A new study from the University of Illinois Springfield suggests that a common diabetes medication may do more than control blood sugar. Researchers found that the drug, sitagliptin, may help protect blood vessels and support overall heart health.

Sitagliptin is currently prescribed after a Type 2 diabetes diagnosis to help manage blood sugar levels. The UIS study highlights that its effects on blood vessels could one day lead to new strategies to prevent or reduce complications from heart disease.

The study was co-authored by Natalya Zinkevich, assistant professor of biology; Franki Miller, a 2024 UIS biology graduate and current Master of Public Health student; and Abisola “Mercy” Olowofeso, a second-year Master of Public Health student. Their research was published in the journal Cardiovascular Science.
