What is Dicloreum and What Type of Medicine is It?

Dicloreum is a widely recognized trade name for a medicinal product featuring the active substance Diclofenac, a fully synthetic organic compound. It is formally classified as a Nonsteroidal Anti-inflammatory Drug (NSAID), belonging to the chemical subgroup of acetic acid derivatives. Diclofenac is used for its ability to reduce inflammation. As an NSAID, Dicloreum's function is to systematically modulate the body's response to discomfort, establishing its role as a multifaceted agent for addressing both pain and the underlying inflammatory process.


Diclofenac: Composition and Available Forms

The core chemical entity providing the therapeutic effect is Diclofenac, which is typically incorporated into products as its salt forms: Diclofenac sodium or Diclofenac potassium. The product is made available in a variety of high-level dosage forms, encompassing oral solid forms such as tablets and capsules, parenteral solutions for injection, and topical preparations like gels and medicated plasters. Dicloreum is often positioned in the market for general inflammatory conditions in adults. The flexibility in its forms allows for varied routes of administration—either systemic absorption or focused local treatment.


What is the General Purpose of Dicloreum?

The general purpose of Dicloreum is to alleviate discomfort by providing a triple benefit: an analgesic (pain-relieving) effect, an anti-inflammatory effect, and an antipyretic (fever-reducing) effect. Diclofenac achieves this by inhibiting the body's synthesis of prostaglandins, which are key chemical substances that trigger pain signals and inflammation. The mechanism involves the non-selective inhibition of cyclooxygenase enzymes, which reduces prostaglandin levels in inflamed tissues. This targeted action makes the product suitable for managing general physical discomfort associated with inflammatory processes.

What side effects are possible with Dicloreum?

Possible Side Effects and Safety Information

Official regulatory documents classify the safety profile of Dicloreum (diclofenac) based on the severity and frequency of possible adverse reactions and specific usage restrictions.


Serious Warnings and Risks

The most significant documented risks involve the cardiovascular and gastrointestinal systems, which can be potentially fatal.

  • Serious Cardiovascular Thrombotic Events: Use of this medicine increases the risk of serious, potentially fatal, cardiovascular thrombotic events, including myocardial infarction (heart attack) and stroke. This risk may increase with higher doses (e.g., 150 mg daily) and longer duration of use.
  • Serious Gastrointestinal Adverse Events: Regulatory information specifies the risk of serious gastrointestinal events, including inflammation, bleeding, ulceration, and perforation of the stomach or intestines, which can occur without warning and be fatal.
  • Organ Toxicity: Potential for serious, sometimes fatal, hepatic (liver) injury, and new or worsening renal (kidney) failure or injury is documented.

Safety Restrictions and Limitations

Specific restrictions and warnings limit the use of this medicine in certain populations or circumstances:

  • Contraindications: It is contraindicated in patients with established congestive heart failure (NYHA Class II-IV), ischemic heart disease, peripheral arterial disease, cerebrovascular disease, or immediately before or after coronary artery bypass graft (CABG) surgery.
  • Dose/Duration: To mitigate risk, treatment should use the lowest effective dose for the shortest duration necessary to achieve the desired effect.
  • Pregnancy: Contraindicated in the late stages of pregnancy (after 20 weeks) due to the risk of fetal renal dysfunction.

Adverse Reaction Classification

Reported adverse reactions range from common events (such as nausea, headache, dizziness) to uncommon and rare but more serious organ-system effects spanning the Gastrointestinal, Cardiovascular, Renal, and Nervous systems, reflecting the systemic nature of the medicine's safety profile.

Overdose and Emergency Response

Overdose and When to Seek Help

Official regulatory documents describe the profile of Diclofenac (Dicloreum) overdose, noting that ingestion exceeding prescribed limits requires immediate attention due to the potential for severe consequences. The officially documented manifestations of overdose primarily involve the gastrointestinal and central nervous systems.

Overdose may present with epigastric pain, nausea, vomiting, and diarrhea. Central nervous system effects can include headache, drowsiness, dizziness, and tinnitus. More serious, regulator-listed outcomes include the potential for acute renal failure, hepatic dysfunction, and gastrointestinal bleeding.

Emergency Actions and Management

Immediate medical attention must be sought if an overdose is suspected or confirmed. Official guidance mandates contacting emergency services or a Poison Control Center due to the risk of life-threatening toxicity. Management is defined in regulatory labeling as symptomatic and supportive, as no specific antidote is known for Diclofenac.

Regulatory documents outline required procedures, which may include administering activated charcoal or gastric decontamination in cases of recent toxic ingestion. Close hospital monitoring of vital signs, renal function, and liver function is required for management, particularly given the documented potential for increased severity in patients with underlying hepatic or renal impairment.

Therapeutic Uses of Dicloreum

Dicloreum (Diclofenac) is relevant across multiple therapeutic domains primarily focused on alleviating symptoms related to physical discomfort and inflammatory or irritative states. It is considered relevant in supportive symptom management when pain and swelling create noticeable physiological strain.

Diclofenac is commonly used to help with symptoms related to arthritis, acute pain, and menstrual cramping. The medication is considered relevant for conditions characterized by periods of heightened symptoms.


It is used in situations involving certain distressing symptoms by easing distress and contributing to the overall symptom load. It is often applied during phases when symptoms become more noticeable, such as managing rheumatoid arthritis, osteoarthritis, sprains and strains, acute gouty arthritis flares, and primary dysmenorrhea.

“The medication may provide supportive relief, assisting with maintaining functional stability during periods of acute inflammation or discomfort.”


Quick Fact: Relief for Pain and Swelling

Dicloreum plays a role in managing symptoms associated with acute or disruptive episodes where short-term symptomatic assistance is needed. This includes addressing symptoms related to heightened physiological activity, such as fever (febrile conditions) present with general discomfort, or addressing localized swelling and pain following physical trauma or operative procedures.

Eligibility and Restrictions for Use

Dicloreum, which contains the active substance diclofenac, is an Non-Steroidal Anti-Inflammatory Drug (NSAID) used to manage pain and inflammation. It is generally suitable for most adults and, in certain formulations and indications (like juvenile idiopathic arthritis), may be prescribed to children, typically starting from 12 months of age, depending on the specific product and doctor’s guidance.


Who Should Avoid Dicloreum?

Diclofenac is not suitable for everyone. Individuals with the following conditions should generally avoid taking Dicloreum or use it only under strict medical supervision:

  • Allergy or Sensitivity: History of asthma, hives, or other allergic-type reactions after taking diclofenac, aspirin, or any other NSAID.
  • Gastrointestinal Issues: Active or a history of recurrent peptic ulcers, gastrointestinal bleeding, or perforation.
  • Cardiovascular Conditions: Established congestive heart failure (NYHA class II-IV), ischemic heart disease, peripheral arterial disease, or cerebrovascular disease. It is also contraindicated for pain relief before or immediately after Coronary Artery Bypass Graft (CABG) surgery due to an increased risk of serious cardiovascular events.
  • Pregnancy: Contraindicated during the last trimester of pregnancy (after 30 weeks) and generally advised to be avoided from 20 weeks gestation onward due to potential risks to the fetus, such as kidney problems or premature closure of the ductus arteriosus.
  • Severe Organ Impairment: Severe liver or kidney disease.

Patients with other risk factors, such as high blood pressure, diabetes, high cholesterol, or those who smoke, should have the potential benefits and risks carefully assessed by a healthcare professional before starting treatment. Older patients may also require special monitoring.

What should I know about interactions with other medicines?

Interactions with other medicines and products

This section outlines officially documented interaction patterns for Dicloreum (Diclofenac) as stated in government regulatory documents.


Pharmacodynamic and Pharmacokinetic Interactions

Interaction Type Interacting Substances Official Regulatory Outcome
Increased Bleeding Risk Anticoagulants, Antiplatelet drugs, SSRIs Co-administration elevates the risk of serious gastrointestinal bleeding.
Altered Drug Clearance Lithium, Methotrexate Diclofenac reduces the renal clearance of these medicines, potentially increasing their plasma concentration and risk of accumulation.
Reduced Efficacy Diuretics, ACE Inhibitors, ARBs Diclofenac may reduce the natriuretic and antihypertensive effects of these medicines. This combination also increases the risk of renal function deterioration, especially in elderly or volume-depleted patients.
Increased Exposure Voriconazole (a metabolic inhibitor) This co-administration results in a pharmacokinetic interaction that significantly increases Diclofenac's systemic exposure (AUC and Cmax), as documented in regulatory studies.

Interaction-Related Restrictions

Concomitant use with Aspirin (antithrombotic doses) and other systemic NSAIDs is officially discouraged or not recommended due to the confirmed additive risk of serious gastrointestinal adverse events. Furthermore, the consumption of alcohol is linked to an increased risk of serious gastrointestinal bleeding. For certain oral solution formulations, administration is specified to occur on an empty stomach because food is documented to reduce systemic absorption.

Mechanism of Action

Targeting the Cyclooxygenase (COX) Enzyme System

Dicloreum's core action is mediated by its active ingredient, diclofenac, which acts as a non-selective inhibitor of the Cyclooxygenase-1 (COX-1) and Cyclooxygenase-2 (COX-2) enzymes. This primary interaction blocks the enzyme active sites, preventing the conversion of the substrate, arachidonic acid, into various biologically active mediators.


Modulating the Prostaglandin Synthesis Cascade

Inhibiting the COX enzymes directly interrupts the Arachidonic Acid Cascade, resulting in a reduction in the cellular production of prostaglandins and other pro-inflammatory eicosanoids. This modification of the humoral signaling pathway is the mechanistic link that results in the observable physiological effects of decreased peripheral nociceptor excitability and reduced vascular fluid extravasation at tissue sites.


Physiological Modulation of Nociception and Thermoregulation

Mechanistic consequence involves the drug's influence across both peripheral and central pathways. The limitation of pro-inflammatory mediator activity contributes to the modulation of nociceptive signaling and the adjustment of the hypothalamic thermoregulatory set point within the targeted systems.

Dosage and Administration Information

How to Use Dicloreum: Administration Overview

Dicloreum (Diclofenac) is administered via multiple routes, selected based on the specific formulation and intended use, following the overarching principle of using the lowest effective dose for the shortest duration necessary. The primary routes include oral (tablets, capsules, powder), parenteral (intramuscular and intravenous injection), rectal (suppository), and topical (gel or patch).

Standard Dosage and Frequency

Systemic dosing regimens generally adhere to a maximum total daily dose of 150 mg for adults. For chronic inflammatory conditions like osteoarthritis, the typical oral maintenance dose is 100 mg to 150 mg per day, usually divided into two or three administrations. Extended-release formulations are typically administered as a single 100 mg once daily dose. Injectable forms (IM or IV) are generally restricted to a maximum duration of two days, followed by a transition to oral or rectal forms if continued treatment is required.

Administration Conditions and Handling

Administration requires adherence to specific handling instructions. Delayed-release tablets are to be swallowed whole and must not be crushed, chewed, or broken. Certain oral forms, such as capsules containing the diclofenac free acid and oral solution, must be taken on an empty stomach (one hour before or two hours after a meal) for optimal absorption. Intravenous solutions require immediate dilution with buffered 0.9% saline or 5% glucose prior to slow infusion. Dosing for elderly or renally/hepatically impaired patients may necessitate the use of the lowest effective dose.

Recent Clinical Evidence

Research Evidence / Overview of Studies

Examination of Outcomes in Osteoarthritis

Clinical studies have explored the treatment's role in the management of pain and function for individuals with osteoarthritis (OA), particularly in the knee and hip. A comprehensive meta-analysis indicated that diclofenac, compared to placebo, was consistently associated with improvements in pain and physical function scores (e.g., WOMAC) in elderly patients with knee OA.

In a review comparing various non-steroidal anti-inflammatory drugs (NSAIDs), high-dose oral diclofenac demonstrated outcomes that met the pre-specified minimal clinically important difference for both pain and function, suggesting a clinically relevant effect in this population. Topical formulations have also been extensively studied, with research reporting that patients treated with a diclofenac sodium gel achieved clinically meaningful relief that was often sustained for 12 weeks in knee OA trials.


Safety and Tolerability Profile

The treatment's safety and tolerability were assessed across the studies. Like all systemic NSAIDs, diclofenac's use is associated with risks that require careful evaluation by a healthcare provider. Studies have noted an increased risk of serious cardiovascular events, such as heart attack and stroke, particularly with high-dose and long-term use. This risk profile has led to updated recommendations from regulatory agencies, including contraindications for patients with established cardiovascular disease (e.g., congestive heart failure, ischaemic heart disease).

However, topical formulations are generally associated with significantly lower systemic exposure compared to oral forms, which often translates to a reduced incidence of systemic adverse events, including gastrointestinal issues.

Frequently Asked Questions (FAQ)

Common questions about Dicloreum (FAQ)

Q: How long does it take for Dicloreum to start working?

Dicloreum typically begins to relieve symptoms within 30 minutes to an hour. The full effect may typically be felt within 4 hours, though individual results can vary. If symptoms do not improve after 2 days, it may be appropriate to consult a healthcare provider for reevaluation.
