respiratory exacerbations by 22 to 34% and an increase in the well-being of the patient were observed. With placebo, neither increase in lung function nor decrease in exacerbations was observed. The long-term inhalation of rhDNase I was found to improve, or at least maintain, lung function in patients with advanced [76] and mild lung disease[77-79]. This is a striking and important observation, as the former are at a greater risk of losing lung function [76], while the latter can hardly improve their lung functions as the baseline values are close to 100% of the predicted values [79]. Many other nonrandomized placebo-controlled studies have revealed similar data [80-83]. Additionally, Suri, et al. [84] showed in a randomized trial that inhalation of rhDNase I on alternate days is as effective as daily inhalation. Recently, a long-term trial over a period of 3 years revealed that inhalation of rhDNase I also had a positive impact on airway inflammation in CF patients [85].

In 1998, inhalation of rhDNase I was demonstrated to be safe in children younger than five years. This led to the approval of rhDNase I for the treatment of CF patients under the age of 5 [86]. Later on, studies showed that, over a long term, younger patients appear to benefit more from rhDNase I therapy than older, and often more sickly patients [68,78].

A sticky mucus known as phlegm begins to produce and increase within your bronchial tubes and you begin to wheeze, cough and struggle to breathe.
