The structure of apixaban, before adjusting the moiety's for maximum potency. Apixaban. The 13F moiety intermediate before apixaban was fully developed. During the SAR development of apixaban there were three groups that needed to be tested to attain maximum potency and bioavailability.
Apixaban is a highly selective, orally bioavailable, and reversible direct inhibitor of free and clot-bound factor Xa. Factor Xa catalyzes the conversion of prothrombin to thrombin, the final enzyme in the coagulation cascade that is responsible for fibrin clot formation. [ 25 ]
In these cases, clearance is almost synonymous with renal clearance or renal plasma clearance. Each substance has a specific clearance that depends on how the substance is handled by the nephron. Clearance is a function of 1) glomerular filtration, 2) secretion from the peritubular capillaries to the nephron, and 3) reabsorption from the ...
Clearance is therefore expressed as the plasma volume totally free of the drug per unit of time, and it is measured in units of volume per units of time. Clearance can be determined on an overall, organism level («systemic clearance») or at an organ level (hepatic clearance, renal clearance etc.). The equation that describes this concept is:

[14] [15] Renal clearance and degradation account for the most part for the systemic clearance of desulfatohirudins and there is accumulation of the drug in patients with chronic kidney disease. These drugs should not be used in patients with impaired renal function, since there is no specific antidote available to reverse the effects. [14]
