered with anesthetic medications or alcohol, respiratory depression may result. Respiratory depression should be treated as an overdose. If naloxone is to be administered, use cautiously because it may precipitate seizures (see WARNINGS , Seizure Risk and OVERDOSAGE ). Interaction With Central Nervous System (CNS) Depressants ULTRAM should be used with caution and in reduced dosages when administered to patients receiving CNS depressants such as alcohol, opioids, anesthetic agents, narcotics, phenothiazines, tranquilizers or sedative hypnotics. ULTRAM increases the risk of CNS and respiratory depression in these patients. Increased Intracranial Pressure or Head Trauma ULTRAM should be used with caution in patients with increased intracranial pressure or head injury. The respiratory depressant effects of opioids include carbon dioxide retention and secondary elevation of cerebrospinal fluid pressure, and may be markedly exaggerated in these patients. Additionally, pupillary changes (miosis) from tramadol may obscure the existence, extent, or course of intracranial pathology. Clinicians should also maintain a high index of suspicion for adverse drug reaction when evaluating altered mental status in these patients if they are receiving ULTRAM. (See Respiratory Depression .) Use in Ambulatory Patients ULTRAM may impair the mental and or physical abilities required for the performance of potentially hazardous tasks such as driving a car or operating machinery. The patient using this drug should be cautioned accordingly. Use With MAO Inhibitors and Serotonin Re-uptake Inhibitors Use ULTRAM with great caution in patients taking monoamine oxidase inhibitors. Animal studies have shown increased deaths with combined administration. Concomitant use of ULTRAM with MAO inhibitors or SSRI's increases the risk of adverse events, including seizure and serotonin syndrome. Withdrawal Withdrawal symptoms may occur if ULTRAM is discontinued abruptly. (See DRUG ABUSE AND DEPENDENCE .) These symptoms may include: anxiety, sweating, insomnia, rigors, pain, nausea, tremors, diarrhea, upper respiratory symptoms, piloerection, and rarely hallucinations. Clinical experience suggests that withdrawal symptoms may be relieved by tapering the medication. Physical Dependence and Abuse ULTRAM may induce psychic and physical dependence of the morphine-type (µ-opioid) (see DRUG ABUSE AND DEPENDENCE ). ULTRAM should not be used in opioid-dependent patients. ULTRAM has been shown to reinitiate physical dependence in some patients that have been previously dependent on other opioids. Dependence and abuse, including drug-seeking behavior and taking illicit actions to obtain the drug, are not limited to those patients with prior history of opioid dependence. Risk of Overdosage Serious potential consequences of overdosage with ULTRAM (tramadol hydrochloride tablets) are central nervous system depression, respiratory depression and death. In treating an overdose, primary attention should be given to maintaining adequate ventilation along with general supportive treatment (see OVERDOSAGE ). PRECAUTIONS Acute Abdominal Conditions The administration of ULTRAM may complicate the clinical assessment of patients with acute abdominal conditions. Use in Renal and Hepatic Disease Impaired renal function results in a decreased rate and extent of excretion of tramadol and its active metabolite, M1. In patients with creatinine clearances of less than 30 mL/min, dosing reduction is recommended (see DOSAGE AND ADMINISTRATION ). Metabolism of tramadol and M1 is reduced in patients with advanced cirrhosis of the liver. In cirrhotic patients, dosing reduction is recommended (see DOSAGE AND ADMINISTRATION ). With the prolonged half-life in these conditions, achievement of steady-state is delayed, so that it may take several days for elevated plasma concentrations to develop. Information for Patients ULTRAM may impair mental or physical abilities required for the performance of potentially hazardous tasks such as driving a car or operating machinery. ULTRAM should not be taken with alcohol containing beverages. ULTRAM should be used with caution when taking medications such as tranquilizers, hypnotics or other opiate containing analgesics. The patient should be instructed to inform the physician if they are pregnant, think they might become pregnant, or are trying to become pregnant (see PRECAUTIONS , Labor and Delivery ). The patient should understand the single-dose and 24-hour dose limit and the time interval between doses, since exceeding these recommendations can result in respiratory depression, seizures and death. Drug Interactions In vitro studies indicate that tramadol is unlikely to inhibit the CYP3A4-mediated metabolism of other drugs when tramadol is administered concomitantly at therapeutic doses. Tramadol does not appear to induce its own metabolism in humans, since observed maximal plasma concentrations after multiple oral doses are higher than expected based on single-dose data. Tramadol is a mild inducer of selected drug metabolism pathways measured in animals. Use With Carbamazepine Patients taking carbamazepine may have a significantly reduced analgesic effect of ULTRAM. Because carbamazepine increases tramadol metabolism and because of the seizure risk associated with tramadol, concomitant administration of ULTRAM and carbamazepine is not recommended. Use With Quinidine Tramadol is metabolized to M1 by CYP2D6. Quinidine is a selective inhibitor of that isoenzyme, so that concomitant administration of quinidine and ULTRAM results in increased concentrations of tramadol and reduced concentrations of M1. The clinical consequences of these findings are unknown. In vitro drug interaction studies in human liver microsomes indicate that tramadol has no effect on quinidine metabolism. Use With Inhibitors of CYP2D6 In vitro drug interaction studies in human liver microsomes indicate that concomitant administration with inhibitors of CYP2D6 such as fluoxetine, paroxetine, and amitriptyline could result in some inhibition of the metabolism of tramadol. Use With Cimetidine Concomitant administration of ULTRAM with cimetidine does not result in clinically significant changes in tramadol pharmacokinetics. Therefore, no alteration of the ULTRAM dosage regimen is recommended. Use With MAO Inhibitors Interactions with MAO Inhibitors , due to interference with detoxification mechanisms, have been reported for some centrally acting drugs (see WARNINGS , Use With MAO Inhibitors ). Use With Digoxin and Warfarin Post-marketing surveillance has revealed rare reports of digoxin toxicity and alteration of warfarin effect, including elevation of prothrombin times. Carcinogenesis, Mutagenesis, Impairment of Fertility A slight, but statistically significant, increase in two common murine tumors, pulmonary and hepatic, was observed in a mouse carcinogenicity study, particularly in aged mice. Mice were dosed orally up to 30 mg/kg (90 mg/m 2 or 0.36 times the maximum daily human dosage of 246 mg/m 2 ) for approximately two years, although the study was not done with the Maximum Tolerated Dose. This finding is not believed to suggest risk in humans. No such finding occurred in a rat carcinogenicity study (dosing orally up to 30 mg/kg, 180 mg/m 2 , or 0.73 times the maximum daily human dosage). Tramadol was not mutagenic in the following assays: Ames Salmonella microsomal activation test, CHO/HPRT mammalian cell assay, mouse lymphoma assay (in the absence of metabolic activation), dominant lethal mutation tests in mice, chromosome aberration test in Chinese hamsters, and bone marrow micronucleus tests in mice and Chinese hamsters. Weakly mutagenic results occurred in the presence of metabolic activation in the mouse lymphoma assay and micronucleus test in rats. Overall, the weight of evidence from these tests indicates that tramadol does not pose a genotoxic risk to humans. No effects on fertility were observed for tramadol at oral dose levels up to 50 mg/kg (300 mg/m 2 ) in male rats and 75 mg/kg (450 mg/m 2 ) in female rats. These dosages are 1.2 and 1.8 times the maximum daily human dosage of 246 mg/m 2 , respectively. Pregnancy, Teratogenic Effects: Pregnancy Catogery C Tramadol has been shown to be embryotoxic and fetotoxic in mice, (120 mg/kg or 360 mg/m 2 ), rats (>/=25 mg/kg or 150 mg/m 2 ) and rabbits (>/=75 mg/kg or 900 mg/m 2 ) at maternally toxic dosages, but was not teratogenic at these dose levels. These dosages on a mg/m 2 basis are 1.4, >/=0.6, and >/=3.6 times the maximum daily human dosage (246 mg/m 2 ) for mouse, rat and rabbit, respectively. No drug-related teratogenic effects were observed in progeny of mice (up to 140 mg/kg or 420 mg/m 2 ), rats (up to 80 mg/kg or 480 mg/m 2 ) or rabbits (up to 300 mg/kg or 3600 mg/m 2 ) treated with tramadol by various routes. Embryo and fetal toxicity consisted primarily of decreased fetal weights, skeletal ossification and increased supernumerary ribs at maternally toxic dose levels. Transient delays in developmental or behavioral parameters were also seen in pups from rat dams allowed to deliver. Embryo and fetal lethality were reported only in one rabbit study at 300 mg/kg (3600 mg/m 2 ), a dose that would cause extreme maternal toxicity in the rabbit. The dosages listed for mouse, rat and rabbit are 1.7, 1.9 and 14.6 times the maximum daily human dosage (246 mg/m 2 ), respectively. Non-teratogenic Effects Tramadol was evaluated in peri- and post-natal studies in rats. Progeny of dams receiving oral (gavage) dose levels of 50 mg/kg (300 mg/m 2 or 1.2 times the maximum daily human tramadol dosage) or greater had decreased weights, and pup survival was decreased early in lactation at 80 mg/kg (480 mg/m 2 or 1.9 and higher the maximum daily human dose). There are no adequate and well-controlled studies in pregnant women. ULTRAM should be used during pregnancy only if the potential benefit justifies the potential risk to the fetus. Neonatal seizures, neonatal withdrawal syndrome, fetal death and still birth have been reported during post-marketing. Labor and Delivery ULTRAM
