common medications for type 2 diabetes
Improved HbA1c
All study medications (insulin glargine, liraglutide, sitagliptin, and glimepiride) when added to metformin lowered HbA1c. After 4 years of follow-up, participants taking liraglutide or insulin glargine were most successful in maintaining target blood glucose levels.
Side Effects
On average, participants in all treatment groups lost weight. Over 4 years, participants in the liraglutide and sitagliptin groups lost more weight than those assigned to the glargine and glimepiride groups. Overall, severe hypoglycemia was rare. Participants taking liraglutide reported more frequent gastrointestinal side effects and weight loss compared to the other 3 groups.
Subgroup Differences
No differences were seen in participants reaching the primary outcome of HbA1c level of 7.0% or higher, by sex, age, or race or ethnic group for subgroups prespecifed by the study.
Cardiovascular Benefits
Liraglutide reduced cardiovascular disease, representing the first demonstration of the CVD effectiveness of a GLP-1 receptor agonist RA in a generally low-risk population.

Diabetes-Specific (Mircrovascular) Complications
In the setting of excellent glycemic and other risk-factor management, all four medications were similarly effective in lowering the risk of microvascular disease.
Genetic Factors Influencing Response to Individual Therapies
Specific genetic factors were identified that influence the response to individual medications.
