OBJECTIVE

2

To excavate the risk signals of adverse events （AE） related to dipeptidyl peptidase-4 （DPP-4） inhibitors， and to provide reference for clinical safe use of these drugs.

METHODS

2

AE reports of five DPP-4 inhibitors （sitagliptin， saxagliptin， linagliptin， vildagliptin， anagliptin） reported in FAERS database from October 17th， 2006 to December 31st， 2021 were collected. The reporting odds ratio （ROR） method was used for data mining， and the systematic organ classification （SOC） and preferred terms （PT） in the drug ADR terminology set of the

Medical Dictionary for Regulatory Activitios

（24.0 edition） were used for classification statistics.

RESULTS

2

A total of 120 510 AE reports related to DPP-4 inhibitors were retrieved， with 1 707 risk signals， including sitagliptin （80 570 reports， 717 signals）， saxagliptin （10 009 reports， 173 signals）， linagliptin （18 214 reports， 317 signals）， vildagliptin （7 893 reports，375 signals） and anagliptin （3 824 reports，125 signals）. In these reports， women （47.27%） were more than men （44.61%）； the age of the patients mainly ranged from 61 to 75 years old （28.37%）. The United States had the largest number （56.17%）； there were 65 458 serious AE reports （54.32%）， mainly hospitalization or prolonged hospitalization time （36.28%）. Sitagliptin， saxagliptin and anagliptin mainly induced gastrointestinal diseases； sitagliptin mainly caused endocrine system diseases， kidney and urinary system diseases， various examinations； vildagliptin mainly resulted in endocrine system diseases， systemic diseases and various reactions at the administration site， nervous system diseases， etc. Among them， risk signals of sitagliptin and liggliptin mainly manifested as the increase of blood glucose， those of saxagliptin as the congestive heart failure and heart failure， and those of vildagliptin and anagliptin as pemphigoid and vomiting respectively. The results of PT analysis of two or more drugs showed that the increase of blood glucose and pancreatitis had the greatest correlation with sitagliptin； the weight loss had the greatest correlation with saxagliptin； renal failure had the greatest correlation with linagliptin； diabetic ketoacidosis had the greatest correlation with anagliptin. Hypoglycemia， acute kidney injury， increased glycated hemoglobin， pemphigoid and lactic acidosis were the most associated with vildagliptin.

CONCLUSIONS

2

When DPP-4 inhibitors were used clinically， the blood glucose level and other blood biochemical indexes of patients should be monitored， and skin condition， the pancreas and kidney function should be paid attention to. If related AE occurred， timely intervention measures should be taken to ensure the medication safety of patients.
