Colobreathe® is a dry powder inhaler that is indicated for the management of Pseudomonas aeruginosa infections in patients with CF, aged 6 years and older.2
Colobreathe®’s active substance, colistimethate sodium, is an antibiotic from the polymyxin group. Polymyxins destroy Gram-negative bacterial cells such as Pseudomonas aeruginosa. They do this by causing damage to the bacterial cell membranes which ultimately leads to cell death.2
Pulmonary infection with P. aeruginosa is the leading cause of morbidity and mortality in patients with CF.3
