Rivaroxaban (Xarelto, BAY 59-7939) is oral direct factor Xa inhibitor with an IC50 value of 2.1nM. Rivaroxaban (Xarelto,BAY 59-7939) inhibits endogenous FXa more potently in human and rabbit plasma (IC50 = 21 nM) than in rat plasma (IC50 = 290 nM).Rivaroxaban (Xarelto,BAY 59-7939) also shows a similar affinity to purified human and rabbit FXa (IC50=0.7 nM and 0.8 nM, respectively), but a lesser potency against purified rat FXa (IC50 3.4 nM).

| Preparation method | Calculation of the Apparent Permeability Coefficient Values for Rivaroxaban. The apparent permeability coefficient (Papp) was calculated using eq. 1:where Papp is the apparent permeability, Vr is the volume of medium in the receiver chamber, C0 is the concentration of the test drug in the donor chamber at t = 0 h, S is the surface area of the monolayer, C2 is the concentration of the test drug in the acceptor chamber after 2 h of incubation, and t is the incubation time. For reference compounds, peak heights were used instead of concentrations.where Papp(B–A) and Papp(A–B) represent the apparent permeability of the test compound from the basolateral to apical and apical to basolateral sides of the cellular monolayer, respectively. The S.D. for the efflux ratio was calculated using eq. 3:where SD Papp(B–A) and SD Papp(A–B) represent the standard deviations of the apparent permeability of test compound from the basolateral to apical and apical to basolateral side of the cellular monolayer, respectively. |
