Iron-type montmorillonite preparation for the treatment of hyperphosphatemia and iron deficiency anemia and its preparation method

摘要

The present invention relates to an iron-type montmorillonite preparation for treating hyperphosphatemia and iron deficiency anemia and a method for preparing the same. The preparation contains iron-type montmorillonite as an active ingredient, and the iron-type montmorillonite (Fe-montmorillonite) is obtained by immersing or eluting a drug montmorillonite in a water-soluble iron salt solution. The present invention is a drug produced by adding or not adding a pharmaceutical additive to the active ingredient, and when administered via the gastrointestinal tract, the active ingredient binds to a phosphate in the patient's gastrointestinal tract. Then, an insoluble substance is generated and discharged from the body through the digestive tract. This lowers the phosphate in the body of patients with chronic renal failure and achieves the purpose of treating hyperphosphatemia. At the same time, iron-type montmorillonite dissociates excess iron ions that are not bound to phosphate, and is absorbed by the human body to replenish iron ions in the body to treat iron deficiency anemia in patients with chronic renal failure. Fulfill. The above preparation can also be used as a prophylactic agent for hyperphosphatemia and iron deficiency anemia in patients with chronic renal failure. [Selection figure] None
