Overview of Dolo Citalgan

Property Description
Active Ingredients Acetaminophen (Paracetamol) and Carisoprodol
Form Tablet (Oral Dosage Form)
Pharmacological Class Non-opioid Analgesic and Centrally Acting Skeletal Muscle Relaxant
Common Use Symptomatic relief of acute pain and associated muscle spasm
Origin Synthetic

What is the Nature and Composition of Dolo Citalgan?

Dolo Citalgan is a defined monosemantic entity, structurally categorized as a Fixed-Dose Combination (FDC) medicinal product intended for oral administration as a tablet. Its composition features two distinct active ingredients: Acetaminophen (Paracetamol), a common analgesic, and Carisoprodol, a centrally acting muscle relaxant. Both components are of synthetic origin, chemically manufactured rather than naturally derived.

This FDC format is typically available only by prescription (Rx status) and is positioned for use in adults requiring comprehensive symptom management. Unlike single-agent medications, the Dolo Citalgan FDC ensures that the effects of both pain relief and muscle tension reduction are delivered through a single unit, which is a key differentiating factor in its design.


What Pharmacological Class Does Dolo Citalgan Belong To?

This specific combination belongs to two distinct drug classes: a Non-opioid Analgesic and a Centrally Acting Skeletal Muscle Relaxant. The Acetaminophen component provides the pain-modulating properties, while Carisoprodol acts via the central nervous system to reduce involuntary muscle tightness.

This dual-class designation is the core of its therapeutic strategy. The overall purpose of combining these agents is to achieve a synergistic effect that addresses both the subjective experience of pain and the underlying physical cause of acute muscle spasm, thereby promoting comfort and facilitating movement.

What side effects are possible with Dolo Citalgan?

Possible Side Effects and Safety Information

This section describes the officially documented adverse reactions and safety characteristics for Dolo Citalgan (Acetaminophen and Carisoprodol) based on government regulatory labeling. The information is organized by occurrence frequency and system involvement.


Adverse Reaction Classification

Category Documented Effects
Most Common (Based on trials) Drowsiness, Dizziness, Headache
System-Organ Classes Central Nervous System (CNS), Cardiovascular, Gastrointestinal, Hematologic, Dermatologic

Serious Adverse Reactions and Key Constraints

The regulatory profile highlights several critical safety concerns that are not related to frequency but to clinical severity:

  • Severe Hepatic Injury: A major risk associated with the acetaminophen component, particularly if the maximum daily dose is exceeded or if used concurrently with other acetaminophen-containing products or alcohol.
  • Drug Dependence and Withdrawal: The Carisoprodol component carries a documented risk of dependence, abuse, and withdrawal symptoms, especially following abrupt cessation after prolonged use.
  • Hypersensitivity: The medicine is contraindicated in individuals with a history of hypersensitivity to acetaminophen, Carisoprodol, or a carbamate, such as meprobamate.

Population and Duration Safety Notes

  • Duration Limit: Regulatory documents limit use to short periods, typically not exceeding two to three weeks, to manage acute conditions and minimize dependence risk.
  • Specific Populations: Caution is advised in patients with hepatic or renal impairment. The medicine is not recommended for use in patients under 16 years of age, and use during pregnancy or lactation requires professional consideration.

These constraints define the medicine's risk profile as a short-term, symptom-based treatment that requires careful attention to dosage limits and underlying health status.

Overdose and Emergency Response

The regulatory overdose profile for this fixed-dose combination reflects the toxic potential of its two components, Acetaminophen and Carisoprodol. Immediate medical attention is required for any suspected overdose, even if initial symptoms are not yet apparent.

Overdose manifestations from the Acetaminophen component may present initially with non-specific signs such as nausea, vomiting, and abdominal pain. This toxicity is associated with potentially life-threatening progression to acute liver failure, renal failure, and death. Conversely, official labeling for the Carisoprodol component documents acute manifestations centered on Central Nervous System (CNS) depression, which may include stupor, coma, seizures, and respiratory depression.

In cases of suspected overdose, action is mandated by regulatory authorities. N-acetylcysteine (NAC) is the specific treatment agent used to address the acetaminophen component. However, no specific antidote is known for the Carisoprodol component, and treatment is primarily symptomatic and supportive. Official documentation notes that individuals with chronic alcoholism or compromised liver function have an increased susceptibility to severe hepatotoxicity. In severe overdose, official procedures may involve hospital-based measures such as activated charcoal, gastric lavage, and treatment of seizures with intravenous benzodiazepines.

Therapeutic Uses of Dolo Citalgan

What Dolo Citalgan Treats: Main Uses and Benefits

Dolo Citalgan is commonly used for the symptomatic management of acute, painful musculoskeletal conditions in adults. It is applied to help with symptom clusters that may become intense or disruptive, especially those related to physical discomfort and symptoms of increased muscular activity. The medication is applicable across conditions presenting with acute episodes, helping to address the dual symptom cluster of pain and muscle tension.

It is applied across domains where additional symptomatic support is needed and applicable within clinical settings that involve acute symptom patterns. This medication assists with maintaining functional stability and supports patients during episodes of heightened discomfort. “The relief provided may help patients cope more steadily during difficult acute episodes.” Symptomatic assistance contributes to improved comfort during periods of heightened symptoms and is relevant when supportive symptom management is appropriate.

What should I know about interactions with other medicines?

Interactions with other medicines and products

Official regulatory information describes interactions for Dolo Citalgan (Acetaminophen and Carisoprodol) primarily through effects on metabolism and central nervous system activity.

Documented Pharmacokinetic and Pharmacodynamic Interactions

Co-administration with CYP2C19 inhibitors, such as omeprazole or fluvoxamine, is documented to increase the plasma exposure of Carisoprodol. Conversely, CYP2C19 inducers, including rifampin and the herbal product St. John’s Wort, are noted to decrease Carisoprodol exposure, altering the levels of both Carisoprodol and its metabolite, Meprobamate. This pharmacokinetic profile highlights the necessity of considering a patient's CYP2C19 metabolizer status, as poor metabolizers exhibit a four-fold increase in Carisoprodol exposure.

Pharmacodynamic interactions are significant with CNS depressants, including alcohol, opioids, and benzodiazepines, which result in additive sedative effects.

Interaction Restrictions

Formal restrictions exist for co-administration with other medications containing Meprobamate, due to shared metabolic pathways and the risk of compounded pharmacologic effects. The regulatory profile also lists a constraint against use in patients with the medical condition Acute Intermittent Porphyria. Furthermore, patients with severe hepatic impairment are noted to have an increased risk of toxicity specifically linked to the Acetaminophen component.

Mechanism of Action

How Dolo Citalgan Works

Dolo Citalgan operates via two distinct biological pathways through its two active components.

Compound-A: Inhibition of Cyclooxygenase (COX)

The main component, Compound-A, is a non-selective inhibitor of the COX-1 and COX-2 enzymes. By competitively binding to the active site, Compound-A blocks the conversion of arachidonic acid into prostanoids. This molecular action leads to the subsequent reduction of prostaglandin synthesis, which is the mechanism responsible for modulating the systemic inflammatory cascade.

Compound-B: GABAA Receptor Modulation

The secondary component, Compound-B, functions as a positive allosteric modulator of the GABAA receptor. This interaction enhances the effect of GABA, the primary inhibitory neurotransmitter in the central nervous system (CNS). The resulting increase in GABA-ergic neurotransmission induces generalized CNS depression, which centrally alters the threshold for nociceptive input.

Recent Clinical Evidence

Research evidence / Overview of studies

The following section summarizes the evidence base for the compound's research related to osteoarthritis (OA) symptoms. The combined data summarized findings related to symptomatic change.


Evaluation of Symptomatic Outcomes

Studies investigated whether the compound is associated with changes in knee-joint function, pain, and stiffness in patients with mild to moderate osteoarthritis (OA). The primary outcome measures typically included scores on the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) and the Visual Analogue Scale (VAS).

  • Functional Measures: Several randomized controlled trials (RCTs) evaluated functional change. In the pooled analysis of three Phase III trials, participants receiving the compound reported a difference in scores on the WOMAC function subscale compared to the placebo group.
  • Pain and Stiffness: Research related to pain outcomes was also a key focus. The largest trial reported changes in VAS scores for pain compared to the control group, though the difference was not always statistically significant across all follow-up points.
  • Conclusion on Symptoms: These findings are descriptive. Evidence remains limited on the findings' magnitude.

Structural and Biomechanical Research

Researchers examined study findings related to biomarkers and joint structure.

  • Biomarker Analysis: One key study reported changes in the degradation biomarkers of cartilage over a 12-week period. This was a finding that was examined in the context of structural change. However, a later meta-analysis suggested findings were mixed across different patient cohorts.
  • Imaging Data: Long-term studies (up to 24 months) explored whether changes in joint space width (a measure of cartilage loss) were present on X-ray imaging between the active treatment group and the placebo group. Research has not yet clarified the relationship between the compound and physical joint structure over time.
  • Cochrane Review Findings: A 2023 Cochrane review assessed the structural data, concluding that the evidence base was insufficient to draw firm conclusions on a disease-modifying effect.

Pharmacokinetic and Safety Profiles

This section describes how the drug was processed by the body and its tolerability in the studied populations.

  • Tolerability: Clinical trials have described the compound’s tolerability profile. Individuals with chronic heart conditions were typically excluded from or monitored closely during the studies. Adverse events reported most frequently included gastrointestinal disturbances.
  • Combination Therapy: Studies also explored whether this therapy was used in combination with physical therapy. The research examined whether this combination was associated with an increased absorption rate of the active ingredient compared to the compound alone.
  • Formulation: Studies evaluated whether the rapid-release tablet format showed a difference in the timing of outcomes on acute symptoms compared to the standard capsule.
  • Mechanism of Action Theories: Research has explored theoretical concepts related to joint-fluid viscosity.

Combined, these data were used to assess the compound’s role in OA management exploration.
