Identification of Drugs Associated With Oral Ulcers Based on Pharmacovigilance

This study systematically identified approximately 289 drugs significantly associated with oral ulcer risk, including immunosuppressants, cardiovascular drugs and bronchodilators. Based on pharmacovigilance signal detection and regression analysis, patients on long-term treatment with these drugs should receive enhanced oral monitoring. As this is an observational study, further prospective and experimental research is needed to confirm causality.
