The invention provides polymorphic forms of the HMG-CoA reductase inhibitor (3R, 5R)-7-[2-(4-fluorophenyl)-5-isopropyl-3-phenyl-4-[(4-hydroxymethylphenylamino)carbonyl]-pyrrol-1-yl]-3,5-dihydroxy-heptanoic acid, hemi calcium salt. The invention also provides methods for preparing these polymorphic forms, pharmaceutical formulations containing these polymorphic forms and methods of using the polymorphic forms of this HMG-CoA reductase inhibitor. |
