15 RANEXA CAN BE USED IN PATIENTS WITH CAD AND DIABETES ● Ranexa does not increase the incidence of hypoglycemia compared with placebo ● Ranexa does not increase the incidence of: ─ Weight gain ─ Cardiovascular adverse events ─ Dyslipidemia (LDL, HDL, total cholesterol, and triglycerides) ─ Clinically relevant changes in blood pressure or heart rate Timmis AD, et al. Eur Heart J 2006;27:42-48

16 SUMMARY ● Ranolazine significantly and dose- dependently reduces HbA1c. ● The magnitude of HbA1c lowering by ranolazine is correlated with the levels of HbA1c and FPG at baseline. ● There was no increase in the incidence of hypoglcyemia in ranolazine-treated patients
