Adenuric tablets contain the active ingredient febuxostat which works to reduce the amount of uric acid in the bloodstream. It is from the group of medicines known as xanthine oxidase inhibitors and is a preventative treatment for gout. Excess amounts of uric acid can build up and cause microscopic crystals to form in the joints and turn into painful gout symptoms.
The body’s uric acid levels are usually managed by the kidneys so that excess urate is excreted in urine and faeces. However, for some people this process fails to work efficiently, leaving a higher amount of urate in the blood and in some cases it can no longer stay soluble. At this stage it can turn into sodium urate crystals which occupy the spaces between joints. The crystals irritate the lining of the joints, called the synovium, making it inflamed and painful to move or touch. The build up of crystals is most commonly found in the extremities, in particular the big toe but also the knees and elbows. Crystals can consequently clump together and form visible bumps under the skin known as tophi which can expand and sometimes cause progressive damage to cartilage and bone.
The NHS estimates that around 1 in 45 people live with gout in the UK. Men over the age of 30 years and women over the age of 60 year are more likely to be diagnosed with gout. However, people of all ages can develop the condition and require treatment.
There are several risk factors which might increase your chances of developing this painful arthritic condition. Health problems such as hypertension, diabetes, kidney disease, high cholesterol and osteoarthritis can lead to gout. In turn some medications used to treat these conditions can also be a contributing factor.
Those who consume a diet high in purines found in food and drinks such as red meat, seafood, offal, beer, spirits and sugary drinks may be more likely to be diagnosed. Gout can also run in families. Your doctor may suggest some lifestyle changes to run alongside your treatment. These changes might include losing weight if you are overweight or altering parts of your diet.
Adenuric tablets prevent symptoms by inhibiting the process carried out by the enzyme xanthine oxidase,which produces uric acid. This in turn reduces the overall amount of urate in the body so that crystals are less likely to form.
Adenuric is not prescribed as an immediate relief for gout symptoms but instead as a long term treatment aiming at preventing gout flare ups.
