The patent exclusivity for Xarelto (rivaroxaban) 20mg has largely expired in major markets, paving the way for generic versions.
When did Xarelto lose its market exclusivity?
Xarelto's primary U.S. patent expired in July 2023 [1]. This expiration typically marks the end of the innovator drug's market exclusivity, allowing generic manufacturers to enter the market [2].
Can I buy generic Xarelto now?
Following patent expiry, the U.S. Food and Drug Administration (FDA) has approved multiple generic versions of rivaroxaban [3]. These generic options are now available to patients and healthcare providers.
What does this mean for Xarelto pricing?
The introduction of generic competition generally leads to a significant decrease in drug prices [2]. Patients and insurance providers can expect to see lower costs for rivaroxaban compared to the branded Xarelto.
Who makes generic rivaroxaban?
Several pharmaceutical companies have received FDA approval to market generic versions of rivaroxaban. These include manufacturers such as Accord Healthcare, Granules Pharmaceuticals, and Teva Pharmaceuticals, among others [3].

What are the key patents for Xarelto?
The main patent protecting Xarelto in the U.S. was U.S. Patent No. 7,790,740, which expired in July 2023 [1]. Other patents related to formulation, manufacturing, and methods of use may have had different expiration dates, but the core compound patent's expiry was the most significant for generic entry.
How does generic rivaroxaban compare to brand-name Xarelto?
Generic drugs are required to demonstrate bioequivalence to their brand-name counterparts, meaning they contain the same active ingredient and perform in the same way in the body [4]. Generic rivaroxaban 20mg is therapeutically equivalent to Xarelto 20mg and is approved for the same indications.
What are the potential risks with generic drugs?
While generic drugs are rigorously tested, some patients may experience slight differences in inactive ingredients, which could rarely lead to sensitivities [4]. However, the active ingredient, which determines the drug's efficacy and safety, is identical.
How do drug patents work?
Drug patents grant inventors exclusive rights to their inventions for a set period, typically 20 years from the filing date, to allow them to recoup research and development costs [2]. After patent expiry, other companies can seek regulatory approval to produce and sell generic versions of the drug.
