A benzoic acid derivative with antihyperuricemic property. Probenecid competitively inhibits the active reabsorption of urate at the proximal tubule in the kidney thereby increasing urinary excretion of uric acid and lowering serum urate concentrations. This prevents urate deposition and promotes resolution of existing urate deposits. In addition, probenecid modulates the transport of organic acids and acidic drugs at the proximal and distal renal tubule, thereby increasing the drug serum concentration. or A drug that is used to treat gout and is used together with some antibiotics to make them work better. It is being studied in the treatment of cancer. It belongs to the family of drugs called antibiotic therapy adjuncts.
