Quizplus · Accepted Answer

Phenylephrine is a nasal decongestant that constricts blood vessels in the nasal passages, reducing inflammation and congestion. When administered intranasally, it can provide quick and targeted relief of nasal congestion. Epinephrine is typically used for severe allergic reactions and is not usually administered intranasally for congestion relief. Propranolol is a beta-blocker used to treat high blood pressure and heart conditions, and physostigmine is a cholinesterase inhibitor used to treat certain eye conditions and myasthenia gravis. Neither of these medications would be effective for relieving nasal congestion.
