The correct name for ketoacetic acid tablets is compound alpha-ketoacetic acid tablets, which prevent and treat damage caused by dysregulation of protein metabolism due to chronic renal insufficiency, and are usually used in patients with glomerular filtration rates of <25 ml/min, and must be used in conjunction with a low-protein diet. The drug provides essential amino acids and reduces amino nitrogen intake, which reduces urea synthesis and accumulation of uremic toxic products, and improves renal osteodystrophy secondary to hyperparathyroidism and renal hyperphosphatemia. Compound alpha-keto acid tablets should be taken with a meal to allow for adequate absorption and conversion to the appropriate amino acids. Hypercalcemia may occur while taking this drug, so blood calcium levels should be monitored regularly and adequate caloric intake should be ensured. It is contraindicated in patients with hypercalcemia and disorders of amino acid metabolism. As the drug contains phenylalanine, patients with hereditary phenylketonuria should avoid using it. If you need to use the drug patients, please under the guidance of a doctor to strictly follow the instructions of the doctor to take medication, do not self-medication.
