Pharmacological properties

Diclofenac has anti-inflammatory, analgesic and antipyretic effects. By indiscriminately inhibiting cyclooxygenase 1 and 2, it disrupts the metabolism of arachidonic acid and reduces the amount of prostaglandins at the site of inflammation. In rheumatic diseases, the anti-inflammatory and analgesic effect of diclofenac helps to significantly reduce the severity of pain, morning stiffness, and swelling of the joints, which improves the functional state of the joint. For injuries, in the postoperative period, diclofenac reduces pain and inflammatory swelling.

It has been established that the drug has a strong analgesic effect in moderate to severe pain syndrome. In the presence of inflammation, caused, for example, by injury or surgery, the drug quickly eliminates both spontaneous pain and pain during movement, and also reduces inflammatory swelling of tissues and swelling in the area of ​​​​the surgical wound.


The time to reach the maximum concentration when administered intramuscularly at a dose of 75 mg is 15-30 minutes, the value of the maximum concentration is 1.9-4.8 (on average 2.7) mcg/ml. 3 hours after administration, the plasma concentration averages 10% of the maximum.

Communication with plasma proteins is more than 99% (most of it is associated with albumin).

Diclofenac penetrates into the synovial fluid, where maximum concentrations are measured 2 to 4 hours after peak plasma values ​​are reached. The apparent half-life from synovial fluid is 3 to 6 hours. Two hours after peak plasma values ​​are reached, concentrations of the active substance are higher in synovial fluid than in plasma and remain high for up to 12 hours.

Metabolism occurs as a result of multiple or single hydroxylation and conjugation with glucuronic acid. The enzyme system P450 CYP2C9 takes part in the metabolism of the drug. The pharmacological activity of the metabolites is lower than that of diclofenac.

Systemic clearance is 350 ml/min, volume of distribution is 550 ml/kg. The half-life from plasma is 2 hours. 65% of the administered dose is excreted in the form of metabolites by the kidneys; less than 1% is excreted unchanged, the rest of the dose is excreted as metabolites in the bile.

In patients with severe renal failure (creatinine clearance less than 10 ml/min), the excretion of metabolites in bile increases, but no increase in their concentration in the blood is observed.

In patients with chronic hepatitis or compensated liver cirrhosis, the pharmacokinetic parameters of diclofenac do not change.

Diclofenac passes into breast milk.

  • hematopoietic disorders,
  • hemostasis disorders (including hemophilia),
  • pregnancy,

With caution : coronary heart disease, cerebrovascular diseases, congestive heart failure, arterial hypertension, significant decrease in circulating blood volume (including after major surgery), edema syndrome, peripheral arterial disease, dyslipidemia, diabetes mellitus, anemia, bronchial asthma , renal failure (creatinine clearance less than 60 ml/min), alcoholism, erosive and ulcerative diseases of the gastrointestinal tract without exacerbation, history of liver disease, diverticulitis, condition after major surgical interventions, inducible porphyria, old age, smoking, severe somatic diseases , systemic connective tissue diseases, long-term use of non-steroidal anti-inflammatory drugs, simultaneous use of glucocorticosteroids, anticoagulants, antiplatelet agents, selective serotonin reuptake inhibitors, hyperlipidemia, the presence of Helicobacter pylori infection.


Drug interactions

Increases plasma concentrations of digoxin, methotrexate, lithium and cyclosporine.

Reduces the effect of diuretics; against the background of potassium-sparing diuretics, the risk of hyperkalemia increases; against the background of anticoagulants, thrombolytic agents (alteplase, streptokinase, urokinase) – the risk of bleeding (usually from the gastrointestinal tract).

Reduces the effects of antihypertensive and hypnotic drugs.

Increases the likelihood of side effects of other nonsteroidal anti-inflammatory drugs and glucocorticosteroids (bleeding in the gastrointestinal tract), methotrexate toxicity and cyclosporine nephrotoxicity.

Acetylsalicylic acid reduces the concentration of diclofenac in the blood. Concomitant use with paracetamol increases the risk of developing nephrotoxic effects of diclofenac.

Anticoagulants. Although clinical studies have not established the effect of the drug on the action of anticoagulants, there are reports of an increased risk of bleeding in patients taking diclofenac and these drugs simultaneously. Therefore, in the case of such a combination of drugs, careful and regular monitoring of patients is recommended.

Antidiabetic drugs. Clinical studies have shown that the drug can be used in conjunction with oral antidiabetic agents and will not change their therapeutic effect. However, there are isolated reports of the development of both hypoglycemia and hyperglycemia, which forced changes in the dose of glucose-lowering drugs during use of the drug.

Cefamandole, cefoperazone, cefotetan, valproic acid and plicamycin increase the incidence of hypoprothrombinemia.

Cyclosporine and gold preparations increase the effect of diclofenac on the synthesis of prostaglandins in the kidneys, which increases nephrotoxicity.

Simultaneous administration with ethanol, colchicine, corticotropin, selective serotonin reuptake inhibitors, and St. John’s wort preparations increases the risk of bleeding in the gastrointestinal tract.

Diclofenac enhances the effect of drugs that cause photosensitivity.

Drugs that block tubular secretion increase the plasma concentration of diclofenac, thereby increasing its toxicity.

Antibacterial drugs from the quinolone group – the risk of developing seizures.


special instructions

Patients using the drug must refrain from activities that require increased attention and rapid mental and motor reactions, and alcohol consumption.

Caution is necessary when prescribing the drug to patients with hepatic porphyria, since the drug can provoke attacks of porphyria.

Since prostaglandins play an important role in maintaining renal blood flow, special caution is required when treating patients with impaired cardiac or renal function, elderly patients, patients receiving diuretics, and patients who have a significant decrease in circulating plasma volume of any etiology, for example , in the period before and after massive surgical interventions. In such cases, during use of the drug, as a precaution, regular monitoring of renal function is recommended.

After discontinuation of the drug, renal function is usually restored to its original level.

The use of the drug for all of the above indications is usually limited to a few days. However, if, despite the recommendations for use, the drug is used for an extended period of time, it is recommended, as with long-term use of other NSAIDs, to monitor the composition of the peripheral blood.

The drug, like other NSAIDs, may temporarily inhibit platelet aggregation. Therefore, careful appropriate laboratory monitoring is necessary in patients with hemostasis disorders.

Based on generally accepted approaches, the drug should be used with caution in elderly patients. This is especially true in frail or low-weight elderly people; they are recommended to prescribe the drug at the minimum effective dose.
