Abstract
Cocrystals of a benzamide compound, specifically 3-{[5-(azetidine-1-ylcarbonyl)pyrazin-2-yl]oxy}-5-{[(1S)-1-methyl-2-(methyloxy)ethyl]oxy}-N-(5-methylpyrazin-2-yl)benzamide, therapeutic uses of the benzamide cocrystals and pharmaceutical compositions containing them are disclosed. For purposes of this disclosure and for ease of understanding, “benzamide” or “benzamide compound” as well as “AZD1656” refer to 3-{[5-(azetidine-1-ylcarbonyl)pyrazin-2-yl]oxy}-5-{[(1S)-1-methyl-2-(methyloxy)ethyl]oxy}-N-(5-methylpyrazin-2-yl)benzamide. The benzamide cocrystals of the invention include a 1:1 benzamide fumaric acid (Cocrystal 1), a 1:1 benzamide maleic acid (Cocrystal 2), a 1:1 benzamide malonic acid (Cocrystal 3), a 1:1 benzamide L-tartaric acid hydrate (Cocrystal 4), and a 1:1 benzamide gentisic acid (Cocrystal 5), which includes a 1:1 benzamide gentisic acid form 1 (Cocrystal 5A), a 1:1 benzamide gentisic acid form 2 (Cocrystal 5B), a 1:1 benzamide gentisic acid form 3 (Cocrystal 5C), and a 1:1 benzamide gentisic acid form 4 (Cocrystal 5D).
