What is Clorpres

Chlorthalidone

The Generic name of this drug

Treatment Summary

Chlorthalidone is a drug used to treat high blood pressure and swelling caused by heart failure or kidney problems. It works by preventing the absorption of salt and water in the kidneys, which helps to reduce the pressure in the arteries and reduce swelling. Chlorthalidone is often used as the first treatment for uncomplicated hypertension because it has been shown to reduce the risk of stroke, heart attack, heart failure, and other cardiovascular issues. It has also been shown to have additional benefits, such as reducing platelet aggregation and vascular permeability, and promoting angiogenesis.

Effectiveness

How Clorpres works in the body

Chlorthalidone works by preventing the reabsorption of sodium and chloride in the kidneys. This reduces the amount of fluid and salt in your blood, which causes your blood pressure to drop. It also helps reduce platelet aggregation and vascular permeability, as well as encouraging new blood vessel formation. These effects may help reduce your risk of cardiovascular disease.

Clorpres for High Blood Pressure

I have experienced many negative side effects while taking this medication, such as needing to take laxatives nearly every night just to go to the bathroom. My mouth is always dry, my eyes are dry, and my vision gets blurry. I've spoken with my doctor about these problems, but they simply advised me to take a stool softener. In my opinion, I think this medication should be discontinued for me.

Clorpres for Extremely High Blood Pressure

I've been on clonidine for over a year to manage my high blood pressure. It worked great at first, but now I have to take it four times per day and it barely does anything. The side effects are also really awful-- dizziness, dry mouth and eyes, migraines, and vivid dreams. I can't wait to be taken off this medication.

Patient Q&A Section about clorpres

These questions and answers are submitted by anonymous patients, and have not been verified by our internal team.

Is clonidine still available?

"Chlorthalidone/clonidine is no longer available in the United States."

Answered by AI

Is chlorthalidone the same as clonidine?

"This medication contains 2 medications: clonidine and chlorthalidone. Clonidine works by controlling nerve impulses along certain body nerve pathways. As a result, it relaxes blood vessels so that blood passes through them more easily. The chlorthalidone in this combination is a diuretic (water pill) that helps reduce the amount of water in the body by increasing the flow of urine."

Answered by AI

Why is clonidine used for ADHD?

"Clonidine affects the part of the brain that controls attention and impulsive behavior in people with ADHD, though its precise mechanism is not yet known."

Answered by AI

What is the side effects of clonidine?

"Signs of an impending heart attack include anxiety, chest pain, confusion, decreased urine output, dilated neck veins, a fast heartbeat, and general discomfort."

MediBeacon Transdermal GFR System for Heart Failure

18+
All Sexes
New York, NY

The goal of this clinical trial is to evaluate the accuracy and feasibility of transdermal glomerular filtration rate (tGFR) assessment using relmapirazin (Lumitrace) and the MediBeacon tGFR system compared to plasma clearance measurement of GFR in adults with heart failure. The main question it aims to answer is the comparison of the transdermal-derived GFR for each participant using the MediBeacon tGFR to their nGFRBSA measurement. Participants will participate in a Screening visit that will take place within 15 days of the scheduled administration of Lumitrace and iohexol. On dosing day, participants will have the tGFR reusable sensor with disposable adhesive ring placed on their chest, and the MediBeacon Transdermal GFR System initiated to collect background fluorescence. Following an injection of Lumitrace and iohexol and the initiation of GFR assessments, participants will be followed at the study center for 10-24 hours. All participants will participate in a follow-up phone call approximately 7 days after the last exposure to Lumitrace and iohexol. Researchers will analyze the results to compare the tGFR values to the nGFRBSA measurements for each participant.

Clinical Decision Support Tool for Heart Failure

18 - 85
All Sexes
Boston, MA

This study is an investigator-initiated, cluster-randomized implementation trial evaluating a large language model (LLM)-based clinical decision support (CDS) tool designed to improve guideline-directed medical therapy (GDMT) for adult patients with heart failure seen in outpatient cardiology clinics at Mass General Brigham. For eligible heart failure encounters, the CDS tool reviews existing electronic health record (EHR) data, including diagnoses, medications, vital signs, laboratory results, and recent notes, and generates brief, clinician-facing messages suggesting opportunities to initiate or optimize GDMT and highlighting relevant safety considerations. Messages are delivered to cardiology providers via Epic InBasket and/or institutional email prior to scheduled visits. The tool is advisory only and cannot place orders or change medications automatically; all treatment decisions remain at the discretion of the treating clinician and patient. Cardiology providers are assigned at the provider/clinic level to early implementation of the CDS tool versus usual care (no messages) during the initial phase. The primary outcome is GDMT optimization within 30 days of an index visit. Secondary outcomes include feasibility of CDS generation and delivery and a 30-day safety composite (e.g., heart failure hospitalization, acute kidney injury, hyperkalemia, hypotension or bradyarrhythmia plausibly related to GDMT).

FRAME for Heart Failure

18+
All Sexes
Cornwall, Canada

Heart failure is a high-risk, chronic condition that impacts patients' mental health. Approximately 50% of heart failure patients experience comorbid mental health conditions, such as stress, depression and anxiety, which affect their day-to-day lives. Despite this interconnection, the integration of mental health awareness and support into cardiac care remains limited. To address this gap, the FRAME (Foundation, Recognition, Awareness, Management, Engagement) intervention was co-designed by researchers, healthcare providers, health system decisionmakers, and patient partners. This pilot study evaluates the feasibility of implementing the FRAME intervention in pilot clinical sites within two health regions in Ontario, Canada, including team-based family medicine clinics, cardiac rehabilitation/specialist clinics, and emergency departments. Utilizing a pretest-posttest hybrid 1 model intervention design, this study evaluates process indicators and patient-focused outcomes through surveys and semi-structured qualitative interviews. Findings from this study will inform a future large scale cohort study and scalable integration of the FRAME tool into existing cardiac care pathways to enhance mental health awareness and support among heart failure patients.

Dapagliflozin for Heart Failure

18 - 85
All Sexes
New Haven, CT

The overall objective of this study is to determine whether the addition of SGLT2 inhibitors to usual care in hospitalized patients with heart failure associated acute kidney injury is safe and efficacious. Investigators will assess if SGLT2 inhibition improves a composite cardio-renal outcome (mortality, dialysis, AKI progression, decongestion metrics, heart failure symptoms). Secondary objectives of this study are to compare individual components of the composite outcome as well as changes in biomarkers of kidney injury, inflammation, repair and oxidative stress between those exposed to the SGLT2 inhibitor vs placebo.

All Sexes
Cambridge, Canada

The goal of this clinical trial is to learn if the drug finerenone (Karendia) can improve heart function in participants who are at risk for heart and kidney disease. The main question it aims to answer is whether adding finerenone to standard-of-care heart failure medical therapies will beneficially alter the heart structure and function of people who have risk factors for heart and kidney complications and whose left side of the heart is enlarged. The researchers will compare finerenone to a placebo (a look-alike substance that contains no drug) to see if finerenone improves heart structure and function. Participants will: * take a finerenone or a placebo tablet once a day for 12 months * have a cardiac magnetic resonance imaging (cMRI; a safe, non-invasive scan to measure heart mass, stiffness and function) test at the beginning of the study and 12 months later * visit the clinic after one, three, six and twelve months to assess overall health and/or perform blood or urine tests

Lakeland, FL

The goal of this clinical trial is to learn if increasing the dose of diuretics to achieve a higher urine sodium target produces better clinical results when treating patients hospitalized with acute heart failure when compared to lower urine sodium target and standard of care. The main questions it aims to answer are: 1. Does targeting a higher urine sodium goal achieve greater natriuresis and diuresis? 2. Does targeting a higher urine sodium goal reduce frequency of hospital readmissions? 3. Does targeting a higher urine sodium goal reduce hospital length of stay? Researchers will compare natriuresis-guided arms with standard of care to see if targeting higher natriuresis goals improves significantly over current practice. Participants will submit urine samples at routine intervals after being given diuretics to evaluate urine sodium concentration. If urine sodium is low then diuretic dose will be increased.
