Tradonal ONE

Tradonal ONE Uses, Dosage, Side Effects, Food Interaction and all others data.

Tradonal ONE is a centrally acting synthetic analgesic compound. It inhibits the re uptake of neurotransmitters- serotonin and noradrenaline. Thus it modifies the transmission of pain impulses by activating both descending serotonergic pathways and noradrenergic pathways involved in analgesia. The analgesic effects of Tradonal ONE are mediated via stimulation of mu-opioid receptors and indirect modulation of central monoaminergic inhibitory pathways.

Tradonal ONE modulates the descending pain pathways within the central nervous system through the binding of parent and M1 metabolite to μ-opioid receptors and the weak inhibition of the reuptake of norepinephrine and serotonin.

Apart from analgesia, tramadol may produce a constellation of symptoms (including dizziness, somnolence, nausea, constipation, sweating and pruritus) similar to that of other opioids.

Uses

Tradonal ONE is used for the treatment of moderate to severe painful conditions. These include: Postoperative pain, Colic and spastic pain, Cancer pain, Joint pain, Neck and back pain & Pain associated with osteoporosis.

Tradonal ONE is also used to associated treatment for these conditions: Pain, Acute, Premature Ejaculation, Severe Pain, Acute, moderate, severe Pain, Moderate Pain

How Tradonal ONE works

Tradonal ONE is a centrally acting μ-opioid receptor agonist and SNRI (serotonin/norepinephrine reuptake-inhibitor) that is structurally related to codeine and morphine. Tradonal ONE binds weakly to κ- and δ-opioid receptors and to the μ-opioid receptor with 6000-fold less affinity than morphine.

Tradonal ONE exists as a racemic mixture consisting of two pharmacologically active enantiomers that both contribute to its analgesic property through different mechanisms: (+)-tramadol and its primary metabolite (+)-O-desmethyl-tramadol (M1) are agonists of the μ opioid receptor while (+)-tramadol inhibits serotonin reuptake and (-)-tramadol inhibits norepinephrine reuptake. These pathways are complementary and synergistic, improving tramadol's ability to modulate the perception of and response to pain.

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.

Tradonal ONE has also been shown to affect a number of pain modulators including alpha2-adrenoreceptors, neurokinin 1 receptors, the voltage-gated sodium channel type II alpha subunit, transient receptor potential cation channel subfamily V member 1 (TRPV1 - also known as the capsaicin receptor), muscarinic receptors (M1 and M3), N-methyl-D-aspartate receptor (also known as the NMDA receptor or glutamate receptor), Adenosine A1 receptors, and nicotinic acetylcholine receptor.

In addition to the above neuronal targets, tramadol has a number of effects on inflammatory and immune mediators involved in the pain response. This includes inhibitory effects on cytokines, prostaglandin E2 (PGE2), nuclear factor-κB, and glial cells as well as a change in the polarization state of M1 macrophages.

Dosage

Tradonal ONE dosage

Capsule or Tablet: Usual doses are 50 to 100 mg every four to six hours. For acute pain an initial dose of 100 mg is required. For chronic painful conditions an initial dose of 50 mg is recommended. Subsequent doses should be 50 to 100 mg administered 4-6 hourly. The dose level and frequency of dosing will depend on the severity of the pain.The total daily dosage by mouth should not exceed 400 mg.

Sustained Release Capsuleor Tablet: One SR capsuleor tablet every 12 hours, for example first one in the morning and then at the same time in the evening. The number of capsules taken at a time will depend upon severity of pain, but it should not be taken more frequently than every 12 hours.The total daily dosage by mouth should not exceed 400 mg.

Injection: A dose of 50-100 mg may be given every 4 to 6 hours by intramuscular or by intravenous infusion. For the treatment of postoperative pain,the initial dose is 100 mg followed by 50 mg every 10 to 20 minutes if necessary to a maximum of 250 mg in the first hour. Thereafter, doses are 50 to 100 mg every 4 to 6 hours up to a total daily dose of 600 mg.

Suppository: Tradonal ONE suppository should be administered rectally. For adults usual dose is 100 mg Tradonal ONE Hydrochloride 6 hourly. In general, 400 mg Tradonal ONE Hydrochloride (4 Tradonal ONE suppository) per day sufficient. However, for the treatment of Cancer pain and severe pain after operations much higher daily doses can be used.

Side Effects

Commonly occurring side-effects are dizziness/vertigo, nausea, constipation, headache, somnolence, vomiting, pruritus, CNS stimulation, asthenia, sweating, dyspepsia, dry mouth, diarrhoea.

Less commonly occurring side-effects include malaise, allergic reaction, weight loss, vasodilatation, palpitations, abdominal pain, anorexia, flatulence, GI bleeding, hepatitis, stomatitis etc.

Toxicity

The reported LD50 for tramadol, when administered orally in mice, is 350 mg/kg.

In carcinogenic studies, there are reports of murine tumors which cannot be concluded to be carcinogenic in humans. On the other hand, tramadol showed no evidence to be mutagenic in different assays and does not have effects on fertility. However, there are clear reports of embryotoxicity and fetotoxicity.

Precaution

Respiratory depression: When large doses of tramadol are administered with anaesthetic with anaesthetic medications or alcohol, respiratory depression may result. Therefore, tramadol should be administered cautiously in patients at risk for respiratory depression.

Opioid dependence: Tradonal ONE is not recommended for patients who are dependent on opioids.

Concomitant CNS depressants: Tradonal ONE should be used with caution and in reduced dosages when administering to patients receiving CNS depressants such as alcohol, opioids, anesthetic agents, phenothiazines, tranquilizers or sedative hypnotics.

Concomitant MAO inhibitors: Tradonal ONE should be used with great caution in patients taking MAO inhibitors, since tramadol inhibits the uptake of norepinephrine and serotonin.

Tradonal ONE should be used with caution in patients with increased intracranial pressure or head injury and patients with acute abdominal conditions.

Interaction

In general, physician need not be concerned about drugs interacting with Tradonal ONE. The monoamine oxidase (MAO) inhibitors represent the only drug class not recommended for combination with Tradonal ONE. Concomitant administration of carbamazepine with Tradonal ONE causes a significant increase in Tradonal ONE metabolism and it requires to increase the dose of Tradonal ONE.

Food Interaction

  • Avoid alcohol. Co-administration of alcohol may potentiate the CNS effects of tramadol.
  • Take with or without food. Co-administration of food does not affect pharmacokinetics.

[Moderate] GENERALLY AVOID: Alcohol may potentiate some of the pharmacologic effects of CNS-active agents.

Use in combination may result in additive central nervous system depression and
MANAGEMENT: Patients receiving CNS-active agents should be warned of this interaction and advised to avoid or limit consumption of alcohol.

Ambulatory patients should be counseled to avoid hazardous activities requiring complete mental alertness and motor coordination until they know how these agents affect them, and to notify their physician if they experience excessive or prolonged CNS effects that interfere with their normal activities.

Volume of Distribution

The volume of distribution of tramadol is reported to be in the range of 2.6-2.9 L/kg. Tradonal ONE has high tissue affinity; the total volume of distribution after oral administration was 306L and 203L after parenteral administration. Tradonal ONE crosses the blood-brain barrier with peak brain concentrations occurring 10 minutes following oral administration. It also crosses the placental barrier with umbilical concentrations being found to be ~80% of maternal concentrations.

Elimination Route

Oral Administration

Tradonal ONE is administered as a racemate, with both the [-] and [+] forms of both tramadol and the M1 metabolite detected in circulation. Following administration, racemic tramadol is rapidly and almost completely absorbed, with a bioavailability of 75%. This difference in absorption and bioavailability can be attributed to the 20-30% first-pass metabolism. Peak plasma concentrations of tramadol and the primary metabolite M1 occur at two and three hours, respectively. Following a single oral dose of 100mg of tramadol, the Cmax was found to be approximately 300μg/L with a Tmax of 1.6-1.9 hours, while metabolite M1 was found to have a Cmax of 55μg/L with a Tmax of 3 hours.

Steady-state plasma concentrations of both tramadol and M1 are achieved within two days of dosing. There is no evidence of self-induction. Following multiple oral doses, Cmax is 16% higher and AUC is 36% higher than after a single dose, demonstrating a potential role of saturable first-pass hepatic metabolism in increasing bioavailability.

Intramuscular Administration

Tradonal ONE is rapidly and almost completely absorbed following intramuscular administration. Following injection of 50mg of tramadol, Cmax of 166μg/L was found with a Tmax of 0.75 hours.

Rectal Administration

Following rectal administration with suppositories containing 100mg of tramadol, Cmax of 294μg/L was found with a Tmax of 3.3 hours. The absolute bioavailability was found to be higher than oral administration (77% vs 75%), likely due to reduced first-pass metabolism with rectal administration compared to oral administration.

Half Life

Tradonal ONE reported a half-life of 5-6 hours while the M1 metabolite presents a half-life of 8 hours.

Clearance

In clinical trials, the clearance rate of tramadol ranged from 3.73 ml/min/kg in renal impairment patients to 8.50 ml/min/kg in healthy adults.

Elimination Route

Tradonal ONE is eliminated primarily through metabolism by the liver and the metabolites are excreted primarily by the kidneys, accounting for 90% of the excretion while the remaining 10% is excreted through feces. Approximately 30% of the dose is excreted in the urine as unchanged drug, whereas 60% of the dose is excreted as metabolites.

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.

Pregnancy & Breastfeeding use

Safe use of Tradonal ONE in pregnancy has not been established. Tradonal ONE has been shown to cross the placenta. There are no adequate and well-controlled studies in pregnant women. Therefore, Tradonal ONE should be used during pregnancy only if the potential benefit justifies the risk to the foetus. Tradonal ONE Hydrochloride should not be administered during breast feeding as Tradonal ONE and its metabolites have been detected in breast milk.

Contraindication

Tradonal ONE is contraindicated in persons having hypersensitivity to this drug. It is also contraindicated in acute intoxication with alcohol, hypnotics, centrally acting analgesics, opioids or psychotropic drugs.
