Pharmacological properties

Pharmacodynamics. Aceclofenac is a derivative of phenylacetic acid, inhibits cyclooxygenase I and II types. Has anti-inflammatory, analgesic and antipyretic activity. Inhibits the synthesis of prostaglandins and, thus, affect the pathogenesis of inflammation, pain and fever. In rheumatic diseases anti-inflammatory and analgesic effect aceclofenac contributes to a significant decrease in severity of pain, morning stiffness, swelling of joints that improves a functional condition of the patient. 

Pharmacokinetics. Aceclofenac rapidly and completely absorbed after ingestion. The time to reach maximum concentration is 1, 25-3 h Penetrates into synovial fluid, where its concentration reaches 57% of the plasma concentration and time to maximum concentrations 2-4 h later than in plasma. The volume of distribution is 25 l. 

Connection with plasma proteins (albuminami) is 99 %. Aceclofenac circulates mostly in unchanged form, the major metabolite is 4'-hydroxyacetophenone. 

The half-life is 4 hours Excreted by the kidneys, mainly in the form hydroxypropionic (about 2/3 of the administered dose).

Use with other drugs

Studies of drug interactions have not been conducted, with the exception of warfarin. 

Aceclofenac metabolized by cytochrome system P450 – CYP2C9, and the data in vitro indicate that aceclofenac can be an inhibitor of this enzyme. Therefore, the potential risk of pharmacokinetic interaction with phenytoin, cimetidine, tolbutamide, phenylbutazone, amiodarone, miconazole and sulfaphenazole. 

As with other NSAIDs there is a risk of pharmacokinetic interaction with drugs, metabolism which takes place in the liver, such as methotrexate and drugs lithium. 

Aceclofenac almost entirely associated with plasma proteins and is, therefore, necessary to consider the possibility of substitution of other drugs strongly bind to plasma proteins. 

Due to the absence of pharmacokinetic interaction studies, the following data are based on information obtained by other NSAIDs: 

You should avoid the following combinations 

NSAIDs inhibit tubular secretion of methotrexate, and this also may be a metabolic interaction leading to a decrease clearance of methotrexate. Therefore, during treatment with high doses of methotrexate, you should always avoid the appointment of NSAIDs. 

Some NSAIDs inhibit the excretion of lithium by the kidneys which leads to elevated concentrations of lithium in serum. Should avoid this combination if it is impossible to conduct frequent monitoring of lithium concentration in blood serum. 

NSAIDs inhibit platelet aggregation and damage the mucous membrane of the gastrointestinal tract, which can increase the activity of anticoagulants and increase the risk of bleeding from the mucosa of the gastrointestinal tract in patients taking anticoagulants. 

You should avoid the combination of aceclofenac with oral anticoagulants of the coumarin group, ticlopidina, with thrombolytic drugs and heparin in the absence of careful control. 

With the following combinations may require dose adjustment and precautions 

It is necessary to consider the possible interaction of NSAIDs and methotrexate, especially in patients with renal insufficiency. When taking both drugs requires monitoring of kidney function. You should take precautions while taking NSAIDs and methotrexate for 24 h as the concentration of methotrexate may increase, leading to increased toxicity of methotrexate. 

It is assumed that the NSAIDs together with cyclosporine or tacrolimus increases the risk of nephrotoxicity due to decreased synthesis of prostacyclin in the kidney. Therefore the simultaneous administration of drugs it is important to monitor renal function. 

Simultaneous treatment with acetylsalicylic acid and other NSAIDs may increase the incidence of adverse reactions, and therefore, caution is required in their joint reception. 

NSAIDs may decrease diuretic effects of furosemide, bumetanide and antihypertensive effect of thiazide diuretics. Concomitant treatment with potassium-sparing diuretics may be associated with an increase of level of potassium in the blood serum, therefore it is necessary to control the content of potassium in the blood. 

NSAIDs can also reduce the effect of some antihypertensive drugs. Angiotensin converting enzyme inhibitors or antagonists of receptors of angiotensin II in combination with NSAIDs can cause kidney failure. The risk of acute renal failure which is usually reversible, may be increased in some patients with impaired renal function, such as elderly patients or patients experiencing a fluid deficit. Therefore, the combination of these drugs with NSAIDs should be used with caution, patients should get enough fluid from food, and should be monitoring of kidney function. 

Was not the effect of aceclofenac on blood pressure when it is taken simultaneously with bendrofluazide, although we can not exclude interaction with other antihypertensive drugs such as beta-blockers. 

Other possible interactions 

It was reported about some cases of hypoglycemia and hyperglycemia. Therefore, aceclofenac is necessary to adjust the dose of drugs that cause hypoglycemia. 

While the use of the drug Aceclofenac: 

  • digoxin, phenytoin or lithium preparations can increase the levels in plasma of these drugs; 
  • diuretics and antihypertensives – can weaken the effect of these medicines; 
  • kalisberegath dioretikov can lead to the development of hyperglycemia and hyperkalemia; 
  • other NSAIDs or corticosteroids increases the risk of side effects from the gastrointestinal tract; 
  • selective inhibitors of serotonin reuptake (citalopram, fluoxetine, paroxetine, sertraline) increases the risk of gastrointestinal bleeding; 
  • cyclosporine – may increase the toxic effects of the latter on the kidneys; 
  • antidiabetic agents – can cause Hypo-and hyperglycemia. When this combination of funds is necessary to control the level of sugar in the blood; 
  • acetylsalicylic acid reduced the concentration of aceclofenac in blood; 
  • antiplatelet agents and anticoagulants – increased bleeding risk (requires regular monitoring of indicators of blood coagulation). 

Special instructions

The severity of adverse reactions can be corrected by lowering the effective single dose necessary to control symptoms. 

Patients with hypertension and/or mild or moderately severe congestive heart failure in history requires appropriate supervision and consultation to the doctor, as was reported fluid retention and edema in the treatment of NSAIDs. 

Data from clinical and epidemiological studies suggests that use of some NSAIDs (particularly at high doses and chronic administration) may increase the risk of arterial thrombosis (for example myocardial infarction or stroke). There is insufficient data to exclude such a risk for aceclofenac. Patients with uncontrolled hypertension, congestive heart failure, coronary heart disease, pathology of peripheral arteries and/or cerebrovascular disease should take aceclofenac only after a careful analysis of the clinical situation. The same caution need to make a decision before long-term treatment of patients with risk of cardiovascular disease (e.g. hypertension, hyperlipidemia, diabetes mellitus and Smoking). 

Aceclofenac must be taken with caution and under close medical supervision to patients suffering from diseases of the gastrointestinal tract, peptic ulcer history, after acute disorders of cerebral circulation, systemic lupus erythematosus, porphyria, disorders of hematopoietic system and blood clotting. 

Patients with Crohn's disease, ulcerative colitis the drug is administered not recommended. 

Caution is necessary in patients with hepatic, renal, or cardiac insufficiency and patients with other diseases likely to develop edema. The NSAIDs this category of patients may lead to deterioration of renal excretion and the occurrence of edema. Patients receiving diuretics, or with increased risk of development of hypovolemia, you must also exercise caution while taking the drug Aceclofenac. 

Caution is necessary in older patients, because they have more frequent side effects. Bleeding from the gastrointestinal tract and/or perforation can be during treatment, especially if the history of a disease of the gastrointestinal tract. In addition, elderly patients are more likely to arise disorders of the liver, kidneys, cardiovascular system. 

All patients receiving long-term treatment with NSAIDs, the necessary monitoring to reduce the risk of adverse reactions (e.g., urinalysis, General and biochemical blood analysis). 

Simultaneous reception of the drug Aceclofenac with any drug, suppresses the activity of cyclooxygenase/prostaglandin, may reduce fertility and is not recommended for women planning pregnancy. Women with history of infertility discontinue use of the drug Aceclofenac. 

Impact on the management of vehicles and mechanisms 

During the period of treatment must be careful when driving and occupation of other potentially hazardous activities, require high concentration and psychomotor speed reactions.
