Citric acid is the most commonly used medicine to prevent stones. From past studies, it has been found that the pH value and citric acid value in urine are closely related to the formation of urinary calculi. In acidic urine, for example, uric acid is very low in solubility, causing uric acid stones: on the contrary, calcium phosphate or magnesium phosphate stones are easy to form in alkaline urine. Because potassium citrate can provide a large amount of citric acid and increase the pH value in urine, it is very effective for the treatment of uric acid stones, calcium citrate stones and renal tubular poisoning caused by calcium stone disease.
Citric acid not only has the above functions, but also causes the increase of potassium ion in the urine and the decrease of ammonia ion. This is due to the fact that potassium citrate not only supplements citric acid, but also adds potassium. But because potassium metabolism in the body is very fast, the blood potassium content has not changed, so little impact on the body. The latter reflects the fact that potassium citrate really does digest urine and reduces the acidity of ammonia ions.
The most common is calcium oxalate stones, oxalic acid and calcium binding in the urine after settling down on the stone formation, this is the most simple solution is to take the citric acid and oxalic acid to competition, activity of citric acid and calcium binding can be precipitated, followed by magnesium or potassium and calcium or magnesium competition. Potassium and oxalic acid did not precipitate or crystallize. As long as the increase in the body of urine citrate and magnesium, potassium, these ingredients can be used to prevent the formation of kidney stones.
Vitamin B6 is the most economical drug, which can promote the combination of citric acid with calcium in urine, reduce the chance of calcium oxalate crystallization, and can be used to prevent calcium oxalate stones. Magnesium Oxide was originally a digestive drug, soft toilet agent, but also can be used to prevent calcium oxalate stones. However, it is particularly noteworthy that magnesium itself is also an ingredient in inflamed stones, so that inflamed urine is not suitable for use.
