Condition(s) targeted: Hypertension

Intervention: Telmisartan (Drug); Valsartan (Drug); Placebo (Drug)

Phase: Phase 4

Status: Completed

Sponsored by: Boehringer Ingelheim

Summary

The primary aim of the trial is to compare telmisartan 80 mg to valsartan 160 mg in lowering diastolic blood pressure in patients who missed a dose of their medication, as measured by ABPM (change from baseline in mean DBP over 24 hours), and to compare telmisartan 80 mg to valsartan 160 mg in lowering DBP during the last six hours of the dosing interval at the end of a 6 to 8-week treatment period, as measured by ABPM (change from baseline)

Clinical Details

Official title: A Prospective, Randomised, Double-blind, Double-dummy Trial to Compare the Efficacy of Micardis (Telmisartan) (80 mg p.o. Once Daily) and Valsartan (160 mg p.o. Once Daily) in Patients With Mild-to-moderate Hypertension After Missing One Dose Using Ambulatory Blood Pressure Monitoring

Study design: Allocation: Randomized, Intervention Model: Parallel Assignment, Masking: Double-Blind, Primary Purpose: Treatment

Primary outcome:

Change in 24 hour mean Diastolic blood pressure (DBP) after a missed dose

Change in mean DBP during the last 6 hours of the 24 hour dosing interval

Secondary outcome:

Change in 24-hour mean systolic blood pressure (SBP) after a missed dose

Change in mean SBP during the last 6 hours of the 24-hour dosing interval

Change in pulse pressure (PP)

Change in 24-hour mean DBP after an active dose of study medication

Change in 24-hour mean SBP after an active dose of study medication

Change in mean seated trough SBP/DBP/PP in- clinic manual cuff sphygmomanometer after a missed dose

Change in the mean seated trough SBP/DBP/PP in- clinic manual cuff sphygmomanometer after an active dose of study medication

Responder rate measured by ABPM after a missed dose of study medication

Responder rate measured by ABPM after an active dose of study medication

Responder rate in- clinic manual trough cuff measurements after a missed dose of study medication

Responder rate in- clinic manual trough cuff measurements after an active dose of study medication

Number of patients with adverse events

Change in 24-hour Pulse Pressure (PP) after a missed dose
