Fentanyl is a potent synthetic opioid analgesic which is active at very low doses. It has a rapid onset and short duration of action, and is used in the treatment of pain as well as in anesthesia.
Fentanyl is a fully synthetic opioid, and was first synthesized in 1960. Fentanyl is approximately 100 times more potent than morphine, and dosages are often given in micrograms (symbol: µg or mcg); where 1000 micrograms is equal to 1 milligram (mg). Fentanyl was first used in the 1960s as an anesthetic under the brand name Sublimaze. It was not until the mid-1990s that fentanyl was introduced for widespread use with the introduction of a transdermal patch under the brand name Duragesic. During the next decade, quick-acting prescription formulations of fentanyl were introduced, such as the Actiq lollipop and Fentora buccal tablets. Currently, fentanyl is the most widely used synthetic opiate medication.
The transdermal patches are the most common form of fentanyl sold on the street. Abusers will cut open a patch to access the fentanyl gel inside, then usually either smoke, or rub a small amount on their gums and inside of their cheek. Since the patches are designed to release small amounts of fentanyl over a period of 72 hours, cutting open a patch exposes all of the fentanyl at once. If a user is not careful, he or she could easily use too large of an amount and accidentally overdose. Newer patches that are manufactured are designed with a different system then the gel reservoir, making it harder to cut open and extract all the gel containing the fentanyl. Fentanyl has also been sold on the street as heroin or sold combined with heroin, leading to some overdose deaths as a result.
