First-line high-dose thiazides and first-line beta-blockers are inferior to first-line low-dose thiazides
BACKGROUND Sustained elevated blood pressure , unresponsive to lifestyle measures , leads to a critically important clinical question : What class of drug to use first-line ?
This review answers that question .

The effect of irbesartan on the development of diabetic nephropathy in patients with type 2 diabetes.
BACKGROUND Microalbuminuria and hypertension are risk factors for diabetic nephropathy . Blockade of the renin-angiotensin system slows the progression to diabetic nephropathy in patients with type 1 diabetes , but similar data are lacking for hypertensive patients with type 2 diabetes . We evaluated the renoprotective effect of the angiotensin-II-receptor antagonist irbesartan in hypertensive patients with type 2 diabetes and microalbuminuria . METHODS A total of 590 hypertensive patients with type 2 diabetes and microalbuminuria were enrolled in this multinational , r and omized , double-blind , placebo-controlled study of irbesartan , at a dose of either 150 mg daily or 300 mg daily , and were followed for two years . The primary outcome was the time to the onset of diabetic nephropathy , defined by persistent albuminuria in overnight specimens , with a urinary albumin excretion rate that was greater than 200 microg per minute and at least 30 percent higher than the base-line level . RESULTS The base-line characteristics in the three groups were similar . Ten of the 194 patients in the 300-mg group ( 5.2 percent ) and 19 of the 195 patients in the 150-mg group ( 9.7 percent ) reached the primary end point , as compared with 30 of the 201 patients in the placebo group ( 14.9 percent ) ( hazard ratios , 0.30 [ 95 percent confidence interval , 0.14 to 0.61 ; P < 0.001 ] and 0.61 [ 95 percent confidence interval , 0.34 to 1.08 ; P=0.081 for the two irbesartan groups , respectively ) . The average blood pressure during the course of the study was 144/83 mm Hg in the placebo group , 143/83 mm Hg in the 150-mg group , and 141/83 mm Hg in the 300-mg group ( P=0.004 for the comparison of systolic blood pressure between the placebo group and the combined irbesartan groups ) . Serious adverse events were less frequent among the patients treated with irbesartan ( P=0.02 ) . CONCLUSIONS Irbesartan is renoprotective independently of its blood-pressure-lowering effect in patients with type 2 diabetes and microalbuminuria
