Pharmacology
In general, uricosuric drugs act on the proximal tubules in the kidneys, where they interfere with the absorption of uric acid from the kidney back into the blood. Several uricosurics are known to act in vitro by blocking the function of a protein encoded by the gene SLC22A12, also known as urate transporter 1 or URAT1. URAT1 is the central mediator in the transport of uric acid from the kidney into the blood. In some persons with loss-of-function mutations of URAT1, the uricosurics benzbromarone and losartan had no effect, suggesting these drugs act on URAT1 in vivo. Thus, uricosuric drugs may be candidates for management in a personalized medicine model.
