Assay—
pH 7.0 Buffer, pH 5.0 Buffer, Mobile phase, Standard preparation, Resolution solution, and Chromatographic system—
Prepare as directed in the Assay under Ceftriaxone Sodium.
Assay preparation—
Allow 1 container of Injection to thaw, and mix. Transfer an accurately measured volume of the Injection, equivalent to about 40 mg of ceftriaxone, to a 200-mL volumetric flask, dilute with Mobile phase to volume, and mix. Use this solution promptly after preparation.
Procedure—
Proceed as directed for Procedure in the Assay under Ceftriaxone Sodium. Calculate the quantity, in mg, of ceftriaxone (C18H18N8O7S3) in each mL of the Injection taken by the formula:
200(C / V)(rU / rS)
in which V is the volume, in mL, of Injection taken; and the other terms are as defined therein.
