2 The problem Every 33 seconds someone dies from CAD ( one woman dies every 62 seconds) 21 million Americans have diabetes 1 in 3 Americans born in 2000 will have diabetes in their lifetime By million people worldwide may have T2DM 18% of people over the age of 65 have diabetes 2

3 Escalating Epidemic of Type 2 Diabetes Overweight rates are fueling the diabetes epidemic 1,2 References: 1. CDC Data and trends; 2. CDC Prevalence data. 3

4 High blood sugar & Obesity Having hyperglycemia produces many symptoms that that mirror the metabolic problems of having too much fat. ENDOTHELIAL DYSFUNTION OXIDATIVE STRESS VASCULAR INFLAMMATION ABNORMAL CLOTTING METABOLIC ABNORMALITIES HYPERTENSION ABNORMAL LIPIDS 4

Is not recommended in pt with symptomatic heart failure, or pt with established Class III or IV heart failure. Pioglitazone- Proactive A1c lower in pioglitazone group (6.9%) 5.3% lowering of LDL, 8.9% higher HDL, 13.2% lower triglycerides 10% lowering of the primary endpoint in the active group, not statistically significant. 16% reduction in secondary endpoints Heart failure and edema were increased 9

15 S e c t i o n 12, 12.2 Mechanism of Action of Sitagliptin Glucose Ingestion of food Release of active incretins GI tract GLP-1 and GIP JANUVIA (DPP-4 inhibitor) Inactive GLP-1 X DPP-4 enzyme Inactive GIP Pancreas Beta cells Alpha cells dependent Insulin (GLP-1and GIP) Glucosedependent Glucagon (GLP-1) Glucose uptake by peripheral tissue Hepatic glucose production Incretin hormones GLP-1 and GIP are released by the intestine throughout the day, and their levels in response to a meal. Blood glucose in fasting and postprandial states Concentrations of the active intact hormones are increased by JANUVIA (sitagliptin phosphate), thereby increasing and prolonging the actions of these hormones.

23 CareLink Download The patient is always the one in control. You may spend about minutes with your patient face to face 4-5 x year Which leaves the patient in control 1435 minutes EVERY DAY! Teamwork is the ability to work together toward a common vision. It is the fuel that allows common people to attain uncommon results 23
