Phenylephrine is a powerful vasoconstrictor. It is used as a nasal decongestant and cardiotonic agent. Phenylephrine is a postsynaptic α1-receptor agonist with little effect on β-receptors of the heart.
Phenylephrine is a vasoconstricting agent.
Indeed.
Epinephrine is mainly a vasoconstrictor. It acts on alpha-adrenergic receptors in blood vessels, causing constriction and increasing blood pressure. However, it can also dilate blood vessels in certain tissues, like skeletal muscle, through its actions on beta-adrenergic receptors.

The active ingredient in phenylephrine is phenylephrine hydrochloride. It is a sympathomimetic amine that primarily acts as a decongestant by constricting blood vessels in the nasal passages, reducing swelling and congestion. Phenylephrine is commonly used in over-the-counter medications to relieve nasal congestion due to colds, allergies, or sinus infections.
