Renagel® is a phosphate binder indicated for the control of serum phosphorus in patients with chronic kidney disease on dialysis. (1)

DOSAGE AND ADMINISTRATION

Starting dose is one or two 800 mg or two to four 400 mg tablets three times per day with meals. (2)

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 Renagel 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)
Similar reactions at similar rates occurred in hemodialysis and peritoneal dialysis patients. (6.1)
Cases of fecal impaction and, less commonly, ileus, bowel obstruction, and bowel perforation have been reported. (6.2)

DRUG INTERACTIONS

When clinically significant drug interactions are expected, consider separation of the timing of administration and/or 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 has demonstrated interaction with ciprofloxacin, and mycophenolate mofetil, and therefore these drugs should be dosed separately from Renagel. (7)

1 INDICATIONS AND USAGE

RENAGEL®1 (sevelamer hydrochloride) is indicated for the control of serum phosphorus in patients with chronic kidney disease (CKD) on dialysis. The safety and efficacy of Renagel in CKD patients who are not on dialysis have not been studied.

Renagel is a Registered Trademark of Genzyme Corporation.

2 DOSAGE AND ADMINISTRATION

Patients Not Taking a Phosphate Binder. The recommended starting dose of Renagel is 800 to 1600 mg, which can be administered as one or two 800 mg Renagel® Tablets or two to four 400 mg Renagel® Tablets, with meals based on serum phosphorus level. Table 1 provides recommended starting doses of Renagel for patients not taking a phosphate binder.

Table 1. Starting Dose for Dialysis Patients Not Taking a Phosphate Binder
Serum Phosphorus	Renagel® 800 mg	Renagel® 400 mg
> 5.5 and < 7.5 mg/dL	1 tablet three times daily with meals	2 tablets three times daily with meals
≥ 7.5 and < 9.0 mg/dL	2 tablets three times daily with meals	3 tablets three times daily with meals
≥ 9.0 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 Renagel and calcium acetate. Table 2 gives recommended starting doses of Renagel based on a patient's current calcium acetate dose.
