Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The aim of the study is to investigate and explore the most important aspects of drug-adherence in the treatment of hypertension in order to improve treatment and blood pressure control, implying that new knowledge will reduce morbidity and mortality.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Study Group

Study Group intervention: Therapeutic drug monitoring.

Group Type EXPERIMENTAL

Therapeutic drug monitoring

Intervention Type DIAGNOSTIC_TEST

Therapeutic drug monitoring will be performed.

Control Group

Control Group intervention: No intervention first 3 months. After 3 months of follow-up, half of the patients in the Control Group will be randomized to perform home blood pressure monitoring as an intervention. No intervention in the other half.

Group Type ACTIVE_COMPARATOR

Home blood pressure monitoring

Intervention Type DEVICE

Patients will perform home blood pressure monitoring at home.

Interventions

Therapeutic drug monitoring

Therapeutic drug monitoring will be performed.

Intervention Type DIAGNOSTIC_TEST

Home blood pressure monitoring

Patients will perform home blood pressure monitoring at home.
