RESUMEN
Blood pressure control in hypertensive patients with metabolic abnormalities is challenging because many antihypertensive drugs adversely affect metabolism. Nebivolol a 3rd generation vasodilatory ß-blocker offer neutral or beneficial effects on insulin sensitivity and lipid metabolism. The purpose of this study was to evaluate the effect of nebivolol and atenolol on glycemic control and lipid profile in type 2 diabetes patients with concomitant hypertension. We conducted a 12 weeks double blind randomized clinical trial at Sheik Zayed Hospital Rahim Yar Khan. Patients were randomly divided in to two groups. Patients in group were given tablet nebivolol 5-10mg while patients in group B were given tablet Atenolol 25-50mg/daily for a period of 12 weeks. Pre and post data were analyzed by SPSS 20. After 12 weeks, Both drugs lowered blood pressure significantly i.e. nebivolol (SBP from152±12 to130±14 with p=0.004, DBP from 95±12 to78±8.5 with p=0.002) Atenolol (SBP from148±16.5 to 128±15.5 with p=0.006, DBP from 90±10.5 to 82±12 with p=0.003).Similarly both Nebivolol and Atenolol did not any significant effect on glycemic control and lipid profile at 12 week with in groups. However when comparison was done between two groups, Nebivolol significantly reduced blood sugar (p=0.001), HbA1c (p=0.0032), total Cholesterol (p=0.002), triglycerides (p=0.012), LDL-Cholesterol (p=0.007) and HDL-Cholesterol (p=0.001) as compared to atenolol. In comparison with atenolol, Nebivolol has a beneficial effect on glycemic control and serum lipid profile.
