What are adrenergic drugs examples?
Examples of adrenergic drugs which selectively bind to alpha-1 receptors are phenylephrine and oxymetazoline. Selective alpha-2 receptor drugs include methyldopa and clonidine. The key beta-1 selective drug is dobutamine. Lastly, beta-2 selective drugs are bronchodilators, such as albuterol and salmeterol.
What is an important nursing interventions for patients receiving an alpha adrenergic?
These are vital nursing interventions done in patients who are taking alpha-agonists: Do not discontinue abruptly to prevent rebound hypertension. Monitor blood pressure, orthostatic blood pressure, pulse, rhythm, and cardiac output regularly to adjust dose or discontinue the drug of CV effects are severe.
What do adrenergic drugs affect?
Adrenergic drugs stimulate the nerves in your body’s sympathetic nervous system (SNS). This system helps regulate your body’s reaction to stress or emergency.

How they work
- increase blood pressure.
- constrict blood vessels.
- open the airways leading to the lungs.
- increase heart rate.
- stop bleeding.

- Nadolol.
Is atropine an adrenergic?
From the present data, it is suggested that atropine, besides its classical blocker effect at the muscarinic receptor, at high concentration is a specific alpha-adrenergic antagonist.
What is another name for an adrenergic drug?
Adrenergic (Sympathomimetic) Drugs
Naturally occurring molecules that bind to these receptors include epinephrine (11.1), which binds to α1,α2, and β1 receptors, norepinephrine (11.2), which binds to α1, α2, and β1 receptors, and dopamine (11.3), which binds to dopamine receptors as well as to α1 and β1 receptors.
What are the nursing implications of clonidine?
Indications: Clonidine is used to treat hypertension (HTN) and attention deficit hyperactivity disorder (ADHD). Nursing Considerations: Monitor blood pressure and pulse rate frequently. Dosage is usually adjusted to the patient’s blood pressure and can cause hypotension, bradycardia, and sedation.
What are examples of adrenergic agonists?
Adrenergic Agonists
| Drug | Drug Description |
|---|---|
| Methoxamine | An alpha adrenergic agonist used to treat hypotension. |
| Orciprenaline | A beta-2 adrenergic agonist used to treat bronchospasm, asthma, and COPD. |
| Dobutamine | A beta-1 agonist used to treat cardiac decompensation in patients with organic heart disease or from cardiac surgery. |
What are adrenergic antagonist drugs?
Listen to pronunciation. (BAY-tuh-A-dreh-NER-jik an-TA-guh-nist) A type of drug that blocks the action of substances, such as adrenaline, on nerve cells and causes blood vessels to relax and dilate (widen). This allows blood to flow more easily and lowers blood pressure and the heart rate.
Which of the following medications is an adrenergic antagonist?
Drugs that bind to but do not activate ADRENERGIC RECEPTORS. Adrenergic antagonists block the actions of the endogenous adrenergic transmitters EPINEPHRINE and NOREPINEPHRINE.
Adrenergic Antagonists.
| Drug | Drug Description |
|---|---|
| Carteolol | A beta adrenergic antagonist used to treat arrhythmia, angina, hypertension, and glaucoma. |
Is digitalis cholinergic or adrenergic?
Digitalis is a cholinergic agonist, a chemical compound with properties like acetylcholine or the parasympathetic nervous system.
Is atropine adrenergic or cholinergic?
What are nursing considerations for beta blockers?
Nursing Considerations: Nonselective beta blockers must be used cautiously with patients who have co-existing asthma or chronic obstructive pulmonary disease (COPD) because of the effects on Beta-2 receptors that could potentially cause bronchoconstriction. It can also mask symptoms of hypoglycemia in diabetics.
What are the nursing implications for lisinopril?
Possible Lisinopril Nursing Diagnoses
- Risk for Impaired Renal Perfusion related to the mechanism of action of lisinopril.
- Risk for Electrolyte Imbalance (Hyperkalemia) related to the possible side effect of lisinopril.
- Nausea related to the side effect of lisinopril.
- Deficient Knowledge related to a new drug prescription.
Which drugs are antagonists?
An antagonist is a drug that blocks opioids by attaching to the opioid receptors without activating them. Antagonists cause no opioid effect and block full agonist opioids. Examples are naltrexone and naloxone.
What are examples of sympathomimetics?
Examples
- amphetamine (Evekeo)
- benzylpiperazine (BZP)
- cathine (found in Catha edulis)
- cathinone (found in Catha edulis, khat)
- cocaine (found in Erythroxylum coca, coca)
- ephedrine (found in Ephedra)
- lisdexamfetamine (Vyvanse)
- maprotiline (Ludiomil)
Is epinephrine an agonist or antagonist?
Natural hormones stimulate B2 receptors in the body as well as by synthetic compounds; epinephrine (adrenaline) is the most effective natural catecholamine agonist of B2, while norepinephrine (noradrenaline) is less effective on it, and epinephrine is the hormone responsible for B2 receptor stimulation in the …
What are adrenergic agonist drugs?
Adrenergic agonists are drugs that work by mimicking the functioning of the sympathetic nervous system—the part of the nervous system that increases heart rate, blood pressure, breathing rate, and eye pupil size.
What is the difference between adrenergic and cholinergic?
The main difference between the two is their neurotransmitters. For the cholinergic line, acetylcholine (ACh) is used while the adrenergic line makes use of either norepinephrine or epinephrine (also known as adrenaline); no wonder the adrenergic line came to be named as such because adrenaline is involved.
Is digitalis adrenergic or cholinergic?
cholinergic agonist
Digitalis is a cholinergic agonist, a chemical compound with properties like acetylcholine or the parasympathetic nervous system.
What is the difference between cholinergic and adrenergic?
1. Adrenergic involves the use of the neurotransmitters epinephrine and norepinehprine while cholinergic involves acetylcholine. 2. Adrenergic is called the sympathetic line (SNS) while cholinergic is called the parasympathetic line (PNS).
What are nursing considerations for propranolol?
Assess heart rate, ECG, and heart sounds, especially during exercise (See Appendices G, H). Report immediately an unusually slow heart rate (bradycardia) or signs of other arrhythmias, including palpitations, chest discomfort, shortness of breath, fainting, and fatigue/weakness.
What are nursing implications for metoprolol?
Nursing Considerations for Metoprolol
Instruct the patient that extended-release tablets should be swallowed whole and not be crushed, chewed, or cut, unless the tablet is scored. Abrupt withdrawal of the drug may cause myocardial infarction, ventricular dysrhythmias, and ischemia.
What are the nursing implications?
Nursing implications are the possible clinical consequences or effects of implementing the study’s findings (Polit & Beck, 2014). Research may have varied clinical implications.
What are nursing considerations for aspirin?
Assess patient for signs of bleeding (petechiae, ecchymosis, bloody or black stools, bleeding gums). Drink adequate fluids while taking aspirin. Advise patient to avoid alcohol when prescribed high doses of aspirin. Baby aspirin is preferred for acute or prophylactic management of heart disease.
