Drugs to prevent urinary stones

Potassium citrate is currently a drug for preventing stones. Studies have found that the pH and citric acid values in the urine are closely related to the formation of urinary stones. In acidic urine (pH<5.5), the solubility of uric acid is extremely low, which can easily cause uric acid stones; while in alkaline urine (pH>7), calcium phosphate or magnesium phosphate stones are easily formed. 63% of patients with urinary calculi have lower than normal urinary citric acid, and potassium citrate can provide a large amount of citric acid to increase the pH value in urine, so for uric acid stones, hypocalcium citrate stones and renal tubular poisoning The calcium stone disease caused by it has a very significant therapeutic effect. But this will increase the potassium ions in the urine and decrease the ammonia ions. This is because potassium citrate not only supplements citric acid, but also supplements potassium. Since potassium is rapidly metabolized in the body, there is no change in the potassium content in the blood, so it has little effect on the body. The daily total urine output, oxalic acid, phosphate, sodium, magnesium, sulfate, and uric acid of patients with uric acid stones were also not affected by taking potassium citrate.
