Insomnia is a prevalent and challenging issue in older adults, often impacting daytime functioning and increasing the risk of other health concerns. Past generations of sleep aids, such as benzodiazepines and certain non-benzodiazepine hypnotics (Z-drugs), have long been associated with safety risks for seniors, including daytime sedation, cognitive impairment, and a higher risk of falls and fractures. This led to a critical need for safer, more effective treatments. The answer for many has arrived in the form of dual orexin receptor antagonists (DORAs), which target the wakefulness system rather than generally suppressing the central nervous system.
Understanding Dual Orexin Receptor Antagonists (DORAs)
DORAs represent a paradigm shift in insomnia pharmacotherapy. Instead of broadly sedating the brain, they work by blocking the activity of orexin, a neuropeptide that promotes wakefulness. By inhibiting orexin, these medications essentially turn down the brain's "wake-up" signal, allowing for a more natural transition to sleep. This targeted approach is believed to result in fewer side effects associated with central nervous system (CNS) depression compared to older sedative-hypnotics, making them a potentially safer option for older adults.
Daridorexant (Quviviq)
Daridorexant, marketed as Quviviq, is one of the newest DORAs approved by the FDA for treating insomnia in adults. Clinical studies, including specific evaluations in elderly subjects (ages 65-85), have demonstrated its effectiveness in reducing both sleep latency (time to fall asleep) and wake after sleep onset (WASO). A notable feature of daridorexant is its relatively short half-life of approximately 8 hours, which, in theory, may minimize next-day residual effects compared to other DORAs.
However, potential side effects, though often mild, can include fatigue, headache, dizziness, and nausea. For older adults, there is a higher risk of falls associated with increased somnolence, a warning that applies to many sleep-promoting drugs.
Lemborexant (Dayvigo)
Lemborexant, sold under the brand name Dayvigo, has also been shown to be effective in older adults (≥ 65 years) for both sleep onset and maintenance. Studies found that lemborexant significantly improved subjective sleep-onset latency and sleep efficiency over 12 months of nightly treatment. It also demonstrated less risk of postural instability and balance impairment compared to zolpidem in older adults.
Common side effects include somnolence, with a dose-dependent increase in occurrence. Given its longer half-life (17-19 hours), next-day residual effects remain a theoretical concern, though clinical data suggests minimal impairment with appropriate consideration for individual needs.
Suvorexant (Belsomra)
Suvorexant, known as Belsomra, was the first DORA to be approved and has been available since 2014. Studies confirm its effectiveness in improving sleep onset and maintenance for elderly individuals with insomnia, with results persisting over a one-year period. It is also approved for treating sleep disorders in people with Alzheimer's disease.
Common side effects include headache and, most notably, next-day drowsiness (somnolence). The half-life is around 12 hours, which contributes to the risk of daytime impairment and requires careful monitoring. Older adults may also experience a higher risk of complications from next-day sedation.
Comparing New Dual Orexin Receptor Antagonists for the Elderly
| Feature | Daridorexant (Quviviq) | Lemborexant (Dayvigo) | Suvorexant (Belsomra) |
|---|---|---|---|
| Approval | Approved for adults since 2022. | Approved for adults since 2019. | Approved for adults since 2014. |
| Mechanism | Dual orexin receptor antagonist (DORA). | Dual orexin receptor antagonist (DORA). | Dual orexin receptor antagonist (DORA). |
| Half-Life | ~8 hours, shortest of the DORAs. | 17–19 hours. | ~12 hours. |
| Key Elderly Benefit | Potentially less next-day impairment due to shorter half-life. | Long-term efficacy with less postural instability compared to some older drugs. | Long-term efficacy, also approved for insomnia in Alzheimer's disease. |
| Side Effects | Fatigue, headache, dizziness, nausea. | Somnolence, headache, fatigue. | Next-day somnolence, headache, dizziness. |
| Elderly Caution | Monitor for falls and daytime impairment. | Use caution due to potential for somnolence and fall risk. | Monitor for next-day drowsiness risk. |
Important Considerations for Seniors
While DORAs offer a new path for insomnia treatment, a comprehensive approach is crucial for older adults. Non-pharmacological treatments are typically recommended as the first-line intervention.
- Cognitive Behavioral Therapy for Insomnia (CBT-I): This is considered the "gold standard" treatment and is proven effective in older adults. It addresses the root causes of insomnia through techniques like sleep restriction, stimulus control, and relaxation training.
- Medication Interaction: Given that many older adults take multiple medications, potential drug interactions are a significant concern. All DORAs are metabolized by CYP3A4 enzymes, and drug interactions can alter their effects. It is crucial to discuss all medications and supplements with a healthcare provider before starting a DORA.
- Daytime Impairment: Even with newer drugs, the risk of next-day somnolence, fatigue, and impaired driving remains. This is particularly dangerous for older adults, increasing the risk of falls and accidents. Patients should be cautioned about activities requiring mental alertness after taking these medications.
- Complex Sleep Behaviors: Rarely, hypnotics can induce complex sleep behaviors like sleep-driving or sleepwalking. Patients and their families should be vigilant for these occurrences. If such behaviors occur, contact a healthcare provider immediately.
- Co-morbid Conditions: Insomnia can be a symptom of an underlying medical or psychiatric condition. A careful evaluation is necessary to rule out or address other health issues before initiating treatment for insomnia. Addressing underlying conditions may resolve sleep difficulties without the need for medication.
Beyond Medication: A Holistic Approach to Sleep
For older adults, addressing insomnia goes beyond a single prescription. Combining pharmacological treatment with behavioral and lifestyle changes often yields the best results. Good sleep hygiene, including maintaining a consistent sleep schedule and creating a quiet, cool, and dark bedroom environment, is fundamental. Regular exercise, mindful of the timing, can also improve sleep quality. Avoiding late-day caffeine and alcohol is also recommended. In all cases, a personalized approach guided by a healthcare provider is the most effective strategy.
Conclusion
The question of what is the new sleeping pill for the elderly? points to a promising new class of medications known as dual orexin receptor antagonists (DORAs). Daridorexant, Lemborexant, and Suvorexant offer a more targeted way to address insomnia compared to older, less safe alternatives. However, they are not without risk, and close monitoring for side effects like daytime somnolence and increased fall risk is essential, especially in the geriatric population. For long-term management, non-pharmacological strategies like CBT-I remain the preferred first-line treatment and should be considered alongside any medication plan. Ultimately, the right path to better sleep for an older adult involves a careful assessment of risks, benefits, and a focus on both pharmaceutical and behavioral interventions.
