milrinone lactate in 5% dextrose - Medication Listings

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 compound with a molecular weight of 211.2 and a molecular formula of C 12 H 9 N 3 O. It is freely soluble in dimethyl sulfoxide; very slightly soluble in methanol, practically insoluble in water and in chloroform. As the lactate salt, it is stable and colorless to pale yellow in 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 milrinone lactate equivalent to 200 mcg milrinone. 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 to between 3.2 and 4.0 with lactic acid and/or sodium hydroxide. The flexible plastic container is comprised of polypropylene with a foil overwrap. Water can permeate the plastic into the overwrap, but the amount is insufficient to significantly affect the premixed solution. milrinone-structure
