Ferric Carboxymaltose
Reference for: Ferric Carboxymaltose. Source presentation: injection, solution. Source route: intravenous.
Mechanism of action
Ferric carboxymaltose is a colloidal iron (III) hydroxide in complex with carboxymaltose, a carbohydrate polymer that releases iron.
Pharmacokinetics
After administration of a single dose of Injectafer of 100 to 1,000 mg of iron in iron deficient adult patients, maximum iron concentration of 37 µg/mL to 333 µg/mL were obtained respectively after 15 minutes to 1.21 hours post dose. The volume of distribution was estimated to be 3 L.
The iron injected or infused was rapidly cleared from the plasma, the terminal half-life ranged from 7 to 12 hours. Renal elimination of iron was negligible.
After administration of a single dose of Injectafer 15 mg/kg in pediatric patients 1-17 years of age, the maximum concentrations ranged between 124 and 418.1 μg/mL and the median time to maximum concentration was 7 minutes. The elimination half-life of Injectafer in pediatric patients was approximately 9.7 hours. The total median 72-hour exposure (AUC0-72h) after a single dose of Injectafer 15 mg/kg in pediatric patients was 4,529.7 μg∙h/mL while the median exposure after a single dose of 1,000 mg in adults was 5,875.3 μg∙h/mL.
