Hydroxyphenamate or oxyfenamate (trade name Listica) is a sedative and anxiolytic drug of the carbamate class which is no longer marketed in the US. Like other carbamate sedatives, it is chemically related to meprobamate (Miltown). It was introduced to the US market in 1961. The dosage for adults is 200 mg 3 to 4 times daily. [2]
The reaction of Propiophenone [93-55-0] (1) with cyanide gives 2-hydroxy-2-phenylbutanenitrile CID:13089766 (2). Acid hydrolysis of the nitrile to a carboxylic acid gives 2-hydroxy-2-phenylbutanoic acid [35468-69-0] (3). The reduction by hydride of the acid to the alcohol gives 2-phenyl-1,2-butanediol, CID:13260818 (4).
For the final step in the synthesis, treatment with Ethyl chloroformate followed by addition of aqueous ammonia gave the carbamate, and hence hydroxyphenamate (5).
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.
Ethchlorvynol is a GABA-ergic sedative and hypnotic/soporific medication first developed by Pfizer in the 1950s. In the United States it was sold by Abbott Laboratories under the trade name Placidyl. Placidyl was available in 200 mg, 500 mg, and 750 mg strength gel filled capsules. While the 500 mg and 750 mg strength capsules were for use in reducing sleep latency, the 200 mg strength capsules were intended to be used to re-induce sleep in case of early awakening. Abbott discontinued production in 1999, due to it being replaced by the benzodiazepine family and its widespread abuse, after which Placidyl was available for about a year in the United States. Although, theoretically, ethchlorvynol could be manufactured for sale in the United States by another pharmaceutical company, no pharmaceutical company has chosen to do so. Individuals with a valid prescription for the substance may legally transport a reasonable amount of ethclorvynol with them into the United States.
Piperonal, also known as heliotropin, is an organic compound which is commonly found in fragrances and flavors. The molecule is structurally related to other aromatic aldehydes such as benzaldehyde and vanillin.
Phendimetrazine is a stimulant drug of the morpholine chemical class used as an appetite suppressant.
Secobarbital is a short-acting barbiturate derivative drug that was patented in 1934 in the United States. It possesses anaesthetic, anticonvulsant, anxiolytic, sedative, and hypnotic properties. In the United Kingdom, it was known as quinalbarbitone. It is the most frequently used drug in physician-assisted suicide within the United States. Secobarbital is considered to be an obsolete sedative-hypnotic, and as a result, it has largely been replaced by the benzodiazepine family. Seconal was widely abused, known on the street as "red devils" or "reds".
Nomifensine (Merital, Alival) is a norepinephrine-dopamine reuptake inhibitor, i.e. a drug that increases the amount of synaptic norepinephrine and dopamine available to receptors by blocking the dopamine and norepinephrine reuptake transporters. This is a mechanism of action shared by some recreational drugs like cocaine and the medication tametraline (see DRI). Research showed that the (S)-isomer is responsible for activity.
Beclamide is a drug that possesses anticonvulsant activity. It is no longer used.
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.
Oxybuprocaine (INN), also known as benoxinate or BNX, is an ester-type local anesthetic, which is used especially in ophthalmology and otolaryngology. Oxybuprocaine is sold by Novartis under the brand names Novesine or Novesin.
Vinylbital, also known as butylvinal, is a sedative hypnotic drug which is a barbiturate derivative. It was developed by Aktiebolaget Pharmacia in the 1950s.
Mesoridazine(Serentil) is a piperidine neuroleptic drug belonging to the class of drugs called phenothiazines, used in the treatment of schizophrenia. It is a metabolite of thioridazine. The drug's name is derived from the methylsulfoxy and piperidine functional groups in its chemical structure.
Ethinamate is a short-acting carbamate-derivative sedative-hypnotic medication used to treat insomnia. Regular use leads to drug tolerance, and it is usually not effective for more than 7 days. Prolonged use can lead to dependence.
Methyprylon, or Noludar, is a sedative of the piperidinedione derivative family first developed by Hoffmann-La Roche. This medicine was used for treating insomnia, but is now rarely used as it has been replaced by newer drugs with fewer side effects, such as benzodiazepines.
Promazine, is used as a short-term add-on treatment for psychomotor agitation. Its approved uses in people is limited, but is used as a tranquilizer in veterinary medicine. It has weak antipsychotic effects but is generally not used to treat psychoses.
Triclofos is a sedative drug used rarely for treating insomnia.
Methylpentynol is a tertiary hexynol with hypnotic/sedative and anticonvulsant effects and an exceptionally low therapeutic index. It was discovered by Bayer in 1913 and was used shortly thereafter for the treatment of insomnia, but its use was quickly phased out in response to newer drugs with far more favorable safety profiles.
Chloralodol (Chlorhexadol) is a hypnotic/sedative. It is a Schedule III drug in the USA; however, it is not currently marketed in the United States so it is no longer prescribed.
Hydroxydione, as hydroxydione sodium succinate, also known as 21-Hydroxy-5β-pregnane-3,20-dione, is a neuroactive steroid which was formerly used as a general anesthetic, but was discontinued due to incidence of thrombophlebitis in patients. It was introduced in 1957, and was the first neuroactive steroid general anesthetic to be introduced for clinical use, an event which was shortly preceded by the observation in 1954 of the sedative properties of progesterone in mice.
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.
Homofenazine is an antipsychotic drug of the phenothiazines class. It was synthesized by Wilhelm Schuler and colleagues at Degussa. In 1966, it was released in Belgium under the brand name Pasaden. At some point, it was quietly discontinued and is no longer marketed.
