摘要:
The present invention provides a crystalline form of rosuvastatin calcium characterized by an X-ray powder diffraction pattern having peaks at about 4.7, 19.4 and 22.3° 2θ±0.2° 2θ. The crystalline form of the invention may be further characterized by a DSC thermogram with an endotherm at about 132° C. and another broad endotherm at about 220° C. to about 240° C., and a TGA thermogram showing a weight loss of about of 3 to about 5 percent up to about 100° C. The invention also provides a pharmaceutical composition comprising the crystalline rosuvastatin calcium, or a pharmaceutically acceptable salt thereof, and at least one pharmaceutically acceptable excipient.

摘要:
The present invention provides novel crystal forms of fexofenadine hydrochloride Forms V, VI and VIII through XV and processes for their preparation and preparation of amorphous form and other crystalline forms of fexofenadine hydrochloride. Forms XIV and XV are solvates of ethyl acetate, while Form IX is a solvate of MTBE or cyclohexane. The forms are useful for administration to humans and animals to alleviate symptoms caused by histamine. The present invention further provides pharmaceutical compositions of the new crystalline forms.
