Our factory produces premium yellowish carfentanyl for veterinary uses.
Carfentanil or carfentanyl is an analog of the synthetic opioid analgesic fentanyl. A unit of carfentanil is 100 times as potent as the same amount of fentanyl, 5,000 times as potent as a unit of heroin and 10,000 times as potent as a unit of morphine.
The toxicity of carfentanil in humans and its ready commercial availability has aroused concerns over its potential use as a weapon of mass destruction by rogue nations and terrorist groups
Carfentanil (also known as Carfentanyl; 4-carbomethoxyfentanyl; R33799) is an analog of the synthetic opioid analgesic Fentanyl. Carfentanil was first synthesized in 1974 by a team of chemists at Janssen Pharmaceutica which included Paul Janssen.
The effect of Carfentanil exceeds Fentanyl and Morphine in 100 and 10000 times, respectively. Median analgesic activity of ED50 for Carfentanil with intravenous administration to rats is 0.41 μg / kg, the effect on the human body begins already with 1 μg.
In 2012, a team of researchers at the British chemical and biological defence laboratories at Porton Down found carfentanil and remifentanil in clothing from two British survivors of the 2002 Moscow theater hostage crisis and in the urine from a third survivor. The team concluded that the Russian military used an aerosol mist of carfentanil and remifentanil to subdue Chechen hostage takers.
Authors of a previous paper in the Annals of Emergency Medicine surmised from the available evidence that the Moscow emergency services had not been informed of the use of the agent, but were instructed to bring opioid antagonists. Not knowing to expect hundreds of patients exposed to high doses of strong opioids, the emergency workers did not bring enough naloxone or naltrexone (the two most commonly-used opioid antagonists) to counteract the carfentanil and remifentanil and save the lives of many of the victims. 125 people exposed to the gas used in the rescue attempt are confirmed to have died from both respiratory failure and aerosol inhalation during the incident. The authors state that, assuming carfentanil and remifentanil were the only active ingredients of the knockout gas, the worst danger to the theater victims would have been apnea (loss of breathing), and that mechanical ventilation and/or treatment with opioid antagonists could have saved many lives.
