DEFINITION<\/h2>\n
Tablets containing Ticagrelor (3087), for human use.<\/span><\/p>\n

Content<\/h3>\n
95.0 per cent to 105.0 per cent of the content of ticagrelor (C_{23<\/sub>H_{28<\/sub>F_{2<\/sub>N_{6<\/sub>O_{4<\/sub>S) stated on the label.<\/p>\n}}}}}
IDENTIFICATION<\/h2>\n
A. Record the UV spectrum of the principal peak in the chromatograms obtained with the solutions used in the assay, with a diode array detector in the range of 210-400 nm.<\/p>\n
Results: The UV spectrum of the principal peak in the chromatogram obtained with the test solution is similar to the UV spectrum of the principal peak in the chromatogram obtained with reference solution (a).<\/p>\n
B. Examine the chromatograms obtained in the assay.<\/p>\n
Results: The principal peak in the chromatogram obtained with the test solution is similar in retention time and size to the principal peak in the chromatogram obtained with reference solution (a).<\/p>\n

Solvent mixture acetonitrile R, water R (35:65 V\/V). Buffer solution 156 g\/L solution of sodium dihydrogen phosphate R adjusted to pH 3.0 with phosphoric acid R.<\/p>\n
Test solution: To an appropriate number of tablets add about half of a suitable volume of the solvent mixture. Shake using a mechanical shaker until the tablets have disintegrated completely and dilute to volume with the solvent mixture to obtain a concentration of ticagrelor of 0.45 mg\/mL. If necessary, more than 1 dilution with the solvent mixture may be performed to obtain this concentration.<\/p>\n
Reference solution (a): Dissolve 45.0 mg of ticagrelor CRS in the solvent mixture and dilute to 100.0 mL with the solvent mixture.<\/p>\n
Reference solution (b): Dilute 1.0 mL of the test solution to 100.0 mL with the solvent mixture. Dilute 2.0 mL of this solution to 10.0 mL with the solvent mixture. Reference solution (c) Dissolve 4.5 mg of ticagrelor for system suitability CRS (containing impurities A, B and D) in the solvent mixture and dilute to 10 mL with the solvent mixture.<\/p>\n
