Could a phosphate drug also stop kidney stones?

This study tested whether Tenapanor, a drug already approved for kidney disease, can reduce oxalate absorption from food and lower the amount of oxalate in urine. Oxalate is a key component of many kidney stones. The study involved 18 healthy adults without a history of kidney stones, comparing urine oxalate levels while taking the drug versus a placebo. The goal is to find a new way to prevent kidney stones by blocking oxalate absorption in the gut.
