Abstract

Purpose:

Benzodiazepine receptor agonists (BZRAs), including benzodiazepines (BZDs) and Z drugs, are widely prescribed for anxiety and sleep. Therefore, issues of tolerance, dependence and adverse effects are of concern. Recent studies suggested a potential link between BZRAs and hearing problems. However, the actual relationship was still unclear. Accordingly, this study aims to investigate the actual association between BZRA use and risk of sudden sensorineural hearing loss (SSNHL) using population data.

Patients And Methods:

This study used the Taiwan Longitudinal Health Insurance Database. 137,277 BZRA users and 1,328,554 nonusers were identified for relevant analyses. We used cohort design with inverse-probability treatment weighting (IPTW) strategy to balance the baseline differences of demographics and comorbidities between two groups. The 5-year incidence of SSNHL was followed. Cox proportional-hazard regression analyses were used to estimate the hazard ratios (HRs).

Results:

BZRA users showed an increased 5-year SSNHL risk (adjusted HR: 1.244) after weighting. Subgroup and sensitivity analyses produced consistent results. Notably, SSNHL risk was higher among young BZRA users (adjusted HR: 1.397). BZRA users had the highest SSNHL risk in the first year (adjusted HR: 2.037) after IPTW.

Conclusion:

BZRA use elevated the risk of SSNHL, particularly in young adults and in the first year. This emphasises the importance for physicians and policymakers should be aware of the potential hearing difficulties among BZRA users and take necessary examinations.

Sedatives and Hypnotics: Overview

Sedatives and Hypnotics: Overview

Sedatives are drugs that alleviate anxiety, while hypnotics induce sleep. Both classes of medication suppress neuronal activity, leading to a calming effect for sedatives and facilitating sleep for hypnotics.
Sedative-hypnotics are categorized into barbiturates, benzodiazepines (BZDs), and non-benzodiazepines or Z-drugs. These drugs work by suppressing central nervous system activity, and this suppression is dose-dependent. Older sedative medications, like barbiturates, follow a linear curve in...

CNS Depressants: Barbiturates and Benzodiazepines

CNS Depressants: Barbiturates and Benzodiazepines

CNS depressants include drugs from the category of barbiturates and benzodiazepines. They are valuable medications for managing anxiety disorders and insomnia. Barbiturates, once used to induce and maintain sleep, have been replaced mainly by benzodiazepines due to barbiturate's toxicity, tolerance, and overdose risks. They interact with GABAA receptors, leading to sedation at low doses and potentially coma and death at higher doses. Phenobarbital, a long-acting barbiturate, possesses...

Sedatives and Hypnotics Drugs: Barbiturates

Sedatives and Hypnotics Drugs: Barbiturates

Sedatives and hypnotics encompass a drug class that acts on the central nervous system (CNS) to alleviate anxiety, promote relaxation and induce sleep.These drugs function by amplifying the actions of the neurotransmitter γ-aminobutyric acid (GABA), resulting in reduced neuronal activity. Barbiturates, a subset of sedatives and hypnotics first synthesized in the late 1800s, are categorized into ultra-short, short, intermediate, and long-acting groups based on their duration of effect. A...

Sedatives and Hypnotics Drugs: Miscellaneous Agents

Sedatives and Hypnotics Drugs: Miscellaneous Agents

Sedatives and hypnotics encompass a wide range of substances, each with its unique mechanism of action, uses, and potential adverse effects.
Melatonin congeners like ramelteon (Rozerem) and tasimelteon (Hetlioz) selectively bind to melatonin receptors (MT1 and MT2) and thus mimic the actions of melatonin, a hormone that regulates sleep-wake cycles. Tasimelteon is primarily used for non-24-hour sleep-wake disorder, common in blind patients. They are also used to treat conditions like insomnia...

Sedatives and Hypnotics Drugs: Benzodiazepines

Sedatives and Hypnotics Drugs: Benzodiazepines

Benzodiazepines have both sedative and hypnotic properties. They include compounds such as diazepam (Valium) and alprazolam (Xanax). Structurally, their cores are similar, consisting of the fusion of a benzene ring and a diazepine ring, but they share a common mechanism of action in the central nervous system (CNS).
Benzodiazepines work by enhancing the effects of the inhibitory neurotransmitter GABA. They bind to the GABAA receptor, increasing its affinity for GABA, which opens chloride...

Depressants

Depressants

Depressant drugs, including alcohol and sedative-hypnotics, diminish central nervous system activity by enhancing the action of gamma-aminobutyric acid (GABA), a neurotransmitter that reduces brain activity and promotes relaxation. These substances can have various therapeutic uses but also pose significant risks, especially when misused or combined.
Alcohol is a common depressant that can induce a sense of relaxation and reduced inhibition at low doses. Contrary to its occasional...
