FDA Approves Merck's Januvia

A new oral medication called Januvia (sitagliptin phosphate) has been approved by the U.S. Food and Drug Administration for management of Type 2 diabetes. It's the first in a new class of drugs called DPP-4 inhibitors. Januvia lowers blood sugar levels by blocking an enzyme known as dipeptidyl peptidase IV or DPP-4.
