fentanyl and Body Weight

fentanyl has been researched along with Body Weight in 77 studies

Fentanyl: A potent narcotic analgesic, abuse of which leads to habituation or addiction. It is primarily a mu-opioid agonist. Fentanyl is also used as an adjunct to general anesthetics, and as an anesthetic for induction and maintenance. (From Martindale, The Extra Pharmacopoeia, 30th ed, p1078)
fentanyl : A monocarboxylic acid amide resulting from the formal condensation of the aryl amino group of N-phenyl-1-(2-phenylethyl)piperidin-4-amine with propanoic acid.

Body Weight: The mass or quantity of heaviness of an individual. It is expressed by units of pounds or kilograms.
