Doel van het onderzoek
Inhalation of once daily double dose of inhaled tobramycin targeted to the small airways by the Akita (1x 300 mg instead of 2x 150 mg) is more effective in reducing small airways obstruction compared with standard of treatment: twice daily nebulization of standard dose using a standard nebulizer (2x 300 mg).
Onderzoeksopzet
There will be 4 study visits in the outpatient clinic. The first and third study visit will be at the start of the treatment months, the 2nd and 4th study visits will be at the end of the treatment months.
Onderzoeksproduct en/of interventie
Patients will nebulize tobramycin during 2 months in a cross-over setting: 1 month nebulization with the Akita nebulizer (once daily 300 mg tobramycin instead of twice daily 150 mg) and 1 month the recommended dose with their own nebulizer (twice daily 300 mg tobramycin). The two treatment months are seperated with a month without treatment as recommended for the treatment of a chronic pseudomonas infection.
