Outcome Measures
Primary Outcomes (8)
Maximum Observed Serum Concentration (Cmax)
Maximum observed serum concentration (Cmax) is the peak serum concentration of ramelteon and its metabolite (M-II) after administration, obtained directly from the serum concentration-time curve.
Day 1: predose (within 1 hour prior to dose) and at 0.5, 1, 2, 3, 4, 6, 8, 12, and 16 hours post-dose.
Time to Reach Maximum Serum Concentration (Tmax)
Tmax: Time to reach the maximum serum concentration (Cmax) of ramelteon and its metabolite M-II, equal to time (hours) to Cmax.
Day 1: predose (within 1 hour prior to dose) and at 0.5, 1, 2, 3, 4, 6, 8, 12, and 16 hours post-dose.
Area Under the Serum Concentration-time Curve From Time 0 to Time of the Last Quantifiable Concentration (AUC[0-tlqc])
Area under the serum concentration-time curve from time 0 to time of last quantifiable concentration (tlqc) of ramelteon and its metabolite M-II, calculated using the linear trapezoidal rule.
Day 1: predose (within 1 hour prior to dose) and at 0.5, 1, 2, 3, 4, 6, 8, 12, and 16 hours post-dose.
Area Under the Serum Concentration-time Curve From Time 0 to Infinity (AUC[0-inf])
Area under the serum concentration-time curve from time zero extrapolated to infinity for ramelteon and its metabolite M-II. The terminal area from the last quantifiable concentration (lqc) to infinity is calculated by approximation: lqc / terminal elimination rate constant (λz).
Day 1: predose (within 1 hour prior to dose) and at 0.5, 1, 2, 3, 4, 6, 8, 12, and 16 hours post-dose.
Apparent Clearance After Oral Administration (CL/F)
Apparent oral clearance of drug from the serum calculated as: CL/F = Dose / Area under the serum concentration-time curve from time 0 extrapolated to infinity (AUC\[0-inf\]).
Day 1: predose (within 1 hour prior to dose) and at 0.5, 1, 2, 3, 4, 6, 8, 12, and 16 hours post-dose.
Terminal Elimination Rate Constant (λz)
The rate at which ramelteon and its metabolite M-II are eliminated from the body, calculated as the negative of the slope of the log-linear regression of the natural logarithm concentration-time curve during the terminal phase.
Day 1: predose (within 1 hour prior to dose) and at 0.5, 1, 2, 3, 4, 6, 8, 12, and 16 hours post-dose.
Terminal Elimination Half-life (T1/2)
Terminal phase elimination half-life (T1/2) for ramelteon and its metabolite M-II is the time required for half of the drug to be eliminated from the serum, calculated as T1/2 = natural logarithm of 2 (ln\[2\]) / Terminal elimination rate constant (λz).
Day 1: predose (within 1 hour prior to dose) and at 0.5, 1, 2, 3, 4, 6, 8, 12, and 16 hours post-dose.
Apparent Volume of Distribution (Vz/F)
Vz/F is the distribution of a drug between plasma and the rest of the body following oral administration, calculated as Vz/F = Apparent oral clearance (CL/F) / Terminal elimination rate constant (λz).
Day 1: predose (within 1 hour prior to dose) and at 0.5, 1, 2, 3, 4, 6, 8, 12, and 16 hours post-dose.

Eligibility Criteria
You may qualify if:
