Description of the drug approved by the manufacturer for the printed edition of 2011.


Diclofenac is a non-steroidal anti-inflammatory drug (NSAID) with analgesic, anti-inflammatory and antipyretic effects.

The main mechanism of its action and associated side effects are indiscriminate inhibition of the activity of the enzyme cyclooxygenase 1 and 2 (COX1 and COX2), which leads to a disruption of the metabolism of arachidonic acid, a decrease in the synthesis of prostaglandins, prostacyclin and thromboxane.
The synthesis of prostaglandins in the kidneys, mucous membrane of the stomach and synovial fluid decreases.
The most effective for inflammatory pain.
In rheumatic diseases, the anti-inflammatory and analgesic effect of diclofenac significantly reduces the severity of pain, morning stiffness, swelling of the joints, which improves the functional state of the joints. In injuries, in the postoperative period, diclofenac reduces pain and inflammatory edema. Like all NSAIDs, diclofenac has antiaggregant activity. In therapeutic doses, diclofenac has virtually no effect on bleeding time. With prolonged treatment, the analgesic effect of diclofenac does not decrease.


Diclofenac is rapidly absorbed after rectal administration.
C max is reached after 1 hour. With rectal administration, eating does not affect the absorption of diclofenac.

99% of the absorbed diclofenac binds to plasma proteins, mainly albumins.
Diclofenac actively penetrates into the synovial fluid, where it reaches 60-70% of serum concentrations. After 3-6 hours after the application of the concentration of the active substance and metabolites in the synovial fluid is higher than in the serum.Diclofenac from synovial fluid is excreted more slowly than from serum.
Metabolism and excretion

T 1/2 of diclofenac is 1-2 hours.
Diclofenac is almost completely metabolized in the liver, mainly by hydroxylation and methoxylation. The enzyme system P450 CYP2C9 takes part in the metabolism of the drug. The pharmacological activity of metabolites is lower than that of diclofenac.
T 1/2 from the plasma - 2 hours.
About 70% of the administered dose is excreted as pharmacologically inactive metabolites by the kidneys; less than 1% is unchanged, the rest of the dose is excreted as metabolites with bile.
Pharmacokinetics in special clinical cases

In patients with severe renal failure (CC less than 10 ml / min), excretion of metabolites with bile is increased, while there is no increase in their concentration in the blood.

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


Diseases that require the achievement of a rapid anti-inflammatory or analgesic effect:

- inflammatory diseases of the musculoskeletal system (rheumatoid arthritis, seronegative spondylitis, juvenile chronic arthritis, arthritis of another etiology);

- degenerative diseases of the musculoskeletal system (osteoarthritis);

- microcrystalline arthritis (gouty arthritis, pseudo-arthritis arthritis);

- rheumatic soft tissue damage;

- periarthritis, bursitis, myositis, tendonitis, synovitis;

- other inflammatory diseases of the musculoskeletal system accompanied by pain syndrome.

As an analgesic, Naklofen is used in soft tissue injuries, in dentistry, after surgical interventions, in severe migraine attacks, primary algodismorrhea, adnexitis, as well as in renal or biliary colic.

Diclofenac is intended for symptomatic therapy and does not affect the progression of the disease.


If patients with oral diclofenac form are poorly tolerated, Naklofen can be administered rectally in the form of suppositories at appropriate doses. When combining several dosage forms (in addition to oral administration of the drug), it should be borne in mind that the daily dose of diclofenac should not exceed 150 mg.
Adults with an initial dose of 100-150 mg per day (1 suppository 2-3 times a day), depending on the severity of the disease.
To adolescents aged 15 years and over , one suppository is recommended no more than 2 times a day. The maintenance dose is usually 100 mg per day (1 suppository 2 times a day).
The minimum effective dose should be used as little as possible.

Patients should inform the physician of any chronic illness, metabolic disorder, or sensitivity of the reaction in the history.

When treating the drug Naklofen should carefully monitor patients who have a history of which there are diseases of the upper gastrointestinal tract.

With caution should use the drug with NNC and Crohn's disease because of the possible exacerbation of the disease.

If there are signs of liver damage (skin itching, yellowing of the skin, nausea, vomiting, abdominal pain, darkening of the urine, increasing the level of "liver" transaminases), stop taking the drug and consult a doctor.

With long-term use (more than 2 weeks) of diclofenac, it is necessary to monitor the indicators of liver function (the level of "liver" transaminases).

The use of the drug may adversely affect female fertility and is not recommended for women planning pregnancy.

In infectious diseases, the anti-inflammatory and antipyretic effects of diclofenac sodium can mask the symptoms of these diseases.

In elderly patients, as with other drugs, Naklofen should be used in the lowest effective dose.

Influence on ability to manage motor transport and other complex mechanisms

During the treatment period, it is possible to reduce the speed of mental and motor reactions, so it is necessary to refrain from engaging in potentially dangerous activities that require an increased concentration of attention and speed of psychomotor reactions.


When using suppositories, an overdose is unlikely.

Symptoms: vomiting, nausea, abdominal pain, bleeding from the gastrointestinal tract, diarrhea, headache, dizziness, tinnitus, increased excitability, hyperventilation with increased convulsive readiness, convulsions, with a significant overdose of acute renal failure, hepatotoxic effect.

Treatment: symptomatic therapy aimed at the elimination of high blood pressure (BP), violations of kidney function, seizures, irritation of the gastrointestinal tract, respiratory depression.
Forced diuresis and hemodialysis are ineffective (significant association with proteins and intensive metabolism).

Increases the concentration in the plasma digoxin, methotrexate, lithium and cyclosporine.

Reduces the effect of diuretics, against the background of potassium-sparing diuretics increases the risk of hyperkalemia;
against the background of anticoagulants, antiplatelet agents and trombolytic drugs (alteplase, streptokinase, urokinase), the risk of developing bleeding (bowl - gastrointestinal tract) increases.
Reduces the effect of hypotensive and hypnotic drugs.
Increases the likelihood of side effects of other NSAIDs and GCS (bleeding from the gastrointestinal tract), toxicity of methotrexate and nephrotoxicity of cyclosporine.
Acetylsalicylic acid reduces the concentration of diclofenac in the blood.
Simultaneous use with paracetamol increases the risk of developing nephrotoxic effects of diclofenac.
With simultaneous administration with giglikemicheskimi means can be observed hypo or giperglicemia.
With this combination of funds, it is necessary to monitor the concentration of glucose in the blood.
Cefamandol, cefoperazone, cefotetan, valproic acid and plikamycin increase the incidence of hypoprothrombinemia.

Cyclosporine and gold preparations increase the effect of diclofenac on the synthesis of prostaglandins in the kidneys, which is manifested by increased nephrotoxicity.

Selective serotonin reuptake inhibitors increase the risk of bleeding from the digestive tract.

Simultaneous administration with ethanol, colchicine, corticotropin and preparations of St. John's wort increases the risk of bleeding in the digestive tract.

Medicines that cause photosensitivity, increase the sensitizing effect of diclofenac to ultraviolet radiation.

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

Antibacterial drugs from the quinolone group increase the risk of seizures.
