Nationwide database analysis of insomnia, depression, and sleeping pill prescriptions in hepatocellular carcinoma patients.

OBJECTIVE: To clarify the status of insomnia and depression and the prescription of sleeping pills in hepatocellular carcinoma (HCC) patients before and after HCC diagnosis and treatment. METHODS: Patients' data from a Japanese health insurance claims database were analyzed retrospectively to determine the incidence of insomnia and depression and their association with sleeping pill prescriptions during the 6 months before and after HCC diagnosis and treatment. RESULTS: A total of 9,109 HCC patients (median age at diagnosis = 71.5 years, 68.1% male) were analyzed. The incidences of insomnia and depression increased significantly after HCC diagnosis. Insomnia was reported in 15.0% of patients before diagnosis, and it increased to 27.6% after diagnosis. Similarly, depression was reported in 6.3% and 11.3% before and after diagnosis, respectively. The incidences of insomnia and depression before diagnosis were higher in patients with concomitant liver diseases including hepatitis, cirrhosis, and hepatic encephalopathy. However, the rate of sleeping pill prescription was significantly lower in patients with concomitant liver diseases after diagnosis. The incidence of fracture was higher in insomnia or depression patients than others and in patients treated with sleeping pills than without before and after diagnosis. CONCLUSIONS: HCC patients had increased risks of insomnia and depression after diagnosis. The high risk of fracture in HCC patients with insomnia and depression and treated with sleeping pills suggests that it is difficult to optimize the management of HCC patients, especially those with concomitant liver diseases.

Application of Chaihu-Guizhi-Longgu-Muli decoction combined with Liuwei Dihuang Pills in the treatment of menopausal insomnia and its effect on sleep quality.

To explore the application of Chaihu-Guizhi-Longgu-Muli decoction (CGLM) combined with Liuwei Dihuang Pills in the treatment of menopausal insomnia and its effect on sleep quality. The data of 120 menopausal insomnia patients admitted to our hospital from February 2019 to February 2020 were retrospectively analyzed and they were equally divided into the experimental group (n=60) and the control group (n=60) according to the order of admission. All patients were treated with Liuwei Dihuang Pills, and the experimental group was additionally given CGLM. The Pittsburgh Sleep Quality Index (PSQI), estrogen level, negative emotion score, quality of life score, serum ß-endorphin (ß-EP) level, serotonin level (5-HT) and treatment effective rate were compared between the two groups of patients. After treatment, the experimental group obtained markedly lower PSQI scores and negative emotion scores than the control group (P<0.001). The estrogen levels, ß-EP levels and 5-HT levels of the experimental group after treatment were significantly better than those of the control group (P<0.001). Higher quality of life scores and treatment effective rates were observed in the experimental group after treatment than the control group (P<0.001). CGLM combined with Liuwei Dihuang Pills can regulate the serum hormone levels of patients with menopausal insomnia, reduce negative emotions and improve sleep quality and quality of life, which merits clinical promotion.

Insomnia: Pharmacologic Treatment.

Insomnia afflicts many geriatric patients worldwide and results in both clinical and economic consequences. Prescribing hypnotics to the elderly is particularly challenging due to multitudes of adverse effects and drug interactions. Although benzodiazepines and "Z" drugs such as zolpidem have been popular in the past, they carry a high risk of adverse effects in the elderly, such as devastating falls and injuries as well as potentially an increase in mortality. Newer classes of hypnotics such as dual orexin receptor antagonists are much better tolerated and can be explored as a potential treatment for insomnia in the elderly.

Effects of Bedtime Dosing With Suvorexant and Zolpidem on Balance and Psychomotor Performance in Healthy Elderly Participants During the Night and in the Morning.

PURPOSE/BACKGROUND: This study was designed as an early assessment of the safety of the orexin receptor antagonist suvorexant, but also included exploratory assessments of balance and psychomotor performance that are the focus of this report. METHODS/PROCEDURES: This was a double-blind, randomized, 3-period, crossover, phase 1 study. Balance and psychomotor performance were evaluated during the night in 12 healthy elderly participants after bedtime administration of suvorexant 30 mg (a supratherapeutic dose), the GABAergic agonist zolpidem 5 mg (the recommended dose in the elderly), or placebo. Balance (body sway measured by platform stability) and psychomotor performance (measured by choice reaction time) were assessed predose and at 1.5, 4, and 8 hours postdose in each period. Memory (measured by word recall) was assessed predose and at 4 hours postdose. FINDINGS/RESULTS: At 1.5 hours after nighttime administration of each drug (the approximate time of their anticipated maximal plasma concentrations), both zolpidem and suvorexant increased body sway versus placebo, with a greater increase for zolpidem than suvorexant. Suvorexant increased choice reaction time compared with placebo or zolpidem at 1.5 hours. There were no treatment differences on body sway or choice reaction time at 4 or 8 hours, or on word recall at 4 hours. IMPLICATIONS/CONCLUSIONS: These exploratory data suggest that a 30-mg dose of suvorexant (supratherapeutic) and a 5-mg dose of zolpidem (recommended dose in the elderly) impaired balance at 1.5 hours in healthy elderly people, with potentially less impairment for suvorexant relative to zolpidem, but no treatment differences on body sway or psychomotor performance at 4 and 8 hours. Because of their exploratory nature, these findings and their clinical relevance, if any, require confirmation in a prospective study.

Effect of hepatic impairment on pharmacokinetics, safety, and tolerability of lemborexant.

Lemborexant, a dual orexin receptor antagonist, is approved in the United States, Japan, and Canada for the treatment of insomnia in adults. This phase I, multicenter, open-label, parallel-group study assessed the impact of mild or moderate hepatic impairment (HI) on lemborexant pharmacokinetics and metabolism. The pharmacokinetics, tolerability, and safety of lemborexant were evaluated in subjects with mild (Child-Pugh class A) or moderate (Child-Pugh class B) HI and healthy age-, sex-, and body mass index (BMI)-matched control subjects (n = 8 subjects/group). Subjects received a single oral dose of lemborexant 10 mg (LEM10). Blood samples were collected up to 312 hours post dosing for lemborexant pharmacokinetics assessments. Median time to maximum plasma concentration was similar across all groups. Compared with healthy subjects, exposure measures (maximum plasma concentration [Cmax ] and area under the curve extrapolated to infinity [AUC0-inf ]) increased by ~58% (Cmax ) and ~25% (AUC0-inf ) in subjects with mild HI and ~22% (Cmax ) and ~54% (AUC0-inf ) in subjects with moderate HI. Clearance decreased by 20% and 35% in subjects with mild and moderate HI, respectively, versus healthy subjects. Lemborexant unbound fraction was similar in all groups (range: 0.060-0.065). All treatment-emergent adverse events (TEAEs) were mild in severity; no serious TEAEs occurred. In conclusion, following a single LEM10 dose, lemborexant exposure was similar in subjects with mild HI and increased in subjects with moderate HI versus healthy subjects. No dose adjustment is required in subjects with mild HI. Dosing in subjects with moderate HI should be restricted to 5 mg. Lemborexant was well tolerated in all groups.

Investigation of the effect of the dual orexin receptor antagonist almorexant on ophthalmological, spermatogenic, and hormonal variables in healthy male subjects.

BACKGROUND/AIMS: The aim of this single-center, double-blind study was to investigate the effect of a 4-week once daily administration of 200 mg almorexant on tear film break-up time, spermatogenesis, hormone levels, and pancreatic elastase in stool in healthy male subjects. METHODS: Almorexant 200 mg or matching placebo was administered in the evening for 4 weeks once daily to 56 healthy male subjects. Changes in ophthalmological variables, sperm composition, hormone levels, and pancreatic elastase levels in stool were evaluated periodically up to 8 weeks after discontinuation of drug administration. Blood samples for pharmacokinetic measurements were taken after 4 weeks to confirm compliance to study drug intake. RESULTS: The results of this study revealed no treatment effects of almorexant, neither on tear film break-up time nor on other ophthalmological variables investigated during this study. Furthermore, spermatogenesis, hormones of the hypothalamic-pituitary-adrenal and -gonadal axes, and endocrine pancreatic secretion were shown to be not affected by a 4-week once daily administration of almorexant. CONCLUSION: Almorexant was well tolerated and had no effect on the spectrum of pharmacodynamic variables assessed. Ophthalmology and testicular findings detected in preclinical studies were not observed in this clinical study. Therefore, these preclinical findings appear not to be relevant for humans and do not prevent from conducting larger clinical trials with either healthy subjects or patients.

Zolpidem Versus Trazodone Initiation and the Risk of Fall-Related Fractures among Individuals Receiving Maintenance Hemodialysis.

BACKGROUND AND OBJECTIVES: Zolpidem, a nonbenzodiazepine hypnotic, and trazodone, a sedating antidepressant, are the most common medications used to treat insomnia in the United States. Both drugs have side effect profiles (e.g., drowsiness, dizziness, and cognitive and motor impairment) that can heighten the risk of falls and fractures. Despite widespread zolpidem and trazodone use, little is known about the comparative safety of these medications in patients receiving hemodialysis, a vulnerable population with an exceedingly high fracture rate. DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS: Using data from the United States Renal Data System registry (2013-2016), we conducted a retrospective cohort study to investigate the association between the initiation of zolpidem versus trazodone therapy and the 30-day risk of hospitalized fall-related fractures among Medicare-enrolled patients receiving maintenance hemodialysis. We used an active comparator new-user design and estimated 30-day inverse probability of treatment-weighted hazard ratios and risk differences. We treated death as a competing event. RESULTS: A total of 31,055 patients were included: 18,941 zolpidem initiators (61%) and 12,114 trazodone initiators (39%). During the 30-day follow-up period, 101 fall-related fractures occurred. Zolpidem versus trazodone initiation was associated with a higher risk of hospitalized fall-related fracture (weighted hazard ratio, 1.71; 95% confidence interval, 1.11 to 2.63; weighted risk difference, 0.17%; 95% confidence interval, 0.07% to 0.29%). This association was more pronounced among individuals prescribed higher zolpidem doses (hazard ratio, 1.85; 95% confidence interval, 1.10 to 3.01; and risk difference, 0.20%; 95% confidence interval, 0.04% to 0.38% for higher-dose zolpidem versus trazodone; and hazard ratio, 1.60; 95% confidence interval, 1.01 to 2.55 and risk difference, 0.14%; 95% confidence interval, 0.03% to 0.27% for lower-dose zolpidem versus trazodone). Sensitivity analyses using longer follow-up durations yielded similar results. CONCLUSIONS: Among individuals receiving maintenance hemodialysis, zolpidem initiators had a higher risk of hospitalized fall-related fracture compared with trazodone initiators.

Z-drugs and Falls: A Focused Review of the Literature.

OBJECTIVE: To provide a focused review of the literature related to the association between exposure to Z-drugs and the risk of falls, especially in the older population.
DATA SOURCES: A literature search was conducted using Medline, PsychInfo, and the Cochrane Library database for all clinical trials, case series, and case reports published in English up to May 2020. The search terms used consisted of each Z-drug, including "zolpidem," "zopiclone," "eszopiclone," and "zaleplon," matched with "falls."
STUDY SELECTION: The search yielded 295 studies. After review of abstracts, content and references were reviewed, and duplicates removed, a total of 9 articles met inclusion of exposure to at least 1 Z-drug and a primary outcome of falls.
DATA EXTRACTION: The American Geriatrics Society 2019 Beers Criteria Update for Potentially Inappropriate Medication Use in Older Adults recommends to avoid using nonbenzodiazepine hypnotics in this patient population because of the risk of adverse events.
DATA SYNTHESIS: A majority of the literature suggests an increased risk of falls with exposure to Z-drug use, especially zolpidem. Eight trials examined falls as a primary outcome in non-elderly (n=3) and elderly (n=5) patients in different settings, mostly in an inpatient setting (nursing facility or acute care hospital).
CONCLUSION: Exposure to Z-drugs, especially zolpidem, should be evaluated and counseled on continuously as these medications put patients at an increased risk for falls and other complications.

Clinical pharmacology, efficacy, and safety of orexin receptor antagonists for the treatment of insomnia disorders.

INTRODUCTION: The last two decades have witnessed a rapid increase in the knowledge about the role of the orexin system, particularly in the regulation of wakefulness and arousal. Dual orexin receptor antagonists (DORAs) have been approved for the treatment of insomnia disorders (suvorexant, lemborexant) and drugs with a distinctive profile (daridorexant) or orexin-2 receptor selectivity (seltorexant) are in development. AREAS COVERED: This review discusses pharmacokinetics (PK), pharmacodynamics (PD), efficacy, and safety properties of orexin receptor antagonists (ORAs). EXPERT OPINION: In general, the drugs described have a similar effect on sleep characteristics although their pharmacokinetic variables differ. ORAs have the potential to revolutionize the pharmacological treatment of insomnia because they not only improve sleep, but, in addition, appear to have no dependence - and tolerance-inducing effects, which makes them suitable for long-term-treatment. The safety and tolerability profile of ORAs clearly differ from those of more traditional sleep-promoting drugs. Further research is needed to demonstrate benefits to patients suffering from insomnia disorder, e.g., with respect to improving not only sleep but also daytime functioning. In addition, ongoing and future research will show whether ORAs may have beneficial effects in patients with various psychiatric and neurodegenerative disorders, including Alzheimer's disease.

Non-GABA sleep medications, suvorexant as risk factors for falls: Case-control and case-crossover study.

The aim of this study was to examine the risk of falls associated with the use of non-gamma amino butyric acid (GABA) sleep medications, suvorexant and ramelteon. This case-control and case-crossover study was performed at the Kudanzaka Hospital, Chiyoda Ward, Tokyo. A total of 325 patients who had falls and 1295 controls matched by sex and age were included. The inclusion criteria for the case group were hospitalized patients who had their first fall and that for the control were patients who were hospitalized and did not have a fall, between January 2016 and November 2018. The internal sleep medications administered were classified as suvorexant, ramelteon, non-benzodiazepines, benzodiazepines, or kampo. In the case-control study, age, sex, clinical department, the fall down risk score, and hospitalized duration were adjusted in the logistic regression model. In the case-control study, multivariable logistic regression showed that the use of suvorexant (odds ratio [OR]: 2.61, 95% confidence interval [CI]: 1.29-5.28), nonbenzodiazepines (OR: 2.49, 95% CI: 1.73-3.59), and benzodiazepines (OR: 1.65, 95% CI: 1.16-2.34) was significantly associated with an increased OR of falls. However, the use of ramelteon (OR: 1.40, 95% CI: 0.60-3.16) and kampo (OR: 1.55, 95% CI: 0.75-3.19) was not significantly associated with an increased OR of falls. In the case-crossover study, the use of suvorexant (OR: 1.78, 95% CI: 1.05-3.00) and nonbenzodiazepines (OR: 1.63, 95% CI: 1.17-2.27) was significantly associated with an increased OR of falls. Similar patterns were observed in several sensitivity analyses. It was suggested that suvorexant increases the OR of falls. This result is robust in various analyses. This study showed that the risk of falls also exists for non-GABA sleep medication, suvorexant, and thus it is necessary to carefully prescribe hypnotic drugs under appropriate assessment.

Suvorexant for the prevention of delirium: A meta-analysis.

BACKGROUND: Delirium is a frequently encountered complication, which is associated with increased mortality. Suvorexant, an approved agent for the treatment of insomnia, is recently suggested to be also effective for prevention of delirium by some authors. However, a consensus has yet to be reached. The goal of this study was to perform a meta-analysis to overall estimate the effectiveness of suvorexant in preventing delirium and its related consequences. METHODS: Eligible studies were identified by searching online databases of PubMed, EMBASE, and Cochrane Library. The pooled OR was calculated for binary outcomes (e.g., the incidence of delirium, mortality, or adverse events), while standardized mean difference (SMD) were expressed for continuous outcomes (e.g., time to delirium onset, length of stay in hospital and ICU, time on ventilation). RESULTS: Seven studies which comprised 402 suvorexant treatment patients and 487 patients with control treatment were included in this meta-analysis. Overall, pooled analysis indicated the incidence of delirium could be significantly reduced (OR, 0.30; P < .001) and time to delirium onset was significantly lengthened (SMD, 0.44; P = .006) in patients undergoing suvorexant treatment compared with controls. Suvorexant had no beneficial effects on the secondary outcomes [length of stay in hospital (SMD, -0.65; P = .161) and ICU (SMD, 0.34; P = .297), time on ventilation (SMD, 1.09; P = .318), drug-related adverse events (OR, drug-related adverse events (OR, 1.66; P = .319) and mortality (OR, 2.21; P = .261)]. Subgroup analysis also confirmed the benefit of suvorexant on the development of delirium, which was significant in any subgroup. CONCLUSION: Suvorexant should be recommended for the prevention of delirium in clinic.

More than a quarter century of the most prescribed sleeping pill: Systematic review of zolpidem use by older adults.

Zolpidem is widely used to treat insomnia of older adults despite that few randomized controlled studies were conducted in this group. We systematically reviewed the relevant literature on efficacy/effectiveness and safety of zolpidem use by elderly individuals in relevant databases completed with a manual search of key journals. Studies were required to include individuals aged ≥60 years under intervention with zolpidem compared to placebo or other hypnosedatives. Outcomes were either objectively- or subjectively-assessed improvements in specific sleep parameters and safety for clinical use. The 31 reports selected for review were mostly of low-quality. The evidence suggests that zolpidem is useful typically by reducing sleep latency and episodes of wake after sleep onset, and increasing total sleep time and sleep efficiency. Regarding safety and tolerability, analyses suggest a low risk of daytime sleepiness and of deleterious effects on memory or psychomotor performance, provided that recommended dosage and precautions are followed. Few retrospective studies associate zolpidem use with risk of falls, fractures, dementia, cancer, and stroke. Zolpidem appears effective at lower doses and for short-term treatment among the elderly. Rigorous, new clinical trials are warranted to further document the specific effects of zolpidem in older individuals.

Association of eszopiclone, zaleplon, or zolpidem with complex sleep behaviors resulting in serious injuries, including death.

PURPOSE: To identify and analyze postmarketing cases of complex sleep behaviors (CSBs) resulting in serious injuries, including death, associated with eszopiclone, zaleplon, or zolpidem (Z-drugs). METHODS: Retrospective analysis of the U.S. Food and Drug Administration (FDA) Adverse Event Reporting System (FAERS) from 16 December 1992 through 27 February 2018 and medical literature using PubMed and EMBASE. We used random sampling and descriptive statistics. RESULTS: We identified 66 cases that met inclusion and exclusion criteria, four of which were identified in the medical literature. Twenty cases reported death and 46 cases reported serious injuries in association with CSBs occurring after the use of a Z-drug. Fatal cases described events, such as carbon monoxide poisoning, drowning, falls, hypothermia, motor vehicle collisions, and apparent completed suicide. Nonfatal cases resulting in serious injuries described events, such as accidental overdoses, falls, gunshot wounds, hypothermia, third-degree burns, and self-injuries or suicide attempts. Twenty-two cases reported a previous episode of a CSB while taking a Z-drug prior to the event reported in this case series. CONCLUSIONS: The FAERS and medical literature cases support the need for increased awareness of the consequences that may occur because of CSBs associated with the use of Z-drugs. Therefore, to protect public health, regulatory actions were taken, including adding a Boxed Warning, a Contraindication in patients who have experienced a prior episode of a CSB with a Z-drug, and updating the existing Warnings and Precautions. An FDA Drug Safety Communication was also disseminated to alert healthcare professionals and the public of this potential risk.

"Risk-free rest and sleep:" Jornal do Médico (Portugal) and the thalidomide disaster, 1960-1962. / "Descansar e dormir sem riscos": o Jornal do Médico (Portugal) e o desastre da talidomida, 1960-1962.

This article analyzes the way the Porto-based journal Jornal do Médico reported on the thalidomide disaster. The pages of the publication are researched from the beginning of 1960 to the end of 1962 with the aim of identifying and discussing two interconnected questions: the delay in publishing news on the harmful effects of the drug, which was sold in the country under the brand name Softenon®, and the discursive construction of a lack of accountability on the part of physicians for the phenomenon of medication iatrogenesis.

O artigo analisa como o periódico Jornal do Médico, editado na cidade do Porto, em Portugal, divulgou o desastre da talidomida. A pesquisa percorreu as páginas da fonte desde o início de 1960 até o final de 1962. Aqui, objetivam-se apontar e discutir duas questões interligadas: a morosidade em publicar matérias sobre os efeitos deletérios do medicamento, vendido no país sob a denominação Softenon®, e a construção discursiva da isenção da responsabilidade do médico no fenômeno da iatrogenia medicamentosa.
