The purpose of this study is to explore the effectiveness, safety, and cost-effectiveness of pharmacists implementing the Drug Treatment Management Pathway in the treatment of hypertension patients. This trial is a prospective, multi-center, randomized, controlled study. We plan to enroll 420 patients with primary hypertension who are over 18 years old and whose blood pressure control is not up to standard. Qualified participants who meet the inclusion and exclusion criteria were randomly divided into an intervention group of 280 cases and a non intervention group of 140 cases in a 2:1 ratio.
