Design outcomes
Primary
| Measure | Time frame |
|---|---|
| The following pharmacokinetic parameters will be calculated: AUC0 till 8-12 (area under the curve from 0 till 8-12 h) | — |
Secondary
| Measure | Time frame |
|---|---|
| The following pharmacokinetic parameters will be calculated: actual dose (dose minus remainder in inhaler after inhalation), Cmax (maximum plasma concentration), Tmax (time to maximum plasma concentration), Ka (absorption rate constant), T1/2 el (terminal elimination half-life), CL/F (clearance following pulmonary administration (F= bioavailability)). Local tolerability of DP Tobramycin is determined by scoring adverse events, specifically coughing, and lung function measurement. | — |
