Patent Claims:	1. A pharmaceutical composition in unit dosage form in a vial or ampoule having excellent storage stability over a period of 2 years and suitable for parenteral administration having anti-inflammatory, anti-pyretic and analgesic properties, which consists of a therapeutically effective amount of the d,l or l-lysine salt of R,S or S- ibuprofen as active ingredient dissolved in sterile water to form a solution in the absence of an inert atmosphere and substantially free of any excipient, organic solvent, buffer, acid, base, salt other than the active ingredient and capable of storage in the absence of an inert atmosphere. 2. A method of treating pain or inflammation or of reducing fever in a mammalian subject which comprises the step of parenterally administering to said mammalian subject, a therapeutically effective amount of the pharmaceutical composition defined in claim 1. 3. The method of treating pain or inflammation or of reducing fever defined in claim 2 wherein the mammalian subject is a human patient. 4. The method of treating pain or inflammation or of reducing fever defined in claim 3 wherein the human patient is a premature neonate. 5. The method of treating pain or inflammation or of reducing fever defined in claim 3 wherein the human patient suffers from kidney disease. 6. The method of treating pain or inflammation or of reducing fever defined in claim 2 wherein the pharmaceutical composition is administered by injection. 7. The method of treating pain or inflammation or of reducing fever defined in claim 6 wherein the injection is intravenous, intramuscular or subcutaneous injection. 8. A method of treating patent ductus arterious or intraventricular hemorrhage in a prematurely born neonate which comprises the step of parenterally administering to said prematurely born neonate, a therapeutically effective amount of the pharmaceutical composition defined in claim 1. 9. A method of preparing the pharmaceutical composition defined in claim 1 which comprises the steps of dissolving the d,l- or l-lysine salt of R,S or S-ibuprofen in sterile water to form a solution in the absence of an inert atmosphere and substantially free of any excipient, organic solvent, buffer, acid, base, salt other than the active ingredient and capable of storage in the absence of an inert atmosphere, adding the solution to a vial or ampoule, and closing the vial or ampoule. 10. A method of preparing the pharmaceutical composition defined in claim which comprises the step of dissolving d,l- or l-lysine and R,S or S-ibuprofen in sterile water to form in situ a solution of the d,l- or l-lysine salt of R,S or S-ibuprofen in the absence of an inert atmosphere and substantially free of any excipient, organic solvent, buffer, acid, base, salt other than the active ingredient and capable of storage in the absence of an inert atmosphere, adding the solution to a vial or ampoule, and closing the vial or ampoule. 11. A pharmaceutical composition in unit dosage form in a vial or ampoule shaving excellent storage stability over a period of 2 years and suitable for parenteral administration having anti-inflammatory, anti-pyretic and analgesic properties, which consists of a therapeutically effective amount of the d,l or l-lysine salt of R,S or S- ibuprofen as active ingredient dissolved in sterile water to form a solution in the absence of an inert atmosphere and absolutely free of any excipient, organic solvent, buffer, acid, base, salt other than the active ingredient and capable of storage in the absence of an inert atmosphere. 12. A method of treating pain or inflammation or of reducing fever in a mammalian subject which comprises the step of parenterally administering to said mammalian subject, a therapeutically effective amount of the pharmaceutical composition defined in claim 11. 13. The method of treating pain or inflammation or of reducing fever defined in claim 12 wherein the mammalian subject is a human patient. 14. The method of treating pain or inflammation or of reducing fever defined in claim 13 wherein the human patient is a premature neonate. 15. The method of treating pain or inflammation or of reducing fever defined in claim 13 wherein the human patient suffers from kidney disease. 16. The method of treating pain or inflammation or of reducing fever defined in claim 12 wherein the pharmaceutical composition is administered by injection. 17. The method of treating pain or inflammation or of reducing fever defined in claim 16 wherein the injection is intravenous, intramuscular or subcutaneous injection. 18. A method of treating patent ductus arterious or intraventricular hemorrhage in a prematurely born neonate which comprises the step of parenterally administering to said prematurely born neonate, a therapeutically effective amount of the pharmaceutical composition defined in claim 11. 19. A method of preparing the pharmaceutical composition defined in claim 11 which comprises the steps of dissolving the d,l- or l-lysine salt of R,S or S-ibuprofen in sterile water to form a solution in the absence of an inert atmosphere and absolutely free of any excipient, organic solvent, buffer, acid, base, salt other than the active ingredient and capable of storage in the absence of an inert atmosphere, adding the solution to a vial or ampoule, and closing the vial or ampoule. 20. A method of preparing the pharmaceutical composition defined in claim 11 which comprises the steps of dissolving d,l- or l-lysine and R,S or S-ibuprofen in sterile water to form in situ a solution of the d,l- or l-lysine salt of R,S or S-ibuprofen in the absence of an inert atmosphere and absolutely free of any excipient, organic solvent, buffer, acid, base, salt other than the active ingredient and capable of storage in the absence of an inert atmosphere, adding the solution to a vial or ampoule, and closing the vial or ampoule.
