Ventilation effects of fenoterol powder and freon-propelled aerosol in patients with asthma.
The efficacy of fenoterol powder (Berotec, Boehringer-Ingelheim) was investigated in ten patients with moderate or severe asthma. Double-blind comparison to placebo powder showed a significant difference (p less than 0.05) between 30 to 180 min after a single dose of 0.2 mg. There was no difference between fenoterol powder and aerosol (0.2 mg). No adverse effects were encountered.
