Alpidem
Alpidem, sold under the brand name Ananxyl, is a nonbenzodiazepine anxiolytic medication which was briefly used to treat anxiety disorders but is no longer marketed. It was previously marketed in France, but was list of withdrawn drugs, discontinued due to liver toxicity. Alpidem is taken oral administration, by mouth. Side effects of alpidem include sedation, fatigue (medical), fatigue, dizziness, and headache, among others. It has much less to no impact on cognition, memory, and Psychomotor agitation, psychomotor function relative to benzodiazepines. Similarly, no rebound effect, rebound anxiety or withdrawal symptoms have been observed with alpidem. Rarely, alpidem can cause serious liver toxicity, including liver failure and death. Alpidem is a nonbenzodiazepine of the imidazopyridine family, chemical structure, structurally related to the Z-drug zolpidem, and acts as a GABAA receptor positive allosteric modulator, GABAA receptor positive allosteric modulator of the benzodia ...

Anxiolytic
An anxiolytic (; also antipanic or anti-anxiety agent) is a medication or other intervention that reduces anxiety. This effect is in contrast to anxiogenic agents which increase anxiety. Anxiolytic medications are used for the treatment of anxiety disorders and their related psychological and physical symptoms. Nature of anxiety Anxiety is a naturally-occurring emotion and response. When anxiety levels exceed the tolerability of a person, anxiety disorders may occur. People with anxiety disorders can exhibit fear responses, such as defensive behaviors, high levels of alertness, and negative emotions. Those with anxiety disorders may have concurrent psychological disorders, such as depression. Anxiety disorders are classified using six possible clinical assessments: Different types of anxiety disorders will share some general symptoms while having their own distinctive symptoms. This explains why people with different types of anxiety disorders will respond differently to diffe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Z-drug
Nonbenzodiazepines (), sometimes referred to colloquially as Z-drugs (as many of their names begin with the letter "z"), are a class of psychoactive, depressant, sedative, hypnotic, anxiolytic drugs that are benzodiazepine-like in uses, such as for treating insomnia and anxiety. Nonbenzodiazepine pharmacodynamics are similar in mechanism of action to benzodiazepine drugs, acting as GABAA receptor positive allosteric modulators of the benzodiazepine site, and therefore exhibit similar benefits, side effects, and risks. However, nonbenzodiazepines have dissimilar or entirely different chemical structures, so are unrelated to benzodiazepines on a molecular level. Background Nonbenzodiazepines have demonstrated efficacy in treating sleep disorders. There is some limited evidence that suggests that tolerance to nonbenzodiazepines is slower to develop than with benzodiazepines. However, data is limited so no conclusions can be drawn. Data is also limited into the long-term effects o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
List Of Withdrawn Drugs
Medication, Drugs or medicines may be withdrawn from commercial markets because of risks to patients, but also because of commercial reasons (e.g. lack of demand and relatively high production costs) or because it turns out that they are less effective in clinical practice than premarketing efficacy trials suggested. When risks or harms are the cause, withdrawals will usually have been prompted by unexpected adverse effects that were not detected during the early, premaketing, clinical trials, i.e. they became apparent only from postmarketing surveillance data collected from the wider community during routine use over longer periods of time. This list is not limited to drugs that were ever approved by specific jurisdictions. Some of them (lumiracoxib, rimonabant, tolrestat, ximelagatran, and zimeldine, for example) received marketing approval in Europe but had not yet been approved for marketing in the USA when adverse effects became clear and they were withdrawn from the market.

Imidazopyridine
An imidazopyridine is a nitrogen containing heterocycle that is also a class of medication, drugs that contain this same chemical substructure. In general, they are GABAA receptor, GABAA receptor receptor_agonist, agonists, however recently proton pump inhibitors, aromatase inhibitors, NSAIDs and other classes of drugs in this class have been developed as well. Despite usually being similar to them in effect, they are not chemically related to benzodiazepines. As such, GABAA-agonizing imidazopyridines, pyrazolopyrimidines, and cyclopyrrones are sometimes grouped together and referred to as "nonbenzodiazepines." Imidazopyridines include: Sedatives Anxiolytics, sedatives and hypnotics (GABAA receptor positive allosteric modulator, GABAA receptor positive allosteric modulators): * Imidazo[1,2-a]pyridines: ** Alpidem (original brand name Ananxyl)—an anxiolytic that was withdrawn from the market worldwide in 1995 due to hepatotoxicity. ** DS-1 (drug), DS-1—a GABAA receptor, GABAA ...

Anxiety
Anxiety is an emotion characterised by an unpleasant state of inner wikt:turmoil, turmoil and includes feelings of dread over Anticipation, anticipated events. Anxiety is different from fear in that fear is defined as the emotional response to a present threat, whereas anxiety is the anticipation of a future one. It is often accompanied by nervous behavior such as pacing back and forth, Somatic anxiety, somatic complaints, and Rumination (psychology), rumination. Anxiety is a feeling of uneasiness and worry, usually generalized and unfocused as an overreaction to a situation that is only subjectively seen as menacing. It is often accompanied by muscular tension, restlessness, Fatigue (medical), fatigue, inability to catch one's breath, tightness in the abdominal region, nausea, and problems in concentration. Anxiety is closely related to fear, which is a response to a real or perceived immediate threat (fight-or-flight response); anxiety involves the expectation of a future t ...

Rebound Effect
The rebound effect, or rebound phenomenon, is the emergence or re-emergence of symptoms that were either absent or controlled while taking a medication, but appear when that same medication is discontinued or reduced in dosage. In the case of re-emergence, the severity of the symptoms is often worse than pretreatment levels. Definition The rebound effect, or pharmaceutical rebound phenomenon, is the emergence or re-emergence of symptoms that were either absent or controlled while taking a medication, but appear when that same medication is discontinued or reduced in dosage. In the case of re-emergence, the severity of the symptoms is often worse than pretreatment levels. Examples Sedative hypnotics Rebound insomnia is insomnia that occurs following discontinuation of sedative substances taken to relieve primary insomnia. Regular use of these substances can cause a person to become dependent on their effects in order to fall asleep. Therefore, when a person has stopped taking the ...

Dizziness
Dizziness is an imprecise term that can refer to a sense of disorientation in space, vertigo, or lightheadedness. It can also refer to Balance disorder, disequilibrium or a non-specific feeling, such as giddiness or foolishness. Dizziness is a common medical complaint, affecting 20–30% of persons. Dizziness is broken down into four main subtypes: vertigo (~25–50%), equilibrioception#Dysfunction, disequilibrium (less than ~15%), presyncope (less than ~15%), and nonspecific dizziness (~10%). * Vertigo is the sensation of spinning or having one's surroundings spin about them. Many people find vertigo very disturbing and often report associated nausea and vomiting. * Presyncope describes lightheadedness or feeling faint; the name relates to Syncope (medicine), syncope, which is actually fainting. * equilibrioception#Dysfunction, Disequilibrium is the sensation of being off balance and is most often characterized by frequent falls in a specific direction.

Liver Failure
Liver failure is the inability of the liver to perform its normal synthetic and metabolic functions as part of normal physiology. Two forms are recognised, acute and chronic (cirrhosis). Recently, a third form of liver failure known as acute-on-chronic liver failure (ACLF) is increasingly being recognized. Acute Acute liver failure is defined as "the rapid development of hepatocellular dysfunction, specifically coagulopathy and mental status changes (encephalopathy) in a patient without known prior liver disease".:1557 The disease process is associated with the development of a coagulopathy of liver aetiology, and clinically apparent altered level of consciousness due to hepatic encephalopathy. Several important measures are immediately necessary when the patient presents for medical attention. The diagnosis of acute liver failure is based on a physical exam, laboratory findings, patient history, and past medical history to establish mental status changes, coagulopathy, ...
