Insights
Multiple hypnotic prescriptions are common, affecting 10% of patients. This practice is linked to increased rates of mood disorders, anxiety, chronic pain, and sleep issues, suggesting a need for personalized treatment approaches.
Area of Science:
- Sleep Medicine
- Clinical Pharmacology
- Psychiatry
Background:
- Multiple hypnotic prescriptions are frequently observed in clinical practice.
- Understanding the characteristics and associations of multiple hypnotic prescriptions is crucial for patient care.
Purpose of the Study:
- To investigate the prevalence of multiple hypnotic prescriptions.
- To identify clinical and demographic factors associated with hypnotic use.
- To explore the association between multiple hypnotic prescriptions and various diagnoses using a phenome-wide association study (PheWAS).
Main Methods:
- Analysis of electronic health records (EHR) from 52,940 adult participants in the Mayo Clinic Biobank.
- Comparison of demographic and clinical characteristics between participants with no, single, or multiple (≥ 2) hypnotic prescriptions.
- Phenotype-based, phenome-wide association study (PheWAS) to identify diagnoses associated with multiple hypnotic prescriptions, adjusting for confounders.
Main Results:
- 33% of participants received at least one hypnotic, and 10% received multiple hypnotics.
- Hypnotic users were more likely to be older, female, White, with longer EHRs and more diagnoses.
- Multiple hypnotic prescriptions were associated with younger age, female sex, longer EHRs, more diagnoses, and higher rates of mood disorders, anxiety disorders, suicidal ideation, restless legs syndrome, and chronic pain.
Conclusions:
- Multiple hypnotic prescriptions are common and linked to a higher incidence of psychiatric, chronic pain, and sleep-related movement disorders.
- These findings highlight the need for further research into potential genetic factors to enable personalized insomnia treatment strategies.
Study Objectives:
We examined the prevalence of multiple hypnotic prescriptions and its association with clinical and demographic characteristics from the electronic health record (EHR) in the Mayo Clinic Biobank.
Methods:
Adult participants enrolled in the Mayo Clinic Biobank with an EHR number of ≥ 1 year were included (n = 52,940). Clinical and demographic characteristics were compared between participants who were and were not prescribed any hypnotic approved for insomnia by the US Food and Drug Administration and/or trazodone and in those prescribed a single vs multiple (≥ 2) hypnotics. A phenotype-based, phenome-wide association study (PheWAS) examining associations between hypnotic prescriptions and diagnoses across the EHR was performed adjusting for demographic and other confounders.
Results:
A total of 17,662 (33%) participants were prescribed at least 1 hypnotic and 5,331 (10%) received ≥ 2 hypnotics. Participants who were prescribed a hypnotic were more likely to be older, female, White, with a longer EHR, and a greater number of diagnostic codes (all P < .001). Those with multiple hypnotic prescriptions were more likely to be younger, female, with a longer EHR, and a greater number of diagnostic codes (all P < .001) compared with those prescribed a single hypnotic. The PheWAS revealed that participants with multiple hypnotic prescriptions had higher rates of mood disorders, anxiety disorders, suicidal ideation, restless legs syndrome, and chronic pain (all P < 1 e-10).
Conclusions:
Receiving multiple hypnotic prescriptions is common and associated with a greater prevalence of psychiatric, chronic pain, and sleep-related movement disorders. Future studies should examine potential genetic associations with multiple hypnotic prescriptions to personalize treatments for chronic insomnia.

Sedatives and Hypnotics Drugs: Miscellaneous Agents
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: Overview
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...
