简要总结
This study is designed to assess bioequivalence between one test and two reference formulations used for treatment of headaches and temporary relief of pain.
详细描述
The study is a single dose, randomized, three-way crossover study in 30 healthy subjects, with equal numbers of males and females (minimum of 13 of either gender). Drop-outs will not be replaced. The three doses of medication given in the study (a single dose in each of the three study periods) will each be separated by a washout period of at least 7 calendar days. In each study period, eighteen (18) blood samples for pharmacokinetic analysis will be taken over 12 hours. Blood samples will be centrifuged and concentrations of ibuprofen (R-enantiomer and S-enantiomer) in plasma will be measured using a validated chromatographic assay. Pharmacokinetic parameters will be calculated from plasma concentration data [R-enantiomer, S-enantiomer and total (sum of both enantiomers)]. The rate and extent of absorption of the formulations will be compared.

结局指标
主要结局
Maximum Observed Plasma Concentration
时间窗: During 12 hours post-dose
Maximum Observed Plasma Concentration (Cmax), which is the maximum (peak) concentration (amount of drug) measurable in blood plasma after a dose is administered, measured in nanograms/milliliter (ng/mL)
Bioavailability [AUC(0-t)]
时间窗: During 12 hours post-dose
Bioavailability \[AUC(0-t)\] is a measure of how much of the drug reaches the person's bloodstream within a given period of time for the body to use. The extent of product bioavailability is estimated by the area under the blood concentration vs time curve. The Area Under the Curve (AUC) is calculated by plotting the drug's blood levels on a graph at different times during the set period. The area under this curve reflects the amount of drug exposure in the set time period, calculated as hour \* nanograms (ng) per milliliter (mL).
次要结局
- Bioavailability Extrapolated to Infinity [AUC (0-∞)](12 hours post-dose)
- Time of Maximum Concentration(During 12 hours post-dose)
- Terminal Elimination Rate Constant(During 12 hours post-dose)
- Terminal Phase Plasma Half-Life(During 12 hours post-dose)
