| description | The invention relates to a method for preparing a decumbent corydalis tuber eye drop and a product. The method comprises the following steps of: dissolving a decumbent corydalis tuber extract, heating, and keeping temperature; heating auxiliary materials for dissolving; and regulating the pH value, regulating permeation pressure, stirring and mixing uniformly, filtering and packaging into separate bags. The method is characterized in that: the pH value of the decumbent corydalis tuber eye drop is regulated to be between 4.6 and 6.5, and the permeation pressure is regulated to be between 0.24 and 0.360 smol/kg; the decumbent corydalis tuber extract is dissolved by using a diluted phosphoric acid solution, wherein the concentration of the diluted phosphoric acid solution is less than or equal to 0.5 mol/L, and a mass ratio of protopine in the decumbent corydalis tuber extract to the mole of phosphoric acid is (0.32-0.43 gram):(0.0036-0.0048 mol); and glycerol is used as a permeation pressure regulator, and the |
