Overview of Cataflam

What is Cataflam? Definition and Classification

Property Description
Active Ingredient Diclofenac potassium
Form Immediate-release tablet
Pharmacological Class Nonsteroidal Anti-inflammatory Drug (NSAID)
General Purpose Pain, inflammation, and fever relief
Origin Synthetic (Benzeneacetic acid derivative)

Identity, Classification, and Composition

Cataflam is a distinct single-ingredient pharmaceutical preparation classified as a Nonsteroidal Anti-inflammatory Drug (NSAID). The drug's core medicinal activity comes from its active ingredient, diclofenac potassium, a synthetic compound belonging to the benzeneacetic acid derivative family. This formulation, typically supplied as an immediate-release tablet for oral administration, is specifically engineered to provide a rapid onset of action.

The specific use of the potassium salt in Cataflam is a key characteristic that sets it apart from preparations containing the sodium salt (Diclofenac Sodium) of the same active moiety, allowing for quicker dissolution and absorption in the gastrointestinal tract. This difference in formulation is clinically recognized for addressing acute pain states where speed of relief is critical.


General Purpose and High-Level Action

The general purpose of Cataflam is to deliver comprehensive relief from physical discomfort by exerting its triple physiological actions: analgesic (pain relieving), anti-inflammatory (reducing swelling), and antipyretic (fever reducing) effects. It achieves this by functioning as a potent inhibitor of cyclooxygenase (COX) enzymes, thereby blocking the synthesis of prostaglandins. These prostaglandins are the chemical messengers responsible for triggering pain, swelling, and fever.

Diclofenac is an established anti-inflammatory agent used systemically. The drug is a recognized tool for combating inflammation and its associated symptoms. This multi-action mechanism enables the medication to effectively reduce the perception of pain, mitigate inflammatory response symptoms, and help normalize an elevated body temperature.

What side effects are possible with Cataflam?

Possible Side Effects and Safety Information

Cataflam (diclofenac potassium) is a nonsteroidal anti-inflammatory drug (NSAID) whose use is associated with a risk of serious adverse events that may be fatal, as outlined in official regulatory warnings.

Serious Adverse Reactions (Boxed Warnings)

  • Cardiovascular Thrombotic Events: Use of Cataflam may increase the risk of serious, potentially fatal, cardiovascular thrombotic events, including myocardial infarction (MI) and stroke. This risk can increase with the duration of use and may be higher in patients with pre-existing heart disease or risk factors. Cataflam is contraindicated for the treatment of peri-operative pain in the setting of coronary artery bypass graft (CABG) surgery.
  • Gastrointestinal Events: NSAIDs, including Cataflam, increase the risk of serious gastrointestinal adverse events, such as bleeding, ulceration, and perforation of the stomach or intestines. These events can occur without warning symptoms and may be fatal, particularly in elderly patients.

Other Clinically Significant Risks

  • Hepatotoxicity and Renal Effects: The medication may cause liver damage (hepatotoxicity), including rare cases of severe liver failure, and can lead to new or worsening kidney problems (renal toxicity), including acute kidney injury. Fluid retention and edema have been observed, and blood pressure should be monitored as NSAIDs may lead to new hypertension or worsen existing hypertension.
  • Hypersensitivity and Skin Reactions: Serious allergic reactions (anaphylactoid reactions) and severe, sometimes fatal, skin reactions (e.g., Stevens-Johnson Syndrome, Toxic Epidermal Necrolysis) have been reported. Cataflam is contraindicated in patients with a history of asthma, hives, or allergic-type reactions to aspirin or other NSAIDs.

Common Side Effects

The most commonly reported adverse reactions include gastrointestinal disturbances such as nausea, abdominal pain, diarrhea, constipation, and dyspepsia. Other common effects include headache, dizziness, and edema (swelling).

Population-Specific Considerations

  • Pregnancy: Use is generally avoided from 20 weeks gestation, and is contraindicated in the third trimester due to the risk of fetal renal dysfunction and premature closure of the fetal ductus arteriosus.
  • Elderly: Older patients are at a greater risk for serious gastrointestinal adverse events compared to younger patients.

Overdose and Emergency Response

Overdose and When to Seek Help

Official regulatory information regarding an overdose of Cataflam (diclofenac potassium) focuses strictly on documented clinical manifestations and mandated emergency actions. Overdose may present with documented signs including nausea, vomiting, epigastric pain, headache, drowsiness, and dizziness. More severe outcomes officially described include the potential for acute renal failure, gastrointestinal bleeding or perforation, and serious cardiovascular thrombotic events, such as myocardial infarction or stroke.

Regulators mandate that individuals seek medical help right away or get emergency medical help immediately if an overdose is suspected. Urgent attention is required if symptoms involve severe effects like slurred speech, shortness of breath, or vomiting blood or material resembling coffee grounds. Gastrointestinal complications are documented as having more serious consequences in the elderly.

No specific antidote is known for diclofenac overdose. Management is officially described as symptomatic and supportive treatment. This may involve procedures such as the administration of activated charcoal to limit absorption and the close monitoring of vital signs.

Therapeutic Uses of Cataflam

Cataflam is commonly used to help with symptoms related to physical discomfort and inflammatory states. The medication is relevant when supportive symptom management is appropriate, offering supportive therapeutic benefit.

The medication is commonly used to help with several clusters of symptoms across different therapeutic contexts. These indications include symptomatic support for primary dysmenorrhea (menstrual cramps), migraine attacks, and is considered relevant for easing the signs and symptoms of osteoarthritis and rheumatoid arthritis. It is also commonly used in scenarios where short-term symptomatic assistance is needed following post-traumatic injuries like sprains and strains, or after minor procedures.

“The medication is commonly applied in clinical settings that involve acute or disruptive symptom patterns.”


Quick Fact: Management for Pain, Swelling, and Stiffness

Cataflam generally contributes to easing the overall symptom load during periods of heightened symptoms. It is applied when appropriate and is considered relevant for easing symptoms related to pain, swelling, and stiffness. It may help patients cope more steadily with symptom fluctuations when chronic conditions become more noticeable. This supportive action may help maintain a sense of stability during episodes of acute discomfort.

Eligibility and Restrictions for Use

The use of Cataflam (diclofenac potassium) is strictly governed by regulatory eligibility rules based on a patient’s health status and age. The drug is generally intended for adults and adolescents 14 years of age and older, but use in children under this age is generally not recommended or established for the immediate-release tablet form.

Contraindicated Populations

The medicine must not be used by patients who fall into the following regulatory-defined categories:

  • Hypersensitivity: Those with a known history of severe allergic reactions (e.g., asthma, urticaria) to diclofenac, aspirin, or any other NSAID.
  • Severe Organ Failure: Patients with severe hepatic failure or severe renal failure (GFR <15 mL/min/1.73m^2)
  • Gastrointestinal Risk: Individuals with active gastrointestinal ulceration, bleeding, or perforation.
  • Cardiovascular: Patients with established congestive heart failure (NYHA Class II-IV) or who are in the peri-operative setting of Coronary Artery Bypass Graft (CABG) surgery.
  • Pregnancy: Use is absolutely contraindicated during the last trimester of pregnancy (at or after 30 weeks gestation).

Conditional and Restricted Use

Use requires caution and is often subject to strict limitations in older adults and patients with mild to moderate hepatic or renal impairment. Furthermore, use is not recommended in women who are breastfeeding.

What should I know about interactions with other medicines?

The official regulatory profile for Cataflam (diclofenac potassium) documents several clinically significant interactions, classified by their pharmacokinetic or pharmacodynamic outcomes. Co-administration with other Nonsteroidal Anti-inflammatory Drugs (NSAIDs) or Aspirin is generally restricted due to the heightened, additive risk of serious gastrointestinal adverse events. High-risk combinations also include oral anticoagulants, antiplatelet agents, and Selective Serotonin Reuptake Inhibitors (SSRIs), which increase the documented potential for hemorrhage.

The medicine's exposure is sensitive to the CYP2C9 enzyme system. Potent CYP2C9 inhibitors, such as voriconazole, increase diclofenac plasma concentrations, while inducers, like rifampin, may decrease them. Cataflam is documented to reduce the renal clearance of both Lithium and Methotrexate, which results in increased plasma concentrations of these co-administered medicines.

Pharmacodynamic interactions include the potential to decrease the antihypertensive effect of ACE Inhibitors and ARBs, and lessen the natriuretic effect of diuretics. Co-administration with Cyclosporine or Tacrolimus increases the documented risk of nephrotoxicity. For agents such as Cholestyramine, the official labeling requires a separation of administration by four to six hours to prevent reduced absorption. Interaction severity is noted as being of greater clinical significance in elderly patients and those with pre-existing renal impairment.

Mechanism of Action

The pharmacological effect of Cataflam (Diclofenac potassium) is governed by a precise engagement with core biological pathways, leading to the engagement with pathways that control specific physiological responses. Its mechanism operates across three principal domains.

Molecular Blockade of Cyclooxygenase (COX) Enzymes

This domain focuses on the primary biological targets: the Cyclooxygenase-1 (COX-1) and Cyclooxygenase-2 (COX-2) enzymes. The drug functionally blocks these enzyme active sites, immediately suppressing the conversion of arachidonic acid into pro-inflammatory mediators like prostaglandins. This action is the foundational molecular step leading to subsequent physiological effects.

Modulation of Peripheral Inflammatory Signaling

By substantially reducing prostaglandin synthesis at the site of tissue irritation, the drug's mechanism intervenes in the inflammatory cascade. This results in the reduction of peripheral nociceptive signaling and reduces the localized vascular responses, such as vasodilation and increased permeability, directly interfering with the concentration of chemical mediator activity on nerve fibers and blood vessels.

Central Thermoregulatory Adjustment

A distinct mechanistic action occurs centrally within the hypothalamus. The same COX inhibition mechanism limits the production of PGE2 in the brain, a key molecule responsible for elevating the body’s thermal set-point. This allows for the lowering of the hypothalamic temperature set-point, aligning the overall effect profile with the resulting systemic physiological effects.

Dosage and Administration Information

Official Administration Guidelines

Cataflam (diclofenac potassium immediate-release tablets) is administered strictly via the oral route. Standard use protocols center on two core principles: using the lowest effective dose and limiting treatment to the shortest duration possible.


Dosing and Scheduling

Administration is defined by condition-specific numerical dose ranges and must be taken in divided doses multiple times per day (e.g., two to four times daily), as opposed to a single daily dose. The total daily intake typically ranges from 100 mg to 200 mg, depending on the specified condition, with strict adherence to the maximum daily limit. For example, the total daily dosage for conditions such as osteoarthritis is generally 150 mg or less, while some conditions permit up to 200 mg.


Administration Specifics

  • Intake: The tablets must be swallowed whole with liquid. They should not be crushed or chewed.
  • Food Relationship: The medication may be taken with or without food. Taking it with food may result in a delay in the onset of action, but it does not significantly impact the overall extent of absorption.
  • Concomitant Use: General guidelines advise against the concurrent use of Cataflam with other Nonsteroidal Anti-inflammatory Drugs (NSAIDs).

Population-Specific Rules

  • Older Adults: Administration requires caution, and the lowest effective dose should be used for the briefest duration possible.
  • Pediatrics: The drug is not generally recommended for use in children under 14 years of age for systemic anti-inflammatory indications.

Recent Clinical Evidence

Research Evidence / Overview of Studies for Cataflam


Evidence for Use in Acute Pain States

Research exploring the study landscape for Cataflam (diclofenac potassium) for acute pain includes short-term, randomized controlled trials (RCTs) and single-dose studies. These studies were used in research exploring how symptoms change over time and were conducted during periods of increased symptom activity, such as following minor procedures or in acute post-traumatic injury. The research examined outcomes related to physical discomfort in studies that involved short observation intervals, typically ranging from a single dose up to a few days. Findings describe patterns observed in these studies, reporting measured changes in pain intensity between the compound and the comparison group. Long-term functional outcomes following post-traumatic events appear not to be fully established by the existing evidence. Results apply only to the specific, generally healthy adult populations studied.


Evidence for Use in Primary Dysmenorrhea and Acute Migraine

The evidence for primary dysmenorrhea (menstrual cramps) was evaluated in specialized, double-blind, placebo-controlled crossover studies designed to assess fluctuating symptoms. Studies examined outcomes reflecting daily functioning during the acute symptomatic phase. For acute migraine attack, research examined temporary physiological imbalance. Trials evaluated the compound in settings associated with acute episodes, and data show patterns related to the measurement of a pain-free state and the reporting of changes in associated symptoms. The evidence for both conditions was studied in the acute phase. Follow-up durations were limited, and research is restricted to the treatment of a single attack, providing no insight into long-term management.


Evidence for Use in Chronic Inflammatory Conditions and Special Populations

Cataflam was evaluated in conditions characterized by fluctuating symptoms, such as osteoarthritis and rheumatoid arthritis. Research explored short-term symptom changes using randomized controlled trials, monitoring outcomes linked to inflammatory states, including joint pain and stiffness. The evidence for use in chronic conditions explores limited follow-up durations, with most treatment periods lasting only up to 30 days. Research has also evaluated the compound in specific populations, such as pediatric subjects, primarily through pharmacokinetic (PK) studies that focus on how the medicine is processed by the body, rather than large-scale efficacy trials. Data for certain groups, such as older adults, often remain insufficient within the primary efficacy trials.
