title: Effects of Terazosin on Glycemic Control, Cholesterol, and Microalbuminuria in Patients with Non--Insulin-Dependent Diabetes Mellitus and Hypertension.
abstract: The use of antihypertensive agents that have positive or neutral effects on blood sugar, lipid profiles, and microalbuminuria can be important clinical treatment for patients with diabetes. We evaluated the effects of both terazosin, a selective alpha-one-adrenergic blocker, and hydrochlorothiazide (HCTZ), a standard mild antihypertensive agent, on glycemic control, urinary albumin excretion rate overnight total cholesterol, and other parameters in non--insulin-dependent diabetes mellitus (NIDDM) patients. A randomized, placebo-controlled, cross-over design was implemented in 25 patients. Over an 8-week treatment period fasting plasma glucose (FPG) and glycosylated hemoglobin (GHgb) improved in the terazosin group. Post-treatment FPG was 200 plus minus 85 and 187 plus minus 71 for patients who received HCTZ and terazosin, respectively. Although the GHgb improved significantly for terazosin patients (12.2 plus minus 5.8 for HCTZ versus 10.7 plus minus 4.6 for terazosin, p = 0.03), microalbuminuria did not improve in terazosin patients in this pilot study. A larger randomized study with tighter blood pressure end points are needed to assess fully the impact of terazosin on micoroalbuminuria and overall glycemic control in the NIDDM patient.
