Find answers to common questions about Mesalamine and Mesalazine products and services
Mesalamine and Mesalazine are different names for the same active pharmaceutical ingredient — 5-Aminosalicylic acid (5-ASA), CAS 89-57-6. Mesalamine is the INN (International Nonproprietary Name) used in the United States (USP monograph). Mesalazine is the INN used in Europe (EP/BP), Japan, India, and most other global markets. DK Pharmachem supplies this API under both names and to both USP and EP/BP/IP pharmacopoeial specifications.
DK Pharmachem supplies Mesalamine / Mesalazine API conforming to BP (British Pharmacopoeia), USP (United States Pharmacopeia), EP (European Pharmacopoeia), and IP (Indian Pharmacopoeia) standards at ≥99% purity. This multi-pharmacopoeia compliance enables a single DK Pharmachem qualification to support regulatory filings across the US, EU, UK, and Indian markets.
