Necopidem
Necopidem is a drug in the imidazopyridine family, which is related to the better known drugs zolpidem and alpidem. It is therefore considered a nonbenzodiazepine and as such may have sedative and 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 anxie ... effects, given its structural similarity to other nonbenzodiazepine hypnotics.

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allosteric modulators): * Imidazo[1,2-a]pyridines: ** Alpidem (original brand name Ananxyl)—an anxiolytic that was withdrawn from the market worldwide in 1995 due to hepatotoxicity.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 ...

Nonbenzodiazepine
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 modulator, GABAA receptor positive allosteric modulators of the benzodiazepine receptor, 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 drug tolerance, tolerance to nonbenzodiazepines is slower to develop than with benzodiazepines. However, data is limit ...

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 after 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 as conventional tablets, extended-release tablets, or sublingual tablets. Common side effects include daytime sleepiness, headache, nausea, and diarrhea. More severe side effects include memory problems and hallucinations. While flumazenil, a GABAA receptor antagonist, can reverse zolpidem's effects, usually supportive care is all that is recommended in overdose. Zolpidem is a nonbenzodiazepine, or Z-drug, which acts as a sedative and hypnotic as a positive allosteric modulator at the GABAA receptor. It is an imidazopyrid ...

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 ...

Sedative
A sedative or tranquilliser is a substance that induces sedation by reducing irritability or Psychomotor agitation, excitement. They are central nervous system (CNS) Depressant, depressants and interact with brain activity, causing its deceleration. Various kinds of sedatives can be distinguished, but the majority of them affect the neurotransmitter Gamma-Aminobutyric acid, gamma-aminobutyric acid (GABA). Most sedatives produce relaxing effects by increasing GABA activity. This group is related to hypnotics. The term ''sedative'' describes drugs that serve to calm or Anxiolytic, relieve anxiety, whereas the term ''hypnotic'' describes drugs whose main purpose is to initiate, sustain, or lengthen sleep. Because these two functions frequently overlap, and because drugs in this class generally produce dose-dependent effects (ranging from anxiolysis to loss of consciousness), they are often referred to collectively as ''sedative–hypnotic'' drugs. Terminology There is some overlap ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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] |
GABAA Receptor Positive Allosteric Modulators
In pharmacology, GABAA receptor positive allosteric modulators, also known as GABAkines or GABAA receptor potentiators, are positive allosteric modulator (PAM) molecules that increase the activity of the GABAA receptor, GABAA receptor protein in the vertebrate central nervous system. GABA is a major inhibitory neurotransmitter in the central nervous system. Upon binding, it Agonist, triggers the GABAA receptor to open its GABAA receptor#Structure and function, chloride channel to allow Chloride, chloride ions into the neuron, making the cell Hyperpolarization (biology), hyperpolarized and less likely to Action potential, fire. GABAA PAMs increase the effect of GABA by making the channel open more frequently or for longer periods. However, they have no effect if GABA or another agonist is not present. Unlike GABA receptor agonist, GABAA receptor agonists, GABAA PAMs do not bind at the same active site as the γ-aminobutyric acid (GABA) neurotransmitter molecule: they affect the r ...
