  2. Pantopon - Wikipedia

    en.wikipedia.org/wiki/Pantopon

    Pantopon, also known as Opium Alkaloids Hydrochlorides, is a preparation of opiates made up of all of the alkaloids present in opium in their natural proportions as hydrochlorides salts. [ 1 ] [ 2 ] [ 3 ] It can sometimes be tolerated by people who are allergic to morphine .

  3. Thebaine - Wikipedia

    en.wikipedia.org/wiki/Thebaine

    Thebaine (paramorphine), also known as codeine methyl enol ether, is an opiate alkaloid, its name coming from the Greek Θῆβαι, Thēbai (Thebes), an ancient city in Upper Egypt. A minor constituent of opium , thebaine is chemically similar to both morphine and codeine , but has stimulatory rather than depressant effects.

  4. Opiate - Wikipedia

    en.wikipedia.org/wiki/Opiate

    Papaverine, noscapine, and approximately 24 other alkaloids are also present in opium but have little to no effect on the human central nervous system. Alkaloids that have no effect on the central nervous system were not always considered to be opiates, but current trend is to refer to all alkaloids derived from opium or poppy straw as such.

    This requires them to increase their drug dosage to maintain the benefit, and that in turn also increases the unwanted side effects. [72] Long-term opioid use can cause opioid-induced hyperalgesia, which is a condition in which the patient has increased sensitivity to pain. [95] All of the opioids can cause side effects. [64]

  6. Morphine - Wikipedia

    en.wikipedia.org/wiki/Morphine

    Opium poppy contains at least 50 different alkaloids, but most of them are of very low concentration. Morphine is the principal alkaloid in raw opium and constitutes roughly 8–19% of opium by dry weight (depending on growing conditions). [84] Some purpose-developed strains of poppy now produce opium that is up to 26% morphine by weight.

  7. Alkaloid - Wikipedia

    en.wikipedia.org/wiki/Alkaloid

    Many synthetic and semisynthetic drugs are structural modifications of the alkaloids, which were designed to enhance or change the primary effect of the drug and reduce unwanted side-effects. [208] For example, naloxone , an opioid receptor antagonist , is a derivative of thebaine that is present in opium .

  8. Opium - Wikipedia

    en.wikipedia.org/wiki/Opium

    Opium (or poppy tears, scientific name: Lachryma papaveris) is dried latex obtained from the seed capsules of the opium poppy Papaver somniferum. [4] Approximately 12 percent of opium is made up of the analgesic alkaloid morphine, which is processed chemically to produce heroin and other synthetic opioids for medicinal use and for the illegal drug trade.

  9. Laudanum - Wikipedia

    en.wikipedia.org/wiki/Laudanum

    The pharmacological effects of opium tincture are due principally to its morphine content. The quantity of the papaverine and codeine alkaloids in opium tincture is too small to have any demonstrable central nervous system effect. [31]
