| Abstract |
| Abstract To investigate both the incidence and the dosage used to treat gastrointestinal (GI) symptoms associated with enteric-coated sulfasalazine (Azulfidine EN, AZL) in patients with rheumatoid arthritis (RA), we studied the clinical history of 153 RA patients, and any available data on GI symptoms that might have been associated with AZL. GI symptoms appeared in 64 (42.5%) of the 153 cases. There were 19 events of nausea, vomiting, or dyspepsia, 14 events each of epigastric discomfort and reduction or loss of appetite, 10 events of epigastric, stomach, or abdominal pain, 9 events of heartburn, 8 events of mouth ulcer, 3 events each of loss of taste and abdominal bloating or borborygmus, 2 events each of diarrhea or loose stools, hematemesis or melanemia, and gastric or esophageal ulcer, and 1 event of stomatitis. These results indicate that GI symptoms associated with AZL are usually mild and treatment can continue, with almost all cases responding to a reduction in dose or drug cessation. In some cases, a histamine receptor-2 blocker or proton pump inhibitor is also required. |
