Comparative Bioavailability Study Between Ticagrelor and ASA Administered Individually or in Combination.

Comparative Study to Evaluate the Relative Bioavailability Between a Fixed-dose Combination Product of 90 mg Ticagrelor/100 mg Acetylsalicylic Acid vs Administration of the Reference Monotherapies in Healthy Subjects.

Study conducted to determine and compare the relative bioavailability of two solid oral formulations (reference versus test) of the non-fixed combination of Ticagrelor 90 mg (Brilinta by AstraZeneca S.A. de C.V.) + Acetylsalicylic Acid 100 mg (ASPIRINA JUNIOR by Bayer de México S.A. de C.V.) administered concomitantly versus the fixed-dose combination of Ticagrelor 90 mg / Acetylsalicylic Acid 100 mg manufactured by Laboratorios Silanes S.A. de C.V.

Prospective, longitudinal, open-label, single-dose per period, two treatments two periods, crossover, balanced, randomized study with a 7-day washout period in 20 plus 4 (24) healthy research subjects of both genders, under fasting conditions. In order to establish characterization of the pharmacokinetic parameters Cmax, Tmax, T1/2, Ke, (AUC 0-t) and the (AUC 0-~) when administered as a single dose of the non-fixed combination of Ticagrelor 90 mg (Brilinta by AstraZeneca S.A. de C.V.) + Acetylsalicylic Acid 100 mg (ASPIRINA JUNIOR by Bayer de México S.A. de C.V.) as a reference formulation and the fixed-dose combination of Ticagrelor 90 mg/ Acetylsalicylic Acid 100 mg as the test formulation manufactured by Laboratorios Silanes S.A. de C.V.
