Is thymosin alpha 1 the same as Zadaxin?

Yes, Zadaxin is the brand name under which thymosin alpha 1 is approved and sold in more than 30 countries, mainly for hepatitis. In the US it does not carry that or any other approved brand name; it holds orphan drug designation only, a narrower status that supports development for a specific rare use without amounting to full approval.
