Milrinone Lactate Injection, USP 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 is a white to tan crystalline compound with a molecular weight of 211.2 and an empirical formula of C 12 H 9 N 3 O. It is very slightly soluble in methanol, and very practically insoluble in water, ethanol and chloroform. As the lactate salt, it is stable and colorless to pale yellow in solution. Milrinone Lactate Injection is available as sterile aqueous solutions of the lactate salt of milrinone for injection or infusion intravenously. Sterile, single-dose vials: Single-dose vials of 10 mg per 10 mL, 20 mg per 20 mL or 50 mg per 50 mL contain in each mL milrinone lactate equivalent to 1 mg milrinone and 47 mg Dextrose, Anhydrous, USP, in Water for Injection, USP. The pH is adjusted to between 3.2 and 4.0 with lactic acid or sodium hydroxide. The total concentration of lactic acid can vary between 0.95 mg per mL and 1.29 mg per mL. These vials require preparation of dilutions prior to administration to patients intravenously. Chemical Structure
