Benzylmorphine is a semi-synthetic opiate
narcoticThe term narcotic originally referred medically to any psychoactive compound with any sleep-inducing properties. In the United States of America it has since become associated with opioids, commonly morphine and heroin and their derivatives, such as hydrocodone. The term is, today, imprecisely...

myrophineMyrophine is an opiate analogue that was developed in 1952. It is a derivative of morphine.Myrophine is substituted with a 3-benzyl group and a 6-myristyl chain. It is metabolised to form benzylmorphine and then further to morphine, and so is a long-acting prodrug for morphine, but with a slow...
, formed in the liver. It has a metabolic fate similar to that of codeine.
Benzylmorphine is used as the hydrochloride (free base conversion ratio 0.91) and methylsulphonate(0.80) and has a US DEA Administrative Controlled Substance Control Number of 9052.
