Treatment Summary

Triamterene is a medication used to treat high blood pressure. It helps the body get rid of extra sodium and water while also preserving potassium. Taking this medication can increase the risk of high potassium levels in the blood, called hyperkalemia. Triamterene was approved by the FDA in 1964 and is used alone or in combination with other diuretics to enhance its effects. It is also found in a combination product with hydrochlorothiazide to treat high blood pressure or edema in people who become low on potassium when taking hydrochlorothiazide by itself.

Effectiveness

How Triamterene Affects Patients

Triamterene is a drug used to treat high blood pressure and swelling. It works by blocking the body from absorbing too much salt and preventing the loss of potassium in the urine. This can lead to high levels of potassium in the blood (hyperkalemia), which can cause an irregular heartbeat. Triamterene also affects the kidney's ability to filter out other substances like sodium, magnesium, uric acid, and creatinine. It does not affect calcium excretion. When used with hydrochlorothiazide, it has been found to lower blood pressure even further.

How Triamterene works in the body

Triamterene works on the kidneys to stop the body from absorbing too much sodium, which increases urine production. It blocks certain proteins called epithelial sodium channels from absorbing sodium ions from the peritubular medium and forces them out of the cells, leading to increased excretion of sodium, water, potassium, hydrogen, and chloride ions in the urine. Triamterene also increases the excretion of magnesium, unlike amiloride. Its action helps balance the levels of electrolytes in the body.

Triamterene Toxicity & Overdose Risk

The toxic dose of triamterene in rats is 400mg/kg and 285-380mg/kg in mice. There have been cases of reversible kidney failure from taking 50 pills containing 50mg triamterene and 25mg hydrochlorothiazide. Symptoms of overdose include nausea, vomiting, stomach pains, weakness, and low blood pressure due to changes in electrolyte levels. There is no specific antidote for triamterene overdose, so medical treatments such as vomiting and gastric lavage are used to remove the drug from the stomach. Dialysis may also be used to help reduce the effects of the overdose

Triamterene for High Blood Pressure

After taking this medication for two years, my blood pressure averaged 117/76. The side effects I experienced were morning dizziness, occasional dry mouth, and sometimes at bedtime. I decided to take the drug every other day instead of daily. After two months, there was no change. I tried eliminating the med entirely, and after three days my BP went up to 140/90. I resumed the drug 4 times per week. In two weeks I will test again and may have to resume a daily dose. Despite the minor side effects, I'll continue with a good diet and regular exercise.

Triamterene for High Blood Pressure

After a week of taking this medication, I have felt lightheadedness, fogginess, and heart flutters. These effects have been persistent for two days now, but my breathing has also become labored at times. I don't feel that my blood pressure has lowered as intended. I have a doctor's appointment tomorrow to discuss these issues further and currently am dieting in hopes of dropping weight so that I can get off the medication entirely.

Triamterene for High Blood Pressure

I would recommend keeping an eye on your sodium and potassium levels while taking this medication. I experienced some strange symptoms, including fainting, and it turns out that it was due to low sodium from taking triamterene for three years. Once I switched medications, my sodium levels were fine again.

Triamterene for Visible Water Retention

My doctor switched me to this medication from a diuretic combo that included this same drug because of my gout. I've been on it for almost a month now and I'm already retaining water again. All my joints hurt, especially my knees. Sometimes I get so lightheaded I feel like I'm going to pass out. This was supposed to be preventative against gout flares in the first place, but since being on it I've started having them again. Going to see about getting back on my old diuretic.

All Sexes
Halifax, Canada

The goal of this interventional study is to evaluate the implementation, usability, and clinical outcomes of a wearable medical-grade device in a virtual Cardiac Rehabilitation (CR) program, titled HEARTS in Sync. The question guiding this study is: Do patient clinical outcomes differ between those who use the CardioWatch 287-2 during the HEARTS in Sync program as compared to those who participate without using the CardioWatch 287-2? The comparison will happen between two non-randomized groups of patients who are enrolled in the HEARTS in Sync virtual CR program. The wearable device (CardioWatch 287-2), worn on patient's wrists, will provide clinicians with physiological information to better mirror the clinical oversight provided to an in-person CR program. Participants who choose to use the device will be asked to wear it daily. The clinical team will review weekly summary reports to help guide participant progress through the 13-week program. The primary objectives of this study are to: 1. Characterize participants (e.g., demographic health history, patient feedback) between those who choose to use the CardioWatch 287-2 device and those who do not. 2. Compare clinical outcomes between users and non-users of the device within the HEARTS in Sync program, by: 1. Tracking patient enrollment, attendance in virtual education sessions, and program completion rates, 2. Evaluating change in patient bloodwork outcomes, 3. Measuring change is physical ability, 4. Analyzing changes in eating behaviours, and 5. Examining quality of life using validated tools. 3. Asses the feasibility of the CardioWatch 287-2 for the HEARTS in Sync virtual CR program by: 1. Assessing device adherence 2. Reviewing patient feedback survey, and 3. Determining if clinician team were able to access and interpret data collected throughout the program The secondary objective of this study is to compare clinical outcomes of device users during the HEARTS in Sync program with patients who completed the on-site CR program. This research aims to better understand how a medical-grade device may improve virtual CR programming to extend clinical care to the community. As a result, this could lead to a more personalized care and better results for patients.

Meal Macronutrients for Blood Fat Levels

18 - 120
All Sexes
Bethesda, MD

Background: Abnormal fats in the blood can lead to many problems, including heart disease. Researchers want to learn more about how eating meals with different levels of nutrients affects fats in the blood. Specifically, they want to study people with too much body fat, too little body fat, and a kidney problem called nephrotic syndrome. Objective: To learn more about how different types of foods affect fat levels in the blood. Eligibility: People aged 18 years or older with a health condition that affects how their body handles fats. Healthy volunteers are also needed. Design: Participants will have 2 overnight stays in the clinic within 6 months. At each visit, after staying overnight, they will eat a breakfast casserole. At 1 visit, breakfast will be a high-fat, low carbohydrate meal. At the other, it will be a high-carbohydrate, low-fat meal. Participants will have a tube inserted into a vein in their arm. They will have blood drawn via the tube 12 times in 8 hours: 2 times before they eat the breakfast and 10 times after. Participants will have other tests during their stays: * A resting metabolic test captures the air they exhale and measures how much energy they use at rest. * A dual energy X-ray absorptiometry (DXA) scan measures how much fat and muscle they have. * A Fibroscan is a special type of ultrasound of the liver. * A body surface scan uses lasers to measure the total area of the body. * A bioelectric impedance (BIS) exam measures how fast small electric currents move through their body. Participants may opt to have a third visit. At this visit, the breakfast will be high in protein.

Dietary Interventions for Hypertension

18+
All Sexes
Birmingham, AL

Natriuretic peptides (NPs) are hormones produced by the heart and play an important role in maintaining cardiovascular health and have favorable metabolic benefits. Low NP levels are associated with an increased likelihood of the development of cardiometabolic diseases like diabetes and hypertension. NP levels are known to be highly heritable, with up to half of the differences in NP levels being explained by genetics. The investigators aim to describe the genetic architecture of NPs by examining the genetic variants associated with NPs, and generate and validate a polygenic score (PGS) for NPs. The investigators will use this NP PGS to examine the association of genetically determined NP levels with cardiometabolic and cardiovascular outcomes. The investigators will conduct a genotype-guided physiological clinical trial that aims to assess the genetic factors affecting NP levels and their impact on blood pressure and NP response to saline infusion, high-salt diet, and low-salt diet. These findings will help support personal medicine approaches to lower the increasing burden of hypertension in the United States.

Endovascular Treatment for Stroke

18+
All Sexes
Richmond, VA

Endovascular therapy (EVT) has proven to be more beneficial for patients with AIS caused by large vessel occlusions (LVO) than medical management alone. A recent meta-analysis of 5 RCTs showed that EVT significantly reduced disability at 90 days compared to medical management \[1\]. Despite its obvious benefits, patients may have neurological deterioration despite successful thrombectomy due to ischemia progression, intracranial hemorrhage, re-occlusion, or vasogenic edema. The incidence of early neurological deterioration (END) following EVT for acute stroke has been reported to be ranging from 14.1-35.2% with some studies defining END up to 7 days and some restricting the definition between 6-72 hours post thrombectomy. A small proportion of these patients, approximately 5.9-10.5%, experienced sICH following EVT. Whether END occurs due to ischemic or hemorrhagic it leads to worse outcomes.
