Summary
Catecholamines are vital in intensive care but excessive use, especially those with beta-adrenergic effects, can harm the heart. Careful titration and monitoring are essential for safe vasopressor therapy.
Area of Science:
- Intensive Care Medicine
- Pharmacology
- Cardiology
Background:
- Catecholamines are frequently used in intensive care for their vasopressor and inotropic effects.
- Their therapeutic benefits are well-established, but risks associated with overuse exist.
Purpose of the Study:
- To review the physiological actions underpinning catecholamine therapy.
- To elucidate the risks of uncritical and excessive catecholamine administration.
Main Methods:
- This is a review article.
- It synthesizes existing evidence on catecholamine effects and risks.
Main Results:
- Adrenergic overstimulation can lead to myocardial damage.
- Catecholamines with strong beta-adrenergic effects (epinephrine, dobutamine, dopamine) may negatively impact severe heart failure, ischemia, and shock.
- Tachycardia can serve as a cardiac risk marker.
Conclusions:
- Norepinephrine therapy, guided by perfusion parameters, is often justified in shock and hemodynamic instability.
- Cardioprotective catecholamine administration requires continuous reevaluation and titration to the lowest effective dose.

2.2K
Adrenergic agonists have diverse therapeutic uses across various medical conditions and emergencies.
Emergency and Intensive Care Unit (ICU) applications: Pressor agents increase blood pressure, heart rate, and contractility in shock and organ failure situations. Dopamine can induce vasodilation and stimulate adrenoceptors. Endogenous catecholamines are effective in treating cardiogenic shock. α2-agonists like clonidine can reverse anesthesia-induced hypertension.

1.8K
Mixed-action adrenergic agonists, like ephedrine and pseudoephedrine, directly and indirectly affect adrenergic receptors. These agents stimulate adrenoceptors and indirectly release stored neurotransmitters, amplifying the adrenergic response.
Ephedrine and pseudoephedrine lack a catecholamine group, making them less susceptible to degradation by metabolic enzymes. They have increased oral bioavailability and lipophilicity, resulting in a longer duration of action. Their response is reduced by...

6.0K
Postganglionic sympathetic fibers (except those supplying the sweat glands) releasing noradrenaline or norepinephrine are called noradrenergic or adrenergic neurons. Noradrenaline, dopamine, adrenaline, or epinephrine are collectively called "catecholamines" as they contain a catechol moiety and an amine side chain. The five stages of neurotransmitter release involve their synthesis, storage, release, reuptake and metabolism.

3.1K
Indirect-acting adrenergic agonists potentiate the effects of endogenous catecholamines through different mechanisms without directly binding to adrenoceptors.
One mechanism involves depleting stored catecholamines by displacing them from synaptic vesicles. These agents, known as "displacers," are transported into vesicles at the expense of noradrenaline. Examples include amphetamine and tyramine, which lack a catechol moiety, resulting in prolonged action, improved oral...

Drugs that mimic the action of endogenous catecholamines like noradrenaline and adrenaline are called adrenergic agonists or sympathomimetics. Based on their mechanism of action, sympathomimetics can be classified as direct-, indirect-, or mixed-acting sympathomimetics. Direct-acting adrenergic agonists activate adrenoceptors without affecting presynaptic neurons, making them independent of neuronal catecholamine-depleting agents like reserpine and guanethidine.

β-receptor blockers significantly impact the cardiovascular system by counteracting catecholamine-induced sympathetic responses. These medications decrease heart rate, contractility, and cardiac output, potentially leading to cardiac depression, life-threatening bradycardia, and death. Therapeutically, β-blockers function as mild antihypertensives and are utilized in treating angina pectoris and cardiac arrhythmias. However, nonselective β-blockers inhibit β2-receptors in...
