Patient summary
Mesalazine as a 400mg prolonged-release tablet, used in the management of ulcerative colitis and Crohn's disease. The release is spread along the gut.
Mechanism of action
Mesalamine is an aminosalicylate that acts locally in the gastrointestinal tract, inhibiting the production of prostaglandins and leukotrienes, which reduces mucosal inflammation in conditions like ulcerative colitis.
Pentasa contains mesalazine, an active ingredient used to manage conditions such as ulcerative colitis and Crohn’s disease. The same medication is also sold under the brand name Salofalk, which is supplied as a 400mg tablet. This treatment is designed to assist with the management of chronic inflammation in the digestive tract.
Buying Pentasa online
For expats or residents living far from established supply chains, ordering this medication online is a reliable way to maintain consistent therapy across the region. Generic mesalazine often serves as a more affordable alternative to the original branded product for those managing long-term gut health.
Is the Pentasa on SGMeds a generic?
Yes. SGMeds ships a generic with the same active ingredient (mesalazine) at the same strength, not the original Pentasa made by Ferring Pharmaceuticals. We use the brand name so you can find the medicine, and the generic's manufacturer varies with stock.
