Summary A randomized cross-over trial was undertaken on 21 occupationally active persons who had a stable mild or moderate hypertension with the purpose of comparing the effect of a beta-adreno-receptor blocking agent (atenolol) with that of a calcium channel inhibitor (nifedipine). The doses recommended by the manufactures were used. Atenolol (100 mg) given once a day resulted in a marked hypotensive effect at rest as well as during exercise, the compliance was satisfactory, and the hemodynamic changes were not reflected in unfavourable side effects during muscular exercise or in the subjects own personal assessment of fatigue during the exercise tests which ranged in energy expenditure from about three to six times the resting level. However, unfavourable, modest side effects occurred in two subjects during atenolol medication to the extent that they wanted to terminate the study. Nifedipine therapy with doses of 10 mg, three times a day, resulted in a modest, but statistically insignificant reduction in arterial blood pressure, which contrasts with previous published results. It is suggested that the modest effect is caused or related to the poor compliance and a daily dose that was quantitatively too small. No unfavourable side effects were seen during muscular efforts when the subjects were on nifedipine medication.
