Indication: | Rivaroxaban is indicated for the prevention of venous thromboembolic events (VTE) in patients who have undergone total hips replacements and total knee replacement surgery. Due to a lack of safety studies, it is not recommended for use in those under 18 years old. Its use is also not recommended in those with severe renal impairment (<30mL/min). |

Pharmacology: |
Rivaroxaban is an anticoagulant which binds directly to factor Xa. Thereafter, it effectively blocks the amplification of the coagulation cascade, preventing the formation of thrombus. Rivaroxaban is a unqiue anticoagulant for two reasons. First of all, it is does not involve antithrombin III (ATIII) to exert its anticoagulant effects. Secondly, it...

Mechanism of Action: |
Rivaroxaban competitively inhibits free and clot bound factor Xa. Factor Xa is needed to activate prothrombin (factor II) to thrombin (factor IIa). Thrombin is a serine protease that is required to activate fibrinogen to fibrin, which is the loose meshwork that completes the clotting process. Since one molecule of factor Xa can generate more than 1...

Absorption: | Following oral administration, the absolute bioavailability is about 100% |
Protein binding: | Plasma protein binding is about 92% to 95% |
Biotransformation: | Approximately 2/3 of the dose is metabolized. It is metabolized by CYP3A4, CYP2J2 and CYP-independant mechanisms |
Route of elimination: | About 1/3 of the administered dose is excreted unchanged via the kidneys, 1/3 is metabolized to inactive metabolites and then excreted by the kidneys and 1/3 is metabolized to inactive metabolites and excreted fecally. |
Half Life: | The terminal half life is 5-9 hours in young individuals and 11-13 hours in the elderly. |
Clearance: | Systemic clearance is about 10L/h, so rivaroxaban is considered a drug with low clearance. Renal clearance is about 3-4L/h. |
Toxicity: | Excessive bleeding. Overdosages should be treated using activated charcoal and supportive measures such as mechanical compression and hemodynamic support. If bleeding is not controlled, the following procoagulants can be administered: activated prothrombin complex concentrate, prothrombin complex concentrate and recombinant factor VIIa. There is also a higher chance of post procedural hemorrhage compared to enoxaparin (1.55% vs. 1.39% respectively). |
