Injury 2024; 55:111606. [PMID: 38834012 DOI: 10.1016/j.injury.2024.111606] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/04/2024] [Revised: 05/06/2024] [Accepted: 05/07/2024] [Indexed: 06/06/2024]
Abstract
INTRODUCTION The use of hypnotic drugs is common in the elderly and is associated with negative health outcomes. Our aim was to evaluate the prevalence of hypnotic drug usage amongst hip fracture patients undergoing a rehabilitation program and investigate any potential associations between hypnotic drug use and rehabilitation outcomes in a post-acute care setting. METHODS A retrospective analysis of 440 geriatric hip fracture patients was conducted from 1/1/2019 to 12/2021 in a geriatric rehabilitation center. The main outcome measures were the Functional Independence Measure (FIM), the motor FIM effectiveness and length of stay (LOS). RESULTS Two hundred and twenty-eight (51.7 %) patients out of the entire cohort (440)), were prescribed hypnotic drugs. These patients exhibited a significantly lower rate of diabetes (p = 0.025), a higher rate of depression (p = 0.003), and lower albumin levels (p = 0.023) upon admission to rehabilitation in comparison to untreated patients. No significant differences were observed between the two patient groups in functional rehabilitation outcomes or LOS. Moreover, no correlation was established between the hypnotic drug burden during rehabilitation and the outcome measures. Furthermore, no significant differences were found between patients treated with hypnotic drugs on admission and those who were prescribed these drugs during rehabilitation. The type of hypnotic drug did not affect these results. CONCLUSION The use of hypnotic drugs by elderly individuals undergoing a rehabilitation program after a hip fracture is unlikely to have an adverse impact on their short-term rehabilitation outcomes. Consequently, there may not be an immediate necessity to discontinue these drugs upon admission. Nevertheless, the use of hypnotic drugs should be approached with caution and minimized whenever possible due to an increased fall risk and other adverse effects.

Ma TT, Wang Z, Qin X, Ju C, Lau WCY, Man KKC, Castle D, Chung Chang W, Chan AYL, Cheung ECL, Chui CSL, Wong ICK. Global trends in the consumption of benzodiazepines and Z-drugs in 67 countries and regions from 2008 to 2018: a sales data analysis. Sleep 2023; 46:zsad124. [PMID: 37094086 DOI: 10.1093/sleep/zsad124] [Citation(s) in RCA: 7] [Impact Index Per Article: 7.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/02/2022] [Revised: 02/16/2023] [Indexed: 04/26/2023] Open
Abstract
STUDY OBJECTIVES To investigate the trends in the consumption of benzodiazepines (BZDs) and Z-drugs at global, regional, and national levels from 2008 to 2018, across 67 countries and regions. METHODS This cross-sectional descriptive study investigated the consumption of BZDs and Z-drugs analyzed by global pharmaceutical sales data from the IQVIA-Multinational Integrated Data Analysis System database between 2008 and 2018. Consumption was measured in defined daily dose (DDD) per 1000 inhabitants per day (DDD/TID). The global, regional, and national trends were estimated using linear mixed models. Additional analyses were conducted by grouping countries by income level. The association between consumption and Gross Domestic Product (GDP) and the prevalence of different medical conditions was explored in univariable linear models. RESULTS BZD consumption decreased annually by -1.88% (95% CI: -2.27%, -1.48%), and Z-drugs increased by + 3.28% (+2.55%, +4.01%). In 2008, the top ten countries for BZD and Z-drug consumption were all European, ranging from 63.69 to 128.24 DDD/TID. Very low levels were found in Russia, Kuwait, United Arab Emirates, Saudi Arabia, French West Africa, and the Philippines, with DDD/TID < 1. The consumption in high-income countries was much higher than in middle-income countries. The results showed that increased consumption of BZDs and Z-drugs was statistically associated (p < 0.05) with higher GDP and increased prevalence of anxiety, self-harm, neurological disorders, chronic respiratory diseases, cardiovascular diseases, and cancers. CONCLUSIONS Distinct differences in consumption and trends of BZDs and Z-drugs were found across different countries and regions. Further exploration is needed to understand the association and safety of the use of BZDs and Z-drugs in patients with comorbidities.

Dispensing of psychotropic drugs in the Brazilian capital city before and during the COVID-19 pandemic (2018-2020). Front Pharmacol 2022; 13:1028233. [PMID: 36618914 PMCID: PMC9822257 DOI: 10.3389/fphar.2022.1028233] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/25/2022] [Accepted: 12/09/2022] [Indexed: 12/24/2022] Open
Abstract
Objective: Evaluate the data on the psychotropic drugs dispensed by private community pharmacies before and during the SARS-CoV-2 pandemic. Methods: This cross-sectional study compared the quarterly and annual consumption of psychotropic drugs per Defined Daily Dose per 1000 inhabitants-day (DHD). Interrupted time series were also constructed to expose changes in the consumption pattern in the periods before and after March 2020. Results: Among the 20 most consumed psychoactive drugs, 12 were antidepressants, for example, escitalopram (DHD 7.996 and 10.626; p < 0.001), and sertraline (DHD 6.321 and 8.484; p < 0.001), in addition to the hypnotic zolpidem (DHD 6.202 and 8.526; p < 0.001). The time series reveals (R 2 value) a variation in drug dispensing, in DHD values, during the pandemic. Conclusion: Despite the higher variance, a significant increase is clearly seen in the consumption trends of psychoactive drugs, particularly antidepressants, consistent with the pandemic's influence on the general population's mental health.

Use of Benzodiazepines and Z-Drugs in Inflammatory Bowel Disease. Am J Gastroenterol 2022; 117:2046-2054. [PMID: 36288107 DOI: 10.14309/ajg.0000000000001955] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/20/2022] [Accepted: 07/29/2022] [Indexed: 12/11/2022]
Abstract
INTRODUCTION We estimated the incidence and prevalence of benzodiazepine and Z-drug (separately and jointly as BZD) use in the inflammatory bowel disease (IBD) population compared with matched controls without IBD and examined the association of mood/anxiety disorders (M/ADs) with the use of BZD from 1997 to 2017. METHODS Using administrative data from Manitoba, Canada, we identified 5,741 persons with incident IBD who were matched in a 1:5 ratio to controls on sex, birth year, and region. Validated case definitions were used to identify M/AD. Dispensations of BZD were identified. Multivariable generalized linear models were used to assess the association between IBD, M/AD, and BZD use. RESULTS In 2016, the incident age/sex-standardized benzodiazepine use rates per 1,000 were 28.06 (95% confidence interval [CI] 26.41-29.81) in the IBD cohort and 16.83 (95% CI 16.28-17.39) in controls (adjusted rate ratio = 1.69 [95% CI 1.56-1.79]). Benzodiazepine incidence rates were higher for women with IBD than men, but the RR between cases and controls were similar for men and women. The incident age/sex-standardized Z-drug use rate per 1,000 was 21.07 (95% CI 19.69-22.41) in the IBD cohort. This was 1.87-fold higher than in controls (95% CI 1.73-2.01). In 2017, approximately 20% of persons with IBD used benzodiazepines and 20% used Z-drugs. There was a subadditive effect of both benzodiazepine and Z-drug uses between IBD and M/AD after adjusting for covariates. DISCUSSION The use of BZD is more common in people with IBD than in population controls. Strategies to reduce the use of BZDs in persons with IBD and to offer alternative management strategies for M/ADs, sleep disorders, and other symptomatic concerns are needed.

Abstract
OBJECTIVE To measure the incidence of long-term benzodiazepine receptor agonist (BZRA) use among individuals with anxiety, mood and/or sleep disorders. To identify factors associated with long-term use following the first prescription. METHODS This was a population-based retrospective cohort study using administrative databases in Manitoba, Canada. Individuals with anxiety/mood or sleep disorder who received their first BZRA between 1 April 2001 and 31 March 2015 were included. Long-term use was defined as ≥180 days. Logistic regression modelling was used to examine predictors of long-term use. RESULTS Among 206 933 individuals included, long-term BZRA use in the first episode of use was 4.5% (≥180 days) following their first prescription. Factors associated with ≥180 days of use included male sex (adjusted OR (aOR) 1.33, 95% CI 1.27 to 1.39), age ≥65 (aOR 5.15, 95% CI 4.81 to 5.52), income assistance (aOR 1.68, 95% CI 1.55 to 1.81), previous non-BZRA psychotropic (aOR 1.93, 95% CI 1.83 to 2.02) or opioid use (aOR 1.16, 95% CI 1.11 to 1.22), high comorbidity (aOR 1.43, 95% CI 1.32 to 1.55), high healthcare use (aOR 1.46, 95% CI 1.33 to 1.60) and psychiatrist prescriber (aOR 2.11, 95% CI 1.93 to 2.32). CONCLUSIONS Less than 1 in 20 patients use BZRAs ≥180 days in their first treatment episode. Several factors were associated with long-term use following the first prescription and further investigation into whether these factors need to be considered at the point of prescribing is warranted. In light of these findings, future research should examine the predictors of cumulative repeat episodes of BZRA exposure.

Trends in the prescription of drugs used for insomnia: an open-cohort study in Australian general practice, 2011-2018. Br J Gen Pract 2021; 71:e877-e886. [PMID: 33950853 PMCID: PMC8366783 DOI: 10.3399/bjgp.2021.0054] [Citation(s) in RCA: 11] [Impact Index Per Article: 3.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/25/2021] [Accepted: 04/19/2021] [Indexed: 12/12/2022] Open
Abstract
BACKGROUND Despite an increase in the prevalence of sleep problems, few studies have investigated changes in the prescribing of drugs that are often used to manage insomnia. AIM To explore changes in the pattern of benzodiazepine (BZD), Z-drug (zolpidem, zopiclone), and non-BZD prescriptions. DESIGN AND SETTING Open-cohort study comprising 1 773 525 patients (55 903 294 consultations) who attended one of 404 Australian general practices at least three times in two consecutive years between 2011 and 2018. METHOD Data were extracted from MedicineInsight, a database of 662 general practices in Australia. Prescription rates per 1000 consultations, the proportion of repeat prescriptions above recommendations, and the proportion of prescriptions for patients with a recent (within 2 years) recorded diagnosis of insomnia were analysed using adjusted regression models. RESULTS Rates of BZD, Z-drug, and non-BZD prescriptions were 56.6, 4.4, and 15.5 per 1000 consultations in 2011 and 41.8, 3.5, and 21.5 per 1000 consultations in 2018, respectively. Over the whole study period, temazepam represented 25.3% of the prescriptions and diazepam 21.9%. All BZD and zolpidem prescriptions declined over the whole study period (annual change varying from -1.4% to -10.8%), but non-BZD and zopiclone prescriptions increased in the same period (annual change 5.0% to 22.6%). Repeat prescriptions that exceeded recommended levels remained at <10% for all medications, except melatonin (64.5%), zolpidem (63.3%), zopiclone (31.4%), and alprazolam (13.3%). In 2018, >50% of Z-drug and melatonin prescriptions were for patients with insomnia. There was an annual increase of 0.8-5.9% in the proportion of prescriptions associated with a recently recorded diagnosis of insomnia. CONCLUSION Overall, BZD prescriptions in Australia declined between 2011 and 2018. However, the prescription of some of these drugs increased for patients with a recently recorded diagnosis of insomnia. This is concerning because of the potential adverse effects of these medications and the risk of dependence.

Abstract
IMPORTANCE The proportion of patients who develop long-term benzodiazepine use remains controversial, as do the length of time before long-term use develops and the factors associated with long-term use. OBJECTIVE To investigate the incidence of long-term benzodiazepine and related drug (BZDR) use and factors associated with the development of long-term use implementing a follow-up design with new BZDR users. DESIGN, SETTING, AND PARTICIPANTS This population-based cohort study used a nationwide cohort of 129 732 new BZDR users in Finland. New users of BZDRs aged 18 years or older were identified from the prescription register maintained by the Social Insurance Institution of Finland as individuals who initiated BZDR use during 2006 and had not used BZDRs from 2004 to 2005. The follow-up continued until death, long-term hospitalization, a gap of 2 years in BZDR use, or December 31, 2015. The population was analyzed according to age at treatment initiation, categorized into younger (<65 years) and older (≥65 years) subcohorts. Analyses were conducted from May 2019 to February 2020. EXPOSURES Use of BZDRs, modeled from register-based data using the PRE2DUP (from prescriptions to drug use periods) method. MAIN OUTCOMES AND MEASURES Long-term BZDR use, defined as continuous use of 180 days or longer, and factors associated with long-term vs short-term use, compared using Cox proportional hazards models. RESULTS Among the 129 732 incident BZDR users, the mean (SD) age was 52.6 (17.7) years, and 78 017 (60.1%) individuals were women. During the follow-up period, 51 099 BZDR users (39.4%) became long-term users. Long-term treatment was more common in the older subcohort (19 103 individuals [54.5%]) than the younger subcohort (31 996 individuals [33.8%]). At 6 months, 28 586 individuals (22.0%) had become long-term users: 11 805 (33.7%) in the older subcohort and 16 781 (17.7%) in the younger subcohort. The largest proportions of initiators who became long-term users were those persons who initiated treatment with nitrazepam (76.4%; 95% CI, 73.6%-79.1%), temazepam (63.9%; 95% CI, 62.9%-65.0%), lorazepam (62.4%; 95% CI, 59.7%-65.1%), or clonazepam (57.5%; 95% CI, 55.9%-59.2%). Factors associated with the development of long-term use included male sex, older age, receipt of social benefits, psychiatric comorbidities, and substance abuse. CONCLUSIONS AND RELEVANCE The findings of this population-based cohort study conducted in Finland suggest that the incidence of subsequent long-term BZDR use in individuals who initiate use of BZDRs is high, especially among older persons, and that the specific BZDR used initially is associated with the development of long-term BZDR use and should be carefully considered when prescribing BZDRs. The observed factors that appear to be associated with development of long-term BZDR use also should be considered in clinical decision-making when starting and monitoring BZDR treatment.

Abstract
Benzodiazepines potentiate respiratory depression when combined with an opioid leading the U.S Food and Drug Administration (FDA) to recommend updating the labels of these products with a boxed warning for respiratory depression with co-use. Potential respiratory depression upon co-administration of opioids with some psychotropic drugs is not well understood. The FDA is currently investigating various psychotropic drug interactions with the commonly used opioid, oxycodone, in a rat model assessing respiratory depression. Pharmacokinetic and/or pharmacodynamic (PK/PD) interaction between oxycodone and diazepam was evaluated in a positive control arm of these experiments. Understanding the systemic exposure of these drugs alone and in combination exposures was used to identify PK/PD interactions. The authors developed a simple, high throughput liquid chromatography-tandem mass spectrometric (LC-MS/MS) assay for the simultaneous determination of oxycodone and diazepam in rat plasma. Sample preparation was performed in 96-well protein precipitation plates using acetonitrile. Processed samples were analyzed using a C18 column with a gradient mobile phase composed of 2 mM aqueous ammonium formate with 0.1% formic acid and acetonitrile. A Thermo TSQ Quantum Ultra AM triple quadrupole mass spectrometer with multiple reaction monitoring (MRM) mode was used to acquire data. The method was validated for selectivity, specificity, linearity, precision and accuracy, dilution integrity and stability. The validated LC-MS/MS assay was utilized for quantifying oxycodone and diazepam in concomitantly treated Sprague Dawley (SD) rats. A high-throughput bioanalytical method for the simulataneous determination of oxycodone and diazepam to support the evaluation of respiratory depression in rats upon co-administration of oxycodone and diazepam.![]()

Abstract
Drug utilization research on benzodiazepines remains important for measuring trends in consumption within and across borders over time for the sake of monitoring prescribing patterns and identifying potential population safety concerns. The defined daily dose (DDD) system by the World Health Organization (WHO) remains the internationally accepted standard for measuring drug consumption; however, beyond consumption, DDD-based results are difficult to interpret when individual agents are compared with one another or are pooled into a total class-based estimate. The diazepam milligram equivalent (DME) system provides approximate conversions between benzodiazepines and Z-drugs (i.e. zopiclone, zolpidem, zaleplon) based on their pharmacologic potency. Despite this, conversion of total dispensed benzodiazepine quantities into DME values retains diazepam milligrams as the total unit of measurement, which is also impractical for population-level interpretation. In this paper, we propose the use of an integrated DME-DDD metric to obviate the limitations encountered when the component metrics are used in isolation. Through a case example, we demonstrate significant change in results between the DDD and DME-DDD method. Unlike the DDD method, the integrated DME-DDD metric offers estimation of population pharmacologic exposure, and enables superior interpretation of drug utilization results, especially for drug class summary reporting.

Abstract
PURPOSE Long-term benzodiazepine (BZD) treatment continues to be a debated topic. Because individual BZDs have different clinical profiles, we assessed the nationwide trends of long-term BZD use at active substance level during years 2006 to 2014. METHODS This study covered all reimbursed BZD purchases (n = 408 572-521 823 annually) for adults recorded in the Finnish Prescription Register. We assessed long-term use (annual cumulative purchase of ≥180 defined daily doses) in general, and at active substance level with the most commonly used BZD anxiolytics (oxazepam, diazepam, alprazolam, and clonazepam for nonepilepsy indications) and hypnotics (zopiclone, zolpidem, and temazepam) included. The persistence rates for each substance were assessed separately. RESULTS The prevalence of long-term BZD use among Finnish adults declined significantly from 5.3% to 3.6%, during years 2006 to 2014. Despite this decline, there was a significant increase in the long-term use of clonazepam for nonepilepsy indications and zolpidem (28.0% and 17.5%, respectively). Long-term use was common in the aged population, as well as among the users of hypnotics or clonazepam. Persistent use of 9 consecutive calendar years varied between 7.5% for incident alprazolam users and 21.0% for incident clonazepam users. CONCLUSIONS We found a declining trend in long-term BZD use, but the decline was not uniform between the substances-the long-term use of clonazepam and zolpidem even increased. Follow-up research is needed to assess whether the decline in BZD use is accompanied by an increased use of other types of anxiolytic or hypnotic drugs or other forms of treatment.
