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 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.
