The objective of the present study was to investigate the dose-dependent bronchodilator efficacy and duration of action of the newly developed antimuscarinic agent tiotropium bromide in patients with chronic obstructive pulmonary disease (COPD). In a randomized, double-blind, placebo-controlled, crossover design, patients inhaled single doses of 10-80(More)
Preclinical studies with Ba 679 Br have demonstrated a significantly longer duration of action than ipratropium bromide. Following inhalation of single doses, no systemic antimuscarinic effects were noted at doses likely to be bronchodilating in man. The objective of the present pilot-study of Ba 679 Br was to establish the dose-range for its(More)
The objective of this study was to compare the long-term safety of a fixed combination of fenoterol hydrobromide (50 microg) and ipratropium bromide (20 microg) delivered using a metered dose inhaler (MDI) formulated with a non-chlorinated propellant, hydrofluoroalkanel34a (HFA-MDI), with delivery using the conventional chlorofluorocarbon propellant(More)
A randomized double-blind cross-over study was performed to compare the bronchodilator effects of a fenoterol/ipratropium bromide combination (Berodual) when inhaled as a dry powder and by metered dose inhaler (MDI) in an equal doses (fenoterol 100 micrograms + ipratropium bromide 40 micrograms). Thirty-eight patients (29 male, 9 female, mean age 53 years)(More)
The efficacy and safety of a novel fenoterol/ipratropium bromide metered-dose inhaler (MDI) formulated with a non-chlorinated propellant, HFA134a, has been compared with placebo and the conventional chlorofluorocarbon (CFC)-containing fenoterol/ipratropium bromide inhaler (Berodual) in asthmatic patients. Fifty-two patients were enrolled in two centres. The(More)
Zatebradine, a member of a novel class of drugs called 'sinus node inhibitors', is a specific heart rate lowering drug suitable for the treatment of stable angina pectoris. Animal studies showed that relatively high intravenous doses of zatebradine contracted guinea-pig airways by a histamine-like mechanism. Therefore, the objective of the present study was(More)
At our institute a total artificial heart is being developed. It is directly actuated by a linear drive in between two ventricles, which comprise membranes to separate the drive and blood flow. A compliance chamber (CC) is needed to reduce pressure peaks in the ventricles and to increase the pump capacity. Therefore, the movement of the membrane is(More)
