Non-steroidal anti-inflammatory drug with the expressed antiinflammatory and analgetic effect.




Pharmacological properties:

Pharmacodynamics. Diclofenac of sodium is non-steroidal anti-inflammatory drug, possessing anesthetic, antiinflammatory and febrifugal action.

The main mechanism of its action and side effects connected with it consist in not selective oppression of activity of enzyme of cyclooxygenase 1 and 2 (TsOG1 and TsOG2) that leads to disturbance of metabolism of arachidonic acid, decrease in synthesis of prostaglandins, prostacyclin and thromboxane. Level of various prostaglandins in urine, mucous a stomach and synovial fluid decreases.

It is most effective at pains of inflammatory character. At rheumatic diseases antiinflammatory and analgeziruyushchy effect of diclofenac promotes considerable reduction of expressiveness of pain, morning constraint, a swelling of joints that improves a functional condition of a joint. At injuries, in the postoperative period diclofenac reduces pain and inflammatory hypostasis. As all non-steroidal anti-inflammatory drugs (NPVP), diclofenac has antiagregantny activity. In therapeutic doses sodium diclofenac practically does not exert impact on a bleeding time. At prolonged treatment the analgesic effect of diclofenac of sodium does not decrease.

Pharmacokinetics. Absorption – bystry and full, food slows down absorption speed on 1 – 4 hour and reduces the maximum concentration by 40%. After oral administration of 50 mg the maximum concentration (Cmax) – 1,5 mkg/ml are reached through – 2 - 3 hours. Concentration in plasma is in linear dependence on size of the accepted dose. Change of pharmacokinetics of diclofenac against the background of repeated introduction is not noted. Does not kumulirut at observance of the recommended interval between meals. Bioavailability – 50%. Communication with proteins of plasma – more than 99% (the most part contacts albumine). Gets into synovial fluid; the maximum concentration in synovial fluid is observed at 2-4 o'clock later, than in plasma. An elimination half-life from synovial fluid of 3-6 hours (concentration of active agent in synovial fluid in 4-6 hours after administration of drug is higher, than in plasma, and remains to higher within 12 hours). The interrelation of concentration of drug in synovial fluid with clinical performance of drug is not found out.

Metabolism: 50% of active agent are exposed to metabolism during "the first passing" through a liver. Metabolism results from a repeated or single hydroxylation and a konjyugirovaniye with glucuronic acid. The fermental P450 CYP2C9 system takes part in metabolism of drug. Pharmacological activity of metabolites is lower, than diclofenac.

The system clearance makes 260 ml/min., distribution volume – 550 ml/kg. Plasma elimination half-life – 2 hours. About 70% of the entered dose are removed in the form of pharmacological inactive metabolites by kidneys; less than 1% are removed in not changed look, other part of a dose is removed in the form of metabolites with bile.

At patients with the expressed renal failure (clearance of creatinine less than 10 ml/min.) removal of metabolites with bile increases, at the same time increase in their concentration in blood is not observed.

At patients with chronic hepatitis or the compensated cirrhosis, and also elderly patients pharmacokinetic parameters of diclofenac do not change. Diclofenac gets into breast milk.


Indications to use:

• Inflammatory and degenerative diseases of a musculoskeletal system: the pseudorheumatism, the psoriasis, juvenile chronic arthritis ankylosing a spondylarthritis (Bekhterev's Disease), gouty arthritis, arthritis at a disease of Reuters, rheumatic defeat of soft tissues, an osteoarthrosis of peripheral joints and a backbone including with a radicular syndrome, a tendovaginitis, a periarthritis, a bursitis, a miositis, sinoviit).

• As a part of complex therapy of infectious and inflammatory diseases of an ear, a throat, a nose with the expressed pain syndrome (pharyngitis, tonsillitis, otitis).
• Feverish syndrome.
• Diclofenac is intended for symptomatic therapy and does not influence progressing of a disease.


Route of administration and doses:

Inside, without chewing, in time or after food, washing down with a small amount of water. To adults and teenagers since 15 years (and weighing more than 45 kg) – on 50 mg 2-3 times a day. At achievement of optimum therapeutic effect the dose is gradually reduced and pass to the supporting treatment in a dose 100 mg/days. The maximum daily dose – 150 mg.


Features of use:

Naklofen tablets should be applied with care: coronary heart disease, cerebrovascular diseases, дислипидемия / lipidemia, diabetes mellitus, diseases of peripheral arteries, smoking, clearance of creatinine less than 60 ml/min.; anamnestic data on development of a canker of digestive tract, existence of an infection of Helicobacter pylori, advanced age, long use of non-steroidal anti-inflammatory drugs (NPVP), frequent alcohol intake, heavy somatopathies, the induced porphyria, epilepsy, advanced age, a diverticulitis, general diseases of connecting fabric, considerable decrease in the volume of the circulating blood (VCB) (including after massive surgical intervention), elderly patients (including the receiving diuretics weakened patients and with low body weight), the accompanying therapy by the following drugs: anticoagulants (for example, warfarin), antiagregant (for example, acetylsalicylic acid, klopidogret), peroral glucocorticoids (for example, Prednisolonum), selective serotonin reuptake inhibitors (for example, to tsitalopra, fluoxetine, пароксетин, sertraline). For decrease in risk of development of the undesirable phenomena from digestive tract it is necessary to use a minimal effective dose minimum possible course.

Use of diclofenac for pregnant women is possible only when the expected advantage exceeds potential risk for a fruit. Diclofenac is not recommended to be used during the last trimester of pregnancy. In spite of the fact that diclofenac is found in breast milk in small amounts, its use during breastfeeding is not recommended.

During treatment reduction of speed of mental and motor reactions therefore it is necessary to abstain from occupations potentially dangerous types of activity demanding the increased concentration of attention and speed of psychomotor reactions is possible.

Interaction with other medicines:

Increases concentration in plasma of digoxin, a methotrexate, drugs of lithium and cyclosporine.

Reduces effect of diuretics, against the background of kaliysberegayushchy diuretics the risk of development of a hyperpotassemia amplifies; against the background of anticoagulants, antiagregantny and thrombolytic medicines (an alteplaza, Streptokinasa, an urokinase) the risk of development of bleedings increases (more often than a GIT).

Reduces effect of hypotensive and somnolent medicines.

Increases probability of emergence of side effects of other NPVP and glucocorticosteroids (bleeding from a GIT), toxicity of a methotrexate and nephrotoxicity of cyclosporine.

Acetylsalicylic acid reduces concentration of diclofenac in blood.

Simultaneous use with paracetamol increases risk of development of nefrotoksichny effects of diclofenac.

Reduces effect of hypoglycemic medicines.

Tsefamandol, цефоперазон, цефотетан, valproic acid and пликамицин increase the frequency of development of a prothrombinopenia.

Cyclosporine and drugs of gold increase influence of diclofenac on synthesis of prostaglandins in kidneys that is shown by increase in nephrotoxicity.

Selective serotonin reuptake inhibitors increase risk of development of bleedings from a GIT.

Co-administration with ethanol, colchicine, corticotropin and drugs of a St. John's Wort increases risk of development of bleedings in a GIT.

The medicines causing a photosensitization increase the sensibilizing effect of diclofenac to ultra-violet radiation.

The medicines blocking canalicular secretion increase concentration in diclofenac plasma, thereby, increasing its toxicity.

Antibacterial medicines from group of a hinolon - risk of development of spasms.
