Polyadrenaline

Polyadrenaline is a synthetic version of the hormone epinephrine, also known as adrenaline. It is designed as a stimulant which can aid in the revival of a patient who has died or is near death.

Dr. Beverly Crusher used twenty-five cc polyadrenaline to assist Worf's Klingon physiology in reviving his systems after his entire spinal column was replaced by the genitronic replicator in 2368. (TNG: "Ethics")
