Benzodiazepines
These compounds act on the gamma-aminobutyric acid (GABA) receptors in the brain, enhancing the inhibitory effects of GABA and producing a calming effect.
Benzodiazepines are commonly prescribed for the treatment of anxiety disorders, insomnia, seizures, and alcohol withdrawal.
However, they also carry a risk of dependence and abuse.
Ongoing research aims to explore new therapeutic applications, optimize dosing regimens, and develop safer alternatives for benzodiazepine use.1

We used multivariable logistic regression modelling to determine the adjusted association of prolonged opioid use after discharge (≥1 prescriptions within 1-90 days after surgery along with ≥1 prescriptions within 91-180 days after surgery) with age (categorised as 66-75, 76-85, and ≥86 years), sex, surgery, fifth of neighbourhood income, rural residence, comorbidities (coronary artery disease, heart failure, cerebrovascular disease, peripheral vascular disease, diabetes, hypertension, pulmonary disease, chronic renal insufficiency, malignancy), and preoperative drug use (β blockers, ACE inhibitors, angiotensin receptor blockers, statins, benzodiazepines, SSRIs). All predictor variables were included simultaneously in the multivariable regression model. In the primary analysis, we included all participants in the cohort regardless of whether they survived up to 180 days after surgery. In a sensitivity analysis, we repeated the analyses after restricting the cohort to only those who survived at least 180 days after surgery.

Example 6
The following example provides details of a study used to determine whether alprazolam-induced changes in subjective experience during psilocybin therapy are due to changes in 5-HT2A occupancy. If not, downstream molecular and cellular effects that may be important in psilocybin's therapeutic effects may be preserved after co-treatment with a benzodiazepine.
In this study, [11C]CIMBI-36 (a selective 5-HT2A receptor agonist positron emission tomography (PET) radioligand) will be used to investigate whether 5-HT2A binding is affected by placebo vs. alprazolam.
At time t=0, subjects will be administered 25 mg psilocybin (PSI) in combination with either a placebo, or alprazolam. At t=2 hours, subjects will be given a tracer dose of [11C]CIMBI-36. At t=2-3 hours, a PET scan will be performed, to determine whether 5-HT2A binding is affected by either dose of alprazolam.
This study may optionally be performed using diazepam instead of alprazolam.
Primary presenting substance misuse was reported as opiates (74%), alcohol (13%), and benzodiazepines (13%). Self-identified poor mental health was characterised as suffering from long term depression and anxiety, and 100% had trouble sleeping. 63% of participants reported suicidal ideation within the past 12 months. 25% reported that they had ever been admitted to a psychiatric facility. A minority had psychiatric diagnoses (6%) which were reported as schizophrenia and personality disorder.
Within the previous 12 months, 56% had accessed housing support services, 56% had used substance misuse services, 38% had accessed support for domestic abuse and 25% had accessed mental health support. Fifty percent had visited their GP at least once. Significant acute healthcare use was reported, with at least 18 individual admissions to A&E reported within the group in the previous 12 months.
At baseline and at 6-month intervals afterwards, participants complete interviewer- and nurse-led questionnaires and provide blood samples for serology, as well as urine for drug screening. The questionnaire covers a variety of topics including demographics, substance use, healthcare access, and socio-structural exposures. To compensate participants for their involvement, participants receive a $40 CAD stipend for every study visit.
Due to the COVID-19 pandemic, all in-person data collection was suspended between March 2020 and July 2020. After July 2020, infection control measures were put in place to resume data collection. Participant interviews were completed over telephone or videoconferencing. Study-owned cell phones and private spaces were loaned to those who required them. They were then able to pick up their cash honoraria in person or have it e-transferred if they had access to a bank account.
Between March and July of 2020, study questionnaires were modified to include questions regarding the COVID-19 pandemic. One of these questions was used to assess the primary outcome of this study, which read as follows: “Has the frequency of your use of these sites [i.e., SCS/OPS] changed since the beginning of the public health emergency?”. The outcome was dichotomized using the following responses: “I use them less” vs. “I use them more” or “My use stayed the same”. Potential correlates were identified based on past studies that assessed SCS access among PWUD [8 (link), 25 (link)], and included: age (per year older), self-identified gender (man vs. woman/other), ethnicity/ancestry (white vs. Black, Indigenous, and people of colour), education (high school or greater vs. other), employment (yes vs. no), residence in Downtown Eastside neighbourhood in Vancouver (yes vs. no), daily non-medical prescription opioid use (yes vs. no), daily cocaine use (yes vs. no), daily crystal methamphetamine use (yes vs. no), daily non-injection crack-cocaine use (yes vs. no), benzodiazepine use (yes vs. no), suspected that a drug used contained fentanyl (yes vs. no), used drugs alone (yes vs. no), engagement in opioid agonist therapy (yes vs. no), non-fatal overdose (yes vs. no), witnessed an overdose (yes vs. no), experience physical violence (yes vs. no), syringe/ drug use equipment sharing (yes vs. no), inability to access treatment (yes vs. no), unstable housing (yes vs. no), sex work (yes vs. no), incarceration (yes vs. no), jacked up (this refers to being stopped, searched, or detained) by the police (yes vs. no), cohort/ HIV status (ACCESS vs. VIDUS), ever tested positive for COVID-19 (yes vs. no), concern about COVID-19 on a scale from 1 to 10, with 10 indicating greatest concern (1–5 vs. 6–10), any chronic health conditions (yes vs. no), and ease of accessing SCS/OPS changed since COVID-19 (same vs. easier vs. harder). All drug use and behavioral variables refer to the 6 months prior to questionnaire date unless otherwise indicated.
Univariable and multivariable logistic regression analyses were used to assess the associations between the correlates of interest and reduced frequency of SCS/OPS use since COVID-19. Correlates of interest with a univariable p-value < 0.10 were included in a backward elimination procedure, with the least significant variable removed at each step until the lowest Akaike Information Criterion (AIC) was achieved. All p-values were two-sided and all statistical analyses were conducted using SAS version 9.4 (SAS Institute, Cary, North Carolina, United States).

More about "Benzodiazepines"
These compounds, which include drugs like Diazepam (Valium), act on the gamma-aminobutyric acid (GABA) receptors in the brain, enhancing the inhibitory effects of GABA and producing a calming effect.
Benzodiazepines are commonly prescribed for the treatment of anxiety disorders, insomnia, seizures, and alcohol withdrawal.
However, they also carry a risk of dependence and abuse, which has led to ongoing research to explore new therapeutic applications, optimize dosing regimens, and develop safer alternatives.
The SAS 9.4 software and Stata version 15 are statistical analysis tools that can be used to study the effects and usage of benzodiazepines.
The HiPrep™ 26/10 Desalting Column from GE is a laboratory tool that can be used in benzodiazepine research, while the DrugTest 5000 is a device used for the detection of benzodiazepines and other drugs.
Compounds like Picrotoxin and FG-7142 are also related to benzodiazepines, as they interact with the GABA receptors in the brain and can have similar effects.
Ongoing research aims to explore the full potential of benzodiazepines and develop safer alternatives to address the issues of dependence and abuse.
