Patent Claims:	1. An injectable solution suitable for parenteral administration comprising: (a) about 30 mg/mL of meloxicam, (b) one or more pharmaceutically acceptable solvents; and (c) a solubilizer, wherein the solubilizer comprises a combination of meglumine and a cyclodextrin derivative, wherein the concentration of meglumine is between 10 mg/mL and 50 mg/mL; wherein the concentration of the cyclodextrin derivative is from about 5 mg/mL to about 250 mg/mL; wherein the solution is a ready-to-use formulation, and wherein the solution is stable and remains clear when stored for 6 months at 40° C./75% RH, and. 2. The solution according to claim 1, wherein the solution has a pH in the range of about 7 to about 10. 3. The solution according to claim 1, wherein the solution has an osmolality between about 100 mOsm and about 2000 mOsm. 4. The solution according to claim 1, wherein the meloxicam and the meglumine are used at a molar ratio of 0.5:1 to 0.5:10. 5. The solution according to claim 1, wherein the meloxicam and the meglumine are used at a molar ratio of 1:0.5 to 10:1. 6. The solution according to claim 1, wherein the concentration of the meglumine is between 15 mg/mL and 30 mg/mL. 7. The solution according to claim 1, wherein the concentration of the meglumine is 20 mg/mL. 8. The solution according to claim 1, wherein the cyclodextrin derivative is hydroxypropyl-β-cyclodextrin (HP-β-CD), and wherein the meloxicam and the HP-β-CD are used in a molar ratio of 0.5:1 to 0.5:10. 9. The solution according to claim 1, wherein the concentration of the cyclodextrin derivative is from about 5 mg/mL to about 220 mg/mL. 10. The solution according to claim 1, comprising about 20 mg/mL of the meglumine, about 150 mg/mL of the cyclodextrin derivative. 11. The solution according to claim 1, further comprising 60 mg/mL of povidone. 12. The solution according to claim 1, wherein the pharmaceutically acceptable solvent is water. 13. The solution according to claim 1, wherein the cyclodextrin derivative is hydroxypropyl-β-cyclodextrin (HP-β-CD). 14. The solution according to claim 1, wherein the solution is prepared by: (i) adding the meglumine with stirring to water, at a temperature of about 50° C. to about 60° C. to form a first solution; (ii) adding the cyclodextrin derivative with stirring to the first solution, at a temperature of about 50° C. to about 60° C. to form a second solution; (iii) adding the meloxicam with stirring to the second solution, at a temperature of about 50° C. to about 60° C. to form the solution according to claim 1.
