Question

Anaphylactic shock is treated with which of the following drugs:
1. Adrenaline
2. Propranolol
3. Enalapril
4. Digoxin

Answer 1

"Correct Answer - Option 1 : Adrenaline

CONCEPT: 

• Anaphylactic shock is a rare but severe allergic reaction that can be deadly if you don't treat it right away.
• It's most often caused by an allergy to food, insect bites, or certain medications.

 

EXPLANATION:

• The first step for treating anaphylactic shock will likely be injecting epinephrine (adrenaline) immediately.
• Adrenaline has physiological benefits in the treatment of anaphylaxis: stimulation of α adrenoceptors increases peripheral vascular resistance thus improving blood pressure and coronary perfusion, reversing peripheral vasodilation and decreasing angioedema.
• Stimulation of β1 adrenoceptors has both positive inotropic and chronotropic cardiac effects.
• Stimulation of β2 receptors causes bronchodilation.
