Final answer:
Adrenergic drugs, particularly epinephrine, are used to treat anaphylactic shock by improving blood pressure and breathing, making it crucial for patients with severe allergies to carry an epinephrine injector.
Step-by-step explanation:
The treatment for anaphylactic shock, which is also known as anaphylaxis, involves the use of an adrenergic drug, specifically epinephrine. Epinephrine counteracts the severe allergic reaction by raising blood pressure, relaxing bronchial smooth muscle, modulating heart rate, and reducing swelling to improve breathing and prevent suffocation. It is important for patients with known severe allergies to carry an automatic epinephrine injector for emergency self-administration, especially when they are far from medical facilities.
