Primary Outcome Measures:
  • Change of of Systolic Blood Pressure [ Time Frame: 4 months ]
    Change of systolic blood pressure from baseline to study end at four months.

  • Change of Diastolic Blood Pressure [ Time Frame: 4 months ]
    Change of diastolic blood pressure from baseline to study end at four months.

Secondary Outcome Measures:
  • Adverse Effects [ Time Frame: 4 months ]

Enrollment: 119
Study Start Date: March 2010
Study Completion Date: May 2012
Primary Completion Date: March 2012 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: addition of spironolactone
spironolactone is added to previous antihypertensive treatment
Drug: spironolactone
25 to 50 mg once daily
Placebo Comparator: Placebo
Addition of placebo
Drug: placebo
addition of placebo 1 to 2 tablets daily

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.
