App aims to take the guesswork out of blood pressure treatment

This study tests if a smartphone app called OptiZ can help people with high blood pressure get better control of their condition. Participants use the app to track their blood pressure, medication, and side effects, and share reports with their doctor for personalized dose adjustments. The study involves adults in England who are eligible for the blood pressure drug Zestril (lisinopril). The goal is to see if the app helps lower blood pressure more effectively than standard care.
