Sevelamerum Uses, Dosage, Side Effects, Food Interaction and all others data.

Sevelamerum Hydrochloride is a new treatment for the control of serum phosphorus in patients with chronic kidney disease (CKD) on dialysis. Elevated serum phosphorus levels or uncontrolled hyperphosphatemia leads to development of secondary hyperparathyroidism, renal bone disease, calcification of vascular and nonvascular tissues, and cardiovascular disease. It is a calcium-free and aluminium-free nonabsorbed polymer phosphate binder, it does not cause calcium and aluminium toxicity. When taken with meals it inhibits intestinal absorption of ingested phosphate.

Patients with end-stage renal disease (ESRD) retain phosphorus and can develop hyperphosphatemia. High serum phosphorus can precipitate serum calcium resulting in ectopic calcification. When the product of serum calcium and phosphorus concentrations (Ca x P) exceeds 55 mg2/dL2, there is an increased risk that ectopic calcification will occur. Hyperphosphatemia plays a role in the development of secondary hyperparathyroidism in renal insufficiency. An increase in parathyroid hormone (PTH) levels is characteristic of patients with chronic renal failure. Increased levels of PTH can lead to osteitis fibrosa, a bone disease. A decrease in serum phosphorus may decrease serum PTH levels. Treatment of hyperphosphatemia includes reduction in dietary intake of phosphate, inhibition of intestinal phosphate absorption with phosphate binders, and removal of phosphate with dialysis. Sevelamerum taken with meals has been shown to decrease serum phosphorus concentrations in patients with ESRD who are on hemodialysis. In vitro studies have shown that the capsule and tablet formulations bind phosphate to a similar extent. Sevelamerum treatment also results in a lowering of low-density lipoprotein (LDL) and total serum cholesterol levels.

Uses

Sevelamerum Hydrochloride is used for the reduction of serum phosphorus in patients with end-stage renal disease (ESRD).

Sevelamerum is also used to associated treatment for these conditions: Hyperphosphataemia

How Sevelamerum works

Sevelamerum prevents hyperphosphatemia by binding to dietary phosphate in the gut, preventing its absorption and thus decreasing serum parathyroid hormone levels.

Dosage

Sevelamerum dosage

Patients not taking a Phosphate Binder: The recommended starting dose of Sevelamerum is 800 to 1600 mg, which can be administered as two to four 400 mg Sevelamerum tablets, with meals based on serum phosphorus level. Renophos 400 Recommendation for the patients with hyperphosphatemia is given below-

Starting dose of Renophos for dialysis patients not taking any phosphate binder:

  • Serum Phosphorus >5.5 and <7.5 mg/dL: 800 mg (2 tablets) three times daily with meals
  • Serum Phosphorus ≥7.5 and <9.0 mg/dL: 1200 mg (3 tablets) three times daily with meals
  • Serum Phosphorus ≥9.0 mg/dL: 1600 mg (4 tablets) three times daily with meals

Starting dose for dialysis patients switching from calcium acetate to Sevelamerum:

  • Calcium Acetate 667 mg (1 tablet): Sevelamerum 800 mg (2 tablets)
  • Calcium Acetate 1334 mg (2 tablets): Sevelamerum 1200 mg (3 tablets)
  • Calcium Acetate 2001 mg (3 tablets): Sevelamerum 2000 mg (5 tablets)

Dose titration guideline:

  • Serum Phosphorus >5.5 mg/dL: Increase 400 mg (1 tablet) per meal at 2 week intervals
  • Serum Phosphorus 3.5-5.5 mg/dL: Maintain current dose
  • Serum Phosphorus <3.5 mg/dL: Decrease 400 mg (1 tablet) per meal

Dose titration for all patients taking Sevelamerum: Dosage should be adjusted based on the serum phosphorus concentration with a goal of lowering serum phosphorus to 5.5 mg/dl or less. The dose may be increased or decreased by one tablet per meal at two week intervals as necessary.

Side Effects

Sevelamerum may cause dyspepsia, peritonitis, diarrhea, nausea, constipation, pruritus, abdominal distension, vomiting, fatigue, anorexia, arthralgia and less commonly ileus, bowel obstruction and bowel perforation.

Toxicity

Sevelamerum has been given to normal healthy volunteers in doses of up to 14 grams per day for eight days with no adverse effects. Sevelamerum has been given in average doses up to 13 grams per day to hemodialysis patients. There are no reported overdosages of sevelamer in patients. Since sevelamer is not absorbed, the risk of systemic toxicity is low.

Precaution

The safety and efficacy of Sevelamerum in patients with dysphagia, swallowing disorders, severe GI motility disorders including severe constipation, or major GI tract surgery have not been established. Caution should be exercised when Sevelamerum is used in patients with these GI disorders.

Interaction

Sevelamerum has been studied in human drug-drug interaction studies with ciprofloxacin, digoxin, warfarin, enalapril, metoprolol and iron.

Food Interaction

  • Take with food.

[Moderate] ADJUST DOSING INTERVAL: Sevelamerum may decrease the oral bioavailability of concomitantly administered drugs. While clinical data are lacking for most drugs, the intestinal absorption of some may be impaired due to sevelamer's binding capabilities.

MANAGEMENT: As a precaution, drugs that can be adversely affected by alterations in blood levels should be administered 1 hour before or 3 hours after sevelamer.

Sevelamerum multivitamins interaction

[Moderate] ADJUST DOSING INTERVAL: Bile acid sequestrants and the phosphate binder, sevelamer, can decrease the absorption of fat-soluble vitamins A, D, E, and K.

In non-clinical safety studies, rats administered colesevelam at doses greater than 30-fold the projected human clinical dose developed hemorrhage in association with vitamin K deficiency.

In a crossover study involving healthy subjects, coadministration of sevelamer with calcitriol resulted in a significant reduction in bioavailability for calcitriol (calcitriol with sevelamer vs calcitriol alone: AUC 137 pg*h
Oral vitamin supplements should be administered at least 4 hours before colesevelam and either 1 hour before or 4 to 6 hours after other bile acid sequestrants and sevelamer.

Elimination Route

Not absorbed following oral administration, however no absorption studies have been performed in patients with renal disease. Sevelamerum may bind to dietary phosphates and prevent its gastrointestinal absorption when sevelamer is administered in combination with food.

Pregnancy & Breastfeeding use

Pregnancy Category C. No adequate and controlled studies have been conducted using Sevelamerum in nursing mothers. Sevelamerum should be used during breastfeeding only if the potential benefit justifies the potential risks.

Contraindication

Sevelamerum is contraindicated in patients with hypophosphatemia or bowel obstruction and in patients with known hypersensitivity to Sevelamerum hydrochloride or any of its constituents.

Acute Overdose

Over dosages of Sevelamerum in patients was never reported. Since Sevelamerum is not absorbed, the risk of systemic toxicity is low.
