Dihydroisocodeine
Dihydroisocodeine is an opioid. The National Research Council of the United States reported in 1941 that isocodeine is one of four isomers of codeine Codeine is an opiate and prodrug of morphine mainly used to treat pain, coughing, and diarrhea. It is also commonly used as a recreational drug. It is found naturally in the sap of the opium poppy, ''Papaver somniferum''. It is typically use ... known at the time ( heterocodeine can be considered a fifth) and DHIC, then in use in Europe as a pharmaceutical, was four times stronger than dihydrocodeine as isocodeine is four times stronger than codeine. The other isomers of codeine are allocodeine and pseudocodeine and they are active drugs as is heterocodeine, which is estimated to be up to 108 times as potent as codeine.

Opioid
Opioids are substances that act on opioid receptors to produce morphine-like effects. Medically they are primarily used for pain relief, including anesthesia. Other medical uses include suppression of diarrhea, replacement therapy for opioid use disorder, reversing opioid overdose, and suppressing cough. Extremely potent opioids such as carfentanil are approved only for veterinary use. Opioids are also frequently used non-medically for their euphoric effects or to prevent withdrawal. Opioids can cause death and have been used for executions in the United States. Side effects of opioids may include itchiness, sedation, nausea, respiratory depression, constipation, and euphoria. Long-term use can cause tolerance, meaning that increased doses are required to achieve the same effect, and physical dependence, meaning that abruptly discontinuing the drug leads to unpleasant withdrawal symptoms. The euphoria attracts recreational use, and frequent, escalating recreational ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Isocodeine
Isocodeine is an opioid research chemical related to codeine. It is an epimer of codeine that can be prepared from codeine via a Mitsunobu reaction. Dozens of derivatives and analogs of isocodeine and the related compound isomorphine have been produced. One of these, dihydroisocodeine Dihydroisocodeine is an opioid. The National Research Council of the United States reported in 1941 that isocodeine is one of four isomers of codeine Codeine is an opiate and prodrug of morphine mainly used to treat pain, coughing, and di ... is a pharmaceutical four times stronger than dihydrocodeine and thus six times stronger than codeine which was used more extensively in the past in Continental Europe and other locales. Other isomers of codeine include allocodeine, pseudocodeine, heterocodeine and substances with intermediate qualities such as pseudoallocodeine and formylallocodeine can be prepared in the laboratory.Report of the Committee On Drug Addiction 1929-1941 with Monograph ...

Codeine
Codeine is an opiate and prodrug of morphine mainly used to treat pain, coughing, and diarrhea. It is also commonly used as a recreational drug. It is found naturally in the sap of the opium poppy, ''Papaver somniferum''. It is typically used to treat mild to moderate degrees of pain. Greater benefit may occur when combined with paracetamol (acetaminophen) or a nonsteroidal anti-inflammatory drug (NSAID) such as aspirin or ibuprofen. Evidence does not support its use for acute cough suppression in children or adults. In Europe, it is not recommended as a cough medicine in those under 12 years of age. It is generally taken by mouth. It typically starts working after half an hour, with maximum effect at two hours. Its effects last for about four to six hours. Codeine exhibits abuse potential similar to other opioid medications. Common side effects include vomiting, constipation, itchiness, lightheadedness, and drowsiness. Serious side effects may include breathing difficult ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Heterocodeine
Heterocodeine (6-methoxymorphine) is an opiate derivative, the 6- methyl ether of morphine, and a structural isomer of codeine; it is called "hetero-" because it is the reverse isomer of codeine. Heterocodeine was first synthesised in 1932 and first patented in 1935. It can be made from morphine by selective methylation. Codeine is the natural mono-methyl ether, but must be metabolized for activity (that is, it is a prodrug). In contrast the semi-synthetic mono-methyl ether, heterocodeine is a direct agonist. The 6,7,8,14 tetradehydro 3,6 methyl di-ether of morphine is thebaine. Heterocodeine is 6 times more potent than morphine due to having a substitution at the 6-hydroxy position, in a similar manner to 6-acetylmorphine. The drug methyldihydromorphine (dihydroheterocodeine) is a derivative of heterocodeine. Like the morphine metabolite morphine-6-glucuronide, 6-position branches (esters or ethers) of morphine bind to the otherwise unagonized human mu receptor subtype mu-3 ( ...
