- Design
- Systematic review and meta-analysis of RCTs and observational studies
- Population
- 19 studies; 183,595 adults with or without DORA use
- Primary outcome
- Falls and fractures
- Effect
- Falls OR 0.76 (0.56 to 1.04); RCTs OR 0.59 (0.35 to 0.98); fractures OR 1.05 (0.94 to 1.18)
A systematic review and meta-analysis in the Journal of the American Geriatrics Society, published on 26 September, pooled 19 studies — 10 randomised trials and 9 observational — with 183,595 participants, comparing dual orexin receptor antagonists (DORAs) for insomnia with no DORA.
Across all studies, DORAs did not increase falls (OR 0.76, 95% CI 0.56 to 1.04). In the randomised trials alone, falls were lower (OR 0.59, 0.35 to 0.98); the observational studies showed no clear difference (OR 0.88). Fractures were not increased (OR 1.05, 0.94 to 1.18).
Benzodiazepines and Z-drugs are well-established falls risks, so a hypnotic class without that signal would matter in older adults with insomnia who need medication. The authors are careful: events were few, the evidence did not reach the size needed for a firm conclusion, and data in older adults specifically were limited.
The practical change is in the second-line choice. When cognitive behavioural therapy for insomnia is not enough and a medicine is needed in an older person, a DORA is a reasonable option to discuss in preference to a benzodiazepine or Z-drug, with the same caution about next-day drowsiness. Availability and cost in India are uncertain.
- Offer cognitive behavioural therapy for insomnia first in older adults.
- When a hypnotic is needed, consider an orexin receptor antagonist in preference to a benzodiazepine or Z-drug.
- Warn about next-day drowsiness and review falls risk after starting any hypnotic.
- Review the need for the hypnotic regularly rather than continuing indefinitely.
- Check local availability and cost; status in India is uncertain.
Why it matters
It offers a hypnotic option that, on current evidence, does not carry the falls signal of older sedatives.
Don't overread it
Few events and limited data in older adults; this suggests, but does not prove, that DORAs are safe for falls.
The statistics, in plain English
The overall falls OR of 0.76 has an interval crossing 1, so no clear effect either way. The trial-only OR of 0.59 excludes 1 but rests on few events. The review did not reach its optimal information size, the number of events needed for a firm conclusion.
