[First experiences with BS 100-141, a new antihypertensive substance].

The administration of a new guanidine derivate, BS 100-141, to 20 patients resulted in a statistically highly significant reduction of blood pressure. A comparative clinical trial of BS 100-141 and alpha-methyl-DOPA showed BS 100-141 to be more efficient in lowering the arterial pressure than alpha-methyl-DOPA, especially when the drug was used in the second period of treatment. In the majority of the patients treated with BS 100-141 a slight increase in blood glucose concentration, not exceeding the upper limits of normal values, was found.
