- Primary Outcome Measures
Name Time Method Area under the concentration-time curve of telmisartan in plasma at steady state over a uniform dosing interval τ (AUCτ,ss) up to 15 days after first administration of study drug Maximum measured concentration of telmisartan in plasma at steady state over a uniform dosing interval τ (Cmax,ss) up to 15 days after first administration of study drug
- Secondary Outcome Measures
Name Time Method Pre-dose concentration of the analyte in plasma immediately before the administration of the next dose N (Cpre,N) pre-dose on days 2-9 Time from last dosing to the maximum concentration of the analyte in plasma at steady state (tmax,ss) up to 144 hours after last administration of study drug AUCτ,ss for amlodipine up to 15 days after first administration of study drug Cmax,ss for amlodipine up to 15 days after first administration of study drug Maximum measured concentration of the analyte in plasma (Cmax) up to 12 hours after first administration of study drug Time from dosing to maximum measured concentration on plasma (tmax) up to 12 hours after first administration of study drug Area under the plasma concentration-time curve over a uniform dosing interval τ after administration of the first dose; corresponds to AUC0-24h (AUCτ,1) up to 12 hours after first administration of study drug Minimum concentration of the analyte in plasma at steady state over a uniform dosing interval τ (Cmin,ss) up to 144 hours after last administration of study drug Terminal rate constant in plasma at steady state (λz,ss) up to 144 hours after last administration of study drug Terminal half-life of the analyte in plasma at steady state (t1/2, ss) up to 144 hours after last administration of study drug Mean residence time of the analyte in the body at steady state after oral administration (MRTpo,ss) up to 144 hours after last administration of study drug Apparent clearance of the analyte in plasma at steady state after extravascular multiple dose administration (CL/F,ss) up to 144 hours after last administration of study drug Apparent volume of distribution of the analyte in plasma at steady state after extravascular multiple dose administration (Vz/F,ss) up to 144 hours after last administration of study drug Accumulation ratio of the analyte in plasma based on AUC over a uniform dosing interval after the first and last doses (RA, AUC) up to 15 days after first administration of study drug Accumulation ratio of the analyte in plasma based on Cmax over a uniform dosing interval after the last and first doses (RA,Cmax) up to 15 days after first administration of study drug Number of subjects with adverse events up to 80 days Assessment of tolerability by investigator on a 4-point scale within 14 days after last trial procedure
