Ketazolam (marketed under the brand namesAnseren,Ansieten,Ansietil,Marcen,Sedatival,Sedotime,Solatran andUnakalm) is a drug which is abenzodiazepine derivative. It possessesanxiolytic,anticonvulsant,sedative andskeletal muscle relaxant properties.

Therapeutic uses

[edit]

It is used for the treatment of anxiety and has similar effectiveness compared to diazepam. Ketazolam also appears to produce reduced levels of side effects such as sedation compared withdiazepam and the side effects when they occur tend to be milder.[3][4][5][6] Ketazolam is also an effective antispasmodic drug and is used for the treatment of spasticity.[7][8][9]

Availability

[edit]

Ketazolam is not approved for sale inNorway,Australia,United Kingdom or theUnited States.[10] InSouth Africa,GlaxoSmithKline markets ketazolam under its Solatran brand name.[11] In Canada, ketazolam is listed in schedule IV of the Controlled Drugs and Substances Act, along with other benzodiazepines.[12]

Tolerance and physical dependence

[edit]

Chronic use of ketazolam as with otherbenzodiazepines can lead tophysical dependence and the appearance of thebenzodiazepine withdrawal syndrome upon cessation of use or decrease in dose.Tolerance to ketazolam's therapeutic effects occurs over a period of 15 days.[13]

Contraindications and special caution

[edit]

Benzodiazepines require special precaution if used in the elderly, during pregnancy, in children, alcohol or drug-dependent individuals and individuals withcomorbidpsychiatric disorders.[14]

Pharmacokinetics

[edit]

Ketazolam breaks down in the blood todiazepam which breaks down todemoxepam which breaks down todesmethyldiazepam.[15]

Warnings

[edit]

The U.S.Food and Drug Administration warns that in Spain, ketazolam marketed as Marcen may sometimes be mistakenly confused with Narcan.[16]

Legal status

[edit]

Ketazolam is a List 3 drug under theBetäubungsmittelgesetz, like almost all benzodiazepines in Germany. Ketazolam is a List II drugs of theOpium Law in theNetherlands. Ketazolam is aSchedule IV drug under the Controlled Substances Act in the US.[17]
