What is sevelamer carbonate made of?
The sevelamer moiety consists of a carbon backbone with multiple amine groups, each separated from the backbone by a single carbon atom. In the intestine, Sevelamer carbonate become protonated and subsequently bind to dietary phosphorus molecules via ionic and hydrogen interactions.
What is the mechanism of action for sevelamer?
MECHANISM OF ACTION Sevelamer binds dietary phosphate within the gastrointestinal tract. It contains multiple amines separated by one carbon from the polymer backbone. These amines exist in a protonated form in the intestine and interact with phosphate molecules through ionic and hydrogen bonding.
What is the difference between sevelamer carbonate and HCL?
The main difference between sevelamer carbonate and sevelamer hydrochloride is that the chloride in the sevelamer resin was replaced by bicarbonate. That’s the only difference. With sevelamer hydrochloride some patients develop metabolic acidosis because in the intestine chloride is exchanged for bicarbonate.
What is the function of sevelamer carbonate?
Sevelamer is used to control high blood levels of phosphorus in people with chronic kidney disease who are on dialysis (medical treatment to clean the blood when the kidneys are not working properly). Sevelamer is in a class of medications called phosphate binders.
Is sevelamer same as calcium carbonate?
Results: Sevelamer carbonate significantly improved lipid profile compared with calcium carbonate. Amongst the EF and pro-inflammatory biomarkers, sevelamer carbonate decreased serum endothelin-1, plasminogen activator inhibitor-1, C-reactive protein and interleukin-6.
What is another name for sevelamer carbonate?
Renvela® (sevelamer carbonate) is used to control phosphorus levels in adults and children 6 years of age and older with chronic kidney disease (CKD) on dialysis.
How do phosphate binders work?
To reduce the amount of phosphate you absorb from your food you may have been prescribed a medicine called a phosphate binder. Phosphate binders work by binding (attaching) to some of the phosphate in food. This will reduce the amount of phosphate being absorbed into your blood stream.
Does sevelamer carbonate contain calcium?
Sevelamer carbonate does not contain any calcium. Serum calcium levels should therefore be monitored at regular intervals and elemental calcium should be given as a supplement if required. Patients with CKD are predisposed to developing metabolic acidosis.
Does sevelamer bind calcium?
Sevelamer hydrochloride is a non-calcium, non-metal-based phosphate binder that provides effective control of serum phosphorus levels in patients on HD but with fewer episodes of hypercalcaemia and less suppression of parathyroid hormone (PTH) than calcium acetate or calcium carbonate [ 7 ].
Who manufactures sevelamer carbonate?
Sevelamer carbonate—the authorized generic identical to Renvela. Winthrop US is a Sanofi company dedicated to delivering brand-equal generics of Sanofi products, including Renvela.
What is the structure of sevelamer carbonate?
Sevelamer carbonate is known chemically as poly (allylamine- co -N,N-diallyl-1,3-diamino-2-hydroxypropane) carbonate salt. Sevelamer carbonate is hygroscopic, but insoluble in water. The structure is represented in Figure 1.
How do you titrate sevelamer carbonate tablets?
Dose Titration for Adult Patients Taking Sevelamer Carbonate Tablets. Titrate the Sevelamer Carbonate Tablets dose by 0.8 g three times per day with meals at two-week intervals as necessary to achieve target serum phosphorus levels.
Does sevelamer hydrochloride raise bicarbonate levels?
Sevelamer carbonate and sevelamer hydrochloride were equivalent in controlling serum phosphorus, while serum bicarbonate levels increased with sevelamer carbonate [172,173]. Many clinical studies have shown that sevelamer is effective in lowering serum phosphate level and is generally well tolerated.
Does sevelamer carbonate lower serum phosphorus levels?
In clinical trials, sevelamer carbonate has been shown to lower serum phosphorus levels and calcium-phosphorus product to a similar extent as sevelamer hydrochloride.
