Each outcome the trial registered, primary first, in ClinicalTrials.gov's words.
| List | Outcome | Time frame | Description |
|---|---|---|---|
| Primary | Growth Hormone Secretion | During only one sleep night immediately after a single gabapentin or placebo dose at bedtime. | Every 20 minutes after admission to the laboratory, blood samples (2.5 mL) for GH measurement will be collected (between 20:00 - or 2 hours before lights off - and 06:00). |
| Primary | IGF-1 | Immediately after the sleep night in that gabapentin or placebo dose were given at bedtime. | It will be included in the analysis of the last sample collected for GH, testosterone and cortisol measurements at 06:00. |
| Secondary | Total testosterone | During only one sleep night immediately after a single gabapentin or placebo dose at bedtime. | Every 20 minutes after admission to the laboratory, blood samples (2.5 mL) for free and total testosterone measurements will be collected (between 20:00 - or 2 hours before lights off - and 06:00). |
| Secondary | Free testosterone | During only one sleep night immediately after a single gabapentin or placebo dose at bedtime. | Every 20 minutes after admission to the laboratory, blood samples (2.5 mL) for free and total testosterone measurements will be collected (between 20:00 - or 2 hours before lights off - and 06:00). |
| Secondary | Cortisol | During only one sleep night immediately after a single gabapentin or placebo dose at bedtime. | Every 20 minutes after admission to the laboratory, blood samples (2.5 mL) for cortisol measurement will be collected (between 20:00 - or 2 hours before lights off - and 06:00). |
| Secondary | Apnea-Hypopnea Index during sleep | During only one sleep night immediately after a single gabapentin or placebo dose at bedtime. a single gabapentin or placebo dose at bedtime. | Sedative drugs may increase asymptomatic airway collapsability during sleep mainly in older individuals |
