ATC Code

M02AA10 (Ketoprofen)

Active Substance

Ketoprofen (Rec.INN registered by WHO)

Clinical-Pharmacological Group

NSAIDs for external use

Pharmacotherapeutic Group

Drugs for external use for muscle and joint pain; non-steroidal anti-inflammatory drugs for external use

Pharmacological Action

NSAID. It has analgesic, anti-inflammatory, and anti-edematous effects. It inhibits the activity of COX, which leads to the suppression of prostaglandin synthesis.

In addition, Ketoprofen inhibits lipoxygenase, bradykinin synthesis, stabilizes lysosomal membranes, and prevents the release of enzymes involved in the inflammatory process.

Ketoprofen does not have a negative effect on the condition of the articular cartilage.

Pharmacokinetics

Ketoprofen is absorbed very slowly and practically does not accumulate in the body. Bioavailability is 5%.

Ketoprofen penetrates into the subcutaneous tissue, ligaments and muscles, synovial fluid and reaches therapeutic concentrations there. The concentration of the drug in blood plasma is extremely low.

Ketoprofen is metabolized in the liver to form conjugates, which are mainly excreted in the urine. Ketoprofen is characterized by slow excretion in the urine.

Indications

Symptomatic therapy of painful and inflammatory processes of various origins, including: rheumatoid arthritis and periarthritis; ankylosing spondylitis (Bekhterev’s disease); psoriatic arthritis; reactive arthritis (Reiter’s syndrome); osteoarthritis of various locations; tendinitis, bursitis; myalgia; neuralgia; radiculitis; injuries of the musculoskeletal system (including sports), muscle and ligament bruises, sprains, ruptures of ligaments and muscle tendons.

Dosage Regimen

Apply a sufficient amount of gel to the affected area 2 to 3 times daily.

Gently rub the gel into the skin until fully absorbed.

Wash hands thoroughly after each application unless the hands are the treated area.

The maximum duration of self-treatment without consulting a physician is 14 days.

Do not exceed a treated surface area of 10% of the total body surface.

For combination therapy with oral forms, ensure the total daily dose from all formulations does not exceed 200 mg of ketoprofen.

Strictly avoid contact with eyes, mucous membranes, and open or infected wounds.

Do not apply under occlusive dressings.

Protect treated skin from sunlight and UV radiation (including solariums) during treatment and for two weeks after the last application.

Discontinue use and consult a physician if no improvement is observed within the recommended treatment period or if symptoms worsen.

Adverse Reactions

Allergic reactions: very rarely – angioedema, anaphylaxis.

Skin and subcutaneous tissue disorders: infrequently – erythema, itching, burning, eczema, transient mild dermatitis; rarely – urticaria, rash, photosensitivity, bullous dermatitis, purpura, erythema multiforme, lichenoid dermatitis, skin necrosis, Stevens-Johnson syndrome; very rarely – isolated case of severe contact dermatitis (against the background of poor hygiene and insolation), isolated case of severe generalized photodermatitis, toxic epidermal necrolysis.

Respiratory system disorders: very rarely – asthmatic attacks (as a variant of an allergic reaction).

Urinary system disorders: very rarely – deterioration of renal function in patients with chronic renal failure.

Contraindications

Hypersensitivity to ketoprofen; hypersensitivity to salicylates, tiaprofenic acid or other NSAIDs, to fenofibrate, UV blockers, fragrances; violation of the integrity of the skin (eczema, weeping dermatitis, open or infected wound); history of bronchial asthma attacks caused by taking NSAIDs and salicylates; history of photosensitivity reactions; exposure to sunlight, including indirect sunlight and UV radiation in a solarium throughout the entire treatment period and for another 2 weeks after cessation of treatment; third trimester of pregnancy; children under 15 years of age.

With caution

Impaired liver and/or kidney function, erosive and ulcerative lesions of the gastrointestinal tract, blood diseases, bronchial asthma, chronic heart failure.

Use in Pregnancy and Lactation

Use is contraindicated in the third trimester of pregnancy. Use in the first and second trimesters is possible in cases where the expected benefit of therapy for the mother outweighs the potential risk to the fetus.

Use during lactation (breastfeeding) is not recommended.

Use in Hepatic Impairment

Should be used with caution in case of impaired liver function.

Use in Renal Impairment

Should be used with caution in case of impaired renal function.

Pediatric Use

Contraindication: children under 15 years of age.

Geriatric Use

Use with caution in elderly patients.

Special Precautions

Avoid getting this product into the eyes, on the skin around the eyes, and on mucous membranes.

Ketoprofen can be used externally in combination with oral administration. The total daily dose, regardless of the dosage form, should not exceed 200 mg.

To reduce the risk of developing photosensitivity, it is recommended to protect skin areas treated with ketoprofen with clothing from exposure to UV radiation throughout the entire treatment period and for another 2 weeks after stopping the use of the gel.

Do not use with occlusive dressings.

Drug Interactions

Since the concentration of ketoprofen in blood plasma is extremely low, manifestations of interaction symptoms with other drugs (similar to symptoms with systemic use) are possible only with frequent and long-term use.

Concomitant use of other topical agents containing Ketoprofen or other NSAIDs is not recommended.

Concomitant administration of acetylsalicylic acid reduces the degree of binding of ketoprofen to plasma proteins.

Ketoprofen reduces the excretion of methotrexate and contributes to an increase in its toxicity.

Patients taking coumarin-containing anticoagulants are recommended to undergo treatment under medical supervision.

Storage Conditions
