Contraindication ::

In patients with active or suspected peptic ulcer or gastrointestinal bleeding, or for those patients in whom attacks of asthma, urticaria or acute rhinitis are precipitated by aspirin or other NSAIDs possessing prostaglandin synthetase inhibitinig activity, it is also contraindicated. Lidocaine is contraindicated in patients with a known history of hypersensitivity to local anesthetics of the amide-type.

Drug Precautions ::

History of gastrointestinal ulceration, haematemesis or melaena, ulcerative colitis, Asthma or history of asthma, Crohn’s disease, bleeding diathesis or haematological abnormalities. Patients with severe hepatic, cardiac or renal insufficiency or the elderly people, Current or previous high blood pressure ( hypertension) should be kept under close surveillance. All patients who are receiving long-term treatment with NSAID agents should be monitored as a precautionary measure (e.g., renal, hepatic function and blood counts).If abnormal liver function tests persist or worsen, clinical signs and symptoms consistent with liver disease develop or if other manifestations occur, Diclofenac sodium should be discontinued.

Drug Side Effects ::

Side-effects of Diclofenac is usually mild and transient. It is generally well tolerated. At the starting of the treatment, however, patients may sometimes complain of gastrointestinal discomfort, epigastria pain, eructation, nausea and Diarrhoea, headache and bleeding sometime may occur. Occasionally skin rash, peripheral oedema and abnormalities of serum transaminase have been reported.Very rarely reported side effects include activation of peptic ulcer, haematemesis or melena, blood dyscrasia (extensive usage). There have been isolated reports of anaphylactoid reactions. The adverse effects due to Lidocaine mainly involve the CNS, are usually of short duration, and are dose related. The CNS reaction may be manifested by drowsiness, dizziness, disorientation, confusion, lightheadness, etc. Incase of eye drops ocular burning sensation or allergic reaction may occur in 5-10% patients.

Drug Mode of Action ::  

Diclofenac, a phenylacetic acid derivative is a prototypical NSAID. It has potent anti-inflammatory, analgesic and antipyretic actions. It reversibly inhibits the enzyme, cyclooxygenase, thus resulting in reduced synthesis of prostaglandin precursors. Lidocaine is an amide type local anaesth. It stabilises the neuronal membrane and inhibits Na ion movements, which are necessary for conduction of impulses. In the heart, lidocaine reduces depolarisation of the ventricles during diastole and automaticity in the His-Purkinje system. Duration of action potential and effective refractory period are also reduced.

Drug Interactions ::

May increase serum levels of methotrexate. Concomitant use w/ other NSAIDs or anticoagulants (e.g. warfarin) is associated w/ higher risk of GI bleeding. Increased risk of nephrotoxicity w/ ciclosporin or triamterene. May increase the risk of developing corneal complications in patients w/ significant pre-existing corneal inflammation when use concomitantly w/ ophth preparation containing corticosteroids. Colestyramine and colestipol reduce the bioavailability of diclofenac. Decreased plasma concentration when administered after sucralfate. Ophth application of diclofenac may reduce the efficacy of ophth acetylcholine and carbachol. May increase serum levels of lithium and digoxin. May increase serum levels w/ cimetidine and propranolol. Increased risk of cardiac depression w/ ?-blockers and other antiarrhythmics. Additive cardiac effects w/ IV phenytoin. Hypokalaemia caused by acetazolamide, loop diuretics and thiazides may antagonise effect of lidocaine. Dose requirements may be increased w/ long-term use of phenytoin and other enzyme-inducers.
