Mechanism of Action

Mechanism of Action

Introduction to how Milrinone works as a phosphodiesterase-3 inhibitor.

Milrinone works by inhibiting PDE3, which elevates intracellular cAMP levels to enhance myocardial contractility and inotropy. It also promotes vasodilation through relaxation of vascular smooth muscle, ultimately improving cardiac output without increasing oxygen demand.

How Milrinone Works

• Inhibits PDE3, increasing intracellular cAMP levels
• Enhances myocardial contractility and inotropy
• Causes vasodilation by relaxing vascular smooth muscle
• Improves cardiac output without raising oxygen demand

This slide illustrates the molecular mechanism of PDE3 inhibition in cardiac cells, which prevents cAMP degradation and leads to elevated cAMP levels that activate PKA for enhanced contractility. It further explains how increased calcium sensitivity improves heart function while promoting vasodilation to reduce vascular resistance and preload.

• PDE3 inhibition blocks cAMP degradation in cardiac cells.
• Elevated cAMP activates PKA, enhancing contractility.
• Increased calcium sensitivity improves heart function.
• Vasodilation reduces vascular resistance and preload.

Clinical Uses

Primary indications for Milrinone in medical practice.

This slide outlines key indications for a medical intervention or therapy, focusing on critical cardiac conditions. It includes treatment of acute decompensated heart failure, hemodynamic support after cardiac surgery, short-term management of cardiogenic shock, and bridging patients to advanced options like transplant.

Indications

• Acute decompensated heart failure treatment
• Post-cardiac surgery hemodynamic support
• Short-term cardiogenic shock management
• Bridge to advanced therapies like transplant

This slide illustrates cardiac physiology, focusing on the drug milrinone, which boosts myocardial contractility by inhibiting PDE3. It highlights how milrinone significantly improves cardiac output and stroke volume while reducing vascular resistance to enhance overall hemodynamics.

This section header slide introduces the topic of Dosing Guidelines. It highlights recommended administration protocols, dosing regimens, and key aspects of patient monitoring.

Dosing Guidelines

Recommended administration protocols, dosing regimens, and essential patient monitoring.

The slide outlines dosing for a medication, starting with a loading dose of 50 mcg/kg IV administered over 10 minutes, followed by a maintenance infusion of 0.375-0.75 mcg/kg/min IV. It also advises adjusting the dose for patients with renal impairment (CrCl <50 mL/min) and emphasizes close monitoring of electrolytes and hemodynamics.

Dosing Information

• Loading dose: 50 mcg/kg IV over 10 minutes
• Maintenance infusion: 0.375-0.75 mcg/kg/min IV
• Adjust dose for renal impairment (CrCl <50 mL/min)
• Monitor electrolytes and hemodynamics closely

This slide serves as a section header titled "Adverse Effects," marking it as the fourth section in the presentation. It includes a subtitle highlighting common and serious side effects that require monitoring.

The slide on side effects lists common adverse reactions including ventricular arrhythmias, hypotension, headache and nausea, and hypokalemia. It also notes a rare occurrence of thrombocytopenia.

Side Effects

• Ventricular arrhythmias
• Hypotension
• Headache and nausea
• Hypokalemia
• Rare thrombocytopenia

This slide serves as a section header titled "Milrinone Contraindications." It includes a subtitle explaining that these are situations where the use of Milrinone should be avoided.

Milrinone Contraindications

Situations where Milrinone should be avoided.

Milrinone is contraindicated in cases of hypersensitivity to the drug or severe obstructive aortic valvular disease. Caution is advised for patients with renal or hepatic impairment, and use should be avoided in those with uncorrected hypokalemia.

Contraindications and Cautions

• Hypersensitivity to Milrinone is contraindicated.
• Severe obstructive aortic valvular disease is contraindicated.
• Use caution in patients with renal or hepatic impairment.
• Avoid use in uncorrected hypokalemia.

Milrinone proves effective in treating acute heart failure but requires vigilant monitoring to ensure safety. Care should be tailored to individual patients, adhering closely to established guidelines for optimal outcomes.

Summary and Key Takeaways

Milrinone: Effective for acute heart failure with vigilant monitoring. Tailor to patients and follow guidelines.
