Description
LURASIDONE HYDROCHLORIDE SOLID DISPERSION
This application claims the benefit of Indian Provisional Patent Application No. 4762/CHE/2012, filed on November 14, 2012, which is incorporated herein by reference.
Filed of the Invention
The present invention provides a novel amorphous solid dispersion of lurasidone hydrochloride in combination with a pharmaceutically acceptable carrier, process for its preparation and pharmaceutical compositions comprising it.
Background of the Invention
Lurasidone hydrochloride is chemically, (3ai?,45,7i?,7a5)-2-[((li?,2i?)-2-{[4-(l ,2- benzisothiazol-3-yl)-piperazin-l-yl]methyl}cyclohexyl)methyl]hexahydro-lH-4,7- methanisoindol-l,3-dione hydrochloride and has the structural formula:
Lurasidone hydrochloride is a typical antipsychotic developed by Dainippon Sumitomo Pharma under the trade name Latuda®.
Lurasidone and its salts were disclosed in US patent No. 5,532,372 ('372 patent). Polymorphism is defined as "the ability of a substance to exist as two or more crystalline phases that have different arrangement and/or conformations of the molecules in the crystal Lattice. Thus, in the strict sense, polymorphs are different crystalline structures of the same pure substance in which the molecules have different arrangements and/or different configurations of the molecules". Different polymorphs may differ in
their physical properties such as melting point, solubility, X-ray diffraction patterns, etc. Although those differences disappear once the compound is dissolved, they can appreciably influence pharmaceutically relevant properties of the solid form, such as handling properties, dissolution rate and stability. Such properties can significantly influence the processing, shelf life, and commercial acceptance of a polymorph. It is therefore important to investigate all solid forms of a drug, including all polymorphic forms, and to determine the stability, dissolution and flow properties of each polymorphic form. Polymorphic forms of a compound can be distinguished in the laboratory by analytical methods such as X-ray diffraction (XRD), Differential Scanning Calorimetry (DSC) and Infrared spectrometry (IR).
Solvent medium and mode of crystallization play very important role in obtaining one polymorphic Form over the other.
Lurasidone and its hydrochloride salt can exist in different polymorphic Forms, which may differ from each other in terms of stability, physical properties, spectral data and methods of preparation.
Process for the preparation of lurasidone hydrochloride was describes in '372 patent. According to the patent, crystalline solid of lurasidone hydrochloride was obtained by dissolving crude lurasidone in acetone at 20 to 30°C and then added a solution of hydrogen chloride in 2-propanol, and isolating. The crystalline lurasidone hydrochloride obtained by the process of the prior art is herein after designated as lurasidone hydrochloride crystalline Form I.
Crystalline Form of lurasidone free base was reported in IP.com Journal (2011), 1 1 (4A), 26.
International patent application publication no. WO 2012/063246 discloses an amorphous Form of lurasidone hydrochloride.
An unpublished application, PCT/IN2012/000548 assigned to Hetero Research Foundation discloses a novel amorphous Form of lurasidone hydrochloride. And also describes lurasidone hydrochloride crystalline Form I.
It was observed that the crystalline Forms and amorphous Form of lurasidone hydrochloride either not reproducible or not stable.
We have also found a novel amorphous solid dispersion of lurasidone hydrochloride in combination with a pharmaceutically acceptable carrier. The amorphous solid dispersion of lurasidone hydrochloride is stable, reproducible and so, the amorphous solid dispersion of lurasidone hydrochloride is suitable for formulating lurasidone hydrochloride. Normally amorphous Forms are hygroscopic. Amorphous solid dispersion of lurasidone hydrochloride is found to be non-hygroscopic.
Thus, an object of the present invention is to provide amorphous solid dispersion of lurasidone hydrochloride in combination with a pharmaceutically acceptable carrier, process for its preparation and pharmaceutical compositions comprising it.
