Drug Interactions

Not to be given IV to patients who are receiving other NSAIDs or anticoagulants including low dose heparin. Renal function may be worsened when used with ciclosporin or triamterene. Altered absorption when given with sucralfate, colestyramine or colestipol. Ophthalmic application of diclofenac may reduce the efficacy of ophthalmic acetylcholine and carbachol. Increased risk of GI ulceration and bleeding when used with corticosteroids, aspirin or anticoagulants. Potentially Fatal: Increases blood levels of digoxin, lithium and methotrexate. Potentiate potassium-sparing diuretics.

Contraindications

Active peptic ulcer; hypersensitivity to diclofenac or other NSAIDs. Treatment of perioperative pain in CABG surgery. 3rd trimester of pregnancy. Topical: Not to be applied onto damaged or nonintact skin.

Mechanism of Action

Diclofenac has potent anti-inflammatory, analgesic and antipyretic actions. It inhibits the enzyme, cyclooxygenase, thus resulting in reduced synthesis of prostaglandin precursors. Absorption: Rapidly absorbed (oral solution, rectal suppository, IM); more slowly (enteric-coated tab). Distribution: Penetrates synovial fluid; enters breast milk (small amounts). Protein-binding: >99%. Metabolism: Extensively hepatic; converted to metabolites. Excretion: About 60% excreted in urine as glucuronide and sulfate conjugates; 35% in bile; 1-2 hr (elimination half-life).

Special Precautions

History of GI ulceration; impaired cardiac, renal or hepatic function; hypertension; lactation. IV admin in patients with moderate or severe renal impairment; hypovolaemia or dehydration; asthma, porphyria. Monitor LFTs in patients on prolonged therapy. May prolong bleeding time; caution when used in patients with coagulation disorders or on anticoagulants. Prolonged therapy may increase risk of anaemia. 1st and 2nd trimester of pregnancy. Elderly, debilitated patients.
