What is Felodipine

Felodipine

The Generic name of this drug

Treatment Summary

Felodipine is a type of medication used to treat high blood pressure. It works by blocking calcium influx into the cells of the smooth muscle in the walls of the blood vessels, which helps relax the vessel and lower blood pressure. Felodipine is unique in that it binds to various calcium-binding proteins, competes with mineralcorticoid receptors, and blocks calcium influx through voltage-gated T-type calcium channels. This makes it the most potent calcium channel blocker currently available.

How Felodipine Affects Patients

Felodipine is a type of calcium channel blocker, which are drugs used to reduce blood pressure. It works by blocking the activity of certain types of calcium channels, and may also interfere with other proteins involved in muscle contraction, cell excitability and hormone regulation. Though it binds to many different molecules, it is believed that its main effects come from blocking the voltage-gated L-type calcium channels, which are more abundant in artery cells than in heart cells. This makes it more effective at reducing blood pressure in the arteries than in the heart.

How Felodipine works in the body

Felodipine works to reduce blood pressure by decreasing the amount of calcium that enters cells in your arteries. Normally, when calcium binds to a protein called calmodulin, it triggers a reaction that causes your arteries to contract. Felodipine prevents this reaction from happening, so your arteries stay relaxed and your blood pressure goes down. This makes felodipine an effective treatment for mild to moderate high blood pressure.

Felodipine for High Blood Pressure

I started having problems when I increased my dosage to 2.5 twice a day like the doctor recommended. I felt tired, foggy-eyed, and off balance all the time. Yesterday I stopped taking the drug altogether to see if that would help, and so far I'm feeling better.

Felodipine for High Blood Pressure

Initially, this worked well to reduce my high blood pressure. However, after some time my doctor prescribed calcium with vitamin D, and that caused me a lot of pain in my chest. I now have to avoid calcium supplements and soy entirely.

Felodipine for High Blood Pressure

Since starting felodopine 2 months ago, I have developed really bad pains at the back of both legs. My GP checked me for blood clots and said I was all clear. I was told that if it was the felodopine, I would have swollen legs and feet, but I don't. This has made my life miserable as I can't do any of the things I enjoy anymore.

Food is Medicine for High Blood Pressure and Obesity

Any Age
All Sexes
Chicago, IL

The goal of this clinical trial is to treat both hypertension and obesity in adults using a food is medicine framework. Participants will be randomized 1:1 to FIM+DASH or usual-care control. The 24-week trial includes a 12-week FIM+DASH intervention followed by a 12-week maintenance period and leverages existing partnerships with community-based organizations for home food delivery and culinary skill-skill building. The main questions it aims to answer are: (1) What is the effect of FIM+DASH vs. usual care control on blood pressure? (2) What is the effect of FIM+DASH vs. usual care control on DASH diet adherence (diet quality), body weight, and waist circumference? (3) How to identify factors associated with the sustainability and scalability of FIM+DASH in real-world settings?

Cuffless PPG Monitor for High Blood Pressure

All Sexes
Miami, FL

This study aims to validate the accuracy and reliability of blood pressure (BP) estimates obtained over 24 hours using a PPG-based chest-patch device compared to the gold standard ambulatory blood pressure monitoring (ABPM) method using an upper arm cuff-based oscillometric BP device, in both hypertensive and normotensive individuals referred by their provider to undergo a 24-hours ABPM for clinical indication. The Awake/Asleep test, which is the primary test recommended for automated wearable cuffless BP devices that are cuff-calibrated (based on the 2023 European Society of Hypertension (ESH) recommendations for the validation of cuffless blood pressure measuring devices), will be conducted in this study. The secondary aim of the study is to assess the feasibility and convenience of the PPG-based device.

This project is part of the ACHIEVE GREATER (Addressing Cardiometabolic Health In Populations Through Early PreVEntion in the GREAT LakEs Region) Center (IRB# 100221MP2A), the purpose of which is to improve cardiometabolic health in two uniquely comparable cities: Detroit, Michigan, and Cleveland, Ohio. The ACHIEVE GREATER Center involves separate but related projects that aim to improve cardiometabolic health outcomes through better risk factor control for three chronic conditions that are of tremendous public health importance, (hypertension (HTN), heart failure, and coronary heart disease), all of which contribute significantly to premature death in Detroit and Cleveland. The present study is the prospective observational cohort component of ACHIEVE P1- EPI (Project 1) of the ACHIEVE GREATER Center and serves to characterize the population of patients with blood pressure (BP) levels above normal attending The Wayne Health Mobile Health Unit (MHU) events to better understand key factors (e.g., social determinants of health) that convey information about baseline BP levels and related clinical outcomes (e.g., follow-up clinic visits, BP control, and cardiovascular events).

Flagstaff, AZ

This project aims to address healthcare disparities among Navaho people diagnosed with hypertension or prehypertension through three main objectives. Firstly, it identifies and shares insights on healthcare access disparities affecting Navaho individuals experiencing nonadherence to hypertension treatment. Secondly, the proposal develops a telehealth solution based on factors identified as knowledge gaps caused by healthcare access disparities in hypertension management; we will use the factors to design a series of engaging minigames that can be incorporated into the larger CardioCare Quest. These minigames will be co-designed with end users and clinicians. Finally, the proposal conducts comprehensive qualitative and quantitative assessments of user experiences, perceptions, and challenges with CardioCare Quest.

Though the Mississippi Delta has a rich agricultural history and some of the nation's most fertile soil, residents have experienced the legacy of slavery and economic exploitation through food insecurity and poverty for generations. This project focuses on Bolivar, Washington, and Sunflower, contiguous counties in the Delta that are designated as health disparity populations. Over 65% of the 100,000 residents are Black/African American and \~30% live at or below the poverty level. Obesity rates are high and the rate of diabetes is almost double the national average. Tufts University received a grant from the National Institute of Minority Health and Health Disparities to develop, test, and evaluate a Food is Medicine program in Mississippi. The Delta Growing a Resilient, Enriching, Equitable, Nourishing food System (GREENS) Food is Medicine (FIM) Project, is a collaborative project in Bolivar, Washington, and Sunflower counties in Mississippi. The intervention involves regularly distributed fruit and vegetable produce boxes as well as nutrition education materials to the intervention group. The control group will receive produce boxes later, after they complete study activities. The project's primary goal is to improve health outcomes by creating a FIM intervention. The Delta GREENS FIM Project aims to become a model for promoting nutrition security and management of chronic conditions in varied communities nationwide.
