A method for rapidly preparing a phosphorous binder and a medicament contained thereof are provided. The method includes dissolving FeCl3 and Mg(OH)2 in an acid solution with pH 0.2~1 to form a clear mixture. Than the pH value of the clear mixture is adjusted to pH 9~10 to form a cloudy solution with Mg-Fe-Cl LDH powder suspended. The medicament containing Mg-Fe-Cl LDH powder as an active ingredient is used for treating phosphorus metabolism disorder.一種快速製備磷結合劑的方法及含磷結合劑的醫藥組合物,包含以三氯化鐵(FeCl3)與氫氧化鎂(Mg(OH)2)溶於酸溶液中(pH=0.2~1)後,再將酸鹼值調至鹼性(pH=9~10),即形成中間層陰離子為氯的鎂-鐵層狀雙層氫氧化物(Mg-Fe-Cl LDH)粉末的溶液。此鎂-鐵層狀雙層氫氧化物之粉末可應用於製備具有治療磷代謝障礙用途的醫藥組合物。110...步驟120...步驟130...步驟
