Cefotetan Injection
» Cefotetan Injection is a sterile isoosmotic solution of Cefotetan and Sodium Bicarbonate in Water for Injection. It contains one or more buffer substances and a tonicity-adjusting agent. It contains not less than 90.0 percent and not more than 120.0 percent of the labeled amount of cefotetan (C17H17N7O8S4).
Packaging and storage—
Preserve in Containers for Injections as described under Injections 
1
. Maintain in the frozen state.
1. Maintain in the frozen state.
Labeling—
It meets the requirements for Labeling under Injections 1. The label states that it is to be thawed just prior to use, describes the conditions for proper storage of the resultant solution, and directs that the solution is not to be refrozen.

Assay—
Mobile phase, Standard preparation, Resolution solution, and Chromatographic system—
Proceed as directed in the Assay under Cefotetan.
Assay preparation—
Allow the contents of a container of Injection to thaw, and mix the resultant solution. Transfer an accurately measured volume of this solution, equivalent to about 40 mg of cefotetan, to a 200-mL volumetric flask, dilute with Mobile phase to volume, and mix. [note—Use this solution within 10 minutes. ]
Procedure—
Proceed as directed for Procedure in the Assay under Cefotetan. Calculate the quantity, in mg, of cefotetan (C17H17N7O8S4) in each mL of the Injection taken by the formula:
0.2(CP / V)(rU / rS)
in which V is the volume, in mL, of Injection taken to prepare the Assay preparation, and the other terms are as defined therein.
