BUY Thiafentanil POWDER (A-3080, Thianil) is a highly potent opioid analgesic that is an analog of fentanyl, and was invented in 1986.
It is similar to carfentanil though with a faster onset of effects, shorter duration of action and a slightly lesser tendency to produce respiratory depression.
It is used in veterinary medicine to anesthetise large animals such as impala, usually in combination with other anaesthetics such as ketamine, xylazine or medetomidine to reduce the prevalence of side effects such as muscle rigidity.
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.
Potent pure opioid antagonists such as naltrexone or nalmefene are recommended in the event of accidental human exposure to thiafentanil.
Fentanyl analogues have killed hundreds of people throughout Europe and the former Soviet republics since the
most recent resurgence in use began in Estonia in the early 2000s, and novel derivatives continue to appear.
A new wave of fentanyl analogues and associated deaths began in around 2014 in the US, and have continued to grow
in prevalence; especially since 2016 these drugs have been responsible for hundreds of overdose deaths every week.
Thiafentanil is a Schedule II controlled drug in the USA since August 2016.
