Diacetyldihydromorphine
Diacetyldihydromorphine (also known as Paralaudin, dihydroheroin, acetylmorphinol) is a potent opiate derivative developed in Germany in 1928 which is rarely used in some countries for the treatment of severe pain such as that caused by terminal cancer, as another form of diacetylmorphine (also commonly known as Heroin). Diacetyldihydromorphine is fast-acting and longer-lasting than diamorphine, with a duration of action of around 4-7 hours. As an ester/analogue of dihydromorphine, diacetyldihydromorphine is presumably a Schedule I/Narcotic controlled substance in the United States but does not have its own ACSCN or annual production quota. It does appear in the German Betäubungsmittelgesetz and other European controlled-substances laws. Diacetyldihydromorphine is quickly metabolized by plasma esterase enzymes into dihydromorphine, in the same way that diamorphine is metabolized into morphine. Diamorphine is 1.50–1.80 times the potency of morphine. It shares with other opioi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Morphine
Morphine is a strong opiate that is found naturally in opium, a dark brown resin in poppies (''Papaver somniferum''). It is mainly used as a analgesic, pain medication, and is also commonly used recreational drug, recreationally, or to make other illicit drug, illicit opioids. There are numerous methods used to administer morphine: oral; sublingual administration, sublingual; via inhalation; intramuscular, injection into a muscle; by Subcutaneous injection, injection under the skin; intravenously; Intrathecally, injection into the space around the spinal cord; 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 Ch ...

Opiate
An opiate, in classical pharmacology, is a substance derived from opium. In more modern usage, the term ''opioid'' is used to designate all substances, both natural and synthetic, that bind to opioid receptors in the brain (including antagonists). Opiates are alkaloid compounds naturally found in the opium poppy plant ''Papaver somniferum''. The psychoactive compounds found in the opium plant include morphine, codeine, and thebaine. Opiates have long been used for a variety of medical conditions with evidence of opiate trade and use for pain relief as early as the eighth century AD. Opiates are considered drugs with moderate to high abuse potential and are listed on various "Substance-Control Schedules" under the Uniform Controlled Substances Act of the United States of America. In 2014, between 13 and 20 million people used opiates recreationally (0.3% to 0.4% of the global population between the ages of 15 and 65). According to the CDC, from this population, there were 47,00 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Diacetylmorphine
Heroin, also known as diacetylmorphine and diamorphine among other names, is a potent opioid mainly used as a recreational drug for its euphoric effects. Medical grade diamorphine is used as a pure hydrochloride salt. Various white and brown powders sold illegally around the world as heroin have variable "cuts". Black tar heroin is a variable admixture of morphine derivatives—predominantly 6-MAM (6-monoacetylmorphine), which is the result of crude acetylation during clandestine production of street heroin. Heroin is used medically in several countries to relieve pain, such as during childbirth or a heart attack, as well as in opioid replacement therapy. It is typically injected, usually into a vein, but it can also be smoked, snorted, or inhaled. In a clinical context, the route of administration is most commonly intravenous injection; it may also be given by intramuscular or subcutaneous injection, as well as orally in the form of tablets. The onset of effects is usually ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Semisynthetic Opioids
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 use of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nicomorphine
Nicomorphine (Vilan, Subellan, Gevilan, MorZet) is the 3,6-dinicotinate ester of morphine. It is a strong opioid agonist analgesic two to three times as potent as morphine with a side effect profile similar to that of dihydromorphine, morphine, and diamorphine. Nicomorphine was first synthesized in 1904 and was patented as Vilan by Lannacher Heilmittel G.m.b.H. of Austria in 1957. Medical Use The hydrochloride salt is available as ampoules of 10 mg/ml solution for injection, 5 mg tablets, and 10 mg suppositories. It is possible that other manufacturers distribute 10 mg tablets and other concentrations of injectable nicomorphine in ampoules and multidose vials. It is used, particularly in the German-speaking countries and elsewhere in Central Europe and some other countries in Europe and the former USSR in particular, for post-operative, cancer, chronic non-malignant and other neuropathic pain. It is commonly used in patient-controlled analgesia (PCA) units ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Acetate Esters
An acetate is a salt formed by the combination of acetic acid with a base (e.g. alkaline, earthy, metallic, nonmetallic or radical base). "Acetate" also describes the conjugate base or ion (specifically, the negatively charged ion called an anion) typically found in aqueous solution and written with the chemical formula . The neutral molecules formed by the combination of the acetate ion and a ''positive'' ion (called a cation) are also commonly called "acetates" (hence, ''acetate of lead'', ''acetate of aluminum'', etc.). The simplest of these is hydrogen acetate (called acetic acid) with corresponding salts, esters, and the polyatomic anion , or . Most of the approximately 5 billion kilograms of acetic acid produced annually in industry are used in the production of acetates, which usually take the form of polymers. In nature, acetate is the most common building block for biosynthesis. Nomenclature and common formula When part of a salt, the formula of the acetate ion ...

4-methylaminorex
4-Methylaminorex (4-MAR, 4-MAX) is a stimulant drug of the 2-amino-5-aryloxazoline class that was first synthesized in 1960 by McNeil Laboratories. It is also known by its street name "U4Euh" ("Euphoria"). It is banned in many countries as a stimulant. 4-Methylaminorex has effects comparable to methamphetamine but with a longer duration. The results of animal experiments conducted with this drug suggest that it has an abuse liability similar to cocaine and amphetamine. One study found that, "stimulus properties of racemic cis, racemic trans, and all four individual optical isomers of 4-methylaminorex were examined in rats trained to discriminate 1 mg/kg of S(+)amphetamine sulfate from saline. The S(+)amphetamine stimulus generalized to all of the agents investigated". A second study in which rats trained to discriminate either 0.75 mg/kg S(+)-amphetamine or 1.5 mg/kg fenfluramine from saline generalized to aminorex as amphetamine stimulus but not to fenfluramine.
