Neofenac contains Diclofenac, which is a potent non-steroidal anti-inflammatory drug (NSAID) with marked analgesic and antipyretic properties. It also has some uricosuric effect. The actions of diclofenac appear to be associated principally with the inhibition of prostaglandin synthesis – by inhibiting cyclooxygenase – the enzyme that catalyzes the formation of prostaglandin precursors (endoperoxides) from arachidonic acid. Following oral administration, diclofenac is rapidly absorbed from the gastro-intestinal tract. Peak plasma concentration following ingestion of an enteric coated tablet occurs at about 2 to 3 hours. Diclofenac is 99.7% bound to plasma proteins and plasma half-life for the terminal elimination phase is 1-2 hours. Diclofenac enters the synovial fluid, where maximum concentrations are measured 2-4 hours after the peak plasma values have been obtained. The apparent half-life for elimination from the synovial fluid is 3-6 hours. Diclofenac is extensively metabolized to a range of phenolic compounds. About 60% of the administered dose is excreted via the kidneys in the form of metabolites and less than 1% in unchanged form. The remainder is excreted via the bile in metabolised form. Neofenac Gel contains diclofenac sodium BP 1% as diclofenac diethyl amine. It has been designed for external use. The white creamy non-greasy preparation can easily be rubbed into the skin and its aqueous alcoholic base exerts a soothing and cooling effect on the skin. After local application, the active substance penetrates the skin, accumulates in the underlying tissue and combats both acute and chronic inflammatory reaction. The anti-inflammatory and analgesic properties of Neofenac Gel elicits a clinical response characterized by a marked decrease in inflammatory swelling of traumatic or rheumatic origin. It affords effective relief from tenderness and pain on movement.

Neofenac 50 mg enteric coated tablets: Adults: 75 – 150 mg daily in 2 to 3 divided doses, preferably after food. Dose should be reduced in long term use. Children: 1-3 mg of diclofenac/kg body wt. daily in divided doses. Elderly patients: In elderly or debilitated patients, the lowest effective dosage is recommended, although the pharmacokinetics of diclofenac sodium are not impaired to any clinically relevant extent in elderly patients.

Neofenac Suppository : Suppository should be administered rectally. Adults: 50 mg suppository 2-3 times daily. Maximum daily dose is 150 mg. Children: 12.5 mg suppository 2-3 times daily, or 1-3 mg/kg per day in divided doses.

Neofenac Gel: Gel should be rubbed gently into the skin. Depending on the size of the affected site to be treated 2 – 4 gm. Neofenac Gel should be applied 3 – 4 times daily and rubbed in lightly. After application, the hands should be washed unless they are the site being treated. Use in the elderly: The usual adult dosage may be used. Neofenac Gel may also be given to further treatment with other dosage forms of Neofenac or as prescribed by the physician.


Diclofenac is contra-indicated for those patients who are hypersensitive to diclofenac. 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 inhibiting activity, diclofenac is also contra-indicated.


Renal: Patients with severe hepatic, cardiac or renal insufficiency or the elderly should be kept under close surveillance, since the use of NSAIDs may result in deterioration of renal function. The lowest effective dose should be used and renal function monitored.

Hepatic: If abnormal liver function tests persist or worsen, clinical signs or symptoms consistent with liver disease develop or if other manifestations occur (eosinophilia, rash), diclofenac should be discontinued. All patients who are receiving long term treatment with NSAIDs should be monitored as a precautionary measure (e.g., renal, hepatic function and blood counts).

Neofenac Gel should not be taken by mouth and should not be used under occlusive, airtight dressings. The gel should not be allowed to come in contact with the eyes or mucous membranes.


Side effects to diclofenac are usually mild and transient. However, if serious side effects occur, diclofenac should be discontinued.


Gastrointestinal: Occasional: epigastric pain, other gastro-intestinal disorders (e.g., nausea, vomiting, diarrhoea, abdominal cramps, dyspepsia, flatulence, anorexia).

Rare: gastro-intestinal bleeding, peptic ulcer (with or without bleeding or perforation), bloody diarrhoea. In isolated cases: lower gut disorders (e.g., non-specific haemorrhagic colitis and exacerbations of ulcerative colitis or Crohn’s proctocolitis), pancreatitis, glossitis, constipation, etc.

Neofenac Gel is usually well tolerated. Local irritation, erythema, pruritus or dermatitis may occasionally occur. Although the gel has low systemic absorption, yet the possibility of the systemic side-effects cannot be completely excluded because of use to a relatively large area of skin.


Diclofenac tablets should not be prescribed during pregnancy, unless there are compelling reasons for doing so. The lowest effective dosage should be used. This type of drugs are not recommended during the last trimester of pregnancy. Very small quantities of diclofenac may be detected in breast milk, but no undesirable effects on the infant are to be expected. Since no experience has been acquired with diclofenac gel in pregnancy or lactation, it is not recommended for use in these circumstances.


Neofenac Gel: No drug interaction during treatment with diclofenac gel have been reported.

All other dosage forms may have the following drug interactions :

Lithium and digoxin: Diclofenac may increase plasma concentrations of lithium and digoxin.

Anticoagulants: There are isolated reports of an increased risk of haemorrhage with the combined use of diclofenac and anticoagulant therapy, although clinical investigations do not appear to indicate any influence on anticoagulant effect.

Antidiabetic agents: Clinical studies have shown that diclofenac can be given together with oral antidiabetic agents without influencing their clinical effect.

Cyclosporin: Cases of nephrotoxicity have been reported in patients receiving cyclosporin and diclofenac concomitantly.

Methotrexate: Cases of serious toxicity have been reported when methotrexate and NSAIDs are given within 24 hours of each other.

Quinolone antimicrobials: Convulsions may occur due to an interaction between quinolones and NSAIDs. Therefore, caution should be exercised when considering concomitant therapy of NSAID and quinolones.

Other NSAIDs and steroids: Co-administration of diclofenac with other systemic NSAIDs and steroids may increase the frequency of unwanted effects. With aspirin, the plasma levels of each is lowered, although no clinical significance is known.

Diuretics: Various NSAIDs are liable to inhibit the activity of diuretics. Concomitant treatment with potassium-sparing diuretics may be associated with increased serum potassium levels. So, serum potassium should be monitored.


Symptoms: Lethargy, drowsiness, nausea, vomiting, epigastric pain, GI bleeding, Hypertension, acute renal failure, respiratory depression, anaphylactoid reactions and coma may occur rarely.

Management: Symptomatic and supportive treatment: Immediately empty the stomach by inducing emesis or gastric lavage and administration of activated charcoal may be useful after.
