Condition(s) targeted: Healthy

Intervention: telmisartan (Drug); ASA/ER-DP (Drug)

Phase: Phase 1

Status: Completed

Sponsored by: Boehringer Ingelheim

Summary

To investigate the relative bioavailability of telmisartan respectively of dipyridamole after concomitant administration of 80 mg telmisartan in Micardis® and 25 mg acetylsalicylic acid (ASA)/200 mg extended release (ER) dipyridamole (DP) in Aggrenox® (Test 1) relative to ER-DP in Aggrenox® alone (Reference 1), respectively relative to telmisartan in Micardis® alone (Reference 2). To investigate the relative bioavailability of dipyridamole respectively of telmisartan administered as 25 mg ASA/200 mg ER-DP 30 minutes after intake of 80 mg telmisartan (Test 2) relative to dipyridamole in Aggrenox® alone (Reference 1), respectively relative to telmisartan in Micardis® alone (Reference 2).

Clinical Details

Official title: Relative Bioavailability of Telmisartan in Micardis® and of Dipyridamole in Aggrenox® After Co-administration Compared to the Bioavailability of Telmisartan Respectively of Dipyridamole After Oral Administration of 80 mg Telmisartan Respectively of 25 mg ASA/200 mg Extended-release Dipyridamole Alone. An Open-label, Randomised, Single-dose, Four-way Crossover Study in 24 Healthy Female and Male Subjects

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

Primary outcome:

AUC0-∞ (area under the concentration time curve in plasma from 0 extrapolated to infinity)

Cmax (maximum concentration in plasma)

Secondary outcome:

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

AUCt1-t2 (Area under the concentration time curve in plasma over the time interval t1 to t2)

tmax (time from dosing to the maximum concentration of the analytes in plasma)

λz (terminal rate constant in plasma)

t1/2 (terminal half-life of the analytes in plasma)

MRTpo (mean residence time of the analyte in the body after p.o. administration)

CL/F (apparent clearance of the analytes in the plasma after extravascular administration)

Vz/F (apparent volume of distribution during the terminal phase λz following an extravascular dose)

Number of subjects with adverse events

Number of subjects with clinically significant findings in vital signs

Number of subjects with clinically significant findings in 12 lead ECG

Number of subjects with clinically significant findings in laboratory tests

Assessment of tolerability by the investigator on a 4-point scale
