What is the mechanism of action of adrenaline?
Mechanism of action/pharmacology
Adrenaline is a non-selective adrenergic agonist with potent β1 and moderate α1 and β2-receptor activity. Increased myocardial force of contraction (positive inotrope) and heart rate (positive chronotrope) occur as a result of β1 receptor stimulation.
What are contraindications for adrenaline?
Epinephrine is contraindicated in patients with known hypersensitivity to sympathomimetic amines, in patients with angle closure glaucoma, and patients in shock (nonanaphylactic).
What is the contraindications of adrenaline injection?
Adrenaline is contraindicated in patients with shock (other than anaphylactic shock), organic heart disease, or cardiac dilatation, as well as most patients with arrhythmias, organic brain damage, or cerebral arteriosclerosis. Adrenaline injection is contraindicated in patients with narrow angle glaucoma.
What are the indications of atropine?
Atropine or atropine sulfate carries FDA indications for anti-sialagogue/anti-vagal effect, organophosphate/muscarinic poisoning, and bradycardia. Atropine acts as a competitive, reversible antagonist of muscarinic receptors: an anticholinergic drug.
When do you administer adrenaline?
People with potentially serious allergies are often prescribed adrenaline auto-injectors to carry at all times. These can help stop an anaphylactic reaction becoming life threatening. They should be used as soon as a serious reaction is suspected, either by the person experiencing anaphylaxis or someone helping them.

Primary adrenal insufficiency — Treatment of adrenal insufficiency requires a daily dose of a glucocorticoid and mineralocorticoid pills, usually for life. Androgen replacement may be recommended for women. The goal of treatment is to stabilize hormone levels and relieve symptoms.
How do you test adrenal function?
Blood and urine tests help measure the amount of adrenal hormones, which can detect a functional tumor. A computed tomography (CT or CAT) scan or a magnetic resonance imaging (MRI) scan may be useful in diagnosing an adrenal gland tumor and determining whether it is cancerous.
What is the most common cause of adrenal insufficiency?
Primary adrenal insufficiency is most often caused when your immune system attacks your healthy adrenal glands by mistake. Other causes may include: Cancer. Fungal infections.
What are the types of adrenal insufficiency?
Adrenal insufficiency can be primary, secondary, or tertiary:

- Secondary adrenal insufficiency. This starts when the pituitary gland doesn’t make enough of the hormone ACTH (adrenocorticotropin). …
- Tertiary adrenal insufficiency.
What is the best test for adrenal insufficiency?
ACTH Stimulation Test This is the most specific test for diagnosing adrenal insufficiency. Blood cortisol levels are measured before and after a synthetic form of adrenocorticotrophic hormone (ACTH), a hormone secreted from the anterior pituitary, is given by injection.
