The invention relates to a Shenkang
sodium chloride injection for treating
chronic renal failure, which is prepared from the following raw materials in the
mass ratio: 1500g of
rheum officinale, 1500g of roots of red-rooted
salvia, 4500g of
Astragalus mongholicus, 1500g of red flower and 810g of
sodium chloride. The preparation method comprises the following steps of: after the bulk pharmaceutical chemicals of the
rheum officinale and the roots of the red-rooted
salvia are extracted in the ratio in the formula, carrying out primary
ethanol precipitation, removing tan, carrying out secondary
ethanol precipitation and water
precipitation, carrying out third
ethanol precipitation, and carrying out secondary water precipitation to remove pyrogen and sterilize; then, extracting the red flower and the
Astragalus mongholicus in the ratio in the formula, carrying out primary
ethanol precipitation and water precipitation, and carrying out secondary
ethanol precipitation and water precipitationto remove pyrogen and sterilize by
activated carbon; and finally, combining the two groups of liquid
medicine, carrying out
ultrafiltration, adding
sodium chloride, carrying out fine filtering and sterilizing to obtain the Shenkang
sodium chloride injection. The Shenkang
sodium chloride injection for treating
chronic renal failure has the advantages that the Shenkang
sodium chloride injection canbe directly used to prevent
medicine from being diluted again so as to lower secondary
pollution brought by the process; the Shenkang sodium chloride injection is convenient for doctors and nurses touse, the compliance of a patient using the
medicine is improved; and the Shenkang sodium chloride injection can be used for patients suffering from
