Antazoline HCL

Antazoline HCl (CAS 2508-72-7), an antihistamine active ingredient, is manufactured directly by Polpharma to pharmaceutical grade, drawing on the company's long-standing in-house commercial manufacturing of the full antazoline product family with all intermediates produced internally and no nitrosamine-contamination risk, meeting EP standards. The supplier notes that in patent-protected markets such as Poland this product is offered only to support regulatory submissions or R&D rather than for direct sale, and it is distributed across North America, Europe, Australasia, Asia, the Middle East and Africa.
