PROBE Investigation of the Safety & Efficacy of Telmisartan (Micardis®) vs Ramipril (Altace®) Using ABPM in HTN
November 30, 2023 updated by: Boehringer Ingelheim
A Prospective, Randomised, Open-Label, Blinded-Endpoint, Parallel Group, Multicentre, Forced-Titration, 14-Week Treatment Study Comparing MICARDIS® (Telmisartan 40-80-80 mg, QD) and ALTACE® (Ramipril 2.5-5-10 mg, QD) in Patients With Mild-to-Moderate Hypertension Using Ambulatory Blood Pressure Monitoring
Demonstrate that telmisartan 80mg was at least as effective and possibly superior to ramipril 5mg & 10mg in lowering mean ambulatory DBP and SBP during the last 6 hrs of the 24-hr dosing interval in mild-to-moderate hypertensives at the end of 8 and 14 week treatment phases.

- Ability to provide written informed consent in accordance with Good Clinical Practice (GCP) and local legislation.
- Mild-to-moderate hypertension defined as a mean seated diastolic blood pressure of ≥95 mmHg and ≤109 mmHg, measured by manual cuff sphygmomanometer at Visit 2.
- Age 18 years or older (or 19 years if dictated by local State/Province policies).
- Ability to stop any current antihypertensive therapy without risk to the patient (investigator's discretion).
- 24-hour mean DBP of ≥85 mmHg at Visit 3 as measured by Ambulatory Blood Pressure Monitoring (ABPM).
