When to use diclofenac? Characteristics, indications and contraindications

Diclofenac is a preparation that is available in pharmacies in the form of tablets, gels, injections and patches. This drug has found its greatest use in rheumatology, but it is also used by people who try to combat the pain associated with injuries or, in the case of women, with menstruation. What are the indications for the use of diclofenac?

Diclofenac – drug characteristics

Diclofenac is a non-steroidal anti-inflammatory drug, an aminophenylacetic acid derivative. This preparation was introduced into the medical circulation in 1979 and is now one of the most frequently prescribed and used anti-inflammatory drugs. There are several dozen preparations available in Poland that contain diclofenac. Although diclofenac is an acid, it is pharmacologically in the form of the sodium salt.

Diclofenac – composition and mode of action

The composition of drugs, the main active substance of which is diclofenac, varies and depends on the type of a given preparation. For example, gel preparations, apart from sodium diclofenac, are enriched with auxiliary substances such as: carbomer, isopropyl alcohol, liquid paraffin, lavender oil, lemon oil or purified water. The basis of the mechanism of action of diclofenac is the inhibition of the activity of cycloxygenase, an enzyme that is involved in the synthesis of prostaglandins from lipids in cell membranes. Pro-inflammatory prostaglandins play an important role in the development of inflammatory symptoms. The advantage of diclofenac is that it also inhibits the activity of lipoxygenase, an enzyme responsible for the formation of other pro-inflammatory factors.

Diclofenac – indications

The indication for the use of diclofenac is any inflammation, pain or swelling. Diclofenac is a drug used in the treatment of rheumatoid arthritis, ankylosing spondylitis or gout. Diclofenac can bring relief in the treatment of post-traumatic pain, postoperative pain, neuralgia, menstrual pain and inflammation of the appendages.
