Source: ClinicalTrials.gov · Last updated 18 Mar 2026
Brief summary (registry, in English)
This is a clinical study to improve the regularity of medication intake for high blood pressure. Adult women and men who are over 50 years old, who have received a prescription drug for high blood pressure from MediService, and who have to take at least 4 tablets per day (of which at least 1 dose of medication per day is for high blood pressure) can participate in this study. The investigators intend to examine whether Collabree, a mobile phone application, is effective in supporting patients with hypertension to more successfully following their therapy plan in order to improve the regularity of medication intake. The study includes a 90-day intervention phase and a 90-day follow-up. The study does not require any therapy adjustments and no visits to a study center are necessary. The participants conduct the study independently at home. Participants will also fill out questionnaires. Participants are randomly assigned to one of 3 groups in a ratio of 1: 1: 1. Two of these groups will receive the Collabree mobile phone application.
