Ohmefentanyl
Ohmefentanyl (also known as β-hydroxy-3-methylfentanyl, OMF and RTI-4614-4) is an extremely potent opioid analgesic drug which selectively binds to the µ-opioid receptor. There are eight possible stereoisomers of ohmefentanyl. These stereoisomers are among the most potent μ-opioid receptor agonists known, comparable to super-potent opioids such as carfentanil and etorphine which are only legally used for tranquilizing large animals such as elephants in veterinary medicine. In mouse studies, the most active stereoisomer, 3R,4S,βS-ohmefentanyl, was 28 times more powerful as a painkiller than fentanyl, the chemical from which it is derived, and 6300 times more powerful than morphine. Ohmefentanyl has three stereogenic centers and eight stereoisomers, which are named F9201–F9208. Researchers are studying the different pharmaceutical properties of these isomers. The 4″-fluoro analogue (i.e., substituted on the phenethyl ring) of the 3R,4S,βS isomer of ohmefentanyl is o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

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 use of op ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

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 as well. 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.

Respiratory Depression
Hypoventilation (also known as respiratory depression) occurs when ventilation is inadequate (''hypo'' meaning "below") to perform needed respiratory gas exchange. By definition it causes an increased concentration of carbon dioxide (hypercapnia) and respiratory acidosis. Hypoventilation is not synonymous with respiratory arrest, in which breathing ceases entirely and death occurs within minutes due to hypoxia and leads rapidly into complete anoxia, although both are medical emergencies. Hypoventilation can be considered a precursor to hypoxia and its lethality is attributed to hypoxia with carbon dioxide toxicity. Causes Hypoventilation may be caused by: *A medical condition such as stroke affecting the brainstem *Voluntary breath-holding or underbreathing, for example, hypoventilation training or the Buteyko method. *Medication or drugs, typically when taken in accidental or intentional overdose. Opioids and benzodiazepines in particular are known to cause respiratory de ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Piperidines
Piperidine is an organic compound with the molecular formula (CH2)5NH. This heterocyclic amine consists of a six-membered ring containing five methylene bridges (–CH2–) and one amine bridge (–NH–). It is a colorless liquid with an odor described as objectionable, and typical of amines. The name comes from the genus name '' Piper'', which is the Latin word for pepper. Although piperidine is a common organic compound, it is best known as a representative structure element within many pharmaceuticals and alkaloids, such as natural-occurring solenopsins. Production Piperidine was first reported in 1850 by the Scottish chemist Thomas Anderson and again, independently, in 1852 by the French chemist Auguste Cahours, who named it. Both of them obtained piperidine by reacting piperine with nitric acid. Industrially, piperidine is produced by the hydrogenation of pyridine, usually over a molybdenum disulfide catalyst: : C5H5N + 3 H2 → C5H10NH Pyridine can also be redu ...

Ohmecarfentanil
Ohmecarfentanil (RTI-4614-38), also known as Ohlofentanil, is a mu opioid receptor agonist from the class of fentanyl analogues which was found to be 30,000 times more potent than morphine in the rhesus monkey single dose suppression test. This makes ohmecarfentanil, along with some closely related analogues, among the most potent opioid agonists known at this time, even surpassing lofentanil and ohmefentanyl Ohmefentanyl (also known as β-hydroxy-3-methylfentanyl, OMF and RTI-4614-4) is an extremely potent opioid analgesic drug which selectively binds to the µ-opioid receptor.

Carfentanil
Carfentanil or carfentanyl, sold under the brand name Wildnil, is a very potent opioid analgesic which is used in veterinary medicine to anesthetize large animals such as elephants and rhinoceroses. It is typically administered in this context by tranquilizer dart. Carfentanil has also been used in humans for imaging of 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 naltrexone, though higher or multiple doses than usual may be necessary compa ...

Fentanyl
Fentanyl, also spelled fentanil, is a very potent synthetic opioid used as a pain medication. Together with other drugs, fentanyl is used for anesthesia. It is also used illicitly as a recreational drug, sometimes mixed with heroin, cocaine, benzodiazepines or methamphetamine, among others. Its potentially deadly overdose effects can be neutralized by naloxone. Fentanyl is commonly used to create counterfeit pills disguised as OxyContin, Xanax, Adderall, among others. It has a rapid onset and its effects generally last under two hours. Medically, it is used by injection, nasal spray, or skin patch, or absorbed through the cheek as a lozenge or tablet. Common adverse effects of fentanyl include nausea, vomiting, constipation, itching, sedation, confusion, and injuries related to poor coordination. Serious adverse effects may include respiratory depression, hallucinations, serotonin syndrome, low blood pressure, or development of an opioid use disorder. Fentan ...
