Brief summary: Study carried out in the Clinical and Analytical Unit of the Department of Pharmacology and Toxicology of the Faculty of Medicine of the Autonomous University of Nuevo León, with the objective of comparing the bioavailability (Cmax, AUC) of an oral formulation containing Etoricoxib 90 mg / Tramadol 50 mg in combination with that of two oral formulations, Etoricoxib 90 mg or Tramadol 50 mg, administered as a single dose, in healthy subjects under fasting conditions.

Detailed description: The study design was a crossover, 3 x 6 x 3, open-label, prospective and longitudinal, truncated, single-dose combination of Etoricoxib 90 mg / Tramadol 50 mg administered orally versus each component administered individually, with three treatments, three periods. , six sequences with an elimination period (washout) of 14 days and with a total of 42 healthy subjects, of both genders, under fasting conditions. Among the objectives were the characterization of the pharmacokinetic parameters, Cmax, AUC 0-72, Tmax, Ke and T1/2 of Etoricoxib and Tramadol after oral administration in a single dose, in combination: sachet with granules equivalent to Etoricoxib 90 mg/ Tramadol 50 mg manufactured by Laboratorios Silanes, S.A. of C.V. versus each component administered individually: Etoricoxib 90 mg tablet (Arcoxia®) manufactured by Schering Plough S.A de C.V. and Tramadol 50 mg capsule (Tradol®) made by Grunenthal GMBH (private company).
