Condition(s) targeted: Healthy

Intervention: Telmisartan (Drug); Ramipril (Drug)

Phase: Phase 1

Status: Completed

Sponsored by: Boehringer Ingelheim

Summary

The main objective was to investigate the effect of concurrent dosing of 10 mg ramipril and 80 mg telmisartan on the multiple-dose pharmacokinetics of telmisartan and ramipril. Therefore the relative bioavailability of telmisartan and ramipril given in combination was determined in comparison with either telmisartan or ramipril given alone.

Clinical Details

Official title: Steady State Pharmacokinetics of 80 mg Telmisartan (Micardis), 10 mg Ramipril (Delix) or the Combination Following Repeated Oral Doses to Healthy Male and Female Volunteers (an Open-label, Randomised, Multiple-dose, Three-way Crossover Study)

Study design: Allocation: Randomized, Intervention Model: Crossover Assignment, Masking: Open Label, Primary Purpose: Treatment

Primary outcome:

AUCτ,ss (area under the concentration-time curve in plasma at steady state over a uniform dosing interval τ)

Cmax,ss (maximum measured concentration in plasma at steady state over a uniform dosing interval τ)

Secondary outcome:

Concentration of the analytes in plasma

pre-dose concentration of the analytes in plasma immediately before the administration of the next dose

tmax,ss (time from last dosing to the maximum concentration of the analytes in plasma at steady state)

Cmin,ss (minimum concentration of the analytes in plasma at steady state over a uniform dosing interval τ)

Cpre,ss (pre-dose concentration of the analytes in plasma immediately before the administration of the next dose at steady state)

Cavg (average concentration of the analytes in plasma at steady state)

λz,ss (terminal rate constant in plasma at steady state)

t1/2, ss (terminal half-life of the analyte in plasma at steady state)

MRTpo,ss (mean residence time of the analyte in the body at steady state after oral administration)

CL/F,ss (apparent clearance of the analyte in plasma at steady state after extravascular multiple dose administration)

Vz/F,ss (apparent volume of distribution of the analyte in plasma at steady state after extravascular multiple dose administration)

PTF (Peak-Trough Fluctuation)

AUC0-tz,ss (Area under the concentration-time curve of the analyte in plasma over the time interval from 0 to the time of the last quantifiable data point)

Number of patients with adverse events

Number of patients with clinically relevant changes in Vital Signs (Blood Pressure, Pulse rate)
