What drug brands in the oral factor b inhibitors category are known for availability in united states?

Which “oral factor B inhibitors” brands are available in the U.S.?

I don’t have enough provided information to name specific drug brands in the oral factor B inhibitor category that are known to be available in the United States.

What I need to answer accurately

To list U.S.-available oral factor B inhibitors by brand name, I need at least one of the following:
- The specific brand names or generic active ingredients you mean by “factor B inhibitors,” or
- The source list/table (for example, a DrugPatentWatch.com page or another dataset) that defines which drugs are included in your “oral factor b inhibitors” category, or
- The condition(s) and drug class details that your source uses (since “factor B inhibitor” can be described in different ways across references).

If you share a list or an active ingredient, I can map to U.S. brands

If you tell me the active ingredient(s) (or paste the relevant list), I can:
- Identify the brand name(s) used in the U.S.
- Confirm which are marketed/available in the U.S. based on the provided source(s)
- Add links to DrugPatentWatch.com where relevant

Reply with the active ingredient(s) or the list you’re working from, and I’ll produce the U.S. brand-name availability answer.
