What Type of Medicine is Tracet?

Tracet is a fixed-dose combination (FDC) medicinal product, chemically classified as a synthetic analgesic. It is a prescription-only medicine that belongs to the pharmacological group of centrally acting analgesics, meaning its primary therapeutic effect involves influencing pain signals within the central nervous system. The product's classification is defined by the strategic combination of its two active components, which comprise an opioid agent and a non-opioid agent. This dual nature distinguishes it from common single-agent pain relievers and is essential to its therapeutic identity.

Composition: What Active Ingredients Does Tracet Contain?

The active ingredients are the International Nonproprietary Names (INN): Acetaminophen (Paracetamol) and Tramadol Hydrochloride. The combination of these two agents is utilized as a strategy to enhance pain relief efficacy, as the individual mechanisms of action are complementary and work synergistically. The Acetaminophen component works systemically, while the Tramadol Hydrochloride component acts centrally, targeting opioid receptors and inhibiting the reuptake of specific neurotransmitters. This specific composition provides a multimodal approach to pain relief.

General Purpose of the Combination

The general purpose of Tracet is the effective management of pain, particularly for discomfort categorized as moderate to severe when single-agent treatment is insufficient. The combination of tramadol and acetaminophen is used to reduce pain scores. This makes the combination a preferred option in scenarios where robust relief is needed for adult patients, intervening at multiple points in the body's complex pain signaling process.

What side effects are possible with Tracet?

Possible Side Effects and Safety Information

The safety profile for this fixed-dose combination of Acetaminophen and Tramadol Hydrochloride is formally classified by regulatory authorities (such as the FDA and EMA) according to the frequency and the System-Organ-Class (SOC) affected. Adverse effects are typically grouped by whether they are very common, common, uncommon, or rare.

Adverse reactions impacting the Nervous System Disorders and Gastrointestinal Disorders are the most frequently reported. Reactions officially classified as Very Common (affecting ge1 in 10 patients) include nausea, dizziness, and somnolence (drowsiness). Common effects (affecting ge1 in 100 to <1 in 10 patients) include vomiting, constipation, dry mouth, and headache.

Serious Adverse Reactions and Safety Constraints

Official regulatory documentation includes specific warnings regarding serious risks. The Acetaminophen component carries a risk of severe hepatotoxicity (liver failure), and the medication is formally contraindicated in individuals with severe hepatic impairment. The Tramadol component carries an officially documented risk of developing drug dependence and abuse, particularly with prolonged or chronic use, and a potential for life-threatening respiratory depression. Warnings also address the risk of convulsions (seizures) and the rare but severe risk of Serotonin Syndrome.

Safety notes for specific populations are also documented. Older adults may experience a higher incidence of certain effects. The drug is not advised for use in individuals with severe hepatic impairment, and caution is advised for those with renal impairment due to the potential for component accumulation.

Time-related patterns are noted: the most common effects, such as dizziness and nausea, are often more frequently observed at the start of treatment.

Overdose and Emergency Response

Overdose and when to seek help — Official Regulatory Information

Overdose with this medication carries a high risk of being life-threatening or fatal due to the effects of its two active components. Immediate medical attention is required for any suspected overdose or accidental ingestion.

Overdose Presentations

Symptoms of a severe overdose can manifest as signs of opioid toxicity and hepatotoxicity (liver damage). Opioid-related symptoms include serious, life-threatening respiratory depression (slowed or stopped breathing), profound sedation progressing to stupor or coma, skeletal muscle flaccidity, bradycardia, and hypotension. Massive overdose can lead to circulatory collapse and cardiac arrest.

Overdose with the acetaminophen component is associated with acute liver failure, which may necessitate a liver transplant or result in death.

Required Emergency Action

Accidental ingestion of even a single dose, particularly by children, can be fatal. The risk of overdose is increased with misuse, abuse, or the concomitant use of other Central Nervous System (CNS) depressants like benzodiazepines and alcohol. The required emergency action includes supportive care and may involve the administration of an opioid antagonist like naloxone to counteract respiratory depression.

Therapeutic Uses of Tracet

Tracet is used to help manage the overall symptom burden associated with moderate to severe acute pain, which is discomfort that interferes significantly with routine activities. It is applied in clinical settings that involve acute or unstable symptom patterns, as commonly used across conditions presenting with acute episodes. The medication is appropriate for addressing symptoms related to physical discomfort, which may include painful episodes associated with sprains, strains, certain injuries, or discomfort arising from the muscles and joints, such as that linked to moderate osteoarthritis. The combination is indicated for these clinical applications.


“It is relevant when supportive symptom management is appropriate for episodes where discomfort becomes temporarily overwhelming.”


Quick Fact: Support for Symptomatic Episodes

Tracet offers symptomatic relief that helps patients cope more steadily with difficult episodes. It is applied when symptoms create noticeable physiological strain, and is considered relevant for managing episodes where symptoms may intensify temporarily. The use of this medicine supports general well-being during symptomatic phases and is applied when groups of symptoms appear suddenly or fluctuate.

Eligibility and Restrictions for Use

Tracet (Tramadol/Acetaminophen) eligibility is strictly defined by regulatory documents, confining its use to adults 18 years and older who do not have documented contraindications. Use is generally restricted to patients whose pain requires this specific combination.

Contraindications (Must Not Use)

  • Pediatric Patients: Contraindicated in all children younger than 12 years. It is also prohibited for post-operative pain management in adolescents under 18 following tonsillectomy or adenoidectomy.
  • Organ Impairment: Patients with severe hepatic impairment or severe renal impairment (creatinine clearance <10 ml/min) must not use this medicine.
  • Concomitant Drugs: Prohibited if taking Monoamine Oxidase Inhibitors (MAOIs) or within 14 days of stopping MAOI therapy.
  • Acute States: Contraindicated in cases of acute intoxication by alcohol, hypnotics, opioids, or psychotropic drugs, or in patients with uncontrolled epilepsy.

Restricted and Non-Recommended Use

  • Moderate Impairment: Patients with moderate renal or hepatic impairment require careful dose adjustments or prolonged dosing intervals.
  • Reproductive Status: The medicine is not recommended during pregnancy (especially the first and third trimesters) or for breastfeeding mothers.

What should I know about interactions with other medicines?

Interactions with other medicines and products

Official regulatory documentation identifies several categories of substances and medicines that interact with Tracet (Acetaminophen and Tramadol Hydrochloride), primarily through pharmacokinetic and pharmacodynamic mechanisms.

Contraindicated Combinations and Mandatory Restrictions

Co-administration with Monoamine Oxidase Inhibitors (MAOIs) is strictly prohibited due to the risk of Serotonin Syndrome and opioid crisis. A mandatory 14-day washout period is required after discontinuing an MAOI before Tracet can be administered. Co-administration with Alcohol is also strictly prohibited due to the risk of additive Central Nervous System (CNS) depression, potentially leading to profound sedation and respiratory depression.

Documented Pharmacokinetic Interactions

Substances affecting the cytochrome P450 (CYP) enzymes can alter drug exposure. CYP2D6 inhibitors (e.g., fluoxetine, quinidine) may reduce the formation of the active tramadol metabolite, resulting in reduced analgesic effect. CYP3A4 inhibitors (e.g., ketoconazole) may increase tramadol plasma concentrations, while CYP3A4 inducers (e.g., carbamazepine) may reduce them. The exposure to acetaminophen is also restricted; the co-use of other acetaminophen-containing products is constrained to prevent exceeding the regulatory limit.

Pharmacodynamic and Other Interactions

Co-administration with other CNS Depressants (e.g., benzodiazepines) or Serotonergic Drugs (e.g., SSRIs) can result in dangerous additive effects. The tramadol component may also interact with warfarin, potentially causing an increase in International Normalized Ratio (INR).

Mechanism of Action

Tracet, a fixed-dose combination, exerts its effect through the synergistic actions of its two components, paracetamol and tramadol. The paracetamol component acts centrally, likely by inhibiting the enzyme cyclooxygenase (COX), preferentially the COX-2 isoform in the central nervous system (CNS). This inhibition blocks the synthesis of prostaglandins, which are key mediators of cellular signaling cascades in the spinal cord and perivascular spaces. Downstream, this action modulates the neurochemical environment, altering ascending pain signals.

The tramadol component functions as a centrally acting opioid agonist and a monoamine reuptake inhibitor. Tramadol and its active metabolite, O-desmethyl-tramadol (M1), interact with and act as agonists at the mu-opioid receptors in the CNS. This mu-opioid receptor activation modulates calcium and potassium conductance, leading to hyperpolarization and reduced neuronal excitability in afferent pathways. Concurrently, tramadol weakly inhibits the neuronal reuptake of norepinephrine and serotonin in the synaptic cleft. This increases the concentration of these neurotransmitters, enhancing the descending inhibitory pathways originating from the brainstem. The net systemic physiological consequence is the altered perception of and response to nociceptive input.

Dosage and Administration Information

How to Use Tracet

The administration of the Tracet fixed-dose combination product is characterized by specific parameters concerning its route, dosing schedule, and duration of use. The medicine is supplied as an oral tablet and is to be taken with or without food. The tablet is swallowed whole with liquid.


Dosage and Frequency Guidelines

The standard starting dose for adults is typically two tablets, which corresponds to 75 mg of Tramadol and 650 mg of Acetaminophen. Subsequent doses are typically one or two tablets taken every 4 to 6 hours as required. The time interval between any two doses is not less than six hours to manage the plasma concentration of its components.

The maximum intake does not exceed eight tablets (300 mg Tramadol / 2600 mg Acetaminophen) over a 24-hour period. The therapeutic application is generally limited to a maximum duration of five days.


Population-Specific Use and Restrictions

Adjustments are utilized for specific patient populations. For individuals with moderate renal impairment (creatinine clearance < 30 mL/min), the dosing interval is extended to 12 hours. For older adults (over 75 years of age), a minimum 6-hour dosing interval is recommended. A key restriction is the constraint against concurrent use with any other medicine containing either tramadol or acetaminophen.

Recent Clinical Evidence

Research Evidence / Overview of Studies for Tracet

The following summary describes the types of clinical research that have been conducted to evaluate the Tracet combination, outlining the study designs, the outcomes that were measured, and where evidence remains incomplete or uncertain, based on official regulatory and scientific reviews.


Evidence for Use in Acute Pain

Research for acute pain primarily involves short-term, highly controlled studies. These randomized controlled trials (RCTs) compare the combination against a placebo or its individual components to understand symptom patterns. Studies were mainly conducted during periods of increased symptom activity in otherwise healthy adults and adolescents (aged 12 years and older).

Research explored patterns related to the time reported until initial relief for the combination versus tramadol alone in specific acute models. Evidence currently provides limited insight regarding the combination's evaluation outside of these standardized, short-duration acute pain models. Longer-term outcomes beyond the immediate acute phase remain insufficiently characterized by this body of research.


Evidence for Use in Chronic Pain Conditions

Research exploring the combination in persistent conditions involved intermediate-term RCTs. These studies monitored adults with Chronic Low Back Pain (CLBP) or conditions characterized by functional limitations, like symptomatic Osteoarthritis (OA). The trials typically lasted intermediate durations and were used in observational settings evaluating daily-life functioning.

Studies monitored measurements related to systemic or functional imbalance. Data show patterns related to changes in pain scores measured during the study period; however, findings for functional change and quality of life were observed in some studies but often showed more variability.


Research Gaps and Uncertainties

A key research gap relates to long-term evaluation. The follow-up durations for the key clinical trials are limited, meaning that long-term effects are not fully established. For specific patient populations, such as frail older adults or those with complex comorbidities, data remain insufficient. The results apply only to the populations studied, and the evidence quality varies across studies when examining sustained changes in functional limitations.
