Beneficial effects of sitagliptin and metformin in non-diabetic hypertensive and dyslipidemic patients.

Obesity, dyslipidemia and hypertension are major risk factors for cardiovascular disease and its associated complications. To evaluate the beneficial effects of sitagliptin and metformin in non-diabetic dyslipidemic and hypertensive patients. A prospective randomized clinical trial was conducted on 70 newly diagnosed dyslipidemic patients with BMI > 25 and blood pressure > 130/80 at outpatient clinic of medical unit-1 of Sheikh Medical College/Hospital, Rahim Yar Khan. They were divided in to three groups each containing 35 patients; First group served as a healthy control while second and third study groups were given tablet sitagliptin 50mg and tab metformin 850mg respectively twice a day for twelve weeks. After three months treatment with sitagliptin and metformin there was significant reduction in body weight (Sitagliptin 6.5% vs Metformin 7.65%) and BMI (Sitagliptin 2.2% vs Metformin 2.8%) with p <0.05. Metformin caused a significant reduction in blood pressure with p < 0.05 (i.e. SBP 9.9% & DBP 6.4%) while sitagliptin caused a highly significant p <0.01 reduction in blood pressure (i.e. SBP 15.8% & DBP 12.2%). There was significant improvement in lipid profile with sitagliptin p<0.05. The percent reduction in value of TC, TG and LDL-C was 20.2%, 13.8% and 23.7% while HDL-C value was increased 11.2% respectively. There was highly significant improvement in lipid profile with metformin p<0.01. The percent reduction in value of TC, TG and LDL-C was 27.8%, 28.2% and 40.4% while HDL-C value was increased 16.8% respectively. Both drugs improve cardiometabolic risk factors independently in non-diabetic patients.
