Patent Claims:	1. A method of inhibiting blood clots in a patient in need thereof comprising intravenously administering to the patient a therapeutically effective amount of a ready-to-use liquid composition comprising about 5 mg/mL bivalirudin or a salt thereof, about 0.8 mg/mL sodium acetate, about 100 mg/mL PEG 400, and water and optionally, glacial acetic acid and/or sodium hydroxide, wherein the ready-to-use liquid composition is prepared by a method that comprises mixing bivalirudin or salt thereof, sodium acetate, PEG 400, and water and optionally glacial acetic acid and/or sodium hydroxide to form the ready-to-use liquid composition, the composition is stored at 2-8° C. prior to administration, and the composition has a pH of from greater than 5.0 to 5.7. 2. The method of claim 1, wherein the sodium acetate is sodium acetate trihydrate. 3. The method of claim 1, wherein the composition has a pH of 5.1 to 5.4. 4. The method of claim 3, wherein the percentage of total impurities increases by no more than about 9% from the time of manufacture of the composition up to 12 months of storage at 5° C. as determined by high performance liquid chromatography at a wavelength of 215 nm. 5. The method of claim 1, wherein the bivalirudin is in the form of a trifluoroacetate salt. 6. The method of claim 1, wherein the composition has an osmolality of about 200 to about 600 mOsm/kg. 7. The method of claim 1, wherein the patient has heparin-induced thrombocytopenia (HIT) and/or heparin-induced thrombocytopenia and thrombosis syndrome (HITTS) and is undergoing percutaneous coronary intervention (PCI). 8. The method of claim 1, wherein the composition has not been reconstituted from a lyophilized composition or diluted from a liquid concentrate. 9. A method of inhibiting blood clots in a patient in need thereof comprising intravenously administering to the patient a therapeutically effective amount of a ready-to-use liquid composition comprising about 5 mg/mL bivalirudin or a salt thereof, about 0.8 mg/mL sodium acetate trihydrate, about 100 mg/mL PEG 400, and water, wherein the ready-to-use liquid composition is prepared by a method that comprises mixing bivalirudin or salt thereof, sodium acetate, PEG 400, and water, the composition does not comprise sodium chloride or dextrose, and the composition has a pH of from greater than 5.0 to 5.7. 10. The method of claim 9, wherein the pH of the composition is about 5.25. 11. The method of claim 10, wherein the percentage of total impurities increases by no more than about 9% from the time of manufacture of the composition up to 12 months of storage at 5° C. as determined by high performance liquid chromatography at a wavelength of 215 nm. 12. The method of claim 10, wherein the composition is stored at 2-8° C. prior to administration. 13. The method of claim 10, wherein the bivalirudin is in the form of a trifluoroacetate salt. 14. The method of claim 10, wherein the patient has heparin-induced thrombocytopenia (HIT) and/or heparin-induced thrombocytopenia and thrombosis syndrome (HITTS) and is undergoing percutaneous coronary intervention (PCI). 15. The method of claim 10, wherein the composition has not been reconstituted from a lyophilized composition or diluted from a liquid concentrate. 16. A method of inhibiting blood clots in a patient in need thereof comprising intravenously administering to the patient a therapeutically effective amount of a ready-to-use liquid composition comprising about 5 mg/mL (free base basis) of bivalirudin trifluoroacetate, about 0.8 mg/mL sodium acetate trihydrate, about 100 mg/mL PEG 400, and water, wherein the composition is prepared by mixing the bivalirudin trifluoroacetate, sodium acetate, PEG 400, and water, the composition is free of sodium chloride and dextrose, the composition has a pH of from greater than 5.0 to 5.7, and the percentage of total impurities increases by no more than about 9% from the time of manufacture of the composition up to 12 months of storage at 5° C. as determined by high performance liquid chromatography at a wavelength of 215 nm. 17. The method of claim 16, wherein the pH of the composition is about 5.25. 18. The method of claim 16, wherein the composition is stored at 2-8° C. prior to administration. 19. The method of claim 16, wherein the patient has heparin-induced thrombocytopenia (HIT) and/or heparin-induced thrombocytopenia and thrombosis syndrome (HITTS) and is undergoing percutaneous coronary intervention (PCI). 20. The method of claim 16, wherein the composition has not been reconstituted from a lyophilized composition or diluted from a liquid concentrate. 21. The method of claim 1, wherein the composition has a pH of about 5.25.
