Abstract

Background: The benefits of optimum blood pressure (BP) control in patients with diabetes exceed the benefits of glycaemic control and extend to the prevention of both macro-vascular and micro-vascular complications in patients suffering from both hypertension and diabetes mellitus. Aims &
Objective: To investigate the utilization patterns of anti-hypertensive drugs and to evaluate blood pressure (BP) control among diabetic-hypertensive patients with and without reduced renal function. Material and Methods: A prospective, observational study carried out at medicine department of SBKS Medical College and Research Centre, Piparia. The pattern of use of antihypertensive drugs in 50 hypertensive-diabetic patients was evaluated in correlation with its renal function and BP control achieved was compared in patients with and without reduced renal function.
Results: Total 63 antihypertensive medication episodes were prescribed for 50 patients. Out of which 76% patients were receiving 1 drug, 22% receiving 2 drugs and 2% receiving 3 drugs of different antihypertensive class. Most patients were receiving Angiotensin-Converting-Enzyme-Inhibitors (ACE-I)/Angiotensin-Receptor-Blockers (ARBs) (60%), followed by CCBs (24%), beta-blockers (20%), and diuretics (16%). Patients on monotherapy were mostly receiving ACE-I/ARB (65.78%). Beta blockers were more commonly prescribed in patients with reduced renal function (p=0.005). BP control was achieved in 63.15% patients in monotherapy and 33.33% in polytherapy group. Control of systolic and diastolic BP was significantly higher in patients without reduced renal function than patients with reduced renal function (p<0.05). Conclusion: There was suboptimum use of combination therapy among diabetic-hypertensive patients in general and specifically in developing countries as reflected by control achieved in systolic and diastolic BP which requires concern of all healthcare professionals.
