Composition and osmolarity are given below: 800 mcg/mL Dopamine Hydrochloride and 5% Dextrose Injection, USP provides 800 mcg/mL Dopamine Hydrochloride, USP and 50 g/L Dextrose Hydrous, USP with an osmolarity of 261 mOsmol/L (calc). 1600 mcg/mL Dopamine Hydrochloride and 5% Dextrose Injection, USP provides 1600 mcg/mL Dopamine Hydrochloride, USP and 50 g/L Dextrose Hydrous, USP with an osmolarity of 269 mOsmol/L (calc). 3200 mcg/mL Dopamine Hydrochloride and 5% Dextrose Injection, USP provides 3200 mcg/mL Dopamine Hydrochloride, USP and 50 g/L Dextrose Hydrous, USP with an osmolarity of 286 mOsmol/L (calc). Dopamine administered intravenously is a myocardial inotropic agent which also may increase mesenteric and renal blood flow plus urinary output. Dopamine hydrochloride is designated chemically as 3,4-dihydroxyphenethylamine hydrochloride, a white crystalline powder freely soluble in water. Dopamine (also referred to as 3-hydroxytyramine) is a naturally occurring biochemical catecholamine precursor of norepinephrine. This VIAFLEX Plus plastic container is fabricated from a specially formulated polyvinyl chloride (PL 2207 Plastic). VIAFLEX containers, including VIAFLEX Plus containers, are made of flexible plastic and are for parenteral use. VIAFLEX Plus on the container indicates the presence of a drug additive in a drug vehicle. The amount of water that can permeate from inside the container into the overwrap is insufficient to affect the solution significantly. Solutions in contact with the plastic container can leach out certain of its chemical components in very small amounts within the expiration period, e.g., di-2-ethylhexyl phthalate (DEHP), up to 5 parts per million. However, the safety of the plastic has been confirmed in tests in animals according to USP biological tests for plastic containers as well as by tissue culture toxicity studies.

Dopamine, a sympathomimetic amine vasopressor, is the naturally occurring immediate precursor of norepinephrine. Dopamine hydrochloride is a white to off-white crystalline powder, which may have a slight odor of hydrochloric acid. It is freely soluble in water and soluble in alcohol. Dopamine HCl is sensitive to alkalies, iron salts, and oxidizing agents. Chemically it is designated as 4-(2-aminoethyl) pyrocatechol hydrochloride, and its molecular formula is C8H11NO2 • HCl. The structural formula is: and the molecular weight is 189.64. Dopamine hydrochloride injection is a clear, practically colorless, sterile, pyrogen-free, aqueous solution of dopamine HCl for intravenous infusion after dilution. Each milliliter of the 40 mg/mL preparation contains 40 mg of dopamine hydrochloride (equivalent to 32.31 mg of dopamine base). Each milliliter of the 80 mg/mL preparation contains 80 mg of dopamine hydrochloride (equivalent to 64.62 mg of dopamine base). Each milliliter of both preparations contains the following: Sodium metabisulfite 9 mg added as an antioxidant; citric acid, anhydrous 10 mg; and sodium citrate, dihydrate 5 mg added as a buffer. May contain additional citric acid and/or sodium citrate for pH adjustment. pH is 3.3 (2.5 to 5.0). Dopamine must be diluted in an appropriate sterile parenteral solution before intravenous administration. ( See Dosage and Administration ) Structure

Dopamine Hydrochloride in 5% Dextrose Injection, USP is a sterile, nonpyrogenic, prediluted solution of dopamine hydrochloride in 5% dextrose injection. It is administered by intravenous infusion. Each 100 mL contains dopamine hydrochloride 80 mg (0.8 mg/mL), 160 mg (1.6 mg/mL) or 320 mg (3.2 mg/mL) and dextrose, hydrous 5 g in water for injection, with sodium metabisulfite added 50 mg as a stabilizer; osmolar concentration, respectively 261, 269, or 286 mOsmol/liter (calc.), pH 3.8 (2.5 to 4.5). May contain hydrochloric acid and/or sodium hydroxide for pH adjustment. Dopamine administered intravenously is a myocardial inotropic agent, which also may increase mesenteric and renal blood flow plus urinary output. Dopamine Hydrochloride is chemically designated 3, 4-dihydroxyphenethylamine hydrochloride (C8H11NO2 • HCl), a white crystalline powder freely soluble in water. It has the following structural formula: Dopamine (also referred to as 3-hydroxytyramine) is a naturally occurring endogenous catecholamine precursor of norepinephrine. Dextrose, USP is chemically designated D-glucose monohydrate (C6H12O6 • H2O), a hexose sugar freely soluble in water. It has the following structural formula: Water for Injection, USP is chemically designated H2O. The flexible plastic container is fabricated from a specially formulated CR3 plastic material. Water can permeate from inside the container into the overwrap but not in amounts sufficient to affect the solution significantly. Solutions in contact with the plastic container may leach out certain chemical components from the plastic in very small amounts; however, biological testing was supportive of the safety of the plastic container materials. Exposure to temperatures above 25°C/77°F during transport and storage will lead to minor losses in moisture content. Higher temperatures lead to greater losses. It is unlikely that these minor losses will lead to clinically significant changes within the expiration period. STRUCTURE 1 STRUCTURE 2
