What is Fosrenol

Lanthanum carbonate

The Generic name of this drug

Treatment Summary

Lanthanum carbonate, also known as Fosrenol, is a medication used to lower high phosphate levels in people with chronic kidney disease. It is a large pill that should be chewed and taken with meals to help bind to the phosphate in food and stop it from being absorbed by the intestine. Sometimes people forget to chew the pill and have experienced severe choking as a result.

Effectiveness

How Fosrenol Affects Patients

Laboratory tests have shown that lanthanum can effectively bind phosphate at a range of acidity levels found in the human body (pH 3-7). When tested in a simulated stomach environment, lanthanum was able to bind up to 97% of the available phosphate when it was present in double the amount of phosphate. Bile acids do not affect the phosphate binding ability of lanthanum. To work properly, lanthanum must be taken with or right after meals.

How Fosrenol works in the body

Lanthanum carbonate helps to reduce the amount of phosphate absorbed by the body. It does this by forming a complex with the phosphate that cannot be absorbed by the body. This complex then passes through the digestive system, preventing it from entering the bloodstream. As a result, the amount of both phosphate and calcium phosphate in the body is reduced.

Fosrenol for Renal Osteodystrophy with Hyperphosphatemia

I find that grinding the tablets into a powder makes them much easier to take and improves the taste. I actually enjoy the sweetness of the powder.

Fosrenol for High Amount of Phosphate in the Blood

As a home hemodialysis patient, my phosphorus levels were through the roof. 11.0 to be exact. But after my nutritionist suggested I try Fosrenol (2 500mg chewable tablets with meals and snacks), it lowered my phosphorus all the way down to 3.5; which is well within the normal range of 3.5-5.5. Not only that, but this product tastes like tums! And I have experienced zero stomach problems or nausea from taking it regularly.

Fosrenol for High Amount of Phosphate in the Blood

I'm on dialysis for end stage renal failure, and this product has been great for keeping my phosphorus levels in check. I chew one 1000mg tablet after every meal and snack, and it's really helped me out.

Fosrenol for High Amount of Phosphate in the Blood

I've had a great experience with this medication. It's easy to chew and I stay in range on my report card. Some of the other comments mention having trouble with upset stomach and nausea, but that improved for me within two months.

Fosrenol for High Amount of Phosphate in the Blood

I've been taking Fosrenol for a few months now and have experienced worsening nausea and vomiting. I'm wondering if anyone else has had similar issues?

Patient Q&A Section about fosrenol

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

What type of medication is Fosrenol?

"FOSRENOL works by binding phosphate in the gut so that it isn't absorbed into the body, reducing serum phosphate levels."

Answered by AI

When should I take Fosrenol?

"Fosrenol should be taken with food to avoid nausea and vomiting. The tablets must be chewed completely and not swallowed whole. To aid with chewing, the tablets may be crushed."

Answered by AI

Is there a generic for Fosrenol?

"Lanthanum, the generic version of the drug Fosrenol, may be much cheaper than the brand version of the drug."

Answered by AI

What is Fosrenol used for?

"Fosrenol prevents the body from absorbing phosphate by bind to it in the gastrointestinal tract, which then allows it to be removed from the body through the feces. This medication is used to treat patients with end stage renal disease who have high phosphate levels in their blood, which can lead to problems with calcium absorption and other serious medical problems."

GGTA1 KO Thymokidney for Kidney Failure

40 - 70
All Sexes
New York, NY

The purpose of this study is to evaluate the safety and efficacy of the GGTA1 KO Thymokidney in patients with end-stage renal disease (ESRD) who are either not eligible for conventional allogeneic kidney transplantation (Group 1) or are on an Organ Procurement and Transplantation Network (OPTN) kidney transplant waitlist, but are more likely to die or go untransplanted within 5 years than receive a kidney transplant (Group 2). The study consists of xenotransplantation followed by a 24-week Post-transplant Follow-up Period (Part A) to evaluate the efficacy and safety objectives followed by a Long-term Follow-up Period (Part B) to evaluate participant survival, GGTA1 KO Thymokidney survival, and screening for zoonotic infections. Part B will continue for the lifetime of the participant or for 52 weeks following nephrectomy, if required.

AP301 for High Phosphate Levels

Any Age
All Sexes
Lone Tree, CO

The goal of this clinical trial is to learn if AP301 could work in the patients receiving maintenance dialysis with elevated blood phosphate. The main questions it aims to answer are: * Does AP301 lower blood phosphate levels? * Does AP301 works on serum calcium level, calcium times phosphate level, and intact parathyroid hormone level? * What discomfort or medical problem do the patients have when taking AP301? * Does AP301 improve quality of life in Chinese patients? The researchers will compare AP301 to an ineffective comparator (a look-alike substance that contains low dose AP301) to see if AP301 works to treat elevated blood phosphate. In the study, the patients will experience the following stages in a chronicle order: * Stop all using blood phosphate-lowering drugs, * Take AP301 or the comparator three times a day for 8 weeks, * Take AP301 three times a day for 24 weeks, and * Take AP301 or the comparator three times a day for 3 weeks. In the first 32 weeks, the dose of AP301 will be adjusted upwards or downwards based on the patient's blood phosphate level and the study doctor's judgment. If the participant has a blood phosphate level above or below a certain level, they may receive additional treatment to lower the blood phosphate level.

Bupropion for Fatigue in Kidney Failure

25 - 74
All Sexes
San Antonio, TX

Fatigue is the most common symptom reported by end-stage kidney disease patients on maintenance hemodialysis. Unfortunately, there currently is no medical management for this overwhelming feeling of tiredness. As a result, patients continue to suffer with poor quality of life and impaired daily activities. The purpose of this pilot trial is to find out if bupropion (a medicine commonly prescribed for stopping smoking, seasonal mood disorder, and depression) may help lessen fatigue in hemodialysis patients. In this study, hemodialysis participants will receive bupropion tablet orally three times a week during routine dialysis procedure for consecutive 8 weeks. Study participants will complete a battery of questionnaires to self-report fatigue, cognition, and quality of life. The study team will collect biological specimens. All these procedures will be performed at the dialysis clinic during routine dialysis procedure.
