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 has no approved brand name. It only has orphan drug status, a narrower label that helps a drug get developed for a specific rare use, without being full approval.
