What is Fentanyl?
By Dr Ananya Mandal, MD
Fentanyl is a synthetic opioid drug that is used as a potent analgesic or anesthetic adjuvant. The agent is available under various brand names including Duragesic, Sublimaze, Actiq, Onsolis, Instanyl and Fentora.
Fentanyl has a rapid onset of action, which lasts only for a short time. The drug is widely used in the management of breakthrough pain as well as an anesthetic. Fentanyl is also used in the form of a transdermal patch to manage chronic pain. The drug is released by the patch into the body fats, from where it slowly moves into the bloodstream over two or three days, therefore providing long-term pain relief.
