Objectives of the Study: The aim of the study was to compare the efficacy and tolerability of different classes of antihypertensive drugs in diabetic and nondiabetic patients (NDPs) with essential hypertension. Material and Methods: The study was conducted in Mayo Hospital, Punjab Institute of Cardiology, and National Defence Hospital, Lahore, Pakistan, on 200 hypertensive patients with diabetes and 230 hypertensive patients without (Three hospitals) diabetes. Both male and female patients of age between 30 and 80 years with systolic blood pressure (SBP) above 130 mmHg and diastolic blood pressure (DBP) above 80 mmHg were enrolled in the study. Angiotensin converting enzyme inhibitors (ACEI), beta-blocker (βB), calcium-channel blocker (CCB), diuretics (D), angiotensin receptor blocker (ARB) as well as α-blocker classes of antihypertensive drugs were used. These drugs were used as monotherapy as well as combination therapy. The study was conducted for 4 months (July–October). After 4 months, patients were assessed for efficacy by monitoring blood pressure (BP) and tolerability by assessing safety profile on renal function, liver function as well as lipid profile. Results: Significant control in mean BP by all drug groups was observed in "both groups that is patients with diabetes and without diabetes." The efficacy and tolerability data revealed that in diabetic patients with hypertension, the highest decrease in SBP and DBP was observed using monotherapy with ACEI, two-drug combination therapy with ACEI plus diuretic, ARBs plus diuretic, ACEI plus CCBs, three-drug combination therapy with ACEI plus CCBs plus diuretic, and four drug combination therapy with ACEI plus CCBs plus diuretic plus βBs, ARB's plus CCBs plus diuretic plus βBs while in NDPs, monotherapy with diuretic, two-drug combination therapy with ACEI plus CCBs, ACEI plus βBs, three-drug combination therapy with βBs plus ACEI plus D was found more effective in controlling SBP as well as DBP. Adverse effects observed were dry cough, pedal edema, dizziness, muscular cramps, constipation, palpitations, sweating, vertigo, tinnitus, paresthesia, and sexual dysfunction. Conclusion: All classes of antihypertensives were found to control blood pressure significantly in both groups of patients that is diabetic patients with hypertesion and non-diabetic patients with hypertension.
