Evaluation of the safety of inpatient empagliflozin in a real-world setting

Abstract

Background

Empagliflozin is a sodium glucose co-transporter 2 (SGLT2) inhibitor recommended by the American Diabetes Association for outpatient use. Support for its inpatient role is not well established due to possible safety concerns.

Methods

This was a retrospective study at an academic medical center between January 1, 2021, and December 31, 2021, evaluating the safety and efficacy of empagliflozin compared to other oral antihyperglycemic agents. Patients with established heart failure with or without diabetes were included if they received at least one dose of oral antihyperglycemic agent with 48 hours of fingerstick blood glucose checks during the hospitalization. A total of 227 patients were included. The primary endpoint was a composite of adverse events including urinary tract infection, acute kidney injury, diabetic ketoacidosis, renal replacement therapy, and necrotizing fasciitis. Additional endpoints included daily insulin requirements, hypoglycemia, and hypotension.

Results

Rates of composite adverse events were similar between the empagliflozin group and other oral antihyperglycemic agents (19.3% vs. 12.6% respectively, P = 0.17). There were no instances of renal replacement therapy, diabetic ketoacidosis, or necrotizing fasciitis. The secondary endpoint of basal insulin requirements showed no differences between the two groups. In the empagliflozin cohort, more patients experienced hypotension (23.4% vs. 7.8%; P < 0.01).

Conclusion

This real-world study of empagliflozin use in the inpatient setting found no significant differences in safety endpoints between empagliflozin and other oral antihyperglycemic agents. Larger-scale studies need to be performed before the use of empagliflozin can be routinely recommended in the inpatient setting.
