Narcolytic metabolase

From Halopedia, the Halo wiki

Narcolytic metabolase is a human drug. It is an enzyme that, when injected into a person, consumes all analgesic agents in the patient's bloodstream, waking them up if they were sedated.


Dr. Catherine Halsey used narcolytic metabolase on a sedated Kelly-087 when they arrived at Onyx aboard the Beatrice.[1]
