A survey of Mohs surgery specialists in Australia showed diazepam was the preferred agent and felt to be the safest oral benzodiazepine for perioperative anxiolysis.

UNASSIGNED: This study aimed to evaluate the aetiology, management and outcomes of convulsive status epilepticus (CSE) in children and highlight the factors influencing patient outcomes in such cases.
UNASSIGNED: In a retrospective study spanning the 2020-2023 period, 93 children with CSE treated at Sultan Qaboos University Hospital\'s emergency department (ED), high dependency unit (HDU) and intensive care unit (ICU) were analysed. The Modified Rankin Scale at discharge was used to determine CSE outcomes.
UNASSIGNED: Among the 93 children studied (mean age 4.84 ± 3.64 years), predominantly Omani (92.47%), 14 aetiologies were noted. Of them, acute symptomatic (37.7%) and febrile status (31.2%) were the primary causes of CSE. Diazepam was administered as the first-line treatment in 58 (67.44%) cases, with a median seizure duration of 45 minutes. Successful seizure control was achieved in 71 (76.34%) cases within 60 minutes. A return to baseline was observed in 55.9% of cases, while mortality and disability were noted in 5.38% and 38.7% of cases, respectively. For 17 cases, aetiology and duration significantly impacted patient outcomes (P <0.05).
UNASSIGNED: Acute symptomatic status is the most common aetiology of CSE. A longer duration of CSE is associated with higher mortality and neurological disability. Prompt and appropriate management of CSE is essential. Furthermore, identifying and treating the underlying cause of CSE is a crucial step in reducing its duration and improving patient outcomes.

BACKGROUND: Benzodiazepines are frequently prescribed to treat anxiety and insomnia, but long-term use has been associated with the development of dependence, tolerance, and cognitive decline, especially among older adults. This study aimed to investigate the pattern of consumption and factors associated with inappropriate prescribing of benzodiazepines in primary health care.
METHODS: This is a cross-sectional analytical study, using dispensing records of diazepam, clonazepam, and nitrazepam from public pharmacies in a Brazilian municipality between 2018 and 2022. Metrics for benzodiazepine consumption were DDD (Defined Daily Dose) and DDD/1000PD (per 1000 population per day). Long-term/prolonged benzodiazepine use was defined as consuming at least 90 DDD and at least 2 dispensations per year. To ascertain associations between long-term use and predictor variables, a multivariate logistic regression model was utilized.
RESULTS: A total of 40402 participants were included, with an average age of 55 years (SD = 0.30), 38.5% were older aged. Diazepam and nitrazepam exceeded the daily dose recommended. There was a reduction in diazepam consumption during the study period, as calculated by DDD/1.000PD, while the consumption of other benzodiazepines remained stable. However, a significant increase in diazepam consumption is noted when considering the last decade. Prolonged use was observed in 29.1% of participants, with a significant prevalence among the older people (34.8% of them were long-term users) and advancing age was identified as a risk factor for long-term use. Higher PDDs were also associated with long-term use and aging. Participants who used different benzodiazepines during the period had a higher risk of prolonged use.
CONCLUSIONS: These results provide insights into the prevalence of problematic utilization of benzodiazepines in primary health care. Authorities and health care providers must take steps to encourage gradual cessation of prolonged benzodiazepine prescriptions and the embrace of suitable strategies for addressing anxiety and insomnia within primary health care settings.

The soy isoflavone daidzin (DZN) has been considered a hopeful bioactive compound having diverse biological activities, including anxiolytic, memory-enhancing, and antiepileptic effects, in experimental animals. However, its sedative and hypnotic effects are yet to be discovered. This study aimed to evaluate its sedative/hypnotic effect on Swiss mice. Additionally, in silico studies were also performed to see the possible molecular mechanisms behind the tested neurological effect. For this, male Swiss albino mice were treated with DZN (5, 10, or 20 mg/kg) intraperitoneally (i.p.) with or without the standard GABAergic medication diazepam (DZP) and/or flumazenil (FLU) and checked for the onset and duration of sleeping time using thiopental sodium-induced as well as DZP-induced sleeping tests. A molecular docking study was also performed to check its interaction capacity with the α1 and β2 subunits of the GABAA receptor. Findings suggest that DZN dose-dependently and significantly reduced the latency while increasing the duration of sleep in animals. In combination therapy, DZN shows synergistic effects with the DZP-2 and DZP-2 + FLU-0.01 groups, resulting in significantly (p < 0.05) reduced latency and increased sleep duration. Further, molecular docking studies demonstrate that DZN has a strong binding affinity of - 7.2 kcal/mol, which is closer to the standard ligand DZP (- 8.3 kcal/mol) against the GABAA (6X3X) receptor. Molecular dynamic simulations indicated stability and similar binding locations for DZP and DZN with 6X3X. In conclusion, DZN shows sedative effects on Swiss mice, possibly through the GABAA receptor interaction pathway.

OBJECTIVE: This retrospective multicenter cohort study aimed to investigate the impact of diazepam administration during embryo transfer on reproductive outcomes, focusing primarily on the live birth rate. Secondary outcomes included the positive beta-hCG rate, clinical pregnancy rate, miscarriage rate, ectopic pregnancy rate, and preterm birth rate.
METHODS: Data from 5607 embryo transfers, encompassing 465 cases with diazepam administration, were retrospectively analyzed. The study included single blastocyst transfers from 12 clinics in Portugal and Spain between January 2015 and December 2022.
RESULTS: Comparison of reproductive outcomes between patients receiving diazepam and those who did not showed no statistically significant differences. Positive beta-hCG rates (60.8% non-diazepam vs. 60.4% diazepam, p = 0.92, adjusted p = 0.32) and clinical pregnancy rates (45.6% non-diazepam vs. 46.2% diazepam, p = 0.81, adjusted p = 0.11) were comparable. Miscarriage rates (11.0% diazepam vs. 9.3% non-diazepam, p = 0.25, adjusted p = 0.26) and ectopic pregnancy rates (0.9% diazepam vs. 0.1% non-diazepam, p = 0.1, adjusted p = 0.20) were similar. Live birth rates (36.3% non-diazepam vs. 35.3% diazepam, p = 0.69, adjusted p = 0.82) and prematurity rates (0.3% non-diazepam vs. 0% diazepam, p > 0.99, adjusted p = 0.99) also exhibited no statistically significant differences.
CONCLUSIONS: Based on the results, diazepam administration during embryo transfer did not show a discernible impact on reproductive outcomes, including live birth rates, suggesting its limited effectiveness in enhancing success.

Previous studies have indicated a close association between cognitive impairment in patients with neurodegenerative diseases, such as Alzheimer\'s disease (AD), and synaptic damage. Diazepam (DZP), a benzodiazepine class drug, is used to control symptoms such as seizures, anxiety, and sleep disorders. These symptoms can potentially manifest throughout the entire course of AD. Therefore, DZP may be utilized in the treatment of AD to manage these symptoms. However, the specific role and mechanisms of DZP in AD remain unclear. In this study, we discovered that long-term administration of a low dose of DZP (0.5  mg/kg) improved cognitive function and protected neurons from damage in APP/PS1 mice. Mechanistic investigations revealed that DZP exerted its neuroprotective effects and reduced Aβ deposition by modulating GluA1 (glutamate AMPA receptor subunit) to influence synaptic function. In conclusion, these findings highlight the potential benefits of DZP as a novel therapeutic approach, suggesting that long-term use of low-dose DZP in early-stage AD patients may be advantageous in slowing disease progression.

Diazepam (DZP) is a sedative medication prescribed to treat anxiety and as a sleep inducer, although its residual effects are unfavorable to patients. Nanotechnology represents a tool to improve the pharmacological characteristics of drugs, reducing their side effects. This study aimed to develop and characterize DZP nanocapsules and to evaluate their toxicity in alternative models and the hypnotic-sedative effect in mice. Nanocapsules were prepared by the nanoprecipitation method and properly characterized. Long-term and accelerated stability studies were performed. The in vitro release profile was determined by diffusion in Franz cells. The safety of the formulation was evaluated in the Caenorhabditis elegans (C. elegans) and the oral acute toxicity in mice. Pharmacological evaluation was performed using thiopental-induced sleeping time. DZP was successfully incorporated into Poly-(ɛ-caprolactone) (PCL) nanocapsules, with high entrapment efficiency. The nanocapsule did not affect the development or survival of C. elegans, different from the free drug, which affected the nematode development at the higher tested dose. No signs of toxicity, nor body mass or feed consumption changes were observed during the 14 days evaluated. Finally, this innovative formulation carrying DZP can produce a hypnotic-effect at a reduced dose compared to the free drug, with no toxicity in alternative models.

Diazepam (DZP) is a universally detected emerging pollutant in aquatic ecosystems. Although the sex-dependent effects of DZP on fish have been properly established, the underlying mechanisms remain unclear. In this study, zebrafish of both sexes were separately exposed to DZP (8 μg/L) for 21 days, and the alteration of the behaviors, brain amino acid neurotransmitter contents, and transcriptomic profiles were investigated. Although DZP exposure showed a sedative effect on both sexes, significantly reduced cumulative duration of high mobility and willingness to encounter the opposite sex were only observed in females. However, DZP significantly enhanced the brain levels of glutamate and glutamine in males but not in females. Transcriptome analysis identified more different expression genes (DEGs) in females (322 up-regulated and 311 down-regulated) than in males (138 up-regulated genes and 38 down-regulated). The DEGs in both sexes were significantly enriched in the KEGG (Kyoto Encyclopedia of Genes and Genomes) pathway of the synaptic vesicle cycle, indicating a possible pathway for the sedative effects of DZP on zebrafish. DZP exhibited different or even opposing regulatory patterns on gene expression in the brains of females and males, providing some insights into its sex-dependent impacts on the behaviors and brain neurotransmitter contents in zebrafish. Moreover, enrichment analysis also suggested that DZP exposure may affect the oocyte maturation in female zebrafish, which highlights the need to study its reproductive and transgenerational toxicity to fish species.

BACKGROUND: Benzodiazepines are used in first-line rescue therapy as immediate-use seizure medication for the treatment of seizure clusters and prolonged seizures. Their use varies across clinical practices and conditions, and they can be used promptly when indicated. Clinical studies have demonstrated seizure termination within 2 min when diazepam nasal spray is used to treat seizure clusters within 5 min, but the response when treating longer duration seizures in a cluster remains to be characterized.
OBJECTIVE: To describe and assess timing and dosing of diazepam nasal spray in the subset of prolonged seizures within seizure clusters in a larger dataset of all treated seizure clusters collected during a long-term safety study of diazepam nasal spray.
METHODS: Using timing data recorded in seizure diaries, this post hoc analysis and associated sensitivity analyses focused on prolonged seizures treated 5 to 15 min after the seizure start. Measures included time to treatment administration and time to seizure termination. Second-dose data were used as a proxy for effectiveness.
RESULTS: In this group of seizure clusters treated 5 to 15 min after seizure start, median time drug administration was 6 min after seizure start, median time from drug administration to seizure termination was 7 min, and median overall seizure duration was 15 min. Sensitivity analyses by age, epilepsy type, and high seizure frequency confirmed this pattern. Use of a second dose occurred in 9.3 % of episodes, with the majority of second doses administered ≤ 4 h after the first dose. Safety results from the overall study showed 82.2 % of patients had ≥ 1 treatment-emergent adverse event (TEAE) irrespective of relationship to treatment, during a mean participation of ∼ 1.5 years. In addition, 30.7 % patients had a serious TEAE, and 18.4 % had TEAEs deemed at least possibly related to the study drug, none of which were serious. No events of cardiorespiratory depression were reported.
CONCLUSIONS: Although immediate use of diazepam nasal spray (within 5 min) resulted in quicker seizure termination, a treatment delay of 5 to 15 min still produced rapid termination of the seizure cluster with high first-dose effectiveness and an overall acceptable safety profile. These findings suggest that diazepam nasal spray maintains effectiveness in prolonged seizures within a cluster with delayed treatment.

Insomnia is a sleep disorder in which you have trouble falling and/or staying asleep. This research aims to evaluate the sedative effects of fraxin (FX) on sleeping mice induced by thiopental sodium (TS). In addition, a molecular docking study was conducted to investigate the molecular processes underlying these effects. The study used adult male Swiss albino mice and administered FX (10 and 20 mg/kg, i.p.) and diazepam (DZP) (2 mg/kg) either separately or in combination within the different groups to examine their modulatory effects. After a period of 30 min, the mice that had been treated were administered (TS: 20 mg/kg, i.p.) to induce sleep. The onset of sleep for the mice and the length of their sleep were manually recorded. Additionally, a computational analysis was conducted to predict the role of gamma-aminobutyric acid (GABA) receptors in the sleep process and evaluate their pharmacokinetics and toxicity. The outcomes indicated that FX extended the length of sleep and reduced the time it took to fall asleep. When the combined treatment of FX and DZP showed synergistic sedative action. Also, FX had a binding affinity of -7.2 kcal/mol, while DZP showed -8.4 kcal/mol. The pharmacokinetic investigation of FX demonstrated favorable drug-likeness and strong pharmacokinetic characteristics. Ultimately, FX demonstrated a strong sedative impact in the mouse model, likely via interacting with the GABAA receptor pathways.
