Successful Resolution of Glucose Toxicity With the Use of Fixed-Ratio Combination Injection of Basal Insulin and Short-Acting Glucagon-Like Peptide 1 (GLP-1) Receptor Agonist

Abstract

Chronic hyperglycemia leads to a decrease in glucose-stimulated insulin secretion and an increase in insulin resistance. Resolving these glucose toxicities is pivotal in type 2 diabetes therapy because the decline in insulin secretion and insulin sensitivity causes further hyperglycemia. Conventionally, multiple daily insulin injection therapy was applied in such a situation. However, it could not be easily introduced, especially in outpatients. We present a case involving the successful resolution of glucose toxicity easily, immediately, and safely by using a fixed-ratio combination (FRC) injection of basal insulin and short-acting glucagon-like peptide 1 (GLP-1) receptor agonists (GLP-1 RA). Additionally, we discuss the advantages of this new injection therapy.
