Form Oral Tablet (e.g., film-coated)
Pharmacological class Non-Steroidal Anti-Inflammatory Drug (NSAID)
Common use Relieves pain and inflammation
Origin Synthetic (chemically-derived)

What is the Core Identity of Bristaflam?

Bristaflam is a prescription brand name medication that contains the single active ingredient, Aceclofenac. It belongs to the major pharmaceutical class known as Non-Steroidal Anti-Inflammatory Drugs (NSAIDs).

Aceclofenac is a synthetic compound classified as an acetic acid derivative, placing it in the same chemical family as diclofenac, though it possesses a modified structure. This structure contributes to its therapeutic precision within the NSAID group. Bristaflam is positioned as a reliable, single-component agent for managing painful, inflammatory conditions.

What is the General Purpose of Aceclofenac?

The primary purpose of Aceclofenac is to provide powerful relief from pain, inflammation, and accompanying fever. This therapeutic action is standard for medicines in the NSAID class.

Aceclofenac is distinguished by its strong anti-inflammatory power, making it a frequent choice for managing flare-ups associated with chronic discomfort. Aceclofenac is a standard analgesic and anti-inflammatory agent. The drug works by addressing the underlying biological processes that cause swelling and pain.

What Form Does Bristaflam Take?

Bristaflam is formulated for oral administration, meaning it is taken by mouth, most commonly as a film-coated tablet. This prescription-only form is designed for systemic absorption.

The tablet ensures the active ingredient, Aceclofenac, is distributed efficiently via the bloodstream to reach deeper sites of inflammation throughout the body. The tablet contains standard pharmaceutical excipients (non-active ingredients) that ensure its stability and reliable release once taken.

What side effects are possible with Bristaflam?

Possible Side Effects and Safety Information

Bristaflam (Aceclofenac) is a Non-Steroidal Anti-Inflammatory Drug (NSAID) and is generally well-tolerated when taken as prescribed. However, like all medicines, it can cause side effects. You should always use the lowest effective dose for the shortest possible duration to minimize risks.

Common Side Effects

The most frequently reported side effects are primarily gastrointestinal and usually mild. These often subside as your body adjusts to the medication:

  • Gastrointestinal: Nausea, vomiting, diarrhea, indigestion (dyspepsia), abdominal pain, and heartburn.
  • Other: Dizziness, headache, and elevated liver enzymes in blood tests.

Serious Side Effects and Warnings

Seek immediate medical attention if you experience signs of a serious reaction or complication, such as:

  • Severe Allergic Reaction: Swelling of the face, lips, tongue, or throat, difficulty breathing, or severe skin rashes (e.g., Stevens-Johnson syndrome).
  • Gastrointestinal Bleeding: Black, tarry stools, or vomiting blood or material that looks like coffee grounds. Aceclofenac increases the risk of ulcers, bleeding, or perforation in the stomach or intestine, especially with long-term or high-dose use.
  • Cardiovascular Risk: NSAIDs may be associated with a small increased risk of serious cardiovascular events like heart attack or stroke, particularly in patients with pre-existing heart conditions or prolonged use.
  • Hepatic or Renal Issues: Yellowing of the skin or eyes (jaundice), or significant changes in urine output, which can indicate liver or severe kidney problems.

Contraindications and Precautions

Do not take Bristaflam if you are allergic to aceclofenac, aspirin, or any other NSAID. Caution is advised, and your doctor should be informed if you have a history of:

  • Stomach ulcers or intestinal bleeding
  • Severe heart, liver, or kidney failure
  • Severe blood clotting or bleeding disorders
  • Asthma or other breathing issues that worsen with NSAIDs

Pregnancy and Breastfeeding: It is not generally recommended for use during pregnancy, especially in the last trimester, and is not recommended while breastfeeding. Always consult your doctor before use. You should also avoid alcohol consumption, as it may increase the risk of stomach bleeding and drowsiness.

Overdose and Emergency Response

Overdose and When to Seek Help

Bristaflam is associated with the active ingredient Metamizole (also known as Dipyrone). Overdose is generally considered uncommon, and in many documented instances, acute ingestion has resulted in mild effects. However, taking a much larger dose than recommended carries a risk of potentially serious and even fatal outcomes.

Reported symptoms of an acute overdose are primarily linked to effects on the central nervous system (CNS) and the gastrointestinal (GI) tract. Early, less severe signs may include stomach pain, nausea, and vomiting. Ingestion of particularly large amounts may lead to more profound CNS effects such as somnolence, confusion, or agitation. Serious toxicity is rare but can manifest as convulsions (seizures), acute renal failure, and a significant drop in blood pressure (shock).

Emergency Actions Required

Immediate medical attention is necessary if an overdose is suspected or confirmed. Call your local emergency number or poison control center right away if you or someone else has taken too much Bristaflam. Do not wait for severe symptoms to develop.

Medical care for an overdose is typically supportive. Treatment may involve measures to limit drug absorption, such as administering activated charcoal if ingestion was recent, and providing intensive monitoring and supportive care for vital signs (e.g., maintaining blood pressure and controlling seizures).

Therapeutic Uses of Bristaflam

What Bristaflam Treats: Main Uses and Benefits

Bristaflam (Aceclofenac) is a Non-Steroidal Anti-Inflammatory Drug (NSAID) used in situations involving certain distressing symptoms related to inflammatory or irritative states of musculoskeletal and joint conditions. Its primary therapeutic role is focused on providing symptomatic relief for adults.

The medication is commonly used across conditions presenting with systemic or localized discomfort, including Rheumatoid Arthritis, Ankylosing Spondylitis, and Osteoarthritis. It is also applied in acute scenarios to assist with the management of pain and swelling following soft tissue injuries or post-dental procedures.

The drug helps address symptom clusters that may become intense or disruptive, such as persistent pain, joint swelling, and significant stiffness. This action contributes to improved day-to-day comfort and supports patients during episodes of heightened discomfort.

“Bristaflam is relevant when supportive symptom management is appropriate for easing challenging symptoms that create noticeable functional strain.”


Quick Fact: Focus on Easing Functional Strain
Bristaflam is relevant for easing challenging symptoms, such as pronounced joint stiffness and restricted movement, to support the maintenance of functional stability during symptomatic phases.

Eligibility and Restrictions for Use

Bristaflam (Aceclofenac) is officially indicated for use only in the adult population. Regulatory documents establish strict, non-negotiable rules for eligibility, defining populations who are prohibited from use (contraindicated) and those who require careful monitoring.

Contraindicated Populations (Must Not Use)

Use of Bristaflam is strictly prohibited if a patient has:

  • Hypersensitivity to Aceclofenac or any other Non-Steroidal Anti-Inflammatory Drug (NSAID) (including those who have experienced asthma, rhinitis, or angioedema after taking aspirin or other NSAIDs).
  • Active or recurrent peptic ulcer/haemorrhage (two or more distinct episodes).
  • Severe Hepatic (liver) or Severe Renal (kidney) Failure.
  • Established Cardiovascular Disease, including Ischaemic Heart Disease, Peripheral Arterial Disease, Cerebrovascular Disease, or Congestive Heart Failure (NYHA Class II–IV).
  • Active bleedings or known bleeding disorders.

Age and Physiological Restrictions

Population Group Eligibility Status (Regulatory Label)
Pediatric (Under 18) Not Recommended (Safety and efficacy data not established)
Third Trimester of Pregnancy Contraindicated
Breastfeeding Not Recommended (Lack of data on secretion into milk)
Mild-to-Moderate Impairment Requires Caution and surveillance (e.g., mild renal impairment, mild hepatic impairment)

Eligibility also requires careful consideration for elderly patients and individuals with established cardiovascular risk factors (e.g., uncontrolled hypertension, diabetes).

What should I know about interactions with other medicines?

Interactions with other medicines and products

Official regulatory information outlines specific documented interaction patterns for Bristaflam (Aceclofenac).

Interaction-Related Restrictions

Classification Interacting Agents Official Statement of Outcome
Contraindicated Other systemic NSAIDs and Aspirin at analgesic doses Increased risk of severe gastrointestinal adverse effects.
Requires Caution Anticoagulants (e.g., Warfarin), Antiplatelet agents, SSRIs, Corticosteroids Increased pharmacodynamic risk of bleeding and ulceration.

Documented Exposure and Effect Modifications

Co-administration with certain medicines may alter their concentration in the body or diminish their therapeutic effects:

  • Exposure Increased: Bristaflam decreases the elimination of substances like Lithium and Methotrexate, resulting in officially documented increased serum concentrations of these medicines.
  • Effect Reduced: Co-use with Anti-hypertensives (ACE inhibitors, ARBs) and Diuretics may result in a reduction of their intended therapeutic effects.
  • Nephrotoxicity Risk: Combination with agents like Ciclosporin and Tacrolimus is associated with an increased potential for kidney-related toxicity.

Timing and Population Notes

A time-separation rule exists, stating that use of this medicine is not recommended for 8–12 days following the administration of Mifepristone. Furthermore, the co-administration with Anti-hypertensives presents an increased risk of acute renal insufficiency for elderly or volume-depleted patients. Close medical surveillance is advised for individuals who consume alcohol regularly due to an increased risk of gastric bleeding.

Mechanism of Action

Ikappa Balpha and NF-kappa B Pathway Modulation

Bristaflam operates at the intracellular level. Its active component, Flama-A, is internalized and targets the Ikappa Balpha (Inhibitor of NF-kappa B) complex.

Bristaflam binds allosterically at the Ikappa Balpha site, which modifies the conformation of the complex and stabilizes the interaction between Ikappa Balpha and the NF-kappa B transcription factor. This action prevents the phosphorylation and subsequent ubiquitination of Ikappa Balpha, inhibiting its degradation. As a result, the NF-kappa B complex remains sequestered in the cytoplasm.

The restricted nuclear translocation of NF-kappa B modulates the NF-kappa B pathway, resulting in the modulation of inflammatory cytokine production. This process impacts pathways involved in bone and joint tissue homeostasis, which influences inflammatory effects on structural integrity.

Dosage and Administration Information

How to Use Bristaflam

The administration of Bristaflam (Aceclofenac) follows established clinical protocols to ensure consistent and controlled use. The general approach follows the core guidelines for Non-Steroidal Anti-Inflammatory Drugs (NSAIDs): to use the lowest effective dose for the shortest duration necessary to manage symptoms. The continued necessity of treatment is subject to periodic re-evaluation.


Administration Protocol

Usage Parameter Standard Protocol
Route of Administration Oral administration as a film-coated tablet.
Standard Adult Dose The maximum daily dose is 200 mg. This is taken as two separate 100 mg doses per day.
Timing & Preparation The tablet must be swallowed whole with a sufficient quantity of liquid, and should not be crushed or chewed. Ingestion is recommended with or after food.
Use in Older Adults No dose modification is typically required for the elderly, though the lowest dose principle must be maintained.
Dose Adjustments An initial daily dose of 100 mg is suggested for patients with mild hepatic impairment. Use in children under 18 is not recommended due to insufficient clinical data.
Handling Missed Doses If a dose is missed, a double dose should not be taken; the next dose is taken at the usual scheduled time.

These parameters define the standardized, high-level approach for administering Aceclofenac, covering the maximum permissible dosing, frequency, and specific physical requirements for tablet intake.

Recent Clinical Evidence

Research Evidence / Overview of Studies for Bristaflam

The research base for Bristaflam (Aceclofenac) consists primarily of controlled clinical trials, including randomized studies and meta-analyses, which contribute to the contextualization of how symptoms change in groups of patients with certain conditions. This evidence describes group patterns under specific research conditions and does not determine whether an individual will respond similarly.

Research Evidence for Osteoarthritis and Related Joint Conditions

Research has explored Osteoarthritis (OA), a condition characterized by functional limitations. The majority of evidence comes from short-term, randomized controlled trials (RCTs) and systematic reviews that compile these findings. These trials monitored patient-reported outcomes evaluating changes in pain intensity and functional outcomes related to daily activity level. Findings describe patterns observed in the studies related to measured changes in pain compared to placebo or other NSAIDs.

Research Evidence for Rheumatoid Arthritis and Ankylosing Spondylitis

For conditions involving periods of heightened symptoms such as Rheumatoid Arthritis (RA) and Ankylosing Spondylitis (AS), research examined how symptoms evolved in the observed populations. These studies were primarily controlled comparative trials and RCTs that explored short-term symptom patterns. They monitored outcomes linked to inflammatory states, such as the number of swollen or tender joints and changes in functional capacity scores. The research provides context but not individual predictions regarding long-term effects on disease progression.

Research Evidence for Acute and Chronic Musculoskeletal Pain

The evidence base here includes randomized, double-blind trials where measured pain reduction was a primary focus. These studies explored short-term symptom changes, monitoring outcomes related to physical discomfort. Research describes measurable changes in pain intensity and functional disability scores in adult patients with acute pain episodes. A key limitation is that the follow-up durations were very short, sometimes ten days or less.

What Remains Uncertain About Bristaflam Research

Reviewers have noted several areas where the evidence quality varies across studies. The primary limitations include the short duration of many core symptomatic trials, which means long-term effects are not fully established. Furthermore, subgroup findings are uncertain due to limited information for certain patient groups.
