Generic version of opsumit?

Opsumit is the brand name for macitentan, an endothelin receptor antagonist used to treat pulmonary arterial hypertension (PAH).

Generic version:
- In the United States, there is no FDA-approved generic macitentan (as of my latest update). Opsumit remains the branded product.
- Availability of a generic macitentan can vary by country and depends on patent/exclusivity status in that market. Some other countries may have generic versions if patents have expired or license arrangements exist.

What to do next:
- If you’re in the U.S. and asking about cost or availability, check the FDA’s Orange Book or ask a pharmacist for the latest status.
- If you’re in another country, your pharmacist or local health regulator can tell you whether a generic macitentan is available.
- If cost or access is a concern, talk to your prescriber or a patient assistance program about options. There may be alternatives in the same class (e.g., bosentan, ambrisentan) if appropriate for your condition.

Would you like me to look up the current generic status for a specific country? If so, which country?
