Study Endpoints
Primary Endpoints
Maximum Observed Plasma Concentration (Cmax)
Day 1 and Day 9

Characterization of Cmax, taken directly from the individual concentration-time curve after single dose or multiple dose.

Time to Reach Maximum Observed Concentration (Tmax)
Day 1 and Day 9

Characterization of Tmax, taken directly from the individual concentration-time curve after single dose or multiple dose.

Area Under the Concentration-time From Zero to Infinity (AUCinf)
Day 1

Characterization of AUCinf (single dose). Area under the concentration time curve from time zero extrapolated to infinity. AUC(0-∞) is estimated by AUC(last) + Clast/λz where Clast is the last observed quantifiable concentration.

Area Under the Concentration-time From Time 0 to 12 Hours Post-dose [AUC(0-12)]
Day 1 and Day 9

The AUC(0-12) of aclidinium bromide and its metabolites after single dose of aclidinium bromide in healthy Chinese participants is investigated. Description of the AUC(0-12), partial area under the concentration- time curve in the dose interval after single dose or multiple dose.

Area Under the Concentration-time From Zero to the Last Quantifiable Concentration (AUClast)
Day 1 and Day 9

Characterization of AUClast, taken directly from the individual concentration-time curve after single dose or multiple dose.

Half-life Associated With Terminal Slope of a Semi-logarithmic Concentration-time Curve (t½λz)
Day 1 and Day 9

Characterization of t½λz, of aclidinium bromide and its metabolites after single and multiple doses of aclidinium bromide in healthy Chinese participants.

Apparent Total Body Clearance From Plasma After Extravascular Administration (CL/F)
Day 1 and Day 9

Characterization of CL/F, of aclidinium bromide after single and multiple doses of aclidinium bromide in healthy Chinese participants.

Volume of Distribution (Apparent) Following Extravascular Administration Based on Terminal Phase (Vz/F)
Day 1 and Day 9

Characterization of Vz/F, of aclidinium bromide after single and multiple doses of aclidinium bromide in healthy Chinese participants.

Mean Residence Time of the Unchanged Drug in the Systemic Circulation (MRTinf)
Day 1

Characterization of MRTinf, of aclidinium bromide after single dose of aclidinium bromide in healthy Chinese participants.

Minimum Observed Drug Concentration (Cmin)
Day 1 and Day 9

Characterization of Cmin, taken directly from the individual concentration-time curve after single dose or multiple dose.

Average Drug Concentration Over a Dosing Interval (Cavg)
Day 9

Characterization of Cavg, of aclidinium bromide and its metabolites after multiple doses of aclidinium bromide in healthy Chinese participants.

Accumulation Ratio for Cmax [Rac(Cmax)]
Day 9

Characterization of Rac(Cmax), of aclidinium bromide and its metabolites after multiple doses of aclidinium bromide in healthy Chinese participants. Rac(Cmax) is caculated as a ratio for Cmax estimated as (ratio of Css,max on Day 9/Cmax on Day 1).

Accumulation Ratio for Cmin (Rac[Cmin])
Day 9

Characterization of Rac(Cmin), of aclidinium bromide and its metabolites after multiple doses of aclidinium bromide in healthy Chinese participants. Rac(Cmin) is calculated as ratio for Cmin estimated as (ratio of Css, Cmin on Day 9/ Cmin on Day 1)

Accumulation Ratio for AUCτ (Rac[AUC])
Day 9

Characterization of Rac(AUC), of aclidinium bromide and its metabolites after multiple doses of aclidinium bromide in healthy Chinese participants. Rac(AUC), calculated as ratio of AUC(0-12) on day 9 and AUC0-12 on Day 1.

Fluctuation Index During a Dosing Interval (%Fluc)
Day 9

Characterization of %Fluc, of aclidinium bromide and its metabolites after multiple doses of aclidinium bromide in healthy Chinese participants. The %Fluc index is estimated as 100 x (Cmax- Cmin)/Cav.
