|Official Title:||An Open, Single Centre, Single and Repeated Dose Study to Investigate the Pharmacokinetic Profile of Roflumilast and Roflumilast N-oxide After Administration of 500 μg Dose of Roflumilast in Healthy Chinese Subjects|
- To determine the pharmacokinetic profiles after single and repeated dose of roflumilast 500 µg administered to healthy Chinese subjects. [ Time Frame: Period I: single dose, PK-Investigation over 8 days, Period II: repeated dose for 14 days, PK-Investigation on days 14 and 15 ] [ Designated as safety issue: No ]PK samples at pre-dose, 0.25h, 0.5h, 0.75h, 1h, 1.5h, 2h, 2.5h, 3h, 4h, 5h, 6h, 8h, 10h, 12h, 16h and 24h, 36h, 48h, 72h, 96h, 120h, 144h and 168h post dose after single dose and at the time points pre-dose, 0.25h, 0.5h, 0.75h, 1h, 1.5h, 2h, 2.5h, 3h, 4h, 5h, 6h, 8h, 10h, 12h, 16h and 24h after administration of a repeated dose
- The safety and tolerability of single and repeated dose roflumilast 500 µg will be evaluated in terms of adverse event, ECG, blood pressure, pulse rate, and clinical laboratory tests. [ Time Frame: During screening, clinical part and final check ] [ Designated as safety issue: No ]
