Symptoms. Effects of long-term benzodiazepine use may include disinhibition, impaired concentration and memory, depression, [ 19 ][ 20 ] as well as sexual dysfunction. [ 6 ][ 21 ] The long-term effects of benzodiazepines may differ from the adverse effects seen after acute administration of benzodiazepines. [ 22 ]
Benzodiazepines potentiate the action of GABA, [54] by binding a site between the α and γ subunits of the 5-subunit receptor [55] thereby increasing the frequency of the GABA-gated chloride channel opening in the presence of GABA. [56] When potentiation is sustained by long-term use, neuroadaptations occur which result in decreased GABAergic ...
The long-term effects of benzodiazepines are still not fully understood. Long-term benzodiazepine use is associated with attentional and visuospatial functional impairments. Withdrawal from benzodiazepines can lead to improved alertness and decreased forgetfulness in the elderly. Withdrawal led to statistically significant improvements in ...
A number of studies have drawn an association between long-term benzodiazepine use and neuro-degenerative disease, particularly Alzheimer's disease. [150] It has been determined that long-term use of benzodiazepines is associated with increased dementia risk, even after controlling for protopathic bias. [13]
Long-acting benzodiazepines with long-acting active metabolites, such as diazepam and chlordiazepoxide, are often prescribed for benzodiazepine or alcohol withdrawal as well as for anxiety if constant dose levels are required throughout the day. Shorter-acting benzodiazepines are often preferred for insomnia due to their lesser hangover effect.
The risk and severity of withdrawal are increased with long-term use, use of high doses, abrupt or over-rapid reduction, among other factors. Short-acting benzodiazepines such as lorazepam are more likely to cause a more severe withdrawal syndrome compared to longer-acting benzodiazepines. [20]
Benzodiazepine use disorder (BUD), also called misuse or abuse, [ 1 ] is the use of benzodiazepines without a prescription and/or for recreational purposes, which poses risks of dependence, withdrawal and other long-term effects. [ 2 ][ 3 ] Benzodiazepines are one of the more common prescription drugs used recreationally.
t. e. Benzodiazepine overdose (BZD OD) describes the ingestion of one of the drugs in the benzodiazepine class in quantities greater than are recommended or generally practiced. The most common symptoms of overdose include central nervous system (CNS) depression, impaired balance, ataxia, and slurred speech.
