Omontys

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

Omontys is a synthetic peptide attached to polyethylene glycol for the treatment of anemia. The polyethylene glycol moiety helps make the drug less immunogenic and prolongs its plasma half-life. Chemically, peginesatide is designed to mimic the pharmacological activity of erythropoietin, but is not a replica of the structure itself. Omontys consists of two 21-amino acid chains that are covalently bonded by a linker derived from iminodiacetic acid and β-alanine. FDA approved March 27, 2012.

Omontys increases the reticulocyte count and levels of hemoglobin. It also increases RBC count, hematocrit, and soluble transferrin receptor protein in a dose-dependent manner.

Uses

Omontys is used for the treatment of anemia due to chronic kidney disease (CKD) in adult patients on dialysis

How Omontys works

Omontys binds to and activates the human erythropoietin receptor and stimulates erythropoiesis in human red cell precursors in vitro.

Toxicity

The most common adverse events (≥10%) are dyspnea, diarrhea, nausea, cough, and arteriovenous fistula site complication.

Omontys Drug Interaction

Moderate: human

Volume of Distribution

IV dose, dialysis patients = 34.9 ± 13.8 mL/kg;

Elimination Route

Tmax, SubQ dose = 48 hours;
Bioavailability, SubQ dose = 46%; Omontys does not accumulate when administered every 4 weeks following intravenous or subcutaneous administration.

Half Life

IV dose, healthy subjects = 25.0 ± 7.6 hours; SubQ, healthy subjects = 53.0 ± 17.7 hours; IV dose, dialysis patients = 47.9 ± 16.5 hours;

Clearance

Systemic clearance, IV dose, dialysis patients = 0.5 ± 0.2 mL/hr•kg

Elimination Route

Omontys administered intravenously or subcutaneously is primarily excreted via urine. Most of the excreted dose is in the form of unchanged drug. Elimination from the plasma is biphasic and rapid from vascular compartments. In contrast, the drug is selectively retained in sites of erythropoiesis like the bone marrow.
