Preparation method of iron proteinsuccinylate oral solution

The invention relates to a preparation method of an iron proteinsuccinylate oral solution and belongs to the technical field of medicine. The preparation method of the iron proteinsuccinylate oral solution includes the steps that a proper amount of sodium hydroxide, solubilizer and iron protein succinylate are added to purified water with the concentration being 70%, and stirring is conducted so that most of the iron protein succinylate can be dissolved; then the pH value of the solution is controlled to be 7.0-9.5 with a sodium hydroxide solution, stirring is conducted to make the iron protein succinylate be dissolved, then preservative and a flavoring agent are added, water is complemented, and the iron proteinsuccinylate oral solution is prepared and obtained. According to the iron proteinsuccinylate oral solution obtained through the method, the weight of free ions does not exceed 0.1% of the total content, and the iron proteinsuccinylate oral solution is good in clear degree, good in taste, simpler in preparation process and stable in product performance.
