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 anaesthetic, Lidocaine impairs the generation and conduction of the nerve impulses by slowing depolarization.
*Control of pain and inflammation in orthopaedic, dental and other minor surgery
*Acute trauma and fractures
Low back pain and other acute musculoskeletal disorders such as periarthritis (e.g., frozen shoulder), tendonitis, tenosynovitis, bursitis, sprains, strains, dislocations, fractures
Crystal deposition in the joints ( pyrophosphate arthropathy) and other joint disorder.
Renal colic pain
Juvenile chronic arthritis
Severe migraine attacks
Pain in dysmenorrhea
Intafenac Plus injection also contains Lidocaine Hydrochloride, which acts as a local anaesthetic. Therefore, the possibility of pain at the injection site, which is most likely to occur after intramuscular injection of normal Diclofenac, is minimized if Intafenac Plus injection is used.
Intafenac K is an immediate release tablet of Diclofenac Potassium that works by blocking the action of a substance in the body called cyclo-oxygenase. Cyclo-oxygenase is involved in the production of various chemicals in the body, some of which are known as prostaglandins. Prostaglandins are produced in response to injury or certain diseases and would otherwise go on to cause pain, swelling and inflammation.
Adults: 1- 3 tablet (50 -150 mg) daily in divided doses preferably with food or after food.
Children: 1- 3 mg/kg body weight per day in divided doses.
Intafenac and Intafenac Plus injections are intended for intramuscular injection.
Adults: The dosage is generally one 75 mg ampoule daily. In severe cases (e.g. colic) the daily dose can exceptionally be increased to two ampoules of 75 mg, separated by an interval of a few hours. Alternatively, one ampoule of 75 mg can be combined with other dosage forms (tablets, suppositories) up to a maximum daily dosage of 150 mg.
In migraine attacks, clinical experience is limited to initial use of 1 ampoule of 75 mg administered as soon as possible, followed by suppositories up to 100 mg on the same day if required. The total dosage should not exceed 175 mg on the first day.
Children: In juvenile chronic arthritis, 1-3 mg of Diclofenac sodium/kg body weight daily in divided doses.
Elderly patients: The lowest effective dosage is recommended, commensurate with age and physical status or as prescribed by the physician.
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.
Because of the presence of Lidocaine, it is also contraindicated for those patients who are hypersensitive to local anaesthetics of the amide type, although the incidence is very rare.
Lactation: Very small quantities of Diclofenac may be detected in breast milk, but no undesirable effects on the infant are to be expected.
The safety of Diclofenac eye drops in pregnancy & lactation has not been established and its use therefore is not recommended unless the potential benefit to the mother outweighs the possible risk to the child.
