[Long-term studies on the beta blocker talinolol (cordanum) with special reference to side effects]

224 patients with coronary heart disease, hypertension, disturbances of cardiac rhythm or hyperkinetic heart syndrome were treated with the cardioselective beta-blocker Talinolol (Cordanum) for a period up to 3 years. In 239 examinations in intravenous or peroral application of this medicament we controlled among others the appearance of side effects. This test was carried out with the help of standardised questionings and clinical controls. Apart from registrations of ECG and blood pressure clinico-chemical investigations were included and in the long-term experiment also tests by dermatologists, otorhinolaryngologists and ophthalmologists. In the total number of patients the proportion of side appearances was 17,6%, in the long-term experiment (100 patients with on an average 12.9 months) 7%. The symptoms most frequently cited in the initial phase, such as fatigue, weakness, insomnia and nausea receded within 4 weeks apart from few exceptions. There did not appear any essential bradycardic disturbances of the cardiac rhythm, just as little were references to disadvantageous reactions in the sense of a practolol syndrome.
