Description
Mesalazine Product Overview
Mesalazine (C7H7NO3), also called mesalamine or 5-aminosalicylic acid, is a white to light tan powder that is slightly soluble in water. It is sensitive to light and air and slowly darkens on exposure.
Pharmaceutical companies use it in medicines for inflammatory bowel disease. Because it should act locally in the gut, formulations are designed to release the API at the right place: pH-dependent coated tablets, prolonged-release granules, suppositories and rectal suspensions. This makes particle size and impurity profile especially important.
Zyntex supplies it from qualified API producers with lot-specific documentation, only to licensed pharmaceutical companies. Related gastroenterology APIs in our range include Ursodeoxycholic Acid and Lactulose.
