Rarely, aseptic meningitis, potentially severe blood dyscrasias (e.g. agranulocytosis, thrombocytopenia, aplastic anaemia), jaundice.
Ear and labyrinth disorders: Vertigo, tinnitus.
Gastrointestinal disorders: Upper abdominal pain, nausea, vomiting, dyspepsia, diarrhoea, constipation, pancreatitis.
Immune system disorders: Non-specific allergic reactions, angioedema.
Investigations: Abnormal LFT.
Nervous system disorders: Dizziness, headache, drowsiness.
Renal and urinary disorders: Tubulointerstitial nephritis, nephrotic syndrome.
Respiratory, thoracic and mediastinal disorders: Dyspnoea.
Skin and subcutaneous tissue disorders: Rash, pruritus, urticaria, alopecia, photosensitivity reaction.
Potentially Fatal: Gastrointestinal bleeding, ulceration or perforation; asthmatic and anaphylactoid reactions (in patients with aspirin triad), drug reaction with eosinophilia and systemic symptoms (DRESS). Rarely, exfoliative dermatitis, Stevens-Johnson syndrome, toxic epidermal necrolysis, hepatitis.
Patient Counseling Information
This drug may cause dizziness, drowsiness, fatigue and blurred vision, if affected, do not drive or operate machinery.
Monitoring Parameters
Monitor CBC, occult blood loss, LFTs (periodically), renal function (e.g. urine output, BUN, creatinine), electrolytes; response to therapy (e.g. pain, range of motion, grip strength, mobility), inflammation. Observe for weight gain, signs of oedema, bleeding or bruising; signs and symptoms of gastrointestinal effects (e.g. abdominal pain, bleeding, dyspepsia); mental confusion or disorientation. Perform ophthalmic exams periodically (prolonged use); urinalysis and urine culture (if urinary symptoms occur).
Overdosage
Symptoms: Headache, nausea, vomiting, epigastric pain, gastrointestinal bleeding, diarrhoea (rare), disorientation, excitation, drowsiness, dizziness, tinnitus, fainting, convulsion (occasional), coma; in cases of significant poisoning, acute renal failure and liver damage may occur. Management: Symptomatic and supportive treatment. Administer activated charcoal within 1 hour of ingesting a potentially toxic amount. Alternatively, gastric lavage may be performed in adults within 1 hour of ingestion. Ensure good urine output. Administer IV diazepam for frequent or prolonged convulsions. Closely monitor hepatic and renal function. Observe patient for at least 4 hours following ingestion of potentially toxic amount.
Drug Interactions
Increased risk of ulceration or bleeding with oral corticosteroids, anticoagulants (e.g. heparin, warfarin, ticlopidine, clopidogrel, dabigatran, apixaban, rivaroxaban, edoxaban), SSRIs, anti-platelet agents (e.g. aspirin), thrombolytics, nicorandil, pentoxifylline. May increase the plasma concentration of cardiac glycosides, lithium, methotrexate. Increased risk of nephrotoxicity with tacrolimus, ciclosporin, tenofovir disoproxil fumarate. Increased risk of haematological toxicity with zidovudine. May increase the risk of developing convulsion with quinolone antibiotics. May reduce the effects of antihypertensive agents (e.g. ACE inhibitors, angiotensin II receptor antagonists, β-blockers), diuretics, and mifepristone (avoid tiaprofenic acid for at least 8-12 days after mifepristone use). Decreased metabolism and elimination with probenecid. May inhibit the metabolism of sulfonylurea drugs. May decrease the elimination of aminoglycosides.
Potentially Fatal: Increased risk of adverse effect (particularly upper gastrointestinal disorders) with other NSAIDs and high-dose salicylates.
Food Interaction
Delayed absorption with food.
Lab Interference
May result in false-positive aldosterone/renin ratio (ARR).
Action
Description: Tiaprofenic acid is a propionic acid derivate that has antipyretic, analgesic and anti-inflammatory properties. It acts by reversibly inhibiting cyclooxygenase-1 and 2 (COX-1 and 2) enzymes resulting in reduced formation of prostaglandin precursors.
Pharmacokinetics:
Absorption: Rapidly absorbed from the gastrointestinal tract. Delayed absorption with food. Time to peak plasma concentration: 30-90 minutes.
Distribution: Crosses the placenta and enters breast milk. Plasma protein binding: Approx 98%.
Metabolism: Metabolised into inactive metabolites (minimal).
Excretion: Via urine (50% as unchanged drug, <10% as metabolites). Elimination half-life: Approx 2 hours.
