Abstract: The invention provides crystalline forms of 6-[(5S,9R)-9-(4-cyanophenyl)-3-(3,5-dichlorophenyl)-1-methyl-2,4-dioxo-1,3,7-triazaspiro[4.4]non-7-yl]nicotinic acid, its pharmaceutically acceptable salts, or solvates, thereof Further, a process is provided for preparing substituted spiro-hydantoin compounds of the formula I wherein Z is N or CR4b; K and L are independently O or S; Ar is an optionally substituted aryl or heteroaryl; A1, A2, G, and Q are linkers; and R2, R4a, R4c, and R16 are defined in the specification. The process includes the reaction of N-substituted glycine compound and methylene precursor compound with an alkene compound. The substituted spiro-hydantoin compounds of formulae I and II are useful in the treatment of immune and/or inflammatory diseases.

Abstract: The instant invention provides crystalline forms of 1-(3-chlorophenyl)-7-oxo-6-[4-(2-oxo-1 (2H)pyridinyl)phenyl]-4,5,6,7-tetrahydro-1H-pyrazolo[3,4-c]pyridine-3-carboxamide and its solvates thereof; processes for the production of such crystalline forms; pharmaceutical compositions comprising such crystalline forms; and methods of treating thromboembolic disorders with such crystalline forms or such pharmaceutical compositions.

Abstract: A process is provided for making sterile aripiprazole having an average particle size less than 100 microns but preferably greater than 25 microns employing an impinging jet crystallization procedure. The resulting bulk aripiprazole of desired particle size may be used to form a sterile freeze-dried aripiprazole formulation, which upon constitution with water and intramuscular injection releases aripiprazole over a period of at least about one week and up to about eight weeks.
