Orodispersible Film Based on Maltodextrin: A Convenient and Suitable Method for Iron Supplementation.

Orodispersible film (ODF) is an innovative dosage form used to administer drugs and nutrients, designed to disintegrate or dissolve in the oral cavity without needing water. One of the advantages of ODF is that it is suitable for administration in older people and children who have difficulty swallowing because of psychological or physiological deficiencies. This article describes the development of an ODF based on maltodextrin, which is easy to administer, has a pleasant taste, and is suitable for iron supplementation. An ODF containing 30 mg of iron as pyrophosphate and 400 µg of folic acid (iron ODF) was developed and manufactured on an industrial scale. The kinetic profile for serum iron and folic acid upon consumption of ODF compared with a Sucrosomial ® iron capsule (known for its high bioavailability) was evaluated in a crossover clinical trial. The study was conducted in nine healthy women, and the serum iron profile (AUC 0-8 , T max, and C max ) of both formulations was defined. Results showed that the rate and extent of elemental iron absorption with iron ODF was comparable to that obtained using the Sucrosomial ® iron capsule. These data represent the first evidence of iron and folic acid absorption concerning the newly developed ODF. Iron ODF was proven to be a suitable product for oral iron supplementation.
