Adjective:
- Relating to or denoting nerve cells or fibers that release or are affected by epinephrine (adrenaline) or similar substances: This describes physiological processes, receptors, or agents that involve adrenaline-like neurotransmitters.
- Mimicking the action of epinephrine: Used to describe drugs or effects that stimulate the sympathetic nervous system.
Noun:
- A drug or other agent that causes stimulation of the sympathetic nervous system: A substance that produces effects similar to those of epinephrine (adrenaline).
Adjective:
