Tripelennamine Hydrochloride Injection
» Tripelennamine Hydrochloride Injection is a sterile solution of Tripelennamine Hydrochloride in Water for Injection. It contains not less than 90.0 percent and not more than 110.0 percent of the labeled amount of tripelennamine hydrochloride (C16H21N3·HCl).
Packaging and storage Preserve in tight, single-dose or multiple-dose Containers for Injections, as described under Injections 1. Store at a controlled room temperature, and protect from light.
Labeling Label it to indicate that it is for veterinary use only.

pH 791: between 6.0 and 7.0.
Particulate matter 788: meets the requirements for small-volume injections.
Other requirements It meets the requirements under Injections 1.
Mobile phase Dissolve 4.8 g of monobasic potassium phosphate in 880 mL of water in a 2-liter cylinder. Add 720 mL of methanol and 400 mL of acetonitrile, mix, filter, and degas. Make adjustments if necessary (see System Suitability under Chromatography 621).
Standard preparation Dissolve an accurately weighed quantity of USP Tripelennamine Hydrochloride RS quantitatively in water to obtain a solution having a known concentration of about 0.02 mg per mL. Protect this solution from light.
Assay preparation Transfer an accurately measured volume of Injection, equivalent to about 4 mg of tripelennamine hydrochloride, to a 200-mL volumetric flask, dilute with water to volume, and mix.
Chromatographic system (see Chromatography 621) The liquid chromatograph is equipped with a 254-nm detector, a 3.9-mm × 30-mm guard column that contains packing L1, and a 3.9-mm × 30-cm analytical column that contains packing L1. The flow rate is about 1 mL per minute. Chromatograph the Standard preparation, and record the peak responses as directed for Procedure: the relative standard deviation for replicate injections is not more than 2.0%.
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 tripelennamine peaks. Calculate the quantity, in mg, of tripelennamine hydrochloride (C16H21N3·HCl) in each mL of the Injection taken by the formula:
200(C/V)(rU / rS)in which C is the concentration, in mg per mL, of USP Tripelennamine Hydrochloride RS in the Standard preparation; V is the volume, in mL, of Injection taken to prepare the Assay preparation; and rU and rS are the peak responses obtained from the Assay preparation and the Standard preparation, respectively.
