Pharmacological action
Mesalazine – 5-aminosalicylic acid – is the active component of sulfasalazine.
Pentasa ® granules are mesalazine microbeads coated with an ethyl cellulose coating. The therapeutic effect of mesalazine after oral administration is more due to the local effect on the inflamed intestinal tissue than the systemic effect.
The therapeutic effect of mesalazine is manifested by local contact with the affected intestinal mucosa.
Mesalazine inhibits leukocyte chemotaxis, reduces the production of cytokines and leukotriene, and also reduces the formation of free radicals in inflamed intestinal tissue. But the exact mechanism of action of mesalazine is not fully understood.
