Milrinone Lactate is a member of a 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: CH 3 CHOHCOOH Milrinone is an off-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 slightly soluble in methanol, and very slightly soluble in chloroform and in water. As the lactate salt, it is stable and colorless to pale yellow in solution. Milrinone Lactate 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, 20 and 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/mL and 1.29 mg/mL. These vials require preparation of dilutions prior to administration to patients intravenously. Pre-Mix Flexible Containers : 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 (0.2 mg) milrinone. The nominal concentration of lactic acid is 0.282 mg/mL. Each mL also contains 49.4 mg Dextrose Anhydrous, USP. The pH is adjusted to between 3.2 and 4.0 with lactic acid 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 pre-mix solution. chemical structure
