Jentadueto is a medication that combines two active ingredients, linagliptin and metformin, to help manage type 2 diabetes in adults. Linagliptin works by increasing the levels of incretin hormones in your body, which helps regulate your blood sugar levels. Metformin works by decreasing glucose production in the liver and improving insulin sensitivity in the muscles. Jentadueto is suitable for adults with type 2 diabetes who need both linagliptin and metformin in a single tablet for better blood sugar control.
