Bentazepam[1] (also known asThiadipone,Tiadipona) is athienodiazepine which is abenzodiazepine analog.[2]

It possessesanxiolytic,anticonvulsant,sedative andskeletal muscle relaxant properties.Peak plasma rates are achieved in around 2,5 hours after oral administration.[3] The elimination half-life is between approximately 2–4 hours.[2][4] Bentazepam is effective as an anxiolytic.

A severebenzodiazepine overdose with bentazepam may result in coma and respiratory failure.[5] Adverse effects include dry mouth,somnolence,asthenia,dyspepsia,constipation,nausea[6] and drug-inducedlymphocytic colitis has been associated with bentazepam.[7][8] Severe liver damage and hepatitis has also been associated with bentazepam.[9][10][11] Whilst liver failure from bentazepam is considered to be rare, liver function monitoring has been recommended for all patients taking bentazepam.[12]
