Phil is stung on his cheek by a wasp. Because Phil is allergic to wasp venom, his throat begins to swell and his respiratory passages constrict. Would acetylcholine or epinephrine be more helpful in relieving his symptoms? Why?

Epinephrine is used to treat symptoms of type I hypersensitivity, systemic anaphylaxis. People with hypersensitivity to bee stings may experience anaphylaxis.

Hi,

Well what is each used for? Acetylcholine is a neutrotransmitter which triggers muscle contraction; I don't think that'd help Phil with his constricted airways!

Epinephrine (adrenaline) is able to bind to beta2 adrenergic receptors in bronchial smooth muscle leading to muscle relaxation. That sounds like a better idea. In fact, this is what EpiPens do for allergic reactions.
