Carbonate derivatives of 14β-hydroxycodeine "viz., 14β-hydroxy-6-O-(methoxycarbonyl)codeine, 6-O-methoxycarbonyl-14β-(methoxycarbonyloxy)codeine, and 14β-acetoxy-6-O-methoxy-carbonylcodeine, potential substrates for ring C modification in morphinane (sic) alkaloids, were synthesized for the first time." Russian Chemical Bulletin.
Simply switching the patient from 40 mg of morphine to 10 mg of levorphanol would be dangerous due to dose accumulation, and hence frequency of administration should also be taken into account. There are other concerns about equianalgesic charts. Many charts derive their data from studies conducted on opioid-naive patients.
It combines "opium" + "-oid" meaning "opiate-like" ("opiates" being morphine and similar drugs derived from opium). The first scientific publication to use it, in 1963, included a footnote stating, "In this paper, the term, 'opioid', is used in the sense originally proposed by George H. Acheson (personal communication) to refer to any chemical ...

Related to codeine in other ways are codoxime, thebacon, codeine-N-oxide (genocodeine), related to the nitrogen morphine derivatives as is codeine methobromide, and heterocodeine, which is a drug six times stronger than morphine and 72 times stronger than codeine due to a small re-arrangement of the molecule, namely moving the methyl group from ...

The methyl group that makes morphine into codeine can be removed or added back, or replaced with another functional group like ethyl and others to make codeine analogues of morphine-derived drugs and vice versa. Codeine analogues of morphine-based drugs often serve as prodrugs of the stronger drug, as in codeine and morphine, hydrocodone and ...
