BRANDS OF KETOPROFEN IN KENYA
KETOPROFEN MODE OF ACTION
Ketoprofen is used for its antipyretic, analgesic, and anti-inflammatory properties by inhibiting cyclooxygenase-1 and -2 (COX-1 and COX-2) enzymes reversibly, which decreases the production of proinflammatory prostaglandin precursors.
Ketoprofen is recommended in the management of rheumatoid arthritis, osteoarthritis, ankylosing spondylitis, acute articular and peri-articular disorders, (bursitis, capsulitis, synovitis, tendinitis), cervical spondylitis, low back pain (strain, lumbago, sciatica, fibrositis), painful musculoskeletal conditions, acute gout, dysmenorrhoea and control of pain and inflammation following orthopedic surgery
DOSAGE AND ADMINISTRATION
Adults: 100 – 200 mg once daily, depending on patient weight and on the severity of symptoms.
The maximum daily dose is 200 mg. The balance of risks and benefits should be carefully considered before commencing treatment with 200 mg daily, and higher doses are not recommended
Elderly: The elderly are at increased risk of the serious consequences of adverse reactions. If an NSAID is considered necessary, the lowest effective dose should be used and for the shortest possible duration. The patient should be monitored regularly for GI bleeding during NSAID therapy.
Pediatric dosage not established.
Undesirable effects may be minimized by using the lowest effective dose for the shortest duration necessary to control symptoms
Ketoprofen is contraindicated in patients who have a history of hypersensitivity reactions such as bronchospasm, asthmatic attacks, rhinitis, angioedema, urticaria, or other allergic-type reactions to ketoprofen, any other ingredients in this medicine, ASA or other NSAIDs. Severe, rarely fatal, anaphylactic reactions have been reported in such patients.
Ketoprofen is contraindicated in patients with hypersensitivity to any of the excipients of the drug.
Ketoprofen is also contraindicated in the third trimester of pregnancy.
Ketoprofen is contraindicated in the following cases:
– Severe heart failure
– active peptic ulcer, or any history of gastrointestinal bleeding, ulceration or perforation
– hemorrhagic diathesis
– severe hepatic insufficiency
– severe renal insufficiency
Increased risk of bleeding
– Vitamin K antagonists (such as warfarin)
– Platelet aggregation inhibitors (such as ticlopidine, clopidogrel)
– Thrombin inhibitors (such as dabigatran)
– Direct factor Xa inhibitors (such as apixaban, rivaroxaban, edoxaban)
If coadministration is unavoidable, the patient should be closely monitored.
Risk of elevation of lithium plasma levels, sometimes reaching toxic levels due to decreased lithium renal excretion. Where necessary, plasma lithium levels should be closely monitored and the lithium dosage levels adjusted during and after NSAIDs therapy.
Other analgesics/NSAIDs (including cyclooxygenase-2 selective inhibitors) and high dose salicylates:
Avoid concomitant use of two or more NSAIDs (including aspirin) as this may increase the risk of adverse effects, particularly gastrointestinal ulceration, and bleeding.
Serious interactions have been recorded after the use of high dose methotrexate with NSAIDs, including ketoprofen, due to decreased elimination of methotrexate. At doses greater than 15 mg/week:
Increased risk of hematologic toxicity of methotrexate, particularly if administered at high doses (> 15 mg/week), possibly related to the displacement of protein-bound methotrexate and to its decreased renal clearance. At doses lower than 15mg/week: During the first weeks of combination treatment, full blood count should be monitored weekly. If there is any alteration of the renal function or if the patient is elderly, monitoring should be done more frequently.
NSAIDs should not be used for 8 – 12 days after mifepristone administration as NSAIDs can reduce the effect of mifepristone.
There is an increased risk of bleeding. More frequent clinical monitoring and monitoring of bleeding time is required.
Antihypertensive agents (beta-blockers, angiotensin-converting enzyme inhibitors, diuretics):
Risk of decreased antihypertensive potency (inhibition of vasodilator prostaglandins by NSAIDs.
Risk of reduced diuretic effect. Patients and particularly dehydrated patients taking diuretics are at a greater risk of developing renal failure secondary to a decrease in renal blood flow caused by prostaglandin inhibition. Such patients should be rehydrated before initiating coadministration therapy and renal function monitored when the treatment is started.
NSAIDs may exacerbate cardiac failure, reduce GFR, and increase plasma glycoside levels.
Increased risk of nephrotoxicity, particularly in elderly subjects.
Increased risk of gastrointestinal ulceration or bleeding.
Animal data indicate that NSAIDs can increase the risk of convulsions associated with quinolone antibiotics. Patients taking NSAIDs and quinolones may have an increased risk of developing convulsions.
Possible increased risk of nephrotoxicity when NSAIDs are given with tacrolimus, particularly in elderly subjects.
Increased risk of bleeding.
Concomitant administration of probenecid may markedly reduce the plasma clearance of ketoprofen.
Anti-platelet agents and Selective serotonin reuptake inhibitors (SSRIs):
Increased risk of gastrointestinal bleeding.
ACE inhibitors and Angiotensin II Antagonists:
In patients with compromised renal function (e.g. dehydrated patients or elderly patients the co-administration of an ACE inhibitor or Angiotensin II antagonist and agents that inhibit cyclooxygenase may result in further deterioration of renal function, including possible acute renal failure.
Increased risk of hematological toxicity when NSAIDs are given

In all cases of major adverse effects, Ketoprofen should be withdrawn at once.
