Most effective treatment of acute attack of gout is –
**Core Concept**
Gout is a form of inflammatory arthritis caused by elevated levels of uric acid in the blood, leading to the deposition of monosodium urate crystals in the joints. The most effective treatment of an acute gout attack aims to reduce inflammation and alleviate pain.
**Why the Correct Answer is Right**
The most effective treatment for an acute gout attack is the administration of nonsteroidal anti-inflammatory drugs (NSAIDs) such as indomethacin, ibuprofen, or naproxen. These medications work by inhibiting the production of prostaglandins, which are responsible for the inflammatory response in gout. Additionally, NSAIDs also reduce the production of leukotrienes, which contribute to the recruitment of inflammatory cells to the affected joint.
**Why Each Wrong Option is Incorrect**
**Option A:** Colchicine is an alternative treatment for gout, but it is not as effective as NSAIDs in reducing inflammation. Colchicine works by inhibiting microtubule polymerization, which disrupts the movement of inflammatory cells into the affected joint.
**Option B:** Corticosteroids can be used to treat gout, but they are not the first-line treatment for an acute attack. Corticosteroids work by suppressing the immune response and reducing inflammation, but they can have significant side effects, especially with long-term use.
**Option C:** Allopurinol is a xanthine oxidase inhibitor used to prevent the formation of uric acid in the body, but it is not effective in treating an acute gout attack. Allopurinol works by reducing the production of uric acid, but it can take weeks or months to have an effect on the level of uric acid in the blood.
**Clinical Pearl / High-Yield Fact**
It is essential to differentiate between acute gout and pseudogout, as the treatment and prognosis differ between the two conditions. Pseudogout is caused by the deposition of calcium pyrophosphate dihydrate crystals in the joints, and it is often associated with underlying metabolic disorders.
**Correct Answer: A. NSAIDs (e.g., indomethacin, ibuprofen, or naproxen)**
