What is Flurbiprofen?

Pharmacological effect
Flurbiprofen is an anti-inflammatory, that is, it has an anti-inflammatory effect. To achieve this effect, flurbiprofen inhibits certain enzymes called cyclooxygenases. These enzymes, in turn, are mainly involved in building up the body's own messenger substances, the prostaglandins.
Prostaglandins increase inflammation and irritate the nerve endings, which send pain signals to the brain. This is where the actual pain perception and processing takes place. If the prostaglandin synthesis from arachidonic acid - it is one of the unsaturated fatty acids - is inhibited by flurbiprofen, the inflammation is also alleviated and the perception of pain is reduced.
Flurbiprofen also affects the temperature regulation in the brain and therefore has a fever lowering effect. Flurbiprofen is usually taken orally; it is almost completely absorbed in the small intestine. The active substance is processed in the liver by the enzyme CYP-2C9 and then excreted renally, i.e. via the kidneys.
This also results in a contraindication for functional disorders of the liver and kidneys. Other contraindications are allergies to non-steroidal anti-inflammatory drugs, stomach ulcers and bleeding. People with Parkinson's disease should also avoid flurbiprofen.

Before the operation, the drops are put into the eye to avoid constriction of the pupils during the operation. A prophylactic dose is usual after the operation to prevent inflammation. In addition, after cataract surgery on the eye, the administration of Ocuflur eye drops prevents water from collecting on the fundus.
