Final answer:
The trade name for an epinephrine auto-injector is Epi-Pen®. It is used to treat severe allergic reactions such as anaphylaxis by delivering a pre-measured dose of epinephrine quickly and effectively.
Step-by-step explanation:
The trade name for an epinephrine auto-injector is D. Epi-Pen®. EpiPens® are designed for rapid self-administration in cases of severe allergic reactions, such as anaphylaxis. When an individual is exposed to an allergen, it can cause anaphylactic shock, a life-threatening condition that needs to be treated immediately with an injection of epinephrine. This medication helps to raise blood pressure, relax bronchial muscles, modulate heart rate, and reduce airway swelling.
As epinephrine auto-injectors, EpiPens® provide a pre-measured dose of the drug and can be used through clothing if necessary, offering a critical lifeline until further medical treatment can be obtained. They are prescribed extensively, and those with severe allergies are often advised to carry two EpiPens® with them at all times, even though they have to be replaced each year due to the expiration of the epinephrine they contain.
