Single-dose, ready-to-use injectable formulations

A single-dose, ready-to-use formulation comprising a compound of Formula (I)

• wherein the compound of Formula (I) is present as:
• polymorph Form 1 having an X-ray powder diffraction pattern comprising peaks at ° 2θ values of 6.8±0.2, 12.4±0.2, and 18.5±0.2;
• and
• polymorph Form 9 having X-ray powder diffraction pattern comprising peaks at ° 2θ values of 4.9±0.2, 18.6±0.2, and 21.1±0.2, wherein the compound comprises no more than about 5% by weight of polymorph Form 9, and
• wherein the compound of Formula (I) is prepared by a process comprising:
• (a) providing an aqueous solution comprising water;
• (b) providing a slurry comprising a compound of Formula (I);
• (c) mixing the aqueous solution and the slurry to form a suspension;
• and
• (d) filling a container with the suspension to prepare the single-dose, ready-to-use formulation.
