Milrinone lactate is a member of a new class of bipyridine inotropic/vasodilator agents with phosphodiesterase inhibitor activity, distinct from digitalis glycosides or catecholamines. Milrinone lactate is designated chemically as 1,6-dihydro-2-methyl-6-oxo-[3,4’-bipyridine]-5-carbonitrile lactate and has the following structure: Milrinone, USP is a white to tan crystalline powder with a molecular weight of 211.2 and a molecular formula of C 12 H 9 N 3 O. It is slightly soluble in methanol, and very slightly soluble in chloroform and in water. As the lactate salt, it is stable and clear, colorless to pale yellow solution. Milrinone is available as sterile aqueous solutions of the lactate salt of milrinone for infusion intravenously. The flexible containers provide two ready-to-use dilutions of milrinone in volumes of 100 mL and 200 mL of 5% Dextrose Injection. Each mL contains 285 mcg milrinone lactate equivalent to 200 mcg milrinone USP. The nominal concentration of lactic acid is 0.282 mg/mL. Each mL also contains 54.3 mg Dextrose Hydrous, USP. The pH is adjusted with lactic acid and/or sodium hydroxide pH 3.5 (3.2 to 4.0). The flexible plastic container is made up of multilayer polypropylene with a foil overwrap. Solutions in contact with the plastic container 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. The flexible container has a foil overwrap. Water can permeate the plastic into the overwrap, but the amount is insufficient to significantly affect the premixed solution.
