Dihydroetorphine
Dihydroetorphine was developed by K. W. Bentley at McFarlan-Smith in the 1960s and is a potent opioid analgesic used mainly in China. It is a derivative of the better-known opioid etorphine, a very potent veterinary painkiller and anesthetic medication used primarily for the sedation of large animals such as elephants, giraffes, and rhinos. Dihydroetorphine is a semi-synthetic opioid used mainly as a strong painkiller for humans. It is several thousand times stronger than morphine (between 1000× and 12000× more potent depending what method is used for comparison), although it is poorly absorbed when taken orally. Sublingual forms of dihydroetorphine are used in China at doses ranging from 20 to 40 μg repeated every 3–4 hours, and are reported to cause strong analgesia and relatively mild side effects compared to other opioids, although all the usual opioid side effects such as dizziness, sedation, nausea, constipation, and respiratory depression can occur.

Acetorphine
Acetorphine is a potent opioid analgesic, up to 8700 times stronger than morphine by weight. It is a Derivative (chemistry), derivative of the more well-known opioid etorphine, which is used as a very potent veterinary painkiller and anesthetic medication, primarily for the sedation of large animals such as elephants, giraffes and rhinos. Acetorphine was developed in 1966 by the Reckitt research group that developed etorphine. Acetorphine was developed for the same purpose as etorphine itself, namely as a strong tranquilizer for use in immobilizing large animals in veterinary medicine. Despite showing some advantages over etorphine, for instance producing less toxic side effects in giraffes, acetorphine was never widely adopted for veterinary use, and etorphine (along with other tranquilizers such as carfentanil and azaperone) remains the drug of choice in this application. Legal status Australia Acetorphine is a schedule 9 substance in Australia under the Standard for the Unifo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Opioid
Opioids are a class of Drug, drugs that derive from, or mimic, natural substances found in the Papaver somniferum, opium poppy plant. Opioids work on opioid receptors in the brain and other organs to produce a variety of morphine-like effects, including analgesic, pain relief. The terms "opioid" and "opiate" are sometimes used interchangeably, but the term "opioid" is used to designate all substances, both natural and synthetic, that bind to opioid receptors in the brain. Opiates are alkaloid compounds naturally found in the opium poppy plant ''Papaver somniferum''. Medically they are primarily used for pain relief, including anesthesia. Other medical uses include suppression of diarrhea, replacement therapy for opioid use disorder, and Cold medicine, suppressing cough. The opioid receptor antagonist naloxone is used to reverse opioid overdose. Extremely potent opioids such as carfentanil are approved only for Veterinary medicine, veterinary use. Opioids are also frequently use ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Morphine
Morphine, formerly also called morphia, is an opiate that is found naturally in opium, a dark brown resin produced by drying the latex of opium poppies (''Papaver somniferum''). It is mainly used as an analgesic (pain medication). There are multiple methods used to administer morphine: oral; sublingual administration, sublingual; via inhalation; intramuscular, injection into a muscle, Subcutaneous injection, injection under the skin, or injection into the spinal cord area; transdermal; or via rectal administration, rectal suppository. It acts directly on the central nervous system (CNS) to induce analgesia and alter perception and emotional response to pain. Physical and psychological dependence and tolerance may develop with repeated administration. It can be taken for both acute pain and chronic pain and is frequently used for pain from myocardial infarction, kidney stones, and during Childbirth, labor. Its maximum effect is reached after about 20 minutes when administ ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Substance Use Disorder
Substance use disorder (SUD) is the persistent use of drugs despite substantial harm and adverse consequences to self and others. Related terms include ''substance use problems'' and ''problematic drug or alcohol use''. Along with substance-induced disorders (SID) they are encompassed in the category substance-related disorders. Substance use disorders vary with regard to the average age of onset. It is not uncommon for those who have SUD to also have other mental health disorders. Substance use disorders are characterized by an array of mental, emotional, physical, and behavioral problems such as chronic guilt; an inability to reduce or stop consuming the substance(s) despite repeated attempts; operating vehicles while intoxicated; and physiological withdrawal symptoms. Drug classes that are commonly involved in SUD include: alcohol (alcoholism); cannabis; opioids; stimulants such as nicotine (including tobacco), cocaine and amphetamines; benzodiazepines; barbiturates; a ...

Hydroxyarenes
Phenol (also known as carbolic acid, phenolic acid, or benzenol) is an aromatic organic compound with the molecular formula . It is a white crystalline solid that is volatile and can catch fire. The molecule consists of a phenyl group () bonded to a hydroxy group (). Mildly acidic, it requires careful handling because it can cause chemical burns. It is acutely toxic and is considered a health hazard. Phenol was first extracted from coal tar, but today is produced on a large scale (about 7 million tonnes a year) from petroleum-derived feedstocks. It is an important industrial commodity as a precursor to many materials and useful compounds, and is a liquid when manufactured. It is primarily used to synthesize plastics and related materials. Phenol and its chemical derivatives are essential for production of polycarbonates, epoxies, explosives such as picric acid, Bakelite, nylon, detergents, herbicides such as phenoxy herbicides, and numerous pharmaceutical dru ...

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. Tables of this general type are also available for NSAIDs, benzodiazepines, depressants, stimulants, anticholinergics and others. Format Equianalgesic tables are available in different formats, such as pocket-sized cards for ease of reference. A frequently-seen format has the drug names in the left column, the route of administration in the center columns and any notes in the right column. Purpose There are several reasons for switching a patient to a different pain medication. These include practical considerations such as lower cost or unavailability of a drug at the patient's preferred pharmacy, or medical reasons such as lack of effectiveness of the current drug or to minimize adverse effects. Some patients requ ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
List Of Fentanyl Analogues
The following is a list of fentanyl Structural analog, analogues (sometimes referred to as fentalogs), and includes both compounds developed by pharmaceutical companies for legitimate medical use, and those which have been sold as designer drugs. The latter have been reported to national drug control agencies such as the Drug Enforcement Administration, DEA, and some to transnational agencies such as the EMCDDA and UNODC. This is not a comprehensive or exhaustive list of fentanyl analogues, as more than 1400 compounds from this family have been described in the scientific and patent literature. However, this list does include many notable compounds that have reached late-stage human clinical trials, and compounds which have been sold as designer drugs, as well as representative examples of significant structural variations reported in the scientific and patent literature. The structural variations among fentanyl analogues can impart profound pharmacological differences between each ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Carfentanil
Carfentanil or carfentanyl, formerly sold under the brand name Wildnil, is an extremely potent opioid analgesic used in veterinary medicine to anesthetize large animals such as elephants and rhinoceroses. It is a structural analogue of the synthetic opioid analgesic fentanyl.. It is typically administered in this context by tranquilizer dart. Carfentanil has also been used in humans to image opioid receptors. It has additionally been used as a recreational drug, typically by injection, insufflation, or inhalation. Deaths have been reported in association with carfentanil. Effects and side effects of carfentanil in humans are similar to those of other opioids and include euphoria, relaxation, pain relief, pupil constriction, drowsiness, sedation, slowed heart rate, low blood pressure, lowered body temperature, loss of consciousness, and suppression of breathing. The effects of carfentanil, including overdose, can be reversed by the opioid antagonists naloxone and naltr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Thienorphine
Thienorphine is a very potent, extremely long-acting, orally-active opioid analgesic with mixed agonist–antagonist properties which was developed by the Beijing Institute of Pharmacology and Toxicology as a potential treatment for opioid dependence. It is a high-affinity, balanced ligand of the μ- (Ki = 0.22 nM), δ- (Ki = 0.69 nM), and κ-opioid receptors (Ki = 0.14 nM), behaving as a partial agonist of the μ- ( Emax = 19%–28%) and κ-opioid receptors (Emax = 65–75%) and as an antagonist of the δ-opioid receptor. It also possesses relatively low affinity for the nociceptin receptor (Ki = 36.5 nM), where it acts as an antagonist.
