Jump to navigation Jump to search

Indications

* safe & effective in the elderly[18]

Contraindications

* questionable

Pregnancy category: C

Dosage

Tabs: 10 mg

Dosage adjustment in renal failure

Pharmacokinetics

Adverse effects

* treatment of major bleeding

Drug interactions

  • inhibitors of CYP3A4 may increase levels of rivaroxaban
  • inducers of CYP3A4 may decrease levels of rivaroxaban
  • rivaroxaban itself neither induces or inhibits CYP3A4

Laboratory

Mechanism of action

Clinical trials

  • ROCKET AF trial
    • point-of-care device used to measure INR after dosing with warfarin in ROCKET AF trial later recalled by FDA because the device was prone to giving falsely low INR readings[8][22]*
    • falsely low INR readings may have prompted higher doses of warfarin resulting in higher risks for bleeding making rivaroxaban seem comparatively safer[22]
    • authors of ROCKET AF trial reanalyzed their data & concluded that use of the device had not significant clinical effect on the primary efficacy or safety outcomes in the trial
    • data not publically available

* Janssen, the pharmaceutical branch of Johnson & Johnson, knew that a point-of-care device used for measuring INR was giving falsely low readings during the ROCKET AF trial[24]

* FDA concludes results of ROCKET AF trial not effected by faulty monitoring device[27]
