Alkaston-B6 Syrup contains Magnesium citrate, Potassium citrate and vitamin B6 (pyridoxine) as main active ingredients. Role of active ingredients: Potassium citrate increases urinary citrate principally by modifying the renal handling of citrate, rather than by increasing the filtered load of citrate. The changes induced by potassium citrate tablets produce a urine that is less conducive to the crystallization of stone-forming salts (calcium oxalate, calcium phosphate and uric acid). Potassium citrate also inhibits the spontaneous nucleation of calcium oxalate and calcium phosphate (brushite). Magnesium citrate inhibits the formation of calcium-oxalate crystals in the urine. Pyridoxine decreases liver production of oxalate and magnesium binds it in the gut to prevent it being reabsorbed and producing calcium oxalate stones in the kidney. Alkaston-B6 Syrup is used for: Optimal maintenance of salt balance, Prevention and/or treatment of kidney stones, To promote optimal kidney health, To prevent calcium oxalate kidney stones. Use under medical supervision.
