Abstract

Thirty in-patients with chronically reduced arterial blood pressure and relevant subjective symptoms were treated over a 15-day period with oral doses of either 400 mg dimetophrine twice daily or placebo, according to a prospective, randomized, double-blind design. Systolic and diastolic blood pressures and heart rate were monitored at 5-day interval: subjective specific symptoms (scored 0 to 3 in order of increasing severity), haematology and haematochemistry were recorded before and after treatment. Both systolic and diastolic blood pressures increased significantly after dimetophrine all through the observation period. After 5 days, systolic blood pressure had already reached significantly higher values in comparison with the placebo-treated group, as did diastolic blood pressure by the 10th day. Overall, during the observation period, an increase from 82.7 +/- 1.0 to 112.3 +/- 2.1 mmHg was observed in systolic and from 54.3 +/- 1.3 to 62.7 +/- 1.4 mmHg in diastolic blood pressure with dimetophrine, whereas with placebo, systolic blood pressure increased from 80.4 +/- 1.5 to 93.7 +/- 2.9 mmHg and diastolic blood pressure remained unchanged (53.3 +/- 1.4 mmHg). Concomitantly, heart rate decreased significantly with dimetophri...Continue Reading
