Nortetrazepam [1] is a drug which is a benzodiazepine derivative. [2] [3] It is one of the major metabolites of tetrazepam. [4]
Benzodiazepines, sometimes called "benzos", are a class of psychoactive drugs whose core chemical structure is the fusion of a benzene ring and a diazepine ring. As depressants—drugs which lower brain activity—they are prescribed to treat conditions such as anxiety, insomnia, and seizures. The first benzodiazepine, chlordiazepoxide (Librium), was discovered accidentally by Leo Sternbach in 1955 and was made available in 1960 by Hoffmann–La Roche, which soon followed with diazepam (Valium) in 1963. By 1977, benzodiazepines were the most prescribed medications globally; the introduction of selective serotonin reuptake inhibitors (SSRIs), among other factors, decreased rates of prescription, but they remain frequently used worldwide.
Flunitrazepam, also known as Rohypnol among other names, is a benzodiazepine used to treat severe insomnia and assist with anesthesia. As with other hypnotics, flunitrazepam has been advised to be prescribed only for short-term use or by those with chronic insomnia on an occasional basis.
Diazepam, first marketed as Valium, is a medicine of the benzodiazepine family that acts as an anxiolytic. It is commonly used to treat a range of conditions, including anxiety, seizures, alcohol withdrawal syndrome, benzodiazepine withdrawal syndrome, muscle spasms, insomnia, and restless legs syndrome. It may also be used to cause memory loss during certain medical procedures. It can be taken by mouth, inserted into the rectum, injected into muscle, injected into a vein or used as a nasal spray. When given into a vein, effects begin in one to five minutes and last up to an hour. By mouth, effects begin after 15 to 60 minutes.
Temazepam is a medication used to treat insomnia. Such use should generally be for less than ten days. It is taken by mouth. Effects generally begin within an hour and last for up to eight hours.
Alprazolam, sold under the brand name Xanax, among others, is a fast-acting tranquilizer of medium duration in the triazolobenzodiazepine (TBZD) class, which are benzodiazepines (BZDs) fused with a triazole ring. It is most commonly used in short-term management of anxiety disorders, specifically panic disorder or generalized anxiety disorder (GAD). Other uses include the treatment of chemotherapy-induced nausea, together with other treatments. GAD improvement occurs generally within a week. Alprazolam is generally taken by mouth.
Lorazepam, sold under the brand name Ativan among others, is a benzodiazepine medication. It is used to treat anxiety disorders, trouble sleeping, severe agitation, active seizures including status epilepticus, alcohol withdrawal, and chemotherapy-induced nausea and vomiting. It is also used during surgery to interfere with memory formation and to sedate those who are being mechanically ventilated. It is also used, along with other treatments, for acute coronary syndrome due to cocaine use. It can be given by mouth or as an injection into a muscle or vein. When given by injection onset of effects is between one and thirty minutes and effects last for up to a day.
Midazolam, sold under the brand name Versed, among others, is a benzodiazepine medication used for anesthesia, procedural sedation, trouble sleeping, and severe agitation. It works by inducing sleepiness, decreasing anxiety, and causing a loss of ability to create new memories. It is important to note that this drug does not cause an individual to become unconscious, merely be sedated. It is also useful for the treatment of seizures. Midazolam can be given by mouth, intravenously, by injection into a muscle, by spraying into the nose, or through the cheek. When given intravenously, it typically begins working within five minutes; when injected into a muscle, it can take fifteen minutes to begin working. Effects last between one and six hours.
Clonazepam, sold under the brand Klonopin among others, is a medication used to prevent and treat seizures, panic disorder, anxiety, and the movement disorder known as akathisia. It is a tranquilizer of the benzodiazepine class. It is typically taken by mouth. Effects begin within one hour and last between six and twelve hours.
Oxazepam is a short-to-intermediate-acting benzodiazepine. Oxazepam is used for the treatment of anxiety and insomnia and in the control of symptoms of alcohol withdrawal syndrome.
Clobazam, sold under the brand names Frisium, Onfi and others, is a benzodiazepine class medication that was patented in 1968. Clobazam was first synthesized in 1966 and first published in 1969. Clobazam was originally marketed as an anxioselective anxiolytic since 1970, and an anticonvulsant since 1984. The primary drug-development goal was to provide greater anxiolytic, anti-obsessive efficacy with fewer benzodiazepine-related side effects.
Tetrazepam is a benzodiazepine derivative with anticonvulsant, anxiolytic, muscle relaxant and slightly hypnotic properties. It was formerly used mainly in Austria, France, Belgium, Germany and Spain to treat muscle spasm, anxiety disorders such as panic attacks, or more rarely to treat depression, premenstrual syndrome or agoraphobia. Tetrazepam has relatively little sedative effect at low doses while still producing useful muscle relaxation and anxiety relief. The Co-ordination Group for Mutual Recognition and Decentralised Procedures-Human endorsed the Pharmacovigilance Risk Assessment Committee (PRAC) recommendation to suspend the marketing authorisations of tetrazepam-containing medicines across the European Union (EU) in April 2013. The European Commission has confirmed the suspension of the marketing authorisations for Tetrazepam in Europe because of cutaneous toxicity, effective from the 1 August 2013.
Chlordiazepoxide, trade name Librium among others, is a sedative and hypnotic medication of the benzodiazepine class; it is used to treat anxiety, insomnia and symptoms of withdrawal from alcohol and other drugs.
Menitrazepam is a drug which is a benzodiazepine derivative. It is similar in structure to tetrazepam and nimetazepam, with the 7-chloro group of tetrazepam replaced by nitro. It is a hypnotic agent used in the treatment of insomnia, and therefore has strong sedative, anticonvulsant, muscle relaxant, and anxiolytic actions like those of other hypnotic benzodiazepines. Menitrazepam is a good oral hypnotic agent, however, delay in the time for peak plasma levels to reach their maximum brings into question the benefit of menitrazepam for the treatment of insomnia when compared to other hypnotics. Typically, the sleep inducing properties of hypnotics occur within 0.5 hours. In some cases, as with temazepam and nitrazepam, strong hypnotic effects can be felt 15 to 20 minutes after oral ingestion.
Proflazepam (Ro10-3580) is a drug which is a benzodiazepine derivative.
Nitrazepate (Lorzem) is a drug which is a benzodiazepine derivative and has anxiolytic properties. It is normally produced as its potassium salt, potassium nitrazepate.
Ethyl dirazepate is a drug which is a benzodiazepine derivative which was developed by Sanofi Winthrop. It has anxiolytic and hypnotic and possibly other characteristic benzodiazepine properties.
Demoxepam is a drug which is a benzodiazepine derivative. It is a metabolite of chlordiazepoxide and has anticonvulsant properties and presumably other characteristic benzodiazepine properties.
Motrazepam (Ro06-9098) is a drug which is a benzodiazepine derivative.
Tuclazepam is a drug which is a benzodiazepine derivative.
Tolufazepam is a drug that is a benzodiazepine derivative. Studies have shown tolufazepam to have anticonvulsant and anxiolytic activity in animal subjects, including convulsions elicited by pentylenetetrazol.
