Abstract
A double-blind parallel study in patients with asthma compared the safety and efficacy of saline-isoproterenol (SI) and acetylcysteine-isoproterenol (AI), when administered at home as an aerosol, over a one-week period, using a conventional nebulizer compressor.
Measurements of pulmonary function revealed statistically significant differences between the two therapies for FEV1 and FVC in favour of AI. In the group treated with AI, the average sputum viscosity after six days of treatment was significantly less than pre-treatment values, or when compared to the results with SI treatment.
No serious side-effects were reported during treatment with either therapy. These results indicate that acetylcysteine combined with a bronchodilator, such as isoproterenol, may be safe and of significant value in the treatment of patients with asthma who are also sputum producers.
