Vinorelbine Injection
» Vinorelbine Injection is a sterile solution of Vinorelbine Tartrate in Water for Injection. It contains not less than 90.0 percent and not more than 110.0 percent of the labeled amount of vinorelbine (C45H54N4O8).
[Caution—Handle Vinorelbine Injection with great care because it is a potent cytotoxic agent. ]
Packaging and storage— Preserve in single-dose Containers for Injections as described under Injections 1, preferably of Type I glass, protected from light. Store in a refrigerator.

Clarity and color of solution— The solution of Injection (10 mg per mL) is clear. The absorbance of a solution of Injection, determined in a 1-cm cell at 420 nm, with a suitable spectrophotometer, using water as the blank, is not greater than 0.060.
Identification— The retention time and the UV spectrum of the major peak in the chromatogram of the Assay preparation corresponds to that in the chromatogram of the Standard preparation, as obtained in the Assay.
Bacterial endotoxins 85— It contains not more than 3.0 USP Endotoxin units per mg of vinorelbine.
Sterility 71— It meets the requirements when tested as directed for Membrane Filtration under Test for Sterility of the Product to be Examined.
pH 791: between 3.3 and 3.8.

Assay—
Phosphate buffer, Mobile phase, and System suitability solution— Proceed as directed in the Assay under Vinorelbine Tartrate.
Standard preparation— Dissolve an accurately weighed quantity of USP Vinorelbine Tartrate RS in water to obtain a solution having a known concentration of about 0.14 mg per mL.
Assay preparation— Transfer an accurately measured volume of Injection, equivalent to about 10 mg of vinorelbine, to a 100-mL volumetric flask, dilute with water to volume, and mix.
Chromatographic system (see Chromatography 621)— The liquid chromatograph is equipped with a diode-array detector and a 3.9-mm × 15-cm column that contains packing L1. The column temperature is maintained at 40. The flow rate is about 1.0 mL per minute. Chromatograph the System suitability solution, and record the peak responses as directed for Procedure: the relative retention, r, between vinorelbine tartrate and vinorelbine related compound A is not less than 1.1. [note—For peak identification purposes, the relative retention times are about 0.8 for the photodegradation product, 1.0 for vinorelbine, and 1.2 for vinorelbine related compound A. ]
Procedure— Separately inject equal volumes (about 20 µL) of the Standard preparation and the Assay preparation into the chromatograph, record the chromatograms, and measure the responses for the vinorelbine peaks, using a diode-array detector. Calculate the quantity, in mg, of vinorelbine (C45H54N4O8) in each mL of the Injection taken by the formula:
(778.93/1079.11)C(L/D)(rU / rS)
in which 778.93 and 1079.11 are the molecular weights of vinorelbine and vinorelbine tartrate, respectively; C is the concentration, in mg per mL, of USP Vinorelbine Tartrate RS in the Standard preparation; L is the labeled quantity, in mg, of vinorelbine in each mL of Injection taken; D is the concentration, in mg per mL, of vinorelbine in the Assay preparation; and rU and rS are the peak responses at 267 nm obtained from the Assay preparation and the Standard preparation, respectively.
