<div>Background: Ischemia-reperfusion (I/R) injury is a pathological process mediated by oxidative stress and inflammation that begins with oxygen deprivation. This study, it was aimed to investigate the protective effect of desloratadine on gastric I/R damage in rats.&nbsp; 
 
Methods: Eighteen rats were randomly divided into 3 groups gastric I/R (GIR), gastric I/R + 5 mg/kg oral desloratadine (GIRD) and gastric sham operation (GSG).&nbsp; One hour later desloratadine administration, clips were placed in the celiac arteries of the rats in the GIRD and GIR groups. Ischemia was created by keeping the clips closed for one hour. Afterward, the clips were removed and reperfusion was achieved for three hours. The sham operation was performed on the GSG group. Then, all animals were euthanized with 120 mg/kg ketamine. Malondialdehyde (MDA), total glutathione (tGSH), superoxide dismutase (SOD) catalase (CAT) and interleukin-6 (IL-6) levels were determined in the excised gastric tissues. All tissues were also analyzed histopathologically.&nbsp; 
 
Result: When the GIR group was compared with the GSG, an increase in MDA and IL-6 levels and a decrease in tGSH, SOD and CAT levels were observed (p&lt;0.001). In addition, severe mucosal degeneration, congestion, polymorphonuclear leukocyte infiltration and mucosal edema were detected in the GIR group. Desloratine significantly inhibited both biochemical and histopathological changes (p&lt;0.05).&nbsp;</div>
