Atropine in shock
Atropine acts by blocking parasympathetic effects on the heart. Its effect is to increase cardiac output by increasing heart rate. Atropine is particularly helpful in patients with hypoperfusion from bradycardia secondary to neurogenic shock.
Because the drug has no effect on peripheral vasculature, atropine is often co-administered with agents that increase blood pressure.
Which of the following statements about atropine is FALSE?
Extra info: Atropine is a competitive antagonist of the muscarinic acetylcholine receptors. This fits with atropine being a parasympatholytic drug and blocking the vagal activity on the heart (because the main action of the vagus nerve of the parasympathetic system on the heart is to decrease the heart rate).
