  2. Semisynthesis - Wikipedia

    en.wikipedia.org/wiki/Semisynthesis

    Semisynthesis, or partial chemical synthesis, is a type of chemical synthesis that uses chemical compounds isolated from natural sources (such as microbial cell cultures or plant material) as the starting materials to produce novel compounds with distinct chemical and medicinal properties.

  3. Opioid - Wikipedia

    en.wikipedia.org/wiki/Opioid

    Opiate is properly limited to the natural alkaloids found in the resin of the opium poppy although some include semi-synthetic derivatives. [24] [25] Other opioids are semi-synthetic and synthetic drugs such as hydrocodone, oxycodone, and fentanyl; antagonist drugs such as naloxone; and endogenous peptides such as endorphins. [26]

  4. Synthetic drug - Wikipedia

    en.wikipedia.org/wiki/Synthetic_drug

    The adverse effects of synthetic drugs are hard to determine as they usually contain other chemicals with variable concentrations and human studies are limited. Synthetic cannabinoids can cause cardiovascular problems such as tachyarrhythmia, seizures, psychological disorders and potential carcinogenic effects. Addiction and withdrawal symptoms ...

  5. Equianalgesic - Wikipedia

    en.wikipedia.org/wiki/Equianalgesic

    An equianalgesic chart is a conversion chart that lists equivalent doses of analgesics (drugs used to relieve pain). Equianalgesic charts are used for calculation of an equivalent dose (a dose which would offer an equal amount of analgesia) between different analgesics. [1]

  6. List of benzodiazepines - Wikipedia

    en.wikipedia.org/wiki/List_of_benzodiazepines

    The tables below contain a sample list of benzodiazepines and benzodiazepine analogs that are commonly prescribed, with their basic pharmacological characteristics, such as half-life and equivalent doses to other benzodiazepines, also listed, along with their trade names and primary uses.

  7. Opiate - Wikipedia

    en.wikipedia.org/wiki/Opiate

    A chart outlining the structural features that define opiates and opioids, including distinctions between semi-synthetic and fully synthetic opioid structures. An opiate is an alkaloid substance derived from opium (or poppy straw). [1]

  8. List of benzimidazole opioids - Wikipedia

    en.wikipedia.org/wiki/List_of_benzimidazole_opioids

    The structure-activity relationship of the drug class has been explored to a reasonable extent. The optimal substitution pattern is fairly tightly defined (i.e. N,N-diethyl on the amine nitrogen, 4-ethoxy on the benzyl ring and 5-nitro on the benzimidazole ring), but even derivatives incorporating only some of these features are still potent opioids.

  9. Opioid epidemic in the United States - Wikipedia

    en.wikipedia.org/wiki/Opioid_epidemic_in_the...

    A chart outlining the structural features that define opiates and opioids, including distinctions between semi-synthetic and fully synthetic opiate structures. Oxycodone was first made available in the United States in 1939. In the 1970s, the FDA classified oxycodone as a Schedule II drug, indicating a high potential for non-medical use and ...
