DEFINITION<\/h2>\n
Insulin Lispro Injection is a sterile, aqueous solution of Insulin Lispro.<\/p>\n
The injection complies with the requirements stated under Injectable Insulin Preparations, with the exception of the test for Insulin in the supernatant, and with the modifications described below.<\/p>\n
Content of insulin lispro, C_{257<\/sub>H_{383<\/sub>N_{65<\/sub>O_{77<\/sub>S_{6<\/sub><\/h3>\n90.0 to 105.0% of the stated amount.<\/p>\n
CHARACTERISTICS<\/h2>\nA clear and colourless solution, free from turbidity and foreign matter.<\/p>\n
IDENTIFICATION<\/h2>\nIn the Assay, the retention time of the principal peak in the chromatogram obtained with solution (1) corresponds to that in the chromatogram obtained with solution (2).<\/p>\n
TESTS<\/h2>\n
Impurities with molecular masses greater than that of insulin lispro<\/h3>\nThe sum of the areas of the peaks in the chromatogram obtained with the test solution with a retention time less than that of the principal peak is not more than 1.5% of the total area of the peaks. Disregard any peak with a retention time greater than that of the peak due to insulin lispro monomer.<\/p>\n
Related proteins<\/h3>\nCarry out the method for liquid chromatography, Appendix III D, using the following solutions.<\/p>\n
(1) Dilute, if necessary, the preparation being examined with 0.01M hydrochloric acid to produce a solution containing 0.35% w\/v of Insulin Lispro. Add 4 \u03bcL of 6M hydrochloric acid per mL of this solution. Maintain the solution at 2\u00b0 to 8\u00b0 and use within 56 hours.<\/p>\n
(2) Prepare a 0.35% w\/v solution of Insulin Lispro in 0.01M hydrochloric acid and add 4 \u03bcL of 6M hydrochloric acid per mL. Allow to stand at room temperature to obtain a solution containing between 0.8% and 11% of A21 desamido insulin lispro.<\/p>\n
CHROMATOGRAPHIC CONDITIONS<\/h4>\n(a) Use a stainless steel column (25 cm x 4.6 mm) packed with octadecylsilyl silica gel for chromatography (5 \u03bcm) with a pore size of 30 nm (Vydac Protein and Peptide C18 is suitable).<\/p>\n
(b) Use gradient elution and the mobile phase described below.<\/p>\n
(c) Use a flow rate of 1 mL per minute.<\/p>\n
(d) Use a column temperature of 40\u00b0.<\/p>\n
(e) Use a detection wavelength of 214 nm.<\/p>\n
(f) Inject 20 \u03bcL for each solution.<\/p>\n
MOBILE PHASE<\/h4>\nMobile phase A Mix 82 volumes of a 2.84% w\/v solution of anhydrous sodium sulfate adjusted to pH 2.3 with orthophosphoric acid and 18 volumes of acetonitrile for chromatography.<\/p>\n
Mobile phase B Mix equal volumes of a 2.84% w\/v solution of anhydrous sodium sulfate, adjusted to pH 2.3 with orthophosphoric acid, and acetonitrile for chromatography.<\/p>\n
Use the following gradient.<\/p>\n\n\n\n\n\n\n\nTime (Minutes)<\/td>\n Mobile phase A (% v\/v)<\/td>\n Mobile phase B (% v\/v)<\/td>\n Comments<\/td>\n<\/tr>\n

The test is not valid unless, in the chromatogram obtained with solution (2), the resolution between the first peak (insulin lispro) and the second peak (A21 desamido insulin lispro) is at least 1.5 and the symmetry factor for the peak due to insulin lispro is less than 2.0.<\/p>\n
LIMITS<\/h4>\nIn the chromatogram obtained with solution (1), the amount of A21 desamido insulin lispro is not more than 1.5%. The total amount of related proteins (excluding A21) is not greater than 4.0%.<\/p>\n
Total zinc<\/h3>\n14 to 35 \u03bcg per 100 units of insulin lispro, determined by atomic absorption spectrometry, Appendix II D, Method I.<\/p>\n
Test solution Shake the preparation gently and dilute a volume containing 200 units of insulin lispro to 25.0 mL with 0.01M hydrochloric acid. Dilute if necessary to a suitable concentration of zinc (for example 0.4 \u03bcg to 1.6 \u03bcg of Zn per mL) with 0.01M hydrochloric acid.<\/p>\n
Reference solutions Use solutions containing a suitable range of concentrations, for example 0.40 \u03bcg, 0.80 \u03bcg, 1.00 \u03bcg, 1.20 \u03bcg and 1.60 \u03bcg of Zn per mL, freshly prepared by diluting zinc standard solution (5 mg per mL Zn) with 0.01M hydrochloric acid.<\/p>\n
