摘要
A method of preparing a lyophilized powder for injection, including: (1) weighing and mixing aloe powder and Panax pseudo-ginseng powder to yield an active pharmaceutical ingredient, and mixing the active pharmaceutical ingredient and distilled water to yield a mixed aqueous solution; (2) stiffing the mixed aqueous solution to enable the aloe power and the Panax pseudo-ginseng powder to be completely dissolved, and then allowing the mixed aqueous solution to stand; (3) collecting, filtering, and clarifying a supernate obtained in (2); (4) adding hydrochloric acid to a filtrate obtained in (3) to adjust the pH value of the filtrate, heating and sterilizing the filtrate, and then naturally cooling the filtrate, to yield a cooled liquid; (5) adding hydrochloric acid to the cooled liquid to adjust the pH value of the cooled liquid, filtering the cooled liquid and collecting a pharmaceutical solution; and (6) packaging and lyophilizing the pharmaceutical solution.
