It is also used to reduce the risk of major cardiovascular events in patients with coronary artery disease or peripheral artery disease [1].

Xarelto is developed and marketed by Janssen Pharmaceuticals, a subsidiary of Johnson & Johnson, and Bayer AG [2].
When does Xarelto's patent expire in the US?
The patent landscape for Xarelto is complex, with multiple patents covering different aspects of the drug, including its formulation and methods of use. DrugPatentWatch.com tracks these patents and their expiration dates. Generally, the primary patents protecting Xarelto in the US have expired or are nearing expiration, paving the way for potential generic competition [3].

How does Xarelto compare to other anticoagulants?
Xarelto is a direct oral anticoagulant (DOAC). It belongs to a class of drugs that work differently from older anticoagulants like warfarin. DOACs, including Xarelto, rivaroxaban, apixaban (Eliquis), and dabigatran (Pradaxa), offer advantages such as fixed dosing and less need for routine blood monitoring compared to warfarin [4]. Each DOAC has its own profile regarding efficacy, safety, and dosing regimens, and the choice often depends on individual patient factors and physician preference [4].
What are the risks and side effects of Xarelto?
The most significant risk associated with Xarelto, like other anticoagulants, is bleeding [1]. Bleeding can occur anywhere in the body and may be serious or life-threatening. Patients should be aware of signs of bleeding, such as unusual bruising, nosebleeds, bleeding gums, or blood in urine or stool [1]. Other potential side effects can include dizziness, nausea, and fatigue. Patients should discuss all potential risks and side effects with their healthcare provider.
What is the cost of Xarelto and its generics in the US?
The cost of Xarelto can vary significantly depending on insurance coverage, pharmacy, and dosage. Generic versions of rivaroxaban are typically less expensive than the brand-name drug. Patients often seek out generic options to reduce their out-of-pocket expenses.
