Routes  ?

Thiofentanyl is an opioid analgesic that is an analogue of fentanyl. In pharmacology and toxicology, a route of administration is the path by which a drug, fluid, poison or other substance is brought into contact with the body 1. ... This article needs additional references or sources to facilitate its verification. ... This article or section does not adequately cite its references or sources. ... An analog is in chemistry a chemical closely related to another usually sharing the same nucleus. ... Fentanyl is an opioid analgesic, first synthesized by Janssen Pharmaceutica (Belgium) in the late 1950s, with an analgesic potency of about 80 times that of morphine. ...

Thiofentanyl was sold briefly on the black market in the early 1980s, before the introduction of the Federal Analog Act which for the first time attempted to control entire families of drugs based on their structural similarity rather than scheduling each drug individually as they appeared. [1] Thiofentanyl is made with the same synthetic route as fentanyl, but by substituting 2-(2-bromoethyl)thiophene for phenethyl bromide in the synthesis. The Federal Analog Act is a controversial section of the DEA Controlled Substances Act, allowing any chemical substantially similar to an illegal drug (in Schedule I or II) to be treated as if it were also in Schedule I, but only if it is intended for human consumption. ...

Thiofentanyl has similar effects to fentanyl. Side effects of fentanyl analogues are similar to those of fentanyl itself, which include itching, nausea and potentially serious respiratory depression which can be life-threatening. An itch (Latin: pruritus) is a sensation felt on an area of skin that makes a person or animal want to scratch it. ... For the Beck song, see Nausea (song). ... In medicine, hypoventilation exists when ventilation is inadequate to perform gas exchange. ...
