Brief summary: Hypertension guidelines recommend the application of ambulatory blood pressure monitoring in the diagnosis and treatment of patients with hypertension. Subtypes of hypertension such as nocturnal hypertension can be found through ambulatory blood pressure monitoring. Previous studies have reported that the prevalence of nocturnal hypertension, even isolated nocturnal hypertension, is higher in patients with chronic kidney disease, and it is associated with adverse events such as cardiovascular events and progression of renal dysfunction. However, the benefit of controlling nocturnal hypertension in patients with chronic kidney disease is unclear. In this study, a total of 200 patients with chronic kidney disease and isolated nocturnal hypertension will be enrolled. Patients will be randomly divided into two treatment groups: the active antihypertensive treatment group and the placebo treatment group (1:1). The antihypertensive treatment group will be treated with arotinolol or amlodipine and clonidine to control nocturnal blood pressure, while the control group will be treated with the corresponding placebos. Randomized patients will be followed up for 2 years to evaluate the effect of controlling isolated nocturnal hypertension on the progression of chronic kidney disease in terms of EPI-estimated glomerular filtration rate (eGFR) decline and change in proteinuria.

Exclusion Criteria:

* Secondary hypertension related to suspected or confirmed renal artery stenosis or adrenal gland disorders;
* Poor glycemic control (HbA1c \> 12%);
* Orthostatic hypotension (a decrease in blood pressure of \>20/10 mmHg within 3 minutes of standing from a sitting position);
* Women who are pregnant or breastfeeding at the time of enrollment, or not employing contraception of reproductive age;
* NYHA (New York Heart Association) Class III-IV congestive heart failure at the time of enrollment;
* History of myocardial infarction, unstable angina, acute heart failure, stroke, transient ischemic attack (TIA), or cerebral hemorrhage within the 12 weeks prior to enrollment;
* Underwent coronary revascularization (Percutaneous Coronary Intervention \[PCI\] or Coronary Artery Bypass Grafting \[CABG\]), or valve repair/replacement within the 12 weeks prior to enrollment, or planned to undergo any of the aforementioned surgical procedures after randomization;
* Any other serious diseases outside the renal and cardiovascular domains, including but not limited to malignancies, with an expected survival of less than 2 years based on the investigator's clinical judgment;
* Presence of active malignancy requiring pharmacological treatment;
* AST (Aspartate Aminotransferase) or ALT (Alanine Aminotransferase) levels \>3 times the upper limit of normal (ULN);
* Total bilirubin \>2 times ULN. Patients with Gilbert's syndrome who exhibit isolated bilirubin elevation do not need to be excluded;
