Study summary

To study antihypertensive efficacy of 12 weeks of Losartan based therapy Resilo (Losartan) and Resilo-H (Losartan+ Hydrochlorothiazide) in uncontrolled hypertensive and diabetic hypertensive patients.

Read the detailed description

200 hundred Subjects will be treated with a dose escalation regimen to achieve a target blood pressure. Subjects with mild hypertension at baseline will be started with losartan 50 mgs and those with severe hypertension will be started with losartan H 100/25. After 6 weeks they will titrated if goal blood pressure not achieved. For Mild hypertensive group this will be with losartan H 100/25 and for severe hypertensive group this will by addition of amlodipine 5 mg to regime. Subjects with mild hypertension and diabetes at baseline will be started with losartan H 50/12.5 mg and those with severe hypertension with diabetes will be started with losartan H 100/25. After 6 weeks they will be titrated if goal blood pressure not achieved. For Mild hypertensive-diabetic group this will be with Resilo H 100/25 and for severe hypertensive group this will by addition of amlodipine 5 mg to regime.

Target Blood Pressure is systolic \< 140 mmhg and diastolic \< 90 mmHg if age \< 60 years and systolic \< 150 mmHg and diastolic \< 90 mmHg if age >60 years.

Terms in these criteria, in plain language(1)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.
