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

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.

Produce Prescription for High Blood Pressure

18+
All Sexes
Honokaa, HI

This multi-site randomized controlled trial uses a community-based approach to evaluate a Food as Medicine program for Native Hawaiian and Pacific Islander (NHPI) adults in Hawaii who have high blood pressure and difficulty affording healthy food. The study has two main goals: (1) to implement a produce prescription program and see if adding personal support from Community Health Workers (CHW) improves blood pressure among other health outcomes, and (2) to determine the program's cost-effectiveness. The study will take place across three Federally Qualified Health Centers in Hawaii. Produce prescription program participants at each site will receive $100 per month, either in the form of produce boxes or monthly vouchers to purchase fruits and vegetables, for 12 months (totaling $1200). In past studies, personal challenges (e.g., lack of transportation, lack of cooking skills) have made it difficult for participants to use the vouchers and/or the purchased produce. In other food as medicine interventions, participants have similarly faced various personal, social, and environmental barriers that limit the program's efficacy. To help participants navigate through these challenges, the investigators want to test adding 1-on-1 support from a CHW throughout the program. Other studies have found that health interventions delivered by CHWs have been effective in reducing blood pressure, blood glucose and weight, especially among vulnerable populations, such as NHPIs and those with food insecurity. The CHWs in this study will receive a training using a curriculum tailored specifically to their community and that is in alignment with the Pilinahā: The Four Connections Framework, which focuses on key connections that Indigenous people seek to attain health and can be employed to overcome health disparities. To test the effectiveness of the added CHW support, there will be two groups of participants: Group 1 (Intervention) will receive the monthly produce prescription ($100 vouchers or produce box) plus meet with a CHW every two months for support with program challenges. Group 2 (Control) will receive the same monthly produce prescription, but will not have meetings with a CHW. The investigators want to see if the added support from CHWs leads to better blood pressure results, among other health outcomes. Upon providing informed consent and enrolling into the program, produce prescription program participants will: * Attend 5 study visits over the one year program. These happen at the start, and then at 3, 6, 9, and 12 months. * Complete health checks at the first visit. This includes getting a home blood pressure monitor and learning about heart health and nutrition. Staff will measure height, weight, waist size, and blood pressure. * Answer surveys about their demographic background, health habits, diet, and culture. * Receive $100 in vouchers every month for 12 months to redeem for fruits and vegetables at a local retailer. * Group 1 will additionally meet with a CHW every two months for 1-on-1 support with any challenges related to the program. * Group 2 will receive monthly reminders to use their vouchers but no CHW meetings. After the program ends, researchers will analyze the financial value of the intervention. This involves calculating the total cost to run the program (including vouchers, CHW training and salaries, and administrative costs) and comparing it to potential savings in healthcare costs. By looking at improvements in blood pressure, researchers can estimate how many heart-related health problems were prevented and how much money was saved on medical care.

All Sexes
Fayetteville, AR

In this study, the investigators are conducting a Type 3 hybrid effectiveness-implementation trial to evaluate the implementation of the Community Health Workers (CHW)-delivered PILI Pasifika Program (PPP) across 3 regions, the U.S. Affiliated Pacific Islands (USAPI), the continental U.S., and Hawai'i, among 400 Native Hawaiian and Pacific Islander (NHPI) participants in two settings, (clinical and non-clinical) over a 3-year period. The PPP is a 3-month lifestyle intervention that includes a Social Determinants of Health (SDOH) component and was NHPI-adapted from the Diabetes Prevention Program's Lifestyle Program, renamed to the PILI Lifestyle Program (PLP), which demonstrated effectiveness in improving weight, blood pressure, physical activity, and diet among NHPIs. The PPP consists of 8 lifestyle lessons and 4 SDOH activities delivered over a 3-month period. The aims of this study are threefold: 1. To evaluate the implementation of the PPP across multiple community sites using a Type 3 hybrid effectiveness-implementation design guided by established frameworks such as RE-AIM and PRISM. 2. To examine participant-level outcomes associated with PPP implementation, including changes in cardiometabolic risk factors, health behaviors, and SDOH factors from baseline to 3 and 9-month follow-up. 3. To evaluate the cost and cost-effectiveness of implementing the PPP across community settings.

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.
