A. Anti-inflammatory drugs A. Anti-inflammatory drugs Anti-inflammatory drugs are often the first Anti-inflammatory drugs are often the first step in the treatment of IBD. They include:step in the treatment of IBD. They include:
- - SulfasalazineSulfasalazine It is a sulfa drug, in the gut is converted to It is a sulfa drug, in the gut is converted to
sulfapyridine and 5-ASA ( 5-amino sulfapyridine and 5-ASA ( 5-amino salicylates )salicylates )
Sulfapyridine has no antiinlammatory Sulfapyridine has no antiinlammatory effect, absorbed to systemic circulation and effect, absorbed to systemic circulation and responsible for most of the side effects to responsible for most of the side effects to sulfasalazine including allergysulfasalazine including allergy
5-ASA remains in the colon and has good 5-ASA remains in the colon and has good antiinflammatory effectantiinflammatory effect
