🩺 Clinical
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. It binds phosphorus that you get from foods in your diet and prevents it from being absorbed into your blood stream.

( 1 )
⏱️ Dosage and Administration ▾
2 DOSAGE & ADMINISTRATION Patients Not Taking a Phosphate Binder. The recommended starting dose of sevelamer hydrochloride tablets is 800 mg to 1600 mg, which can be administered as one or two 800 mg sevelamer hydrochloride tablets or two to four 400 mg sevelamer hydrochloride tablets, with meals based on serum phosphorus level. Table 1 provides recommended starting doses of sevelamer hydrochloride tablets for patients not taking a phosphate binder.
Table 1: Starting Dose for Dialysis Patients Not Taking a Phosphate Binder Serum Phosphorus Sevelamer Hydrochloride Tablets 800 mg Sevelamer Hydrochloride Tablets 400 mg Greater than 5.5 and less than 7.5 mg/dL 1 tablet three times daily with meals 2 tablets three times daily with meals Greater than or equal to 7.5 and less than 9 mg/dL 2 tablets three times daily with meals 3 tablets three times daily with meals Greater than or equal to 9 mg/dL 2 tablets three times daily with meals 4 tablets three times daily with meals Patients Switching from Calcium Acetate.
In a study in 84 CKD patients on hemodialysis, a similar reduction in serum phosphorus was seen with equivalent doses (approximately mg for mg) of sevelamer hydrochloride tablets and calcium acetate. Table 2 gives recommended starting doses of sevelamer hydrochloride tablets based on a patient’s current calcium acetate dose. Table 2: Starting Dose for Dialysis Patients Switching From Calcium Acetate to Sevelamer Hydrochloride Tablets Calcium Acetate 667 mg (Tablets per meal) Sevelamer Hydrochloride Tablets 800 mg (Tablets per meal) Sevelamer Hydrochloride Tablets 400 mg (Tablets per meal) 1 tablet 1 tablet 2 tablets 2 tablets 2 tablets 3 tablets 3 tablets 3 tablets 5 tablets Dose Titration for All Patients Taking Sevelamer Hydrochloride Tablets.
Adjust dosage based on the serum phosphorus concentration with a goal of lowering serum phosphorus to 5.5 mg/dL or less. Increase or decrease by one tablet per meal at two-week intervals as necessary. Table 3 gives a dose titration guideline.
The average dose in a Phase 3 trial designed to lower serum phosphorus to 5 mg/dL or less was approximately three sevelamer hydrochloride 800 mg tablets per meal. The maximum average daily sevelamer hydrochloride tablets dose studied was 13 g. Table 3: Dose Titration Guideline Serum Phosphorus Sevelamer Hydrochloride Tablets Dose Greater than 5.5 mg/dL Increase 1 tablet per meal at 2-week intervals 3.5 to 5.5 mg/dL Maintain current dose Less than 3.5 mg/dL Decrease 1 tablet per meal • Starting dose is one or two 800 mg or two to four 400 mg tablets three times per day with meals.

⚠️ Warnings and Cautions ▾
5 WARNINGS AND PRECAUTIONS • Serious cases of dysphagia, bowel obstruction, bleeding gastrointestinal ulcers, colitis, ulceration, necrosis, and perforation have been associated with sevelamer use, some requiring hospitalization and surgery. ( 5.1 )
5.1Gastrointestinal Adverse Events Patients with dysphagia, swallowing disorders, severe gastrointestinal (GI) motility disorders, including severe constipation, or major GI tract surgery were not included in the sevelamer hydrochloride clinical studies. Dysphagia and esophageal tablet retention have been reported in association with use of sevelamer tablets, some requiring hospitalization and intervention. Consider using sevelamer suspension in patients with a history of swallowing disorders.
Cases of bowel obstruction, bleeding gastrointestinal ulcers, colitis, ulceration, necrosis, and perforation have also been reported with sevelamer use [see Adverse Reactions ( 6.2 )] . Inflammatory disorders may resolve upon sevelamer hydrochloride discontinuation. Treatment with sevelamer hydrochloride should be re-evaluated in patients who develop severe gastrointestinal symptoms.
5.2Monitor Serum Chemistries Bicarbonate and chloride levels should be monitored.
5.3Monitor for Reduced Vitamins D, E, K (clotting factors) and Folic Acid Levels In preclinical studies in rats and dogs, sevelamer hydrochloride reduced vitamins D, E, and K (coagulation parameters) and folic acid levels at doses of 6 to 10 times the recommended human dose. In short-term clinical trials, there was no evidence of reduction in serum levels of vitamins. However, in a one-year clinical trial, 25-hydroxyvitamin D (normal range 10 to 55 ng/mL) fell from 39 ± 22 ng/mL to 34 ± 22 ng/mL (p less than 0.01) with sevelamer hydrochloride treatment.
Most (approximately 75%) patients in sevelamer hydrochloride clinical trials received vitamin supplements, which is typical of patients on dialysis.
🤒 Adverse Reactions ▾
6 ADVERSE REACTIONS • The most common reasons for discontinuing treatment were gastrointestinal adverse reactions. ( 6.1 ) • In a parallel design study of 12 weeks duration, treatment-emergent adverse reactions to sevelamer hydrochloride tablets in peritoneal dialysis patients included dyspepsia (12%), peritonitis (8%), diarrhea (5%), nausea (5%), constipation (4%), pruritus (4%), abdominal distension (3%), vomiting (3%), fatigue (3%), anorexia (3%), and arthralgia (3%). ( 6.1 ) • Cases of fecal impaction and, less commonly, ileus, bowel obstruction, and bowel perforation have been reported.
( 6.2 ) To report SUSPECTED ADVERSE REACTIONS, contact Macleods Pharma USA, Inc. at 1-888-943-3210 or 1-855-926-3384 or FDA at 1-800-FDA-1088 or www.fda.gov/medwatch.
6.1Clinical Trials Experience Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice. In a parallel design study of sevelamer hydrochloride with treatment duration of 52 weeks, adverse reactions reported for sevelamer hydrochloride (n=99) were similar to those reported for the active-control group (n=101). Overall adverse reactions among those treated with sevelamer hydrochloride occurring in greater than 5% of patients included: vomiting (22%), nausea (20%), diarrhea (19%), dyspepsia (16%), abdominal pain (9%), flatulence (8%), and constipation (8%).
A total of 27 patients treated with sevelamer and 10 patients treated with comparator withdrew from the study due to adverse reactions. Based on studies of 8 to 52 weeks, the most common reason for withdrawal from sevelamer hydrochloride was gastrointestinal adverse reactions (3% to 16%). In 143 peritoneal dialysis patients studied for 12 weeks, most adverse reactions were similar to adverse reactions observed in hemodialysis patients.
The most frequently occurring treatment-emergent serious adverse reaction was peritonitis (8 reactions in 8 patients [8%] in the sevelamer group and 2 reactions in 2 patients [4%] on active control). Thirteen patients (14%) in the sevelamer group and 9 patients (20%) in the active-control group discontinued, mostly for gastrointestinal adverse reactions. Patients on peritoneal dialysis should be closely monitored to ensure the reliable use of appropriate aseptic technique with the prompt recognition and management of any signs and symptoms associated with peritonitis.
6.2Postmarketing Experience The following adverse reactions have been identified during postapproval use of sevelamer hydrochloride tablets: hypersensitivity, pruritus, rash, abdominal pain, bleeding gastrointestinal ulcers, colitis, ulceration, necrosis, fecal impaction and uncommon cases of ileus, intestinal obstruction, and intestinal perforation. Appropriate medical management should be given to patients who develop constipation or have worsening of existing constipation to avoid severe complications. Because these reactions are reported voluntarily from a population of uncertain size, it is not always possible to estimate their frequency or to establish a causal relationship to drug exposure.
🔄 Drug Interactions ▾
7 DRUG INTERACTIONS There are no empirical data on avoiding drug interactions between sevelamer hydrochloride and most concomitant oral drugs. For oral medication where a reduction in the bioavailability of that medication would have a clinically significant effect on its safety or efficacy (e.g., cyclosporine, tacrolimus, levothyroxine), consider separation of the timing of the administration of the two drugs [see Clinical Pharmacology ( 12.3 )] . The duration of separation depends upon the absorption characteristics of the medication concomitantly administered, such as the time to reach peak systemic levels and whether the drug is an immediate-release or an extended-release product.
Where possible monitor clinical responses or blood levels of concomitant drugs that have a narrow therapeutic range. Table 4: Sevelamer Drug Interactions Oral drugs for which sevelamer did not alter the pharmacokinetics when administered concomitantly Digoxin Enalapril Iron Metoprolol Warfarin Oral drugs that have demonstrated interaction with sevelamer and are to be dosed separately from sevelamer hydrochloride Dosing Recommendations Ciprofloxacin Mycophenolate mofetil Take at least 2 hours before or 6 hours after sevelamer Take at least 2 hours before sevelamer • When clinically significant drug interactions are expected, separate the timing of administration and monitor clinical responses or blood levels of the concomitant medication.
( 7 ) • Sevelamer did not alter the pharmacokinetics of digoxin, enalapril, iron, metoprolol, and warfarin. ( 7 ) • Sevelamer binds ciprofloxacin and mycophenolate mofetil; dose these drugs separately from sevelamer hydrochloride. ( 7 )
👥 Use in Specific Populations ▾
8 USE IN SPECIFIC POPULATIONS
8.1Pregnancy Risk Summary Sevelamer hydrochloride is not absorbed systemically following oral administration and maternal use is not expected to result in fetal exposure to the drug. Clinical Considerations Sevelamer hydrochloride may decrease serum levels of fat soluble vitamins and folic acid in pregnant women [see Clinical Pharmacology ( 12.2 )]. Consider supplementing with these vitamins.
Data Animal data In pregnant rats given dietary doses of 0.5, 1.5, or 4.5 g/kg/day of sevelamer hydrochloride during organogenesis, reduced or irregular ossification of fetal bones, probably due to a reduced absorption of fat-soluble vitamin D, occurred at 7-21 times the maximum human equivalent dose of 13 g based on 60 kg body weight. In pregnant rabbits given oral doses of 100, 500, or 1000 mg/kg/day of sevelamer hydrochloride by gavage during organogenesis, an increase of early resorptions occurred in the high-dose group (human equivalent dose approximately 5 times the maximum clinical trial dose based on 60 kg body weight).
8.2Lactation Risk Summary Sevelamer hydrochloride is not absorbed systemically by the mother following oral administration and breastfeeding is not expected to result in exposure of the child to sevelamer hydrochloride. Clinical Considerations Sevelamer hydrochloride may decrease serum levels of fat soluble vitamins and folic acid in lactating women [see Clinical Pharmacology ( 12.2 )]. Consider supplementing with these vitamins.
8.4Pediatric Use The safety and efficacy of sevelamer hydrochloride has not been established in pediatric patients.
8.5Geriatric Use Clinical studies of sevelamer hydrochloride did not include sufficient numbers of subjects aged 65 and over to determine whether they respond differently from younger subjects. Other reported clinical experience has not identified differences in responses between the elderly and younger patients. In general, dose selection for an elderly patient should be cautious, usually starting at the low end of the dosing range.

🆘 Overdosage ▾
10 OVERDOSAGE Sevelamer hydrochloride has been given to normal healthy volunteers in doses of up to 14 g per day for eight days with no adverse effects. Sevelamer hydrochloride has been given in average doses up to 13 g per day to hemodialysis patients. There are no reports of overdosage with sevelamer hydrochloride in patients. Since sevelamer hydrochloride is not absorbed, the risk of systemic toxicity is low.
🧬 Clinical Pharmacology ▾
12 CLINICAL PHARMACOLOGY
12.1Mechanism of Action Sevelamer hydrochloride tablet contains sevelamer hydrochloride, a non-absorbed binding crosslinked polymer. 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.
By binding phosphate in the dietary tract and decreasing absorption, sevelamer hydrochloride lowers the phosphate concentration in the serum.
12.2Pharmacodynamics In addition to effects on serum phosphate levels, sevelamer hydrochloride has been shown to bind bile acids in vitro and in vivo in experimental animal models. Bile acid binding by ion exchange resins is a well-established method of lowering blood cholesterol. Because sevelamer binds bile acids, it may interfere with normal fat absorption and thus may reduce absorption of fat-soluble vitamins such as A, D, and K.
In clinical trials of sevelamer hydrochloride, both the mean total and LDL cholesterol declined by 15% to 31%. This effect is observed after 2 weeks. Triglycerides, HDL cholesterol, and albumin did not change.
12.3Pharmacokinetics A mass balance study using 14 C-sevelamer hydrochloride in 16 healthy male and female volunteers showed that sevelamer hydrochloride is not systemically absorbed. No absorption studies have been performed in patients with renal disease. Drug Interactions In vivo Sevelamer carbonate has been studied in human drug-drug interaction studies (9.6 g once daily with a meal) with warfarin and digoxin.
Sevelamer hydrochloride, which contains the same active moiety as sevelamer carbonate, has been studied in human drug-drug interaction studies (2.4 to 2.8 g single dose or three times daily with meals or two times daily without meals) with ciprofloxacin, digoxin, enalapril, iron, metoprolol, mycophenolate mofetil and warfarin. Coadministered single dose of 2.8 g of sevelamer hydrochloride in fasted state decreased the bioavailability of ciprofloxacin by approximately 50% in healthy subjects. Concomitant administration of sevelamer and mycophenolate mofetil in adult and pediatric patients decreased the mean MPA C max and AUC 0 to 12h by 36% and 26%, respectively.
Sevelamer carbonate or sevelamer hydrochloride did not alter the pharmacokinetics of a single dose of enalapril, digoxin, iron, metoprolol and warfarin when coadministered. During postmarketing experience, cases of increased thyroid stimulating hormone (TSH) levels have been reported in patients coadministered sevelamer hydrochloride and levothyroxine. Reduction in concentrations of cyclosporine and tacrolimus leading to dose increases has also been reported in transplant patients when coadministered with sevelamer hydrochloride without any clinical consequences (e.g., graft rejection).
The possibility of an interaction cannot be excluded with these drugs.
