Pharmacological tests have shown that diluting 2g of potassium citrate granules into 20ml of solution and gavaging mice at 5ml/kg, 10ml/kg, and 20ml/kg respectively can increase the serum potassium content of mice, so it can be used as a potassium supplement. Potassium is the main cation in cells, with a concentration of 150-160mmol/L, while the main cation outside cells is Na+, with a potassium concentration of only 3.5-5.0mmol/L. The body mainly relies on Na+, K+, and ATPase on the cell membrane to maintain the difference in K+ and Na+ concentrations inside and outside the cell. The acid-base balance in the body has an impact on potassium metabolism. For example, when acidosis occurs, H enters the cell. In order to maintain the potential difference between the inside and outside of the cell, K+ is released outside the cell, causing or aggravating hyperkalemia. Metabolic disorders can also affect
