To compare the efficacy and safety of sacubitril/Allisartan versus amlodipine in the antihypertensive treatment of overweight/obese patients with primary hypertension
This study is a prospective, randomized, controlled, open-label trial conducted in overweight/obese patients with primary mild-to-moderate hypertension, aiming to compare the efficacy and safety of sacubitril/Allisartan versus amlodipine treatment. The study consists of two phases: a washout period (maximum 2 weeks, for patients currently receiving antihypertensive medication) and a treatment period (8 weeks). Patients already on antihypertensive therapy must complete a 2-week washout period (i.e., discontinue antihypertensive treatment), while those with no prior history of antihypertensive medication use are exempt from the washout. All patients undergo eligibility assessment against inclusion and exclusion criteria before randomization. Eligible patients are randomly assigned in a 1:1 ratio to sacubitril/Allisartan group or Amlodipine group. In sacubitril/Allisartan group, oral administration of sacubitril/Allisartan 240mg once daily for 4 consecutive weeks. If blood pressure reaches the target, the original regimen is continued; otherwise, the dose of sacubitril/Allisartan is increased to 480mg once daily for another 4 weeks of treatment. In Amlodipine group, oral administration of amlodipine 5mg once daily for 4 consecutive weeks. If blood pressure reaches the target, the original regimen is continued; otherwise, the dose of amlodipine is increased to 10mg once daily for another 4 weeks of treatment. The total treatment period is 8 weeks of oral medication. Patients will attend study visits on the day before treatment initiation (Day 0), at the end of Week 4, and at the end of Week 8 of the treatment period for efficacy and safety assessments, respectively.

Oral administration of sacubitril/allisartan 240mg once daily for 4 consecutive weeks. If blood pressure reaches the target, the original regimen is continued; otherwise, the dose of sacubitril/valsartan is increased to 480mg once daily for another 4 weeks of treatment
Amlodipine group: Oral administration of amlodipine 5mg once daily for 4 consecutive weeks. If blood pressure reaches the target, the original regimen is continued; otherwise, the dose of amlodipine is increased to 10mg once daily for another 4 weeks of treatment
