Brief Summary
The purpose of this study is to help scientist better understand the effect of a 12-week single daily evening dose of ramelteon (Rozerem ©), a drug that has been approved by the U. S. Food and Drug Administration (FDA) for the treatment of insomnia (trouble falling asleep or staying asleep). The study will measure levels of inflammation, fasting insulin and fasting glucose (sugar) in subjects who are taking either ramelteon (8 mg) or placebo.

Outcome Measures
Primary Outcomes (7)
Sleep Onset Latency (SOL) as Measured by Self Report (Sleep Diary)
The average of a week of sleep onset latency data from the sleep diary filled out in the morning by the participating subjects. Sleep latency is defined as the length of time it takes from lying down for the night until sleep onset.
Day 89-90
Mean Latency to Persistent Sleep (LPS) Via Polysomnography
Elapsed time from the beginning of the Polysomnography recording to the onset of the first 20 minutes of continuous sleep was measured.
Day 89-90
Change in Metabolic Syndrome (MetSyn)
Baseline, Day 30, Day 60, Day 89-90
Sleep Onset Latency (SOL) as Measured by Pittsburgh Sleep Qualtiy Index (PSQI)
Subjects completed component 2 of the PSQI questionnaire. Component 2 asks questions about sleep latency and is scored on a scale from 0 (better) to 3 (worse).

Study Arms (2)
ramelteon
ACTIVE COMPARATORSubjects will take ramelteon 8mg one time daily 30 minutes before bedtime with approximately 8 ounces of water. Subjects have a 2 out of 3 chance of receiving ramelteon.
placebo
PLACEBO COMPARATOR15 subjects will be randomized to receive the placebo
Interventions
Eligibility Criteria
You may qualify if:
- At screening visit:
- aged 18-65
- nonsmokers
- for women: oral contraceptive (OC) or hormone replacement therapy (HRT) nonusers
- ages 18-65 inclusive;
- PSQI-Component 2 (sleep latency) score of greater than 1;
- non-smoker (e.g., less than 20 cigarettes in the past 5 years);
- habitual bedtime between 8:30 pm and midnight
- For premenopausal women:
- regular menstrual cycles determined by Framingham Study criteria;
- not pregnant and no history of oral contraceptive (OC) usage in last 6-months.
- For postmenopausal women:
- no recent (\< 6 months) use of Hormone Replacement Therapy (HRT)
- no surgical menopause
You may not qualify if:
- positive urine drug screen
- Potential subjects with hypersensitivity to ramelteon or any components of the formulation will be excluded from participation.
- Given that ramelteon should not be used by individuals with severe hepatic impairment, or in patients in combination with fluvoxamine, individuals who report liver problem or use of fluvox will be excluded.
- use of rifampin (Rifadin ©); ketoconazole (Nizora ©l); or fluconazole (Diflucan ©).
- Ramelteon has not been studied in children or adolescents, and the effects in these populations are unknown, thus only individuals above 18 years will participate.
