Background Liraglutide is a human glucagon-like peptide-1 analogue (GLP-1) indicated in the treatment of adults with type-2 diabetes mellitus to achieve glycaemic control, combined with oral antidiabetic agents, increases insulin secretion and decreases glucagon secretion, in a glucose-dependent manner.

Purpose To analyse the adequacy and effectiveness of liraglutide in patients with type-2 diabetes mellitus.

Material and methods Retrospective 2 year observational study (September 2014 to September 2016) of all patients with type-2 diabetes mellitus treated with liraglutide for at least 6 months. Data were obtained from the application of laboratory tests, electronic medical records (DIRAYA) and the application of endorsements. The variables collected were: sex, age, time of initiation of treatment with liraglutide and value of glycosylated haemoglobin (HbA1c) before and after 6 months of treatment. Adequate use of liraglutide was considered when baseline HbA1c was greater than or equal to 7.5% and treatment was effective if reduction of HbA1c at 6 months was greater than or equal to 1%.

Results The total number of patients with type-2 diabetes mellitus treated with liraglutide during the study period was 32. Six patients were excluded due to lack of data. Of the remaining 26 patients, 14 (54%) were females with a median age at the start of treatment of 51 years (37–68). According to the HbA1c values, 73% of the patients met the criteria of adequacy of liraglutide use. Median HbA1c at baseline: 8.6% (5.4–13.6) and median HbA1c at 6 months of treatment: 7.4% (5.2–10.6). For 11 patients (42%), treatment with liraglutide was considered effective. In all but two, there was a decrease in HbA1c. The mean decrease in Hb1Ac in successful patients was 1.03%.

Conclusion Several studies have shown that the addition of liraglutide to oral antidiabetic drugs is associated with better glycaemic control in patients with type-2 diabetes mellitus. In our study, despite adequate use in most patients, the decrease in HbA1c was not sufficient to be considered effective in more than half of the patients.
