Morphology
phenylephrine = epinephrine (opaque) = phenyl + epinephrine
Although morphologically formed by adding the chemical combining form 'phenyl' to 'epinephrine', the name is a specialized chemical/medical term and its pharmacological meaning is not inferable by average learners.
Etymology
Phenylephrine comes from two parts: phenyl, a name for a simple chemical 'ring' often found in medicines, and ephrine, which links it to epinephrine ('adrenaline'). So it's a man-made drug that works like adrenaline to make blood vessels smaller, which explains why doctors use it to raise blood pressure, make pupils larger, or clear a blocked nose.
