Lunesta
Eszopiclone, sold under the brand-name Lunesta among others such as Night Calm in Egypt, is a medication used in the treatment of insomnia. Evidence supports slight to moderate benefit up to six months. It is taken orally. Common side effects include headache, dry mouth, nausea, and dizziness. Severe side effects may include suicidal thoughts, unhealthy non-medical use, hallucinations, and angioedema. Greater care is recommended in those with liver problems and older people. Rapid decreasing of the dose may result in withdrawal. Eszopiclone is classified as a nonbenzodiazepine sedative hypnotic and as a cyclopyrrolone. It is the S-stereoisomer of zopiclone. It works by interacting with the GABA receptors. Approved for medical use in the United States in 2004, eszopiclone is available as generic medication. In 2020, it was the 232nd most commonly prescribed medication in the United States, with more than 1million prescriptions. Eszopiclone is not sold in the European Union, as o ...

Nonbenzodiazepine
Nonbenzodiazepines (), sometimes referred to colloquially as Z-drugs (as many of their names begin with the letter "z"), are a class of psychoactive drugs that are very benzodiazepine-like in nature. They are used in the treatment of sleep problems, and for their anxiolytic effects. Nonbenzodiazepine pharmacodynamics are almost entirely the same as benzodiazepine drugs and therefore exhibit similar benefits, side-effects, and risks. However, nonbenzodiazepines have dissimilar or entirely different chemical structures and are therefore unrelated to benzodiazepines on a molecular level. Classes Currently, the major chemical classes of nonbenzodiazepines are: Imidazopyridines * Alpidem * Necopidem * Saripidem * Zolpidem (Ambien, Ambien CR, Intermezzo, Zolpimist, Edluar, Ivadal, Sanval, Stilnox, etc.) Pyrazolopyrimidines * Divaplon * Fasiplon * Indiplon * Lorediplon * Ocinaplon * Panadiplon * Taniplon * Zaleplon (Sonata, Starnoc, Andante) Cyclopyrrolones * Eszopiclone (Lunesta, V ...

Zopiclone
Zopiclone, sold under the brand name Imovane among others, is a nonbenzodiazepine used to treat insomnia, difficulty sleeping. Zopiclone is molecularly distinct from benzodiazepine drugs and is classed as a cyclopyrrolone. However, zopiclone increases the normal transmission of the neurotransmitter gamma-aminobutyric acid (GABA) in the central nervous system, via modulating GABAA receptor, GABAA receptors similarly to the way benzodiazepine drugs do. Zopiclone is a sedative. It works by causing a depression or tranquilization of the central nervous system. After prolonged use, the body can become accustomed to the effects of zopiclone. When the dose is then reduced or the drug is abruptly stopped, withdrawal symptoms may result. These can include a range of symptoms similar to those of benzodiazepine withdrawal. Although withdrawal symptoms from therapeutic doses of zopiclone and its isomers (i.e., eszopiclone) do not typically present with convulsions and are therefore not cons ...

Cyclopyrrolone
Cyclopyrrolones are a family of hypnotic and anxiolytic nonbenzodiazepine drugs with similar pharmacological profiles to the benzodiazepine derivatives. Although cyclopyrrolones are chemically unrelated to benzodiazepines, they function via the benzodiazepine receptor of neurotransmitter GABA. The best-known cyclopyrrolone derivatives are zopiclone (Imovane) and its active single-enantiomer component, eszopiclone (Lunesta), which are used to treat insomnia, and have a known potential for abuse. Other cyclopyrrolones include: * Pagoclone – anxiolytic * Pazinaclone – anxiolytic * Suproclone – anxiolytic * Suriclone Suriclone (Suril) is a sedative and anxiolytic drug in the cyclopyrrolone family of drugs. Other cyclopyrrolone drugs include zopiclone and pagoclone. Suriclone has a very similar pharmacological profile to the benzodiazepine family of drugs inc ... – anxiolytic References Chemical classes of psychoactive drugs {{heterocyclic-stub ...

Anterograde Amnesia
In neurology, anterograde amnesia is the inability to create new memories after the event that caused amnesia, leading to a partial or complete inability to recall the recent past, while long-term memories from before the event remain intact. This is in contrast to retrograde amnesia, where memories created prior to the event are lost while new memories can still be created. Both can occur together in the same patient. To a large degree, anterograde amnesia remains a mysterious ailment because the precise mechanism of storing memories is not yet well understood, although it is known that the regions of the brain involved are certain sites in the temporal cortex, especially in the hippocampus and nearby subcortical regions. Signs and symptoms People with anterograde amnesic syndromes may present with widely varying degrees of forgetfulness. Some with severe cases have a combined form of anterograde and retrograde amnesia, sometimes called global amnesia. In the case of drug-i ...

Tablet (pharmacy)
A tablet (also known as a pill) is a pharmaceutical oral dosage form (''oral solid dosage'', or OSD) or solid unit dosage form. Tablets may be defined as the solid unit dosage form of medicament or medicaments with suitable excipients. It comprises a mixture of active substances and excipients, usually in powder form, pressed or compacted from a powder into a solid dose. Tablets are prepared either by molding or by compression. The excipients can include diluents, binders or granulating agents, glidants (flow aids) and lubricants to ensure efficient tabletting; disintegrants to promote tablet break-up in the digestive tract; sweeteners or flavours to enhance taste; and pigments to make the tablets visually attractive or aid in visual identification of an unknown tablet. A polymer coating is often applied to make the tablet smoother and easier to swallow, to control the release rate of the active ingredient, to make it more resistant to the environment (extending its shelf li ...

Zaleplon
Zaleplon, sold under the brand names Sonata among others, is a sedative-hypnotic, used to treat insomnia. It is a nonbenzodiazepine hypnotic from the pyrazolopyrimidine class. It is manufactured by King Pharmaceuticals and Gedeon Richter Plc. It has been discontinued in Canada but can be manufactured if a prescription is brought to a compounding pharmacy. It was prescribed rarely in the United Kingdom, with zopiclone being the preferred Z-drug by the National Health Service (NHS) and is now unavailable. Medical uses Zaleplon is slightly effective in insomnia, primarily characterized by difficulty falling asleep. Zaleplon significantly reduces the time required to fall asleep by improving sleep latency and may therefore facilitate sleep induction rather than sleep maintenance. Due to its ultrashort elimination half-life, zaleplon may not be effective in reducing premature awakenings; however, it may be administered to alleviate middle-of-the-night awakenings. However, zaleplo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Milligram
The kilogram (also kilogramme) is the unit of mass in the International System of Units (SI), having the unit symbol kg. It is a widely used measure in science, engineering and commerce worldwide, and is often simply called a kilo colloquially. It means 'one thousand grams'. The kilogram is defined in terms of the second and the metre, both of which are based on fundamental physical constants. This allows a properly equipped metrology laboratory to calibrate a mass measurement instrument such as a Kibble balance as the primary standard to determine an exact kilogram mass. The kilogram was originally defined in 1795 as the mass of one litre of water. The current definition of a kilogram agrees with this original definition to within 30 parts per million. In 1799, the platinum ''Kilogramme des Archives'' replaced it as the standard of mass. In 1889, a cylinder of platinum-iridium, the International Prototype of the Kilogram (IPK), became the standard of the unit of mass for t ...

American Geriatrics Society
The American Geriatrics Society (AGS) is a non-profit professional society founded on June 11, 1942, for health care professionals practicing geriatric medicine. Among the founding physicians were Dr. Ignatz Leo Nascher, who coined the term "geriatrics", Dr. Malford W. Thewlis, who was named the first executive secretary of the Society, and Dr. Lucien Stark who was appointed the first AGS president. History In 1999 the Society established the AGS Health in Aging Foundation (HiAF) to further advance aging research, educate the public and legislators about healthcare for older people, and encourage the public to advocate for quality geriatrics care. The Association of Directors of Geriatrics Academic Programs (ADGAP), established in 1990, became a supporting organization of the Society in 2002. The AGS now counts nearly 6,000 geriatrics healthcare providers including geriatricians, geriatrics nurse practitioners, physician assistants, pharmacists, and social workers as members. ...

Melatonin Receptor Agonists
Melatonin receptor agonists are analogues of melatonin that bind to and activate the melatonin receptor. Agonists of the melatonin receptor have a number of therapeutic applications including treatment of sleep disorders and depression. The discovery and development of melatonin receptor agonists was motivated by the need for more potent analogues than melatonin, with better pharmacokinetics and longer half-lives. Melatonin receptor agonists were developed with the melatonin structure as a model. The melatonin receptors are G protein-coupled receptors and are expressed in various tissues of the body. There are two subtypes of the receptor in humans, melatonin receptor 1 (MT1) and melatonin receptor 2 (MT2). Melatonin and melatonin receptor agonists, on market or in clinical trials, all bind to and activate both receptor types. The binding of the agonists to the receptors has been investigated since 1986, yet is still not fully understood. When melatonin receptor agonists bind to a ...

Zolpidem
Zolpidem, sold under the brand name Ambien, among others, is a medication primarily used for the short-term treatment of sleeping problems. Guidelines recommend that it be used only after cognitive behavioral therapy for insomnia and behavioral changes, such as sleep hygiene, have been tried. It decreases the time to sleep onset by about fifteen minutes and at larger doses helps people stay asleep longer. It is taken by mouth and is available in conventional tablets, sublingual tablets, or oral spray. Common side effects include daytime sleepiness, headache, nausea, and diarrhea. More severe side effects include memory problems and hallucinations. The previously recommended dose was decreased in 2013, by the US Food and Drug Administration (FDA), to the immediate-release 10mg for men, and 5mg for women, in an attempt to reduce next-day somnolence. Newer extended-release formulations include the 6.25mg for women, and 12.5mg or 6.25mg for men, which also cause next-day somnolenc ...

European Medicines Agency
The European Medicines Agency (EMA) is an agency of the European Union (EU) in charge of the evaluation and supervision of medicinal products. Prior to 2004, it was known as the European Agency for the Evaluation of Medicinal Products or European Medicines Evaluation Agency (EMEA).Set up by EC Regulation No. 2309/93 as the European Agency for the Evaluation of Medicinal Products, and renamed by EC Regulation No. 726/2004 to the European Medicines Agency, it had the acronym EMEA until December 2009. The European Medicines Agency does not call itself EMA either – it has no official acronym but may reconsider if EMA becomes commonly accepted (secommunication on new visual identity an). The EMA was set up in 1995, with funding from the European Union and the pharmaceutical industry, as well as indirect subsidy from member states, its stated intention to harmonise (but not replace) the work of existing national medicine regulatory bodies. The hope was that this plan would not onl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
