Stonil Oral Solution is a combination of two medicines: Citric Acid and Potassium Citrate. Citric Acid prevents the formation of deposits by binding with salts and also breaks down small deposits that are beginning to form. Potassium Citrate is alkaline in nature and works by neutralizing the acids in the blood and urine, thereby preventing the accumulation of salts in the body. This formulation is primarily used to prevent gout and kidney stones and treat metabolic acidosis in patients with kidney diseases. For more details kindly click on Medicine Salts below:
