Associated Conditions
Pharmacodynamics
When measured using positron emission tomography (PET), the red cell uptake of 59-Fe and 52-Fe from INJECTAFER ranged from 61% to 99%. In patients with iron deficiency, the red cell uptake ranged from 91% to 99%. In patients with renal anemia, the red cell uptake ranged from 61% to 84%.
Mechanism of Action
Ferric carboxymaltose is a colloidal iron (III) hydroxide in complex with carboxymaltose, a carbohydrate polymer that release iron.
Absorption
When a single dose of 100 to 1000 mg of iron was given to iron deficient patients, the maximum serum concentration (Cmax) was 37 μg/mL to 333 μg/mL. These levels were obtained 15 minutes to 1.21 hours post dose (Tmax).
Volume of Distribution
