Drug-drug interactions of empagliflozin and dapagliflozin
Abstract
The sodium glucose co-transporter2-inhibitors dapagliflozin (Dapa) and empagliflozin (Empa), initially developed as antihyperglycemic agents, are increasingly also prescribed for non-diabetic patients with heart failure (HF). Glucuronidation by uridine-diphosphate glucuronosyltransferase (UGT)1A9 is the main mechanism of metabolism of Dapa, whereas Empa is eliminated mainly by excretion. Both Dapa and Empa are substrates of P-glycoprotein. The risk for drug-drug interactions (DDI) of Empa and Dapa is assumed to be low. Aim of this study was to summarize reports of DDI of Empa and Dapa from the literature.
Search-terms in PubMed were "drug-drug interaction" and AND "sodium glucose co-transporter2-inhibitors" OR "SGLT2" OR "dapagliflozin" OR "empagliflozin". The drugs were classified according the Anatomical Therapeutic Chemical (ATC) system. Included were randomized trials, pharmacovigilance studies, case series, case reports, studies in healthy subjects and in vivo data. The funding of the study and the disclosures of the authors were registered.
In 45 reports DDI of Empa and Dapa with 29 drugs were described (Table). According to the ATC system, these were drugs for the alimentary tract and metabolism (n=5), blood and blood forming organs (n=2), cardiovascular system (n=11), genitourinary system and sex hormones (n=2), antiinfectives (n=2), antineoplastic and immunomodulating agents (n=3), musculo-skeletal system (n=2) and nervous system (n=2). The reports comprised studies…
How strong is the evidence?
Evidence Hub reads this as a randomized trial, done in people. Its evidence level is 2 of 5 (High · randomized trial). Randomized trials of a reasonable size are the strongest single-study design. Reported size: 32 participants or records.
