Addition of Spironolactone in Patients With Resistant Arterial Hypertension
The purpose of this study is to evaluate the efficacy of spironolactone on lowering blood pressure when added to therapy in patients with resistant arterial hypertension.
Arterial hypertension resistant to therapy and requiring treatment with more then three antihypertensive drugs is common. At present there are is no standard therapy for resistant hypertension based on randomised clinical trials, neither data to guide addition of further drugs to therapy. Recently some observational and retrospective trials reported good effect of spironolactone in patients with resistant hypertension, but these data were not validated by prospective randomised clinical trials.
This is a multicentric, randomised, double blind clinical trial, which will evaluate the effect of addition of 25 mg spironolactone to current medication compared to placebo. The study will enroll patients with blood pressure over 140/90 mmHg during a clinical examination, which are using at least three antihypertensive drugs, one of them being a diuretic. Average daytime systolic and diastolic blodd pressure will be evaluated by ABPM (ambulatory blood pressure monitoring).

Medical and Biotech [MESH] Definitions
A condition in pregnant women with elevated systolic (>140 mm Hg) and diastolic (>90 mm Hg) blood pressure on at least two occasions 6 h apart. HYPERTENSION complicates 8-10% of all pregnancies, generally after 20 weeks of gestation. Gestational hypertension can be divided into several broad categories according to the complexity and associated symptoms, such as EDEMA; PROTEINURIA; SEIZURES; abnormalities in BLOOD COAGULATION and liver functions.
Hypertension due to RENAL ARTERY OBSTRUCTION or compression.
A potassium sparing diuretic that acts by antagonism of aldosterone in the distal renal tubules. It is used mainly in the treatment of refractory edema in patients with congestive heart failure, nephrotic syndrome, or hepatic cirrhosis. Its effects on the endocrine system are utilized in the treatments of hirsutism and acne but they can lead to adverse effects. (From Martindale, The Extra Pharmacopoeia, 30th ed, p827)
Increased pressure within the cranial vault. This may result from several conditions, including HYDROCEPHALUS; BRAIN EDEMA; intracranial masses; severe systemic HYPERTENSION; PSEUDOTUMOR CEREBRI; and other disorders.
A condition of markedly elevated BLOOD PRESSURE with DIASTOLIC PRESSURE usually greater than 120 mm Hg. Malignant hypertension is characterized by widespread vascular damage, PAPILLEDEMA, retinopathy, HYPERTENSIVE ENCEPHALOPATHY, and renal dysfunction.
