Sodium Sulfate Injection
» Sodium Sulfate Injection is a sterile, concentrated solution of Sodium Sulfate in Water for Injection, which upon dilution is suitable for parenteral use. It contains not less than 95.0 percent and not more than 105.0 percent of the labeled amount of Na2SO4·10H2O.
Packaging and storage
Preserve in single-dose containers, preferably of Type I glass.
Labeling
Label it to indicate that it is to be diluted before injection to render it isotonic (3.89% of Na2SO4·10H2O).
Pyrogen
When diluted with water for injection to contain 3.89% of Na2SO4·10H2O, it meets the requirements of the Pyrogen Test 151.
pH 791:
between 5.0 and 6.5.
Other requirements
It meets the requirements under Injections 1.
Assay
Transfer an accurately measured volume of Injection, equivalent to about 400 mg of sodium sulfate (Na2SO4·10H2O), to a suitable vessel. Dilute if necessary, to 200 mL, and proceed as directed in the Assay under Sodium Sulfate, beginning with add 1 mL of hydrochloric acid. The weight of the barium sulfate so obtained, multiplied by 1.3804, represents its equivalent of Na2SO4·10H2O.
