Aprobarbital (or aprobarbitone), sold as Oramon, Somnifaine, and Allonal, is a barbiturate derivative invented in the 1920s by Ernst Preiswerk. It has sedative, hypnotic and anticonvulsant properties, and was used primarily for the treatment of insomnia. [2] Aprobarbital was never as widely used as more common barbiturate derivatives such as phenobarbital and is now rarely prescribed as it has been replaced by newer drugs with a better safety margin.
Glutethimide is a hypnotic sedative that was introduced by Ciba in 1954 as a safe alternative to barbiturates to treat insomnia. Before long, however, it had become clear that glutethimide was just as likely to cause addiction and caused similar withdrawal symptoms. Doriden was the brand-name version. Current production levels in the United States point to its use only in small-scale research. Manufacturing of the drug was discontinued in the US in 1993 and discontinued in several eastern European countries in 2006.
Alfentanil is a potent but short-acting synthetic opioid analgesic drug, used for anaesthesia in surgery. It is an analogue of fentanyl with around one-fourth to one-tenth the potency, one-third the duration of action, and an onset of action four times faster than that of fentanyl. Alfentanil has a pKa of approximately 6.5, which leads to a very high proportion of the drug being uncharged at physiologic pH, a characteristic responsible for its rapid onset. It is an agonist at mu opioid receptors.
Flurazepam is a drug which is a benzodiazepine derivative. It possesses anxiolytic, anticonvulsant, hypnotic, sedative and skeletal muscle relaxant properties. It produces a metabolite with a long half-life, which may stay in the bloodstream for days. Flurazepam was patented in 1968 and came into medical use the same year. Flurazepam, developed by Roche Pharmaceuticals, was one of the first benzodiazepine hypnotic medications to be marketed.
Amobarbital is a drug that is a barbiturate derivative. It has sedative-hypnotic properties. It is a white crystalline powder with no odor and a slightly bitter taste. It was first synthesized in Germany in 1923. It is considered a short to intermediate acting barbiturate. If amobarbital is taken for extended periods of time, physiological and psychological dependence can develop. Amobarbital withdrawal mimics delirium tremens and may be life-threatening. Amobarbital was manufactured by Eli Lilly and Company in the US under the brand name Amytal in bright blue bullet shaped capsules or pink tablets containing 50, 100, or 200 milligrams of the drug. The drug was also manufactured generically. Amobarbital was widely misused, known as "Blue Heavens" on the street. Amytal, as well as Tuinal, a combination drug containing equal quantities of secobarbital and amobarbital, were both manufactured by Eli Lilly until the late-1990s. However, as the popularity of benzodiazepines increased, prescriptions for these medications became increasingly rare beginning in the mid to late-1980s.
Clomethiazole is a sedative and hypnotic originally developed by Hoffmann-La Roche in the 1930s. The drug is used in treating and preventing symptoms of acute alcohol withdrawal.
Barbital, marketed under the brand names Veronal for the pure acid and Medinal for the sodium salt, was the first commercially available barbiturate. It was used as a sleeping aid (hypnotic) from 1903 until the mid-1950s. The chemical names for barbital are diethylmalonyl urea or diethylbarbituric acid; hence, the sodium salt is known also as sodium diethylbarbiturate.
Nordazepam is a 1,4-benzodiazepine derivative. Like other benzodiazepine derivatives, it has amnesic, anticonvulsant, anxiolytic, muscle relaxant, and sedative properties. However, it is used primarily in the treatment of anxiety disorders. It is an active metabolite of diazepam, chlordiazepoxide, clorazepate, prazepam, pinazepam, and medazepam.
Methylphenobarbital (INN), also known as mephobarbital and mephobarbitone (BAN), marketed under brand names such as Mebaral, Mephyltaletten, Phemiton, and Prominal, is a drug which is a barbiturate derivative and is used primarily as an anticonvulsant, but also as a sedative and anxiolytic. It is the N-methylated analogue of phenobarbital and has similar indications, therapeutic value, and tolerability.
Phenprobamate is a centrally acting skeletal muscle relaxant, with additional sedative and anticonvulsant effects. Overdose is similar to barbiturates. Its mechanism of action is probably similar to meprobamate. Phenprobamate has been used in humans as an anxiolytic, and is still sometimes used in general anesthesia and for treating muscle cramps and spasticity. Phenprobamate is still used in some European countries, but it has generally been replaced by newer drugs. Phenprobamate is metabolized by oxidative degradation of the carbamate group and ortho-hydroxylation of the benzene ring, and is eliminated in urine by the kidneys.
Vinylbital, also known as butylvinal, is a sedative hypnotic drug which is a barbiturate derivative. It was developed by Aktiebolaget Pharmacia in the 1950s.
Cyclobarbital, also known as cyclobarbitol or cyclobarbitone, is a barbiturate derivative. It was available in Russia as a fixed-dose combination with diazepam for the treatment of insomnia but was discontinued in 2019.
Allobarbital, also known as allobarbitone and branded as Dial, Cibalgine, or Dial-Ciba, is a barbiturate derivative invented in 1912 by Ernst Preiswerk and Ernst Grether working for CIBA. It was used primarily as an anticonvulsant although it has now largely been replaced by newer drugs with improved safety profiles. Other uses for allobarbital included as an adjutant to boost the activity of analgesic drugs, and use in the treatment of insomnia and anxiety.
Acetyldihydrocodeine is an opiate derivative discovered in Germany in 1914 and was used as a cough suppressant and analgesic. It is not commonly used, but has activity similar to other opiates. Acetyldihydrocodeine is a very close relative derivative of thebacon, where only the 6-7 bond is unsaturated. Acetyldihydrocodeine can be described as the 6-acetyl derivative of dihydrocodeine and is metabolised in the liver by demethylation and deacetylation to produce dihydromorphine.
Thiamylal (Surital) is a barbiturate derivative invented in the 1950s. It has sedative, anticonvulsant, and hypnotic effects, and is used as a strong but short acting sedative. Thiamylal is still in current use, primarily for induction in surgical anaesthesia or as an anticonvulsant to counteract side effects from other anaesthetics. It is the thiobarbiturate analogue of secobarbital.
Allylprodine is an opioid analgesic that is an analog of prodine. It was discovered by Hoffman-La Roche in 1957 during research into the related drug pethidine. Derivatives were tested to prove the theory that phenolic and non-phenolic opioids bind at different sites of the opiate receptor.
Benzethidine is a 4-phenylpiperidine derivative that is related to the clinically used opioid analgesic drug pethidine.
Alphamethadol (INN), or α-methadol, also known as alfametadol, is a synthetic opioid analgesic. It is an isomer of dimepheptanol (methadol), the other being betamethadol (β-methadol). Alphamethadol is composed of two isomers itself, L-α-methadol, and D-α-methadol. The former compound, L-α-methadol, is an important active metabolite of levacetylmethadol (LAAM), an opioid substitute drug that is used clinically. Both of alphamethadol's isomers bind to and activate the μ-opioid receptor and are active as opioid analgesics, similarly to those of alphacetylmethadol (α-acetylmethadol).
Hydromorphinol, is an opiate analogue that is a derivative of morphine, where the 14-position has been hydroxylated and the 7,8- double bond saturated. It has similar effects to morphine such as sedation, analgesia and respiratory depression, but is twice as potent as morphine and has a steeper dose-response curve and longer half-life. It is used in medicine as the bitartrate salt and hydrochloride
Phenaglycodol is a drug described as a tranquilizer or sedative which has anxiolytic and anticonvulsant properties. It is related pharmacologically to meprobamate, though it is not a carbamate.
Etodroxizine (INN) is a first-generation antihistamine of the diphenylmethylpiperazine group which is used as a sedative/hypnotic drug in Europe and South Africa.
