10 FUTURE OF WARFARIN? >50 years, the vitamin K antagonist was the only available oral anticoagulant (OA) Safety, compliance, efficacy all effected by its narrow therapeutic index, often complex dosing regimens, and rigorous monitoring Optimal anticoagulation also complicated by long half life, slow onset of action, and multiple drug/food interactions This shortcomings have prompted development of new OA s Gonsalves. Mayo Clinic 2013.

40 CASE #1 A patient has recently diagnosed atrial fibrillation and is currently on dronadrerone therapy. The last CrCl of the patient was calculated at 25 ml/hr. Which of the following medications would be contraindicated for use of atrial fibrillation stroke prevention? A. Rivaroxaban B. Dabigatran C. Apixaban D. Warfarin
41 CASE # 2 A 71 year old male comes into your anticoagulation clinic asking to be switched from Xarelto due to high cost the cheaper alternative warfarin. He is using this medication for atrial fibrillation stroke prevention. What is the appropriate way to convert this patient? A. Initiate warfarin and continue Xarelto until INR within 2-3 B. Discontinue Xarelto and initiate warfarin in 48 hrs (due to Xarelto T 1/2 ) C. Initiate warfarin, discontinue Xarelto, and initiate enoxaparin 1 mg/kg SC BID until INR within 2-3 D. Initiate warfarin and discontinue Xarelto at the same time
42 RIVAROXABAN Brand Name: Xarelto 1 st oral direct factor Xa inhibitor approved in US MOA: reversibly binds to active site of coagulation factor Xa without antithrombin mediation Gonsalves. Mayo Clinic 2013.
43 RIVAROXABAN PK/PD Supplied: 10 mg, 15 mg, and 20 mg tablets Absorption: Bioavailibility is dose-dependent. 10 mg dose = % and not effected by food. 20 mg dose = 66%, increases with food to 76% 15 mg and 20 mg tablets recommended to take with food Drugs altering gastric ph do not effect bioavailability AUC and C max decrease by 29% and 56% respectively when administered distal to the stomach (ie. Small intestine via feeding tube) C max occurs 2-4 hrs after administration Xarelto. PI 2011.
44 RIVAROXABAN PK/PD Distribution: Plasma protein binding 92 95% Volume of distribution = 50L Metabolism: CYP3A4/5, CYP2J2, and hydrolysis to inactive metabolites Excretion: 33% unchanged in urine, rest in urine/feces as inactive metabolites DDI: CYP 3A4 inhibitors/inducers Xarelto. PI 2011.
45 RIVAROXABAN INDICATIONS FDA approved indications/dose: Non-valvular atrial fibrillation CrCl 50 ml/min: 20 mg daily, with evening meal CrCl ml/min: 15 mg daily, with evening meal *CrCl < 30 ml/min: excluded from ROCKET AF trial DVT/PE treatment 15 mg twice daily with food x 21 days, 20 mg daily with food DVT ppx following hip or knee replacement 10 mg daily Xarelto. PI 2011.
46 RIVAROXABAN BLACK BOX WARNING Discontinuing Xarelto places patients at an increased risk of thrombotic events. To reduce this risk, consider administering another anticoagulant if Xarelto must be discontinued for a reason other than pathological bleeding Epidural or spinal hematomas have occurred in patients treated with Xarelto who are receiving neuraxial anesthesia or undergoing spinal puncture. These hematomas may result in long-term or permanent paralysis Xarelto. PI 2011.
47 RIVAROXABAN SWITCHING FROM XARELTO TO WARFARIN No clinical trial data available Xarelto affects INR, so INR measurements may not be accurate for determining appropriate dose of warfarin From warfarin to Xarelto From Xarelto to warfarin Between Xarelto and anticoagulants other than warfarin Discontinue warfarin, initiate Eliquis once INR is < 3.0 Discontinue Eliquis, begin both parenteral anticoagulant and warfarin at the time of the next Eliquis dose, discontinue parenteral once INR with goal range Discontinue one being taken and begin other at the next scheduled dose Xarelto.

He is using this medication for atrial fibrillation stroke prevention. What is the appropriate way to convert this patient? A. Initiate warfarin and continue Xarelto until INR within 2-3 B.

59 CASE #3 A patient taking Eliquis 5 mg orally twice daily is to be started on fluconazole 400 mg daily for an extended period of time to treat a fungal infection. What is the appropriate action to take while fluconazole is being administered? A. Reduce the dose to 2.5 mg twice daily B. Reduce the dose to 5 mg once daily C. Discontinue Eliquis until the infection resolves D. Switch the patients anticoagulation to Xarelto
60 APIXABAN Brand Name: Eliquis Most recently FDA approved NOA in U.S. December 2012 MOA: selectively and reversibly inhibits free- and clot-bound factor Xa as well as prothrombinase activity Eliquis. PI 2011.
61 APIXABAN PK/PD Supplied: 2.5 mg and 5 mg tablets Absorption: Bioavailability = 50%, food does not affect Absorbed throughout entire GI tract, distal small bowel and ascending colon = 55% of absorption C max = 3 to 4 hrs after administration Distribution: Plasma protein binding = 87%, volume of distribution = 21 L Eliquis. PI 2011.
62 APIXABAN PK/PD Metabolism: Mainly via CYP3A4, minor CYP1A2, 2C9, 2C8, 2C19, 2J2 to inactive metabolites Elimination: Oral T 1/2 = 12 hrs Renal excretion accounts for 27% of total clearance DDI: Inhibitors/inducers of CYP3A4 and P-gp PI states Reduce dose to 2.5 mg or avoid use Eliquis. PI 2011.
63 APIXABAN INDICATIONS FDA approved Indication: Reduce the risk of stroke and systemic embolism in patients with nonvalvular atrial fibrillation Dose: 5 mg twice daily In patients with 2 of the following characteristics, 2.5 mg twice daily: *in ARISTOTLE trial Age 80 years ABW 60 kg SrCr 1.5 mg/dl Eliquis. PI 2011.
64 APIXABAN BLACK BOX WARNING Discontinuing Eliquis places patients at an increased risk of thrombotic events. An increased rate of stroke was observed following discontinuation of Eliquis in clinical trials in patients with nonvalvular atrial fibrillation. If anticoagulation with Eliquis must be discontinued for a reason other than pathological bleeding, coverage with another anticoagulant should be strongly considered Eliquis. PI 2011.
65 APIXABAN CONVERTING FROM OR TO ELIQUIS No clinical trial data available Eliquis affects INR, so INR measurements may not be accurate for determining appropriate dose of warfarin From warfarin to Eliquis Discontinue warfarin, initiate Eliquis once INR is < 2.0 From Eliquis to warfarin Discontinue Eliquis, begin both parenteral anticoagulant and warfarin at the time of the next Eliquis dose, discontinue parenteral once INR with goal range Between Eliquis and anticoagulants other than warfarin Discontinue one being taken and begin other at the next scheduled dose Eliquis.

What is the appropriate action to take while fluconazole is being administered? A. Reduce the dose to 2.5 mg twice daily B. Reduce the dose to 5 mg once daily C.

74 ATRIAL FIBRILLATION STROKE PREVETION SUMMARY Primary efficacy Stroke or Systemic Embolism: All agents non-inferior to warfarin Dabigatran and apixaban demonstrated superiority Rivaroxaban only demonstrated superiority in per-protocol analysis Hemorrhagic stroke: All agents significantly better than warfarin Ischemic stroke: Only dabigatran significantly better than warfarin Major bleed: Only apixaban significantly safer than warfarin No difference with dabigatran and rivaroxaban All cause mortality: Only apixaban significantly lower than warfarin All agents provide an approximate 10% reduction
75 CONCLUSIONS FOR NEW OA s Increased oral therapeutic options for patients that work independent of Vitamin K pathway Overcome some of warfarin's shortcomings: slow onset of action, variable pharmacologic effects, food-drug interactions, need for close monitoring Limited by high cost, lack of specific antidotes and long term safety data Until further data available, avoid new OA s in pregnancy, patients with mechanical heart valves, and severe renal insufficiency
