optionally ethylenediaminetetraacetic acid (EDTA) or disodium salt thereof, as a stabilizing agent;

optionally benzalkonium chloride as a preservative;

optionally one or more antioxidants selected from the group consisting of alpha tocopherol, D-α-tocopherol polyethylene glycol 1000 succinate, ascorbic acid, isoascorbic acid, butylated hydroxyanisole, citric acid monohydrate, potassium metabisulfite, sodium bisulfite, sodium metabisulfite, and sodium sulfite; and

optionally one or more pH adjustment agents selected from the group consisting of adipic acid, ammonium chloride, citric acid, acetic acid, hydrochloric acid, lactic acid, phosphoric acid, propionic acid, sulfuric acid, tartaric acid, sodium hydroxide, sodium citrate, sodium bicarbonate, sodium carbonate, and combinations thereof, to adjust the pH to a final pH between about 2.0 and about 6.0;

5. A single-use, pre-primed nasal spray device comprising a single reservoir containing a nasal spray pharmaceutical formulation, wherein the nasal spray device is a single-dose nasal spray device and one actuation of the single-dose nasal spray device emits about 100 μL of a nasal spray pharmaceutical formulation, wherein the emitted nasal spray pharmaceutical formulation consists of 1 mg of epinephrine, water, dodecyl maltoside, sodium chloride, benzalkonium chloride, disodium salt of ethylenediaminetetraacetic acid (EDTA), sodium metabisulfite, and hydrochloric acid, sodium hydroxide, or both hydrochloric acid and sodium hydroxide as pH adjustment agents to adjust the pH to a final pH between about 3.0 and about 5.0.

6. A single-use, pre-primed nasal spray device comprising a single reservoir containing a nasal spray pharmaceutical formulation, wherein the nasal spray device is a single-dose nasal spray device and one actuation of the single-dose nasal spray device emits about 100 μL of a nasal spray pharmaceutical formulation, wherein the emitted nasal spray pharmaceutical formulation consists of 2 mg of epinephrine water, dodecyl maltoside, sodium chloride, benzalkonium chloride, disodium salt of ethylenediaminetetraacetic acid (EDTA), sodium metabisulfite, and hydrochloric acid, sodium hydroxide, or both hydrochloric acid and sodium hydroxide as pH adjustment agents to adjust the pH to a final pH between about 3.0 and about 5.0.

7. A single-use, pre-primed nasal spray device comprising a single reservoir containing a nasal spray pharmaceutical formulation, wherein the nasal spray pharmaceutical formulation has a volume between about 100 μL and about 140 μL and consists of about 10 mg/mL or 20 mg/mL of epinephrine; water; dodecyl maltoside; sodium chloride; ethylenediaminetetraacetic acid (EDTA) or disodium salt thereof; benzalkonium chloride; sodium metabisulfite; and hydrochloric acid, sodium hydroxide, or both hydrochloric acid and sodium hydroxide, to adjust the pH to a final pH between about 3.0 and about 5.0; and
