The main reason is that long-term high uric acid leads to the deposition of uric acid crystals around the joints, causing a kind of aseptic inflammation of the joints, which will lead to redness, swelling, heat, pain and dysfunction of the joints during the acute attack. The acute attack of gout can be treated with non-steroidal anti-inflammatory drugs, such as etoricoxib tablets, and also with colchicine. However, colchicine has a certain degree of toxicity, and many patients experience severe diarrhea after taking colchicine. If these two types of drugs do not work well, short-term application of glucocorticoid therapy, more commonly known as dexamethasone, can be used under the guidance of a specialist. The acute attack of gout is generally not recommended to be treated with uric acid-lowering drugs.
