[Therpeutic experiences with a new antitussive principle].

In the therapeutic schedule of a great sanatorium, primarily specialized in the treatment of bronchial and asthmatical diseases to the effect of a rehabilitation, a new speciality for the treatment of the symptom cough-Contrapect-was tested. Essential clinical and analytical parameters of the pulmonary function were subject to detailed examinations. The results proved that the marginal value of breathing increased and the intensity of the cough and the subjective dyspnoea were reduced. Secondary effects were not observed. The patients liked to take the drug. We also consider the product suitable for therapeutic use in general practice subsequent to clinical treatment, since, in compliance with the appropriate definition, coughing represents the main symptom of chronic bronchitis. A chronic bronchitis is assumed, if permanent cough exists over 3 months at least during a period of 2 years.
