Nesina is a dipeptidyl peptidase 4-inhibitor approved in 2013 for treating type 2 diabetes. It works by increasing incretin hormone levels to reduce fasting and postprandial glucose levels. Common side effects include hypoglycemia and nasopharyngitis. It is metabolized in the liver with a half-life of 21 hours and is excreted primarily in urine. Patients should be monitored for signs of pancreatitis and caution is needed with renal impairment or abnormal liver function tests.
4. Mechanism of action:-
It increases the activation of incretin hormones, thereby

postprandial glucose concentrations .
