About this study
Official title: Effect of Potassium Losartan With Bedtime Dosing on Chronic Kidney Disease Patients With Nondipping Blood Pressure Pattern
Nondipping blood pressure (BP) pattern is a potential independent risk factor for chronic kidney disease (CKD). Whether bedtime administration of potassium losartan has benefit for anti-hypertension and the prognosis of CKD patients is not clear. Patients with nondipping BP pattern or dipping BP pattern were enrolled in this study, and the patients with nondipping BP pattern were randomly divided into two groups and treated with bedtime or awakening doses of potassium losartan.
Read the detailed description
Patients with nondipping BP pattern or dipping BP pattern were enrolled in this study, and the patients with nondipping BP pattern were randomly divided into two groups and treated with bedtime or awakening doses of potassium losartan. Any patients who had any antihypertension medication at bedtime would withdrawal the drugs for 2 weeks before ABPM. Patients with nondipping BP were then randomly divided into two groups and received a bedtime or awakening dose of potassium losartan. Patients with dipping BP were called the dipper group, while the patients with nondipping BP were called the awakening dose group or bedtime dose group, according to the time of drug administration.

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.
Nondipping blood pressure (BP) pattern is a potential independent risk factor for chronic kidney disease (CKD). Whether bedtime administration of potassium losartan has benefit for anti-hypertension and the prognosis of CKD patients is not clear. Patients with nondipping BP pattern or dipping BP pattern were enrolled in this study, and the patients with nondipping BP pattern were randomly divided into two groups and treated with bedtime or awakening doses of potassium losartan.

Questions about this trial
What is this clinical trial studying?
A study testing potassium losartan in people with Chronic Kidney Disease Patients, run by Fifth Affiliated Hospital, Sun Yat-Sen University at 1 site in China.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 4 inclusion and 12 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: status not confirmed, as of the sponsor's last update on 27 Jul 2018. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in China. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
Results are not available in the source record.
How can a doctor refer a patient or contact the research team?
Contact Cheng Wang, Doctor (18520762959, wt770716@163.com), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
renal events and Cardiovascular events (time frame: 5 years). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT03603938, which also lists 29 linked publications.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 27 Jul 2018.
