Bacterial endotoxins 85 It contains not more than 0.33 USP Endotoxin Unit per mg of vancomycin hydrochloride.
Sterility 71 It meets the requirements when tested as directed for Membrane Filtration under Test for Sterility of the Product to be Examined, except to dissolve the specimen in water, instead of in Fluid A.
Particulate matter 788: meets the requirements under small-volume injections.
Heavy metals, Method II 231: not more than 0.003%.
Other requirements It responds to the Identification test and meets the requirements of the tests for pH, Water, and Chromatographic purity under Vancomycin Hydrochloride. It meets also the requirements for Uniformity of Dosage Units 905 and for Labeling under Injections 1.
Assay preparation 1 Dissolve a suitable quantity of Sterile Vancomycin Hydrochloride, accurately weighed, in water, and dilute quantitatively with water to obtain a solution containing about 1 mg of vancomycin per mL.
Assay preparation 2 (where it is packaged for dispensing)Dissolve the contents of 1 container of Sterile Vancomycin Hydrochloride in water, and dilute quantitatively with water to obtain a solution having a concentration of about 1 mg of vancomycin per mL.
Assay preparation 3 (where the label states the quantity of vancomycin in a given volume of constituted solution)Constitute 1 container of Sterile Vancomycin Hydrochloride in a volume of water, accurately measured, corresponding to the volume of solvent specified in the labeling. Dilute an accurately measured volume of the constituted solution quantitatively with water to obtain a solution having a concentration of about 1 mg of vancomycin per mL.
Procedure Proceed as directed under AntibioticsMicrobial Assays 81, using an accurately measured volume of the appropriate Assay preparation diluted quantitatively with Buffer No. 4 to yield a Test Dilution having a concentration assumed to be equal to the median dose level of the Standard.
