The invention is directed to a series of novel crystalline olanzapine forms, in particular hydrated and solvated crystalline forms of olanzapine, methods of use in pharmaceutical compositions, and method of treating psychiatric disorders using the crystalline forms. One series of the crystalline forms are hydrates, i.e. water containing crystals, wherein water may be present in a ratio of about 2:1.5 to a ratio of about 1:3 olanzapine:water, while another includes solvates such as an isobutanol solvate. The olanzapine crystalline forms include Forms H, G, Y, X, K, S, Q, Z, and J.
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 anhydrous, but can be crystallized as 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.
