- Schneider-Helmert 1986
- 16 weeks
- Chronic insomnia patients (n=14)
- Hepatic panel, renal function, CBC, thyroid markers, subjective sleep quality
- Transient drowsiness (2 patients), mild headache (1 patient). All resolved spontaneously
- Receptor density changes, HPA axis diurnal rhythm, withdrawal symptoms, autoimmune markers
- Iyer 1977
- 21 days
- Healthy volunteers (n=15)
- Liver enzymes, kidney function, blood pressure, subjective tolerance
- Mild injection site tenderness (3 participants)
- Long-term receptor adaptation, immune function, endocrine feedback loops
- Kastin 1981
- 8 weeks
- Chronic pain patients (n=22)
- Hepatic function, renal markers, pain scores, sedation scales
- No significant adverse events vs placebo
- Neuroendocrine axis function, receptor desensitisation, metabolic parameters
- Monnier 1977
- 5 days
- Acute sleep deprivation model (n=8)
- EEG delta wave density, cortisol, subjective alertness
- None reported
- Chronic receptor changes, tolerance development, rebound phenomena
- The pattern is consistent. Short trials, narrow safety panels, zero long-term follow-up. What's missing isn't just duration. It's the biological markers that would detect subtle, progressive dysfunction.
