This study is designed to assess bioequivalence between one test and one reference formulation used for temporary relief of pain. The results will help decide if the new medicine is likely to provide pain relief similar to the product being sold.
The study is a single dose, randomized, two-way crossover study in 32 healthy male and female volunteers, minimum of 14 of each gender. Two doses of study medication will be given as single doses on two separate treatment visits. A washout of at least 48 hours will separate the treatment visits. Each visit will include an overnight fast at the clinic and 19 blood samples drawn for pharmacokinetic analyses. Tolerability of the treatments will be evaluated in terms of reported and observed adverse events (AE).

Cmax
Maximum observed plasma concentration (Cmax), is the maximum (peak) concentration (amount of drug) measured in blood plasma after a dose administration.
Time frame: During 12 hours post-dose
AUCt
Area under the plasma concentration-vs.-time curve from start of drug administration until last measured concentration (AUCt), is a measure of how much of the drug reaches the bloodstream during the sampling period.
Time frame: During 12 hours post-dose
AUC∞
Area under the plasma concentration-vs.-time curve from start of drug administration and extrapolated to infinity (AUC∞), is a measure of how much of the drug ever reaches the bloodstream.
Time frame: During 12 hours post-dose
tmax
The time at which maximum concentration is reached (tmax)
Time frame: During 12 hours post-dose
Terminal Elimination Rate Constant (λz)
The terminal elimination rate constant (λz) describes the rate at which a drug is eliminated from the body.
Time frame: During 12 hours post-dose
t½
Terminal half-life (t½) is the time required for the plasma concentration (as well as the amount of drug in the body) to fall by one-half.
Time frame: During 12 hours post-dose
Mean Residence Time (MRT)
Mean residence time (MRT) is the mean time a drug molecule resides in the body.
Time frame: During 12 hours post-dose
