[Treatment of hypertension with tenormin 100 (atenolol). A general practice study (author's transl)].

The effect and tolerance of a single daily tablet of Tenormin 100 in the treatment of essential hypertension was investigated in a private practice multicenter trial. 4083 Patients with mild to moderate essential hypertension (age range 15--89 years) were treated for four weeks. According to WHO criteria 83.4% of all patients were clearly hypertensive. At the end of the treatment 88.8% were under satisfactory control. The treatment was generally well tolerated. No hitherto unknown side effects occurred. The global therapeutic success rating, also taking into account the side effects, was confirmed mathematically and showed a success rate of 82% for Atenolol in this trial.
