Pharmacodynamic Study of Parallel Groups Comparing the Effect of rivaroxaban 20 Mg (Laboratorios Leti, S.A.v.) vs rivaroxaban 20 Mg (Bayer Laboratories) on Prothrombin Time

Background: The prevalence of both atrial fibrillation (FA) and diabetes mellitus (DM) is increasing and they often occur together and constitute a high risk of thrombosis. rivaroxaban is a Factor Xa inhibitor with a rapid onset and disappearance of action after oral administration;it acts by inhibiting the active form of the coagulation factor. in order to reflect the effect of the action of rivaroxaban, we used the prothrombin time (PT);however, it′s not the most accurate, but it is the one available in our community. Methods: This was a prospective, randomized, analyst-blinded, parallel group clinical study to verify the efficacy of rivaroxaban Leti 20 mg (rL) (12 volunteers vs rivaroxaban Bayer 20 mg (rB) (13 volunteers). The variables were determination of PT and Partial Thromboplastin Time (aPTT) at baseline and at 24, 48 and 72 hours after administering a daily dose of 20 mg for three days. The determination was carried out with the iDG method (integrated Diagnostics Group Sanzay Corporation) with an international Sensitivity index (iSi) of 1.17 PT and aPTT were taken before the first dose, and then, every day during the next 3 days, three hours after the ingestion of their daily dose at 7 am. results: The 25 healthy volunteers were similar in age, BMi, and SBP/DBP level with a greater number of men in the Bayer group. The efficacy of rivaroxaban was similar in both groups with prolongation of PTT to the 2nd day of treatment with PT, and percentage changes from baseline (14.46 ± 0.97 for rB vs 14.17 ± 0.94 rL p: 0.45), PTT results and percentage changes from the base (rB: 34 ± 4.53 rL: 33.46 ± 2.82). The safety of rivaroxaban was good in both groups with no serious adverse ev.n.s. The equivalence in the logarithmically transformed PT result (ln) on day two, Mean and Ci (90%) 99.2 (94.4-104) and 100 (99.5-100.8);neither the means nor the 90% confidence intervals of the PT variable transformed logarithmically to ensure its normality, were far from the 80%-125%

in this paper, diffusion of the contaminants skew discharged by 2 different angles 60°90°and its flow field have been studied. The n-S equations and diffusion equations are solved by SiMPLEC method, u, v and concention difference equations are solved by LSOr, and p' solved by direct methed and GMrES(m) ahernately. Discontinuous jet are also considered. numerical results indicate that skew aide discharge is the prior alternative in a navigable when pollution problem is of less importance.
