Patent Claims:	1. A method of treating undesired and/or uncontrolled bronchoconstriction comprising the steps of: (a) adding to a nebulizer, from a propellant-free, sterile unit dose in pharmaceutical packaging material about 1 to about 3 mL of a pharmaceutical composition comprising formoterol or a salt thereof at a concentration of from about 0.08 .mu.g/mL to about 43 .mu.g/mL based on formoterol free base, in a pharmacologically suitable solution, wherein the composition further comprises water and a buffer selected from the group consisting of citric acid/phosphate buffer, acetate buffer, citrate buffer and phosphate buffer at a concentration of from about 1 mM to about 50 mM, said composition having a pH of between about 4.5 and about 5.5; and (b) directly administering said composition to a subject in need thereof, without dilution or other modification of said prior to administration. 2. A method of treating undesired and/or uncontrolled bronchoconstriction comprising the steps of: (a) adding to a nebulizer from a propellant-free, sterile unit dose in pharmaceutical packaging material about 1 to about 3 mL of a pharmaceutical composition comprising formoterol or a salt thereof at a concentration of from about 0.08 .mu.g/mL to about 43 .mu.g/mL based on formoterol free base, in a pharmacologically suitable solution, wherein the composition further comprises water and a buffer selected from the group consisting of citric acid/phosphate buffer, acetate buffer, citrate buffer and phosphate buffer at a concentration of from about 1 mM to about 50 mM, said composition having a pH of between about 4.5 and about 5.5 and having an estimated shelf life of greater than 90% after 3 months storage at 25.degree. C. and after 3 years storage at 5.degree. C.; and (b) directly administering said composition to a subject in need thereof, without dilution or other modification of said prior to administration. 3. A method of treating undesired and/or uncontrolled bronchoconstriction comprising the steps of: (a) adding to a nebulizer from a propellant-free, sterile unit dose in pharmaceutical packaging material about 2 mL of a pharmaceutical composition comprising formoterol or a salt thereof at a concentration of from about 0.08 .mu.g/mL to about 43 .mu.g/mL based on formoterol free base, in a pharmacologically suitable solution, wherein the composition farther comprises water and a citrate buffer at a concentration of from about 1 mM to about 20 mM, said composition having a pH of about 5 and having an estimated shelf life of greater than about 94% after 3 months storage at 25.degree. C. and greater than about 96% after 3 months storage at 5.degree. C.; and (b) directly administering said composition to a subject in need thereof, without dilution or other modification of said composition prior to administration. 4. The method of treating undesired and/or uncontrolled bronchoconstriction as in any one of claims 1, 2 and 3 wherein said undesired and/or uncontrolled bronchoconstriction is a symptom or condition of asthma. 5. The method of treating undesired and/or uncontrolled bronchoconstriction as in any one of claims 1, 2 and 3 wherein said undesired and/or uncontrolled bronchoconstriction is a symptom or condition of chronic obstructive pulmonary disease. 6. The method as in any one of claims 1 and 2 wherein said buffer is present at a concentration of between about 1 mM and about 20 mM. 7. The method as in any one of claims 1, 2 and 3 wherein said Pharmaceutical packaging material is selected from the group consisting of blister packs, bottles, tubes, inhalers, pumps, bags, vials, containers and syringes. 8. The method of claim 7 wherein said pharmaceutical packaging material is a vial over wrapped with a laminate. 9. The method as in any one of claims 1 and 2, wherein about 2.0 mL of the composition is nebulized.
