The medications most frequently linked to gastrointestinal ulcers include nonsteroidal anti-inflammatory drugs, anticoagulants, antiplatelet agents, and immunosuppressants. In the multifactorial logistic regression analysis, Sevelamer and acetylsalicylic acid emerged as the two medications most strongly associated with the highest incidence of gastrointestinal ulcer cases.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>Nonsteroidal anti-inflammatory drugs, Sevelamer, immunosuppressants, and other medications have shown a significant positive association with gastrointestinal ulcers.
