Abstract

The invention relates to a preparation detection method for substances related to rosuvastatin calcium preparation. The preparation detection method comprises the following steps: preparing (3S,5S)-rosuvastatin calcium diastereoisomer, rosuvastatin-5S-lactone, rosuvastatin-5R-lactone, rosuvastatin-5-oxide, a rosuvastatin photodegradation product 1, a rosuvastatin photodegradation product 2, rosuvastatin photodegradation product 1-lactone and rosuvastatin photodegradation product 2-lactone, which are used as comparison products of the substances related the rosuvastatin calcium preparation; metering a test sample solution, a comparison product solution and a blank solution; and injecting the solutions into a liquid chromatograph respectively. The chromatographic conditions are as follows: a chromatographic column is a C18 chromatographic column; the column temperature is 30-40 DEG C, the flow speed is 0.6-1.0ml/min and the detection wavelength is 210-260nm. The content of the substances related to the rosuvastatin calcium preparation can be detected so as to be good for improving the quality standard of the rosuvastatin calcium preparation.

Description

technical field [0001] The invention relates to a rosuvastatin calcium preparation used for treating hyperlipidemia, in particular to a preparation and detection method for related substances of the rosuvastatin calcium preparation, and belongs to the technical field of medicine. Background technique [0002] Rosuvastatin calcium (rosuvastatin calcium) is a selective HMG-CoA reductase inhibitor, suitable for primary hypercholesterolemia (type Ⅱa, including heterozygous familial hypercholesterolemia) or mixed lipemia Adjunctive therapy in patients with disorder (Type IIb) when diet or exercise regimens are suboptimal. Its chemical name is bis-[E-7-[4-(4-fluorophenyl)-6-isopropyl-2-[methyl(methylsulfonyl)amino]-pyrimidin-5-yl](3R ,5S)-3,5-dihydroxyhept-6-enoic acid] calcium salt (2:1), molecular formula C 44 h 54 CaF 2 N 6 o 12 S 2 , the chemical structure is as follows: [0003] [0004] During the preparation process of rosuvastatin calcium, due to the influence o...
