Decanoy-acetaldehyde sodium frozen-dry powder injecta and preparation method

The invention is a houttuynine sodium bisulfite freeze-dry powder injection solution and its manufacturing method. The character lies in: it uses houttuynine sodium bisulfite with effective dose as the effective ingredients, and it includes bracket solution, solubilizer and oxidization resisting agent. The manufacturing process is: a. the solubilizer is diluted with injection water according to the proportion in prescription, stirs, adds in houttuynine sodium bisulfite, blends with warm water to dissolve them; b. the bracket agent and the oxidization agent are put into the injection water, stirs them until they are dissolved, adds active carbon and boils them for 15 minutes, decarbonizes it with filter film; and adds then into the dissolved liquid in step a, adds in injection water and regulates the pH value between 3.0 and 4.5, the injection water is added to the whole quantity, carries on filter with micro-aperture filter film, samples, content measurement, backup; the product can be produced with current freeze-dry method. The merits of the invention are: quick absorption, quick effect, accurate dose and stable quality.
