AH-7921 (Doxylam) is an
Side effects and withdrawal
With doses that usually range from 10 to 150 mg, users are likely to experience effects similar to heroin, morphine, and fentanyl such as euphoria and respiratory depression.[1][8] When an overdose occurs users often experience tachycardia, hypertension, and seizures.[7] Mice, dogs, and monkeys, have been used in tests which showed the drug was almost equivalently potent to morphine, and had a very steep dose response curve.[9] Rats given 20 mg doses three times a day for five days, experienced withdrawal symptoms similar to other opioids. Reports have shown users to experience depression and insomnia when withdrawing from this drug.[1]
Chemistry
AH-7921 is commonly found as an off-white solid with a melting point between 215–216º Celsius.[1] It is one single covalently bonded unit with 4 rotatable bonds. It also has two hydrogen bond acceptors, and one hydrogen bond donor.[10]
Use
Although AH-7921 was extensively studied in vitro and in animals, though not in humans, by the developing company, it was never sold commercially for medical use. In 2013, AH-7921 was discovered to have been used as an active ingredient in "
A 2018 review of published case reports found a total of 14 cases, of which 13 resulted in death.[15] The oral route of administration was reported in two cases, and most cases reported use of concomitant pharmaceutical agents. Postmortem autopsies found that pulmonary edema was the most common finding, with nine of the cases having heavier lungs. Overall, fatalities occurred with low and high concentrations of AH-7921 in femoral blood.[15]
Legality
AH-7921 was made a Prohibited Substance (Schedule 9 of the Standard for the Uniform Scheduling of Medicines and Poisons) in Australia in May 2014.[16] Although this amendment was repealed in June 2014,[17] which simply means the amendment document ceases, but the actual scheduling is permanent as part of the main document (all SUSMP amendments cease after a few weeks). It may, however, still be a banned import.
AH-7921 has been illegal to distribute in Israel since December 2013.[18]
In the UK, AH-7921 was included as a Class A drug in January 2015 as part of The Misuse of Drugs Act 1971 (Amendment) (No. 2) Order 2014.[19]
In Brazil, AH-7921 has been an illegal drug since May 2015.[20]
As of October 2015 AH-7921 is a controlled substance in China.[21]
AH-7921 is banned in the Czech Republic.[22]
In the United States, AH-7921 was placed into Schedule I of the Controlled Substances Act on May 16, 2016, due to its lack of medical use.[6][23] Furthermore, any person who wishes to manufacture, distribute, import, export, research, and educate using the substance, must be registered by the Drug Enforcement Administration.[6]
The Canadian Controlled Drugs and Substances Act was amended in 2016 to include the substance as a Schedule I substance. Possession without legal authority can result in maximum 7 years imprisonment. Further, Health Canada amended the Food and Drug Regulations in May, 2016 to classify AH-7921 as a restricted drug.[24] Only those with a law enforcement agency, person with an exemption permit or institutions with Minister's authorization may possess the drug in Canada.
