Therapeutic Adherence in Uncontrolled Arterial Hypertension

Status Recruiting

Clinical Trial Summary

In hypertension, highly prevalent, up to 10-15% of hypertensive patients have uncontrolled blood pressure despite being treated with ≥3 drugs, which is known as resistant hypertension. Resistant arterial hypertension, together with difficult-to-control hypertension, has a worse cardiovascular prognosis than controlled hypertension. In addition, data on therapeutic adherence in arterial hypertension show that 1 in 2 hypertensive patients do not fully or partially comply with the indicated therapeutic prescription. The determination of antihypertensive drugs or their metabolites in urine seems to be a good indicator of therapeutic adherence. On the other hand, the implementation of a specific program to improve knowledge of the disease and its risks and promote therapeutic adherence could improve the control of hypertension and reduce the associated morbidity and mortality.

Clinical Trial Description

Objective: To assess whether the implementation of a specific action plan to improve adherence for 3 months results in reduced peripheral 24h-systolic blood pressure (SBP) in patients with resistant hypertension (RH) or uncontrolled hypertension with 2 antihypertensive drugs.

Method: interventional, prospective, randomized, controlled, parallel groups, open study of a cohort of 150 consecutively recruited patients with RH (office SBP ≥140mmHg and/or diastolic blood pressure ≥90mmHg despite treatment with ≥3 drugs at appropriate doses, one diuretic) or patients with uncontrolled hypertension with 2 antihypertensive drugs, with ambulatory 24h-BP ≥130 and / or 80mmHg. The partially or completely non-adherent patients (confirmed by determination of antihypertensive drugs in urine) will be randomized (1: 1) to receive a specific program to improve adherence (intervention group) or routine follow-up (control group), with office BP measurement and determination of antihypertensive drugs in urine at pre-randomization, 3, 6 and 12 months; peripheral and central 24h-ambulatory BP monitoring will be performed at pre-randomization, at 3 and 12 months. ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
