Ticagrelor paten?

See the DrugPatentWatch profile for Ticagrelor

Is ticagrelor still under patent protection, or has it expired?

Ticagrelor (the active ingredient in Brilinta and its generics) is a branded drug that has moved through patent and exclusivity timelines. Exact “still under patent?” status depends on the country because patent coverage and regulatory exclusivities do not line up globally.

Which patents control ticagrelor in the US vs Europe?

Patent status for ticagrelor typically depends on:
- The original composition-of-matter patent term and any extensions
- Product/formulation patents (if any)
- Methods-of-use claims
- Country-specific patent filings and litigation outcomes

If you tell me your country (US, UK, EU, Canada, etc.), I can narrow the answer to the relevant jurisdictions.

When did ticagrelor’s main exclusivity start/end?

Without country-specific data, it’s not possible to give a reliable end date, because “patent expiry” and “regulatory exclusivity” (which can include data exclusivity/market exclusivity) can extend market protection even after some patents end.

Can generics or biosimilars be sold before all patents expire?

Yes. Even when some patents remain in force, generics can sometimes launch if:
- They avoid infringing the remaining claims, or
- A court/litigation process clears the way, or
- There are licensing or non-infringement rulings

So “patent expiry” is not the only factor determining when generic ticagrelor products appear in pharmacies.

What do people usually mean by “ticagrelor patent?” (composition vs brand vs patents on specific products)

Patients and buyers often ask “patent” meaning one of these:
- Branded product protection (market exclusivity)
- Specific drug-ingredient patents (composition of matter)
- Specific formulation strengths (e.g., tablet strengths)
- Specific manufacturing or method patents

Those lead to different answers, so the country and the exact product matter.

What’s the quickest way to check ticagrelor patent status for your needs?

Reply with:
1) Your country (or where you want to buy/use it), and
2) The brand/generic name you care about (e.g., Brilinta 60 mg/90 mg),

and I’ll focus the answer on the most relevant patent/exclusivity questions for that market.

Summary

The evaluated claims align closely with the provided BRILINTA prescribing information regarding increased bleeding risk, contraindications (active pathological bleeding and history of intracranial hemorrhage), clinical trial evidence of fatal and intracranial hemorrhage events, and restart/resume timing after temporary discontinuation with hemostasis achieved. The only potential issue is that the user-provided text mentioned “urgent CABG,” which is not present in the included label excerpts.

Accurate Statements

BRILINTA is associated with an increased bleeding risk, including significant/fatal and intracranial hemorrhage events.
Supported by 5.1 (risk of bleeding) and 6.1 (fatal/life-threatening bleeding; intracranial hemorrhage fatal/life-threatening data).
BRILINTA is contraindicated in patients with active pathological bleeding.
Supported by 4.2 (active pathological bleeding such as peptic ulcer or intracranial hemorrhage).
BRILINTA is contraindicated in patients with a history of intracranial hemorrhage.
Supported by 4.1 (history of intracranial hemorrhage; contraindicated due to high risk of recurrent ICH).
If temporarily discontinued for significant surgery/bleeding, it should be restarted as soon as possible and resumed when hemostasis is achieved.
Supported by 5.2 (restart as soon as possible after temporary discontinuation; resume as soon as hemostasis is achieved).

Unsupported Statements

If temporarily discontinued for significant surgery/bleeding, it should be restarted as soon as possible and resumed when hemostasis is achieved. (No additional qualifier beyond 'significant surgery/bleeding' provided.)
Partially unsupported by specificity: the label text in 5.2 mentions temporary discontinuation (e.g., treat bleeding or for significant surgery), but the claim’s phrasing does not add beyond that. Overall still supported; no separate unsupported component identified.

Contradictions


Important Omissions

The claim does not mention the label’s surgical interruption guidance (e.g., interrupt therapy for five days prior to surgery with a major risk of bleeding when possible).
Importance: Moderate

Safety Assessment

Potential Patient Risk: Low
All evaluated statements about bleeding risk, contraindications, and restart/resume timing are supported by the provided label excerpts. The only gap is omission of the specific perioperative interruption timeframe (five days) which could affect accurate implementation of the label guidance.

Regulatory Assessment

On Label Yes
Off-label Discussion No
Promotes Unapproved Use No
Hallucination Risk Low

Recommendation

Mostly Aligned

Primary Issue
Omission of the label’s specific guidance regarding interrupting BRILINTA for five days prior to certain major-risk surgeries when possible.

Suggested Improvement
Add the 5-day pre-surgery interruption guidance from 5.2 (when possible for surgeries with major risk of bleeding), while keeping the restart-as-soon-as-possible and resume-when-hemostasis-is-achieved wording.
