Condition(s) targeted: Arterial Hypertension; Hypertension, Resistant to Conventional Therapy; Diabetes Mellitus

Intervention: spironolactone (Drug); placebo (Drug)

Phase: Phase 3

Status: Completed

The purpose of this study is to estimate the effect of spironolactone on blood pressure resistant to therapy in type-2 diabetics.

Clinical Details

Official title: South Danish Hypertension and Diabetes Study

Study design: Allocation: Randomized, Endpoint Classification: Safety/Efficacy Study, Intervention Model: Parallel Assignment, Masking: Double Blind (Subject, Caregiver, Investigator, Outcomes Assessor), Primary Purpose: Treatment

Primary outcome:

Change of of Systolic Blood Pressure

Change of Diastolic Blood Pressure

Secondary outcome: Adverse Effects

Detailed description: The primary object of the study is to estimate the effect of addition of low dose spironolactone to antihypertensive treatment with at least three antihypertensive drugs in patients with type-2 diabetes and blood pressure over 130/80 mmHg. Secondary aims are to estimate how many of these patients have their blood pressure controlled by the addition of spironolactone, to investigate whether the addition of spironolactone affects insulin sensitivity and urinary protein secretion and to estimate the incidence of adverse effects of the aldosterone antagonist.
