What type of drug is Oxandrolone that was found in the system of  Cinthya Domínguez in 2015?
Oxandrolone Oxandrolone (brand names Oxandrin, Anavar, Lonavar, others), is a synthetic, orally active anabolic-androgenic steroid (AAS) that first became available as a prescription drug in the United States in 1964. It is a 17α-methylated derivative of dihydrotestosterone (DHT) that has an oxygen atom in place of the carbon at the 2 position.
Acetylmethadol Acetylmethadol, also known as methadyl acetate, is a synthetic opioid analgesic. It is a racemic mixture of alphacetylmethadol (α-acetylmethadol) and betacetylmethadol (β-acetylmethadol), which are in turn racemic mixtures of levacetylmethadol (LAAM; -α-acetylmethadol) and -α-acetylmethadol and -β-acetylmethadol and -β-acetylmethadol, respectively. Hence, acetylmethadol has four possible optical isomers. All of these isomers have been shown to partially or fully substitute for the discriminative stimulus effects of heroin in rats, and thus it can be inferred that, in addition to LAAM which is used clinically as such, they are all likely to be active opioid analgesics in humans.
