A study protocol for a double-blind randomised control trial of hypotensive treatment in elderly hypertensive patients has been tested in a number of pilot centres throughout Europe. It was shown that this study is possible from the logistic point of view. In these elderly patients, hydrochlorothiazide + triamterene treatment with or without methyldopa, maintained a significant hypotensive effect in the absence of major electrolyte disturbances. The initiation of hypotensive therapy did not provoke an excess of cardiovascular complications. The influence of hypotensive therapy on the general well-being and on the morbidity and the mortality of elderly patients with high blood pressure, is thereby being assessed. The study will continue for 5 years and other centres are invited to join.

D010919	Placebos	Any dummy medication or treatment. Although placebos originally were medicinal preparations having no specific pharmacological activity against a targeted condition, the concept has been extended to include treatments or procedures, especially those administered to control groups in clinical trials in order to provide baseline measurements for the experimental protocol.	Sham Treatment
D011188	Potassium	An element in the alkali group of metals with an atomic symbol K, atomic number 19, and atomic weight 39.10. It is the chief cation in the intracellular fluid of muscle and other cells. Potassium ion is a strong electrolyte that plays a significant role in the regulation of fluid volume and maintenance of the WATER-ELECTROLYTE BALANCE.
