Intafenac Plus

Adult: One ampoule once (or in severe cases, twice) daily by intramuscular injection.

Renal colic: One ampoule once daily intramuscularly. A second dose may be administered after 30 minutes if necessary.

Children: In Juvenile chronic arthritis, 1-3 mg of Diclofenac Sodium per kg body weight daily in divided doses.

Elderly patients: In elderly or debilitated patients, the lowest effective dosage is recommended, commensurate with age and physical status, or as prescribed by the physician.

Side effects to Diclofenac Sodium and Lidocaine injection are usually mild and transient. However if serious side effects occur the injection should be discontinued. Gastrointestinal discomfort, nausea, diarrhea and occasionally bleeding may occur. In very rare instances, injection site disorder may occur. In isolated cases, abscesses and local necrosis may occur. The adverse effects due to Lidocaine mainly involve the CNS, are usually of short duration, and are dose related. The CNS reactions may be manifested by drowsiness, dizziness, disorientation, confusion, lightheadedness etc.

Diclofenac Sodium is a potent nonsteroidal antiinflammatory drug (NSAID) with marked analgesic and antipyretic properties. It also has some uricosuric effects. The action of Diclofenac appeared to be associated with the inhibition of prostaglandin synthesis. Diclofenac may inhibit synthesis of prostaglandins by inhibiting cyclooxygenase, an enzyme that catalyses the formation of prostaglandin precursors from arachidonic acid. Peak plasma concentration is achieved within half an hour following injection. Lidocaine is the most widely used local anaesthetic drug. It acts more rapidly and is more stable than most other local anaesthetics. It is a very useful surface anaesthetic. Like other local anaesthetics, Lidocaine impairs the generation and conduction of nerve impulses by slowing depolarization. The onset of anaesthesia of Lidocaine Hydrochloride is more rapid and the duration is 1-2 hours.

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