Problems solved by technology

Although the process of platelet adhesion to the subendothelial surface may play an important role in the repair of damaged vessel walls, platelet aggregation thus induced can promote acute thrombotic occlusion of important vascular beds, leading to events with high morbidity such as Myocardial infarction and unstable angina

preparation example Construction

[0089] For the preparation of soft gelatin capsules, the co-crystals of Compound A as defined herein may be mixed with eg vegetable oil or polyethylene glycol. Hard gelatine capsules may contain granules of the compound using the excipients mentioned above for tablets, such as lactose, sucrose, sorbitol, mannitol, starch, cellulose derivatives or gelatin. Liquid or semisolid formulations of the drug may also be filled into hard gelatin capsules.

[0090] Liquid preparations for oral administration may be in the form of syrups or suspensions, eg solutions containing the co-crystals of Compound A as defined herein, with the balance being sugar and a mixture of ethanol, water, glycerol and propylene glycol. Optionally, such liquid preparations may contain coloring agents, flavoring agents, saccharin and carboxymethylcellulose as a thickening agent, or other excipients known to those skilled in the art.

[0091] It is believed that the co-crystal of Compound A as defined herein r...

[0113] Example 1-A: Compound A: Capric Acid Cocrystal Type A

[0114]10.3 mg capric acid in 500 μL methanol was added to 2 mL filtered solution of Compound A in acetone (15 mg / mL) with stirring. The vial was capped and wrapped with parafilm.

[0115] The resulting co-crystalline material gave the peaks listed in Example 2-C (see Figure 19 ) consistent diffraction pattern.
