- Lanthanum Carbonate (Fosrenol): A chewable tablet that binds to phosphorus in the digestive tract.
- Ferric Citrate (Auryxia): An iron-based binder that can also help improve iron levels in CKD patients.
- Sucroferric Oxyhydroxide (Velphoro): A chewable tablet that provides effective phosphorus control with a low pill burden.

How Phosphate Binders Work

Phosphate binders work by binding to phosphorus in the gastrointestinal tract, forming an insoluble compound that is excreted in the feces. This prevents the phosphorus from being absorbed into the bloodstream, helping to maintain normal phosphorus levels.

Mechanism of Action:
1. Phosphate binders are taken with meals.
2. The binder binds to phosphorus in the stomach and intestines.
3. The phosphorus-binder complex is not absorbed by the body.
4. The complex is excreted in the feces.

Importance Of Taking Phosphate Binders With Meals

It’s crucial to take phosphate binders with meals to maximize their effectiveness. Taking them on an empty stomach will not effectively bind to the phosphorus from the food you eat.

Timing: Take phosphate binders at the beginning of your meal or within a few minutes of eating.
Dosage: Follow your doctor’s instructions carefully regarding the dosage and frequency of phosphate binder use.
Consistency: Be consistent with your medication schedule to maintain stable phosphorus levels.

Side Effects Of Phosphate Binders

Like all medications, phosphate binders can have side effects. Common side effects include:

Calcium-Based Binders:
