Actiq
(AK-tik)
A drug used to treat severe pain in people with chronic conditions, such as cancer, who have not gotten better after treatment with other opioids. It is also used to treat pain after surgery. Actiq works by binding to mu opioid receptors in the central nervous system, which blocks pain signals and alters how the body responds to pain. It is a type of synthetic opioid agonist that acts as an analgesic (pain reliever). Also called fentanyl citrate.
