Probenecid inhibits the active resorption of uric acid in the kidney, which leads to urinary excretion of uric acid. Explain why this drug would be useful in treating gout.
What will be an ideal response?
Uric acid, a normal waste product of nucleic acid metabolism, is ordinarily excreted in urine without any problem. However, when blood levels of uric acid rise excessively, it may be deposited as needle-shaped urate crystals in the soft tissue of joints. An inflammatory response follows, which leads to gout.
