Background: Prediabetes is defined as a state of glucose metabolism between normal glucose
tolerance and type 2 diabetes. Continuous β-cell failure and death are the reasons for the evolution
from normal glucose tolerance to prediabetes and finally type 2 diabetes.
Introduction: The necessity of new therapeutic approaches in order to prevent or delay the development
of type 2 diabetes is obligatory. Liraglutide, a long-acting GLP-1 receptor agonist, has 97% homology
for native GLP-1. Identification of the trophic and antiapoptotic properties of liraglutide in preclinical
studies, together with evidence of sustained β-cell function longevity during its administration
in type 2 diabetes individuals, indicated its earliest possible administration during this disease, or even
before its development, so as to postpone or delay its onset.
Methods: Pubmed and Google databases have been thoroughly searched and relevant studies were selected.
Results: This paper explores the current evidence of liraglutide administration both in humans and
animal models with prediabetes. Also, it investigates the safety profile of liraglutide treatment and its
future role to postpone or delay the evolution of type 2 diabetes.
Conclusion: Liralgutide remains a valuable tool in our therapeutic armamentarium for individuals who
are overweight or obese and have prediabetes. Future well designed studies will give valuable information
that will help clinicians to stratify individuals who will derive the most benefit from this agent,
achieving targeted therapeutic strategies.
