✅ Indications & Usage ›

INDICATIONS AND USAGE Milrinone Lactate Injection is indicated for the short-term intravenous treatment of patients with acute decompensated heart failure. Patients receiving milrinone lactate should be observed closely with appropriate electrocardiographic equipment. The facility for immediate treatment of potential cardiac events, which may include life threatening ventricular arrhythmias, must be available. The majority of experience with intravenous milrinone lactate has been in patients receiving digoxin and diuretics.

💉 Dosage & Administration ›

DOSAGE AND ADMINISTRATION Milrinone Lactate Injection, USP should be administered with a loading dose followed by a continuous infusion (maintenance dose) according to the following guidelines: LOADING DOSE 50 mcg/kg: Administer slowly over 10 minutes The table below shows the loading dose in milliliters (mL) of milrinone lactate (1mg/mL) by patient body weight (kg). Loading Dose (mL) Using 1 mg/mL Concentration Patient Body Weight (kg) kg 30 40 50 60 70 80 90 100 110 120 mL 1.5 2 2.5 3 3.5 4 4.5 5 5.5 6 The loading dose may be given undiluted, but diluting to a rounded total volume of 10 or 20 mL (see Maintenance Dose for diluents) may simplify the visualization of the injection rate. MAINTENANCE DOSE Infusion Rate Total Daily Dose (24 Hours) Minimum 0.375 mcg/kg/min 0.59 mg/kg Administer as a continuous intravenous infusion Standard 0.5 mcg/kg/min 0.77 mg/kg Maximum 0.75 mcg/kg/min 1.13 mg/kg Milrinone lactate drawn from vials should be diluted prior to maintenance dose administration. The diluents that may be used are 0.45% Sodium Chloride Injection USP, 0.9% Sodium Chloride Injection USP, or 5% Dextrose Injection USP. The table below shows the volume of diluent in milliliters (mL) that must be used to achieve 200 mcg/mL concentration for infusion, and the resultant total volumes. Desired Infusion Concentration mcg/mL Milrinone Lactate Injection 1 mg/mL (mL) Diluent (mL) Total Volume (mL) 200 10 40 50 200 20 80 100 The infusion rate should be adjusted according to hemodynamic and clinical response. Patients should be closely monitored. In controlled clinical studies, most patients showed an improvement in hemodynamic status as evidenced by increases in cardiac output and reductions in pulmonary capillary wedge pressure. Note: See Dosage Adjustment in Renally Impaired Patients . Dosage may be titrated to the maximum hemodynamic effect and should not exceed 1.13 mg/kg/day. Duration of therapy should depend upon patient responsiveness. The maintenance dose in mL/hr ... [See full FDA label]

🚫 Contraindications ›

CONTRAINDICATIONS Milrinone Lactate Injection is contraindicated in patients who are hypersensitive to it.

⚠️ Warnings ›

WARNINGS Whether given orally or by continuous or intermittent intravenous infusion, milrinone lactate has not been shown to be safe or effective in the longer (greater than 48 hours) treatment of patients with heart failure. In a multicenter trial of 1088 patients with Class III and IV heart failure, long-term oral treatment with milrinone lactate was associated with no improvement in symptoms and an increased risk of hospitalization and death. In this study, patients with Class IV symptoms appeared to be at particular risk of life-threatening cardiovascular reactions. There is no evidence that milrinone lactate given by long-term continuous or intermittent infusion does not carry a similar risk. The use of milrinone lactate both intravenously and orally has been associated with increased frequency of ventricular arrhythmias, including nonsustained ventricular tachycardia. Long-term oral use has been associated with an increased risk of sudden death. Hence, patients receiving milrinone lactate should be observed closely with the use of continuous electrocardiographic monitoring to allow the prompt detection and management of ventricular arrhythmias.

🔴 Adverse Reactions ›
  • ADVERSE REACTIONS Cardiovascular Effects In patients receiving milrinone lactate in Phase II and III clinical trials, ventricular arrhythmias were reported in 12.1%: Ventricular ectopic activity, 8.5%
  • nonsustained ventricular tachycardia, 2.8%
  • sustained ventricular tachycardia, 1% and ventricular fibrillation, 0.2% (2 patients experienced more than one type of arrhythmia). Holter recordings demonstrated that in some patients injection of milrinone lactate increased ventricular ectopy, including nonsustained ventricular tachycardia. Life-threatening arrhythmias were infrequent and when present have been associated with certain underlying factors such as preexisting arrhythmias, metabolic abnormalities (e.g. hypokalemia), abnormal digoxin levels and catheter insertion. Milrinone lactate was not shown to be arrhythmogenic in an electrophysiology study. Supraventricular arrhythmias were reported in 3.8% of the patients receiving milrinone lactate. The incidence of both supraventricular and ventricular arrhythmias has not been related to the dose or plasma milrinone concentration. Other cardiovascular adverse reactions include hypotension, 2.9% and angina/chest pain, 1.2%. In the post marketing experience, there have been rare cases of “torsades de pointes” reported. CNS Effects Headaches, usually mild to moderate in severity, have been reported in 2.9% of patients receiving milrinone lactate. Other Effects Other adverse reactions reported, but not definitely related to the administration of milrinone lactate include hypokalemia, 0.6%
  • tremor, 0.4%
  • and thrombocytopenia, 0.4%. Isolated spontaneous reports of bronchospasm and anaphylactic shock have been received
  • and in the post-marketing experience, liver function test abnormalities and skin reactions such as rash have been reported. Post-Marketing Adverse Event Reports In addition to adverse events reported from clinical trials, the following events have been reported from worldwide post-marketing experience with...

☠️ Overdosage ›

OVERDOSAGE Doses of milrinone lactate may produce hypotension because of its vasodilator effect. If this occurs, administration of milrinone lactate should be reduced or temporarily discontinued until the patient’s condition stabilizes. No specific antidote is known, but general measures for circulatory support should be taken.
