Novel anhydrous amorphous forms of rosuvastatin calcium, pitavastatin calcium and fluvastatin sodium

摘要

The present invention relates to novel anhydrous amorphous forms of bis[(E)[4-(4-fluorophenyl)isopropyl[methyl(methylsulfonyl)amino]pyrimidinyl](3R,5S)-3,5-dihydroxyhept enoic acid]calcium salt (rosuvastatin calcium), (±)7-(3-(4-fluorophenyl)-1-(1-methylethyl)-1H-indol-2-yl)3,5-dihydroxy heptenoic acid monosodium salt (fluvastatin sodium) and bis[(E)-3,5-dihydroxy-7-[4′-(4″-fluorophenyl)-2′-cyclopropyl-quinolin-3′-hept-6-enoic acid]calcium salt (pitavastatin calcium), to processes for their preparation, to pharmaceutical compositions containing them and to methods of treatment using the same. The rosuvastatin calcium, pitavastatin calcium and fluvastatin sodium obtained are known valuable agents useful in treating hyperlipidemia and hypercholestrolemia.
