USP Reference standards 11
USP Hydromorphone Hydrochloride RS.
USP Morphine Sulfate RS.
Identification Place a quantity of finely powdered Tablets, equivalent to about 10 mg of hydromorphone hydrochloride, in a separator, and proceed as directed in the Identification test under Hydromorphone Hydrochloride Injection, beginning with Extract with four 10-mL portions of chloroform.
Medium: water; 500 mL.
Apparatus 2: 50 rpm.
Time: 45 minutes.
Determine the amount of C17H19NO3·HCl dissolved by employing the following method.
Buffer solution, Mobile phase, and System suitability solution Proceed as directed in the Assay.
Test solution Withdraw a 15-mL portion of the solution under test, filter, and discard the first few mL of the filtrate.
Standard solution Dissolve an accurately weighed quantity of USP Hydromorphone Hydrochloride RS in water at a concentration similar to that of the Test solution.
Chromatographic system Proceed as directed in the Assay, except to inject the Standard solution instead of the Standard preparation to obtain the relative standard deviation for replicate injections of not more than 5.0%.
Procedure Proceed as directed in the Assay, except to use an injection volume of about 200 µL.
Tolerances Not less than 75% (Q) of the labeled amount of C17H19NO3·HCl is dissolved in 45 minutes.
Uniformity of dosage units 905: meet the requirements.
Buffer solution Dissolve 10 g of sodium dodecyl sulfate and 20 mL of glacial acetic acid in 1.2 liters of water, and mix.
Mobile phase Prepare a filtered and degassed mixture of Buffer solution and acetonitrile (33:17). Make adjustments if necessary.
System suitability solution Dissolve suitable quantities of USP Morphine Sulfate RS and USP Hydromorphone Hydrochloride RS in water to obtain a solution containing about 30 and 40 µg of each per mL, respectively.
Standard preparation Dissolve an accurately weighed quantity of USP Hydromorphone Hydrochloride RS in water, and dilute quantitatively, and stepwise if necessary, with water to obtain a solution having a known concentration of about 40 µg per mL.
Assay preparation Weigh and finely powder not fewer than 20 Tablets. Transfer a portion of the powder, equivalent to about 4 mg of hydromorphone hydrochloride, to a 100-mL volumetric flask, dissolve in and dilute with water to volume, sonicate if necessary, and mix. Filter a portion of the solution using a glass fiber filter, and discard the first 5 mL.
Chromatographic system (see Chromatography 621) The liquid chromatograph is equipped with a 280-nm detector and a 4.6-mm × 15-cm column that contains packing L1. The flow rate is about 1.5 mL per minute. Chromatograph the System suitability solution, and record the peak responses as directed for Procedure: the resolution, R, between morphine and hydromorphone is not less than 2.0. Chromatograph the Standard preparation, and record the peak responses as directed for Procedure: the tailing factor for the hydromorphone hydrochloride peak is not more than 2.0; and the relative standard deviation for replicate injections is not more than 3.0%.
Procedure Separately inject equal volumes (about 100 µL) of the Standard preparation and the Assay preparation into the chromatograph, record the chromatograms, and measure the responses for the major peaks. Calculate the quantity, in mg, of hydromorphone hydrochloride (C17H19NO3·HCl) in the portion of Tablets taken by the formula:
0.1C(rU / rS)in which C is the concentration, in µg per mL, of USP Hydromorphone Hydrochloride RS in the Standard preparation; and rU and rS are the peak responses obtained from the Assay preparation and the Standard preparation, respectively.
