Form Oral, Film-coated tablets
Pharmacological class Nonsteroidal Anti-Inflammatory Drug (NSAID)
General purpose Relief of pain, inflammation, and fever
Origin Synthetic (Phenylacetic acid derivative)

What is Deflamat DRS and its Pharmacological Classification?

Deflamat DRS is a specific medicinal preparation containing Diclofenac Potassium, a potent, synthetic substance utilized for its capacity to reduce symptoms related to inflammation. It is classified as a Nonsteroidal Anti-Inflammatory Drug (NSAID), a pharmacological category used for its anti-inflammatory effects. This designation indicates the drug's function is to control the body’s inflammatory processes, differentiating it from simple analgesics.

Deflamat DRS Composition and Form

The preparation features Diclofenac Potassium as its active ingredient, formulated as oral, film-coated tablets intended for systemic absorption throughout the body. The use of the potassium salt is intended to promote rapid dissolution and absorption when compared to the sodium salt form. This characteristic contributes to a prompt onset of symptomatic relief, allowing the medication's therapeutic effect to begin without undue delay.

General Purpose and Core Benefits

The general purpose of Deflamat DRS is to provide relief from physical discomfort driven by inflammatory states, specifically managing pain, inflammation, and fever. The medication achieves this by suppressing the creation of prostaglandins, which are local chemical messengers that signal pain and promote swelling. By controlling this biochemical process, the drug delivers a triple action: a robust analgesic (pain-relieving), a systemic anti-inflammatory (swelling-reducing), and an antipyretic (fever-reducing) effect.

What side effects are possible with Deflamat DRS?

Possible Side Effects and Safety Information

Deflamat DRS (Diclofenac Potassium), a Nonsteroidal Anti-Inflammatory Drug (NSAID), has an official safety profile categorized by System-Organ Class and frequency as documented by regulatory authorities. The most frequently reported adverse reactions are related to the Gastrointestinal (GI) System, classified as common (affecting ge 1 in 100 people). These may include abdominal pain, dyspepsia, nausea, vomiting, or diarrhea. Less common but officially documented effects include dizziness and headache.


Serious Adverse Reactions and Safety Patterns

The regulatory label highlights several serious risks, which can be fatal. These include Cardiovascular Thrombotic Events (such as myocardial infarction and stroke) and Serious GI Events (including bleeding, ulceration, and perforation of the stomach or intestines). These severe events can occur at any time during treatment, with the risk stated to increase with duration of use and high dose.

Other rare but serious documented effects involve the Hepatobiliary System (hepatitis, liver failure) and the Renal and Urinary System (acute kidney failure), as well as Serious Skin Reactions (like Stevens-Johnson Syndrome) and Anaphylactic Reactions.


Population-Specific Safety Considerations

The official label documents specific safety constraints for certain groups. Older adults are noted to have a greater risk for serious gastrointestinal adverse events. Use is contraindicated in patients with severe, uncompensated heart failure, severe renal or hepatic failure, and for the treatment of perioperative pain following Coronary Artery Bypass Graft (CABG) surgery. Additionally, use is strictly contraindicated starting in the third trimester of pregnancy.

Overdose and Emergency Response

Overdose and When to Seek Help

Overdosage with Deflamat DRS (diclofenac) can lead to a range of clinical manifestations, and immediate medical attention is required for any suspected incident.

Documented Overdose Presentations

Symptoms following an acute overdose are not always observed immediately and there is no typical clinical picture. Reported symptoms may include:

  • Gastrointestinal Effects: Nausea, vomiting, diarrhea, epigastric pain, and gastrointestinal bleeding.
  • Central Nervous System Effects: Headache, dizziness, ringing in the ears (tinnitus), and convulsions (seizures).
  • Severe Systemic Risks: Significant poisoning can lead to severe organ damage, including acute renal failure and liver damage. Hypotension (low blood pressure) may also occur.

Required Emergency Actions

Seek medical attention immediately for any suspected overdose. Emergency treatment is primarily supportive and symptomatic, focusing on managing complications such as renal failure, hypotension, convulsions, and gastrointestinal irritation.

Regulatory guidance suggests that activated charcoal may be considered for administration within one hour of ingesting a potentially toxic amount. Measures like forced diuresis, haemodialysis, or haemoperfusion are generally considered unlikely to be beneficial due to the drug's high protein binding. Patients with pre-existing kidney damage are at an increased risk of convulsions following significant poisoning.

Eligibility and Restrictions for Use

Official Population Eligibility for Deflamat DRS (Diclofenac Potassium)

The eligibility to use Deflamat DRS is defined by official regulatory documents, strictly classifying individuals who are permitted, restricted, or absolutely prohibited from using the medicine. Use is generally established for adults and for pediatric patients 12 years of age and older for certain formulations.

Contraindicated Populations (Must Not Use) Condition-Based Restrictions (Use with Caution)
Known hypersensitivity to diclofenac or any NSAID (including aspirin-sensitive asthma). Patients with hepatic impairment or mild to moderate renal impairment (requires close monitoring).
Treatment of perioperative pain in the setting of Coronary Artery Bypass Graft (CABG) surgery. Patients with history of GI ulceration or bleeding (use lowest dose).
Active GI ulceration, bleeding, or perforation. Elderly patients (increased risk; use lowest effective dose).
Severe heart, hepatic, or renal failure. Women of reproductive potential trying to conceive (may affect ovulation).

Eligibility is also determined by developmental status: the medication is contraindicated in women starting at 30 weeks gestation (third trimester) and is generally not recommended for women who are breastfeeding/lactating.

What should I know about interactions with other medicines?

Interactions with other medicines and products

Official regulatory information describes several clinically significant interaction patterns for Deflamat DRS (Diclofenac Potassium), focusing on potential pharmacokinetic changes, pharmacodynamic additive effects, and altered substance clearance.

Pharmacokinetic and Exposure Interactions

Co-administration with CYP2C9 Inhibitors, such as Voriconazole, is documented to increase the plasma exposure (Cmax and AUC) of Diclofenac. Conversely, CYP2C9 Inducers (e.g., Rifampin) may reduce Diclofenac concentrations. Diclofenac also inhibits the tubular renal clearance of substances like Methotrexate, which can elevate Methotrexate serum levels. Furthermore, Diclofenac is documented to increase the plasma levels of Lithium and Digoxin by reducing their clearance, leading to potential toxicity concerns.

Pharmacodynamic and Risk Interactions

The combination of Deflamat DRS with other systemic NSAIDs or Aspirin at analgesic doses is restricted in regulatory documents due to an additive risk of serious gastrointestinal events. An increased risk of bleeding is also noted with Anticoagulants (e.g., Warfarin) and Selective Serotonin Reuptake Inhibitors (SSRIs). For Antihypertensive Agents (e.g., ACE Inhibitors, ARBs), co-administration may diminish their intended blood pressure-lowering effect. Caution is noted when combining with ACE Inhibitors/ARBs in specific populations, such as the elderly, volume-depleted, or renal-impaired patients, due to an increased risk of renal function deterioration.

Mechanism of Action

How Deflamat DRS Works

Deflamat DRS (Diclofenac Potassium) exerts its effect by directly targeting and modulating the body's molecular signaling pathways involved in heightened physiological responses. The rapid absorption, facilitated by the potassium salt, achieves accelerated systemic concentrations necessary for this modulation.

Molecular Targeting of Cyclooxygenase Enzymes

The core mechanism involves the competitive inhibition of the Cyclooxygenase (COX) enzymes (COX-1 and COX-2). This interaction blocks the active site and prevents COX from converting arachidonic acid into prostanoids. By suppressing this biochemical step, the drug alters the production of key mediators like Prostaglandins (PGE2) that are involved in physiological signaling cascades.

️ Causal Cascade: From Molecular Blockade to Physiological Effect

This molecular blockade results in a dual action: peripheral and central. Peripherally, the reduction of PGE2 at the site decreases the sensitization of nerve endings and limits alterations in local vascular dynamics. Centrally, the suppression of PGE2 in the hypothalamus affects the central thermoregulatory setpoint, leading to the initiation of heat dissipation mechanisms.

️ Mechanistic Constraints on Physiological Regulation

The drug's mechanism includes the inhibition of COX enzymes that produce regulatory prostaglandins (PGE2, PGI2) involved in organ system regulation, particularly in the kidneys. This inherent constraint on the mechanism affects the body's ability to maintain renal blood flow and glomerular filtration rate in states of volume depletion or altered systemic perfusion.

Dosage and Administration Information

Deflamat DRS (Diclofenac Potassium) is intended solely for oral administration (by mouth). The film-coated tablets are swallowed whole with a liquid and are not intended to be crushed, broken, or chewed. Administration with or after food is utilized to help mitigate potential gastrointestinal irritation, which defines the typical administration context.


The standard adult dosing regimen is typically administered in divided doses two or three times daily. The total daily dosage generally ranges from 75 mg to 150 mg. For most applications, the maximum recommended daily dose is 150 mg, which defines the ceiling for the administered quantity. A missed dose is generally skipped if the next scheduled dose is approaching, rather than taking extra medicine to compensate.


The therapeutic approach follows the principle of using the lowest effective dose for the shortest possible duration required for symptomatic control. This principle applies to both short-term use for acute conditions and management protocols for chronic states. For older adults (elderly), treatment is initiated and maintained at the lowest effective dose due to increased sensitivity. The 50 mg tablet formulation is not generally recommended for use in children under 14 years of age.
