IntroductionAcute pancreatitis (AP) is an inflammatory disease with multiple etiologies, and the emergence of complications. Between 0.1-5% of cases are attributed to drugs. The absence of specific characteristics complicates the diagnosis and treatment of drug-induced AP. Reviewing patients admitted with the diagnosis of drug-induced AP can provide information and improve its management.Patients And MethodsThis is a descriptive, observational, and retrospective study. All patients admitted to the Hospital Universitari de Bellvitge between June 2007 and March 2023 with suspected drug-induced AP were included. The data were obtained from the hospital pharmacovigilance program database.ResultsThirty-eight patients with suspected drug-induced AP were identified, representing 0.62% of all adverse drug reactions (n=6.085). Of these, 65.8% (n=25) had a single suspected drug. The median latency period for the onset of adverse drug reactions was 160.5 days (IQR: 18-582 days), and the median hospital stay was 5 days (IQR: 3-7 days). Fifty-nine suspected drugs were identified, involving 26 active principles. Azathioprine and atorvastatin were the most frequent, with 9 cases each (15.2%), followed by enalapril with 8 cases (13.6%). Drug etiology was assessed in 23 cases (60.5%), and the suspected drug was discontinued in all cases. There was one fatal case documented (2.63%).ConclusionThis study can contribute to better understanding of drug-induced pancreatitis episodes. We propose a diagnostic algorithm that includes the assessment of the drug as a possible cause.Copyright © 2024 Elsevier España, S.L.U. All rights reserved.
