Oxymorphone
Oxymorphone (sold under the brand names Numorphan and Opana among others) is a highly potent opioid analgesic indicated for treatment of severe pain. Pain relief after injection begins after about 5–10 minutes; after oral administration it begins after about 30 minutes and lasts about 3–4 hours for immediate-release tablets and 12 hours for extended-release tablets. The elimination half-life of oxymorphone is much faster intravenously, and as such, the drug is most commonly used orally. Like oxycodone, which metabolizes to oxymorphone, oxymorphone has a high abuse potential. Oxymorphone was developed in Germany in 1914. It was patented in 1955 and approved for medical use in 1959. In June 2017 the FDA asked Endo Pharmaceuticals to remove its product from the US market. This was in part due to the opioid epidemic in the US, and the fact that a 2012 reformulation failed to stop illicit injection of the drug. Endo responded by voluntarily removing Opana ER from the market ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Oxycodone
Oxycodone, sold under the brand name Roxicodone and OxyContin (which is the extended-release form) among others, is a semi-synthetic opioid used medically for the treatment of moderate to severe pain. It is highly addictive and is a commonly drug abuse, abused drug. It is usually taken oral administration, by mouth, and is available in immediate release, immediate-release and controlled release, controlled-release formulations. Onset of pain relief typically begins within fifteen minutes and lasts for up to six hours with the immediate-release formulation. In the United Kingdom, it is available by Injection (medicine), injection. Combination drug, Combination products are also available with oxycodone/paracetamol, paracetamol (acetaminophen), oxycodone/ibuprofen, ibuprofen, oxycodone/naloxone, naloxone, naltrexone, and oxycodone/aspirin, aspirin. Common side effects include euphoria, constipation, nausea, vomiting, Anorexia (symptom), loss of appetite, Somnolence, drowsiness, ...

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] |
Controlled Substances Act
The Controlled Substances Act (CSA) is the statute establishing federal government of the United States, federal drug policy of the United States, U.S. drug policy under which the manufacture, importation, possession, use, and distribution of certain substances is regulated. It was passed by the 91st United States Congress as Title II of the Comprehensive Drug Abuse Prevention and Control Act of 1970 and signed into law by President Richard Nixon. The Act also served as the national implementing legislation for the Single Convention on Narcotic Drugs. The legislation created five schedules (classifications), with varying qualifications for a substance to be included in each. Two federal agencies, the Drug Enforcement Administration (DEA) and the Food and Drug Administration (FDA), determine which substances are added to or removed from the various schedules, although the statute passed by Congress created the initial listing. Congress has sometimes scheduled other substances t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Noroxymorphone
Noroxymorphone is an opioid which is both a metabolite of oxymorphone and oxycodone and is manufactured specifically as an intermediate in the production of narcotic antagonists such as naltrexone and others. It is a potent agonist of the μ-opioid receptor, but is poorly able to cross the blood-brain-barrier into the central nervous system, and for this reason, has only minimal analgesic activity. In the United States, noroxymorphone is controlled as a Schedule II Narcotic controlled substance with an ACSCN of 9637 and in 2014 the DEA set annual aggregate manufacturing quotas of 17 500 kilogrammes for conversion and 1262.5 kg for sale. In other countries, it may be similarly controlled, controlled at a lower level, or regulated in another way.

Analgesic
An analgesic drug, also called simply an analgesic, antalgic, pain reliever, or painkiller, is any member of the group of drugs used for pain management. Analgesics are conceptually distinct from anesthetics, which temporarily reduce, and in some instances eliminate, sensation, although analgesia and anesthesia are neurophysiologically overlapping and thus various drugs have both analgesic and anesthetic effects. Analgesic choice is also determined by the type of pain: For neuropathic pain, recent research has suggested that classes of drugs that are not normally considered analgesics, such as tricyclic antidepressants and anticonvulsants may be considered as an alternative. Various analgesics, such as many NSAIDs, are available over the counter in most countries, whereas various others are prescription drugs owing to the substantial risks and high chances of overdose, misuse, and addiction in the absence of medical supervision. Etymology The word ''analgesic'' derive ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Epidural
Epidural administration (from Ancient Greek ἐπί, "upon" + '' dura mater'') is a method of medication administration in which a medicine is injected into the epidural space around the spinal cord. The epidural route is used by physicians and nurse anesthetists to administer local anesthetic agents, analgesics, diagnostic medicines such as radiocontrast agent Radiocontrast agents are substances used to enhance the visibility of internal structures in X-ray-based imaging techniques such as computed tomography (contrast CT), projectional radiography, and fluoroscopy. Radiocontrast agents are typically iod ...s, and other medicines such as glucocorticoids. Epidural administration involves the placement of a catheter into the epidural space, which may remain in place for the duration of the treatment. The technique of intentional epidural administration of medication was first described in 1921 by the Spanish Aragonese people, Aragonese military surgeon Fidel Pagés. Epidural ...

Opioid Epidemic
The opioid epidemic, also referred to as the opioid crisis, is the rapid increase in the overuse, misuse or abuse, and overdose deaths attributed either in part or in whole to the class of drugs called opiates or opioids since the 1990s. It includes the significant medical, social, psychological, demographic and economic consequences of the medical, non-medical, and recreational abuse of these medications. Opioids are a diverse class of moderate to strong painkillers, including oxycodone (commonly sold under the trade names OxyContin and Percocet), hydrocodone ( Vicodin, Norco), and fentanyl (Abstral, Actiq, Duragesic, Fentora), which is a very strong painkiller that is synthesized to resemble other opiates such as opium-derived morphine and heroin. The potency and availability of these substances, despite the potential risk of addiction and overdose, have made them popular both as medical treatments and as recreational drugs. Due to the sedative effects of opioids on the re ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hypotension
Hypotension, also known as low blood pressure, is a cardiovascular condition characterized by abnormally reduced blood pressure. Blood pressure is the force of blood pushing against the walls of the arteries as the heart pumps out blood and is indicated by two numbers, the systolic blood pressure (the top number) and the diastolic blood pressure (the bottom number), which are the maximum and minimum blood pressures within the cardiac cycle, respectively. A systolic blood pressure of less than 90 millimeters of mercury (mmHg) or diastolic of less than 60 mmHg is generally considered to be hypotension. Different numbers apply to children. However, in practice, blood pressure is considered too low only if noticeable symptoms are present. Symptoms may include dizziness, lightheadedness, confusion, feeling tired, weakness, headache, blurred vision, nausea, neck or back pain, an irregular heartbeat or feeling that the heart is skipping beats or fluttering, sweating, an ...

Bradycardia
Bradycardia, also called bradyarrhythmia, is a resting heart rate under 60 beats per minute (BPM). While bradycardia can result from various pathological processes, it is commonly a physiological response to cardiovascular conditioning or due to asymptomatic type 1 atrioventricular block. Resting heart rates of less than 50 BPM are often normal during sleep in young and healthy adults and athletes. In large population studies of adults without underlying heart disease, resting heart rates of 45–50 BPM appear to be the lower limits of normal, dependent on age and sex. Bradycardia is most likely to be discovered in the elderly, as age and underlying cardiac disease progression contribute to its development. Bradycardia may be associated with symptoms of fatigue, dyspnea, dizziness, confusion, and syncope due to reduced blood flow to the brain. The types of symptoms often depend on the etiology of the slow heart rate, classified by the anatomical location of a dysfunctio ...

Flaccidity
Flaccid paralysis is a neurological condition characterized by weakness or paralysis and reduced muscle tone without other obvious cause (e.g., trauma). This abnormal condition may be caused by disease or by trauma affecting the nerves associated with the involved muscles. For example, if the somatic nerves to a skeletal muscle are severed, then the muscle will exhibit flaccid paralysis. When muscles enter this state, they become limp and cannot contract. This condition can become fatal if it affects the respiratory muscles, posing the threat of suffocation. It also occurs in the spinal shock stage in complete transection of the spinal cord occurring in injuries such as gunshot wounds.Saladin, Kenneth S. Anatomy & Physiology: The Unity of Form and Function. McGraw-Hill. 6th Edition. 2012.

Pharmacokinetics
Pharmacokinetics (from Ancient Greek ''pharmakon'' "drug" and ''kinetikos'' "moving, putting in motion"; see chemical kinetics), sometimes abbreviated as PK, is a branch of pharmacology dedicated to describing how the body affects a specific substance after administration. The substances of interest include any chemical xenobiotic such as pharmaceutical drugs, pesticides, food additives, cosmetics, etc. It attempts to analyze chemical metabolism and to discover the fate of a chemical from the moment that it is administered up to the point at which it is completely eliminated from the body. Pharmacokinetics is based on mathematical modeling that places great emphasis on the relationship between drug plasma concentration and the time elapsed since the drug's administration. Pharmacokinetics is the study of how an organism affects the drug, whereas pharmacodynamics (PD) is the study of how the drug affects the organism. Both together influence dosing, benefit, and adverse effe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
