Description
11 DESCRIPTION The active ingredient in sevelamer carbonate tablet is sevelamer carbonate, a polymeric amine that binds phosphate and is meant for oral administration. It was developed as a pharmaceutical alternative to sevelamer hydrochloride. Sevelamer carbonate is an anion exchange resin, with the same polymeric structure as sevelamer hydrochloride, in which carbonate replaces chloride as the counterion. While the counterions differ for the two salts, the polymer itself, the active moiety involved in phosphate binding, is the same. 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. Figure 1. Chemical Structure of Sevelamer Carbonate a, b = number of primary amine groups a + b = 9 c = number of cross-linking groups c = 1 m = large number to indicate extended polymer network Sevelamer carbonate Tablets: Each film-coated tablet of sevelamer carbonate contains 800 mg of sevelamer carbonate on an anhydrous basis. The inactive ingredients are ammonium hydroxide, colloidal silicon dioxide, crospovidone, hydroxypropyl cellulose, lecithin, mannitol, polyvinyl alcohol, propylene glycol, shellac, talc, xanthan gum and zinc stearate. The tablet imprint contains iron oxide black ink.

Indications & Usage
1 INDICATIONS AND USAGE Sevelamer carbonate tablets are indicated for the control of serum phosphorus in adults and children 6 years of age and older with chronic kidney disease (CKD) on dialysis. Sevelamer carbonate tablet is a phosphate binder indicated for the control of serum phosphorus in adults and children 6 years of age and older with chronic kidney disease on dialysis. (1 )
Dosage and Administration
2 DOSAGE AND ADMINISTRATION Starting dose of sevelamer carbonate tablet is 0.8 or 1.6 grams administered orally three times per day with meals based on serum phosphorus levels for adult patients and based on body surface area (BSA) category for pediatric patients ( 2.1 ) Titrate by 0.8 grams per meal in two week intervals for adult patients as needed to obtain serum phosphorus target. ( 2.1 ) Titrate based on BSA category for pediatric patients in two week intervals for 6 weeks and then every 4 weeks as needed to obtain serum phosphorus target. ( 2.1 ) 2.1 General Dosing Information Starting Dose for Adult Patients Not Taking a Phosphate Binder . The recommended starting dose of sevelamer carbonate tablets are 0.8 to 1.6 grams taken orally with meals based on serum phosphorus level. Table 1 provides recommended starting doses of sevelamer carbonate tablets for adult patients not taking a phosphate binder. Table 1. Starting Dose for Adult Dialysis Patients Not Taking a Phosphate Binder Serum Phosphorus Sevelamer Carbonate > 5.5 and < 7.5 mg/dL 0.8 grams three times daily with meals ≥ 7.5 mg/dL 1.6 grams three times daily with meals Dose Titration for Adult Patients Taking Sevelamer Carbonate Tablets . Titrate the sevelamer carbonate tablets dose by 0.8 grams three times per day with meals at two-week intervals as necessary to achieve target serum phosphorus levels. Based on clinical studies, the average prescribed adult daily dose of sevelamer carbonate is approximately 7.2 grams per day. The highest daily adult dose of sevelamer carbonate studied was 14 grams in CKD patients on dialysis. Starting Dose for Pediatric Patients Not Taking a Phosphate Binder. The recommended starting dose for pediatric patients 6 years of age and older is 0.8 to 1.6 grams taken three times per day with meals based on the patient’s body surface area (BSA) category; see Table 2. Table 2: Recommended Starting Dosage and Titration Increment Based on Pediatric Patient’s Body Surface Area (m 2 ) BSA (m 2 ) Starting Dose Per Meal/Snack Titration Increases/ Decreases Per Dose ≥0.75 to <1.2 0.8 grams Titrate by 0.4 grams ≥1.2 1.6 grams Titrate by 0.8 grams Dose Titration for Pediatric Patients Taking Sevelamer Carbonate Tablets . Titrate the sevelamer caronate dose as needed to achieve target levels at two-week intervals based on BSA category, as shown in Table 2. Switching from Sevelamer Hydrochloride Tablets . For adult patients switching from sevelamer hydrochloride tablets to sevelamer carbonate tablets or powder, use the same dose in grams. Switching between Sevelamer Carbonate Tablets and Powder . Use the same dose in grams. Switching from Calcium Acetate . Table 3 gives recommended starting doses of sevelamer carbonate tablets based on a patient’s current calcium acetate dose. Table 3.
