Rivaflo
Rivaflo Uses, Dosage, Side Effects, Food Interaction and all others data.
Rivaflo is a highly selective direct factor Xa inhibitor. Inhibition of factor Xa interrupts the intrinsic and extrinsic pathway of the blood coagulation cascade, inhibits thrombin formation. Rivaflo does not inhibit thrombin (activated factor II) and no effects on platelets have been demonstrated.
Rivaflo is an anticoagulant which binds directly to factor Xa. Thereafter, it effectively blocks the amplification of the coagulation cascade, preventing the formation of thrombus. Rivaflo 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 is an oral agent whereas the widely used unfractionated heparin and low molecular weight heparins are for parenteral use only. Although the activated partial thromboplastin time (aPTT) and HepTest (a test developed to assay low molecular weight heparins) are prolonged in a dose-dependant manner, neither test is recommended for the assessment of the pharmacodynamic effects of rivaroxaban. Anti-Xa activity and inhibition of anti-Xa activity monitoring is also not recommended despite being influenced by rivaroxaban.

Uses
Rivaflo 2.5 mg:
- For the prevention of atherothrombotic events in adult patients after an Acute Coronary Syndrome (ACS) with elevated cardiac biomarkers (Troponin or CK-MB). It is co-administered with Aspirin alone or with Aspirin plus Clopidogrel orTidopidine.
Rivaflo 10-20 mg:
- To reduce the risk of stroke and systemic embolism in patients with nonvalvular atrial fibrillation
- Deep vein thrombosis (DVT) & pulmonary embolism (PE) and reduction in the risk of recurrence of DVT and of PE
- For the prophylaxis of DVT, which may lead to PE in patients undergoing knee or hip replacement surgery
Rivaflo is also used to associated treatment for these conditions: Cardiovascular Mortality, Deep Vein Thrombosis, Deep vein thrombosis recurrent, Myocardial Infarction, Pulmonary Embolism, Recurrent pulmonary embolism, Stroke, Systemic Embolism
How Rivaflo works
Rivaflo 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 1000 molecules of thrombin, selective inhibitors of factor Xa are profoundly useful in terminating the amplification of thrombin generation. The action of rivaroxaban is irreversible.
Dosage
Rivaflo dosage
Rivaflo 2.5 mg:
The recommended dose is 2.5 mg twice daily. Patients should also take a daily dose of 75-100 mg Aspirin or a daily dose of 75-100 mg Aspirin in addition to either a daily dose of 75 mg clopidogrel or a standard daily dose of ticlopidine.
Rivaflo 10-20 mg:
Nonvalvular Atrial Fibrillation: For patients with Creatinin Clearance >50 mL/min: 20 mg orally, once daily with the evening meal. For patients with Creatinin Clearance 15-50 ml/min: 15 mg orally, once daily with the evening meal
Treatment of DVT & PE: 15 mg orally twice daily with food for the first 21 days for the initial treatment of acute DVT or PE. After the initial treatment period, 20 mg orally once daily with food for the remaining treatment
Prevention in the risk of recurrence of DVT and of PE: 20 mg once daily with food
Prophylaxis of DVT following Hip replacement surgery: 10 mg once daily for 35 days
Prophylaxis of DVT following knee replacement surgery: 10 mg once daily for 12 days
Side Effects
The most common adverse reaction is bleeding. Increased risk of stroke after discontinuation in nonvalvular atrial fibrillation.
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).
Precaution
Rivaflo can cause bleeding. Promptly evaluate signs and symptoms of blood loss. Rivaflo use not recommended in case of Prosthetic heart valves.
Interaction
CYP3A4, P-GP inhibitors and NSAIDs.
Food Interaction
- Avoid herbs and supplements with anticoagulant/antiplatelet activity. Examples include garlic, ginger, bilberry, danshen, piracetam, and ginkgo biloba.
- Avoid St. John's Wort. Co-administration will decrease levels of this medication.
- Take with food. Rivaflo 15-20mg dose should be taken with food as food significantly impacts the bioavailability at that dose.
- Take with or without food. Rivaflo 10mg dose can be taken with or without food as it does not significantly impact the bioavailability at that dose.

Rivaflo Disease Interaction

Volume of Distribution
The steady state Vd is 50 L
Elimination Route
Following oral administration, rivaroxaban is rapidly absorbed and reaches peak plasma concentration in 2-4 hours. Bioavailability of the 10 mg dose is >80%. However, the 15-20 mg dose have a lower bioavailability if taken in the fasted state and consequently should be taken with food.
Half Life
The terminal half life is 5-9 hours in adults and 11-13 hours in the elderly.
Clearance
Systemic clearance is approximately 10 L/h, so rivaroxaban is considered a drug with low clearance. Renal clearance is ~3-4 L/h.
Elimination Route
Approximately two-thirds of rivaroxaban is excreted into urine (via active tubular secretion in which approximately 36% as unchanged drug and 30% as inactive metabolism). The remaining third of the administered dose is excreted via feces in which 7% is in the form of unchanged drug and 21% as inactive metabolites.
