Patent Claims:	1. A process for preparing a sealed vial or cartridge containing a liquid pharmaceutical formulation, comprising: a. combining human parathyroid hormone and a buffer to maintain a pH from greater than 3 to less than 7, thereby forming a solution, and b. sealing said solution in the vial or cartridge, from which a therapeutically effective dose of parathyroid hormone can be withdrawn for use by a patient. 2. A process for preparing a pharmaceutical composition in the form of a solution, comprising admixing human parathyroid hormone with a buffer to maintain a pH from greater than 3 to less than 7, wherein said solution does not undergo a step of freeze-drying or reconstitution prior to use by a patient. 3. The process of claim 2, wherein said buffer is selected from citrate, tartrate, or acetate. 4. The process of claim 2, said solution further comprising a stabilizer. 5. The process of claim 4, wherein said stabilizer is mannitol. 6.

The process of claim 6, wherein said human parathyroid hormone is PTH(1-84). 8. The process of claim 6, wherein said human parathyroid hormone is PTH(1-34). 9. A sealed vial containing a ready to administer pharmaceutical composition in the form of a solution suitable for administration by a patient, said composition comprising: a) human parathyroid hormone, and b) a buffer to maintain a pH from greater than 3 to less than 7. 10. The vial of claim 9 wherein said buffer is selected from citrate, tartrate, or acetate. 11. The vial of claim 9, said composition further comprising a stabilizer. 12. The vial of claim 11 wherein said stabilizer is mannitol. 13. The vial of claim 9, wherein said human parathyroid hormone is selected from the group consisting of PTH(1-31), PTH(1-34), PTH(1-37), PTH(1-38), PTH(1-41) and PTH(1-84). 14. The vial of claim 13, wherein said human parathyroid hormone is PTH(1-84). 15. The vial of claim 13, wherein said human parathyroid hormone is PTH(1-34). 16. The vial of claim 9 wherein said parathyroid hormone is at a concentration of 25 ug/ml to 1000 ug/ml. 17. A vial containing a stable liquid pharmaceutical formulation suitable for administration by a patient without being reconstituted by said patient prior to use, said formulation comprising: a) human parathyroid hormone (1-34) at a concentration of 250 ug/ml; b) glacial acetic acid at a concentration of 0.41 mg/ml, and sodium acetate (anhydrous) at a concentration of 0.10 mg/ml to maintain a pH from about 3 to 6; c) mannitol at a concentration of 45.4 mg/ml; d) metacresol at a concentration of 3.0 mg/ml; and e) water. 18. A method of treating osteoporosis comprising administration to a patient in need thereof of a formulated solution of human parathyroid hormone and a buffer to maintain a pH from greater than 3 to less than 7, said solution not having been reconstituted prior to administration to a patient. 19. The method according to claim 18 wherein said buffer is selected from citrate, tartrate, or acetate. 20. The method according to claim 18 said solution further comprising a stabilizer. 21. The method according to claim 20 wherein said stabilizer is mannitol. 22. The method according to claim 18 wherein said human parathyroid hormone is selected from the group consisting of PTH(1-31), PTH(1-34), PTH(1-37), PTH(1-38), PTH(1-41) and PTH(1-84). 23. The method according to claim 22 wherein said human parathyroid hormone is PTH(1-84). 24. The method according to claim 22 wherein said human parathyroid hormone is PTH(1-34). 25.
