Iodine deficiency is a public health problem that is easily prevented in many countries through having a salt iodization program. However, the World Health Organization (WHO) recommends that particular population groups including infants and young children have a sufficient level of daily iodine intake, while also reducing salt consumption in their diet. While many iodine supplements are available, swallowing tablet supplements is physically difficult for young children; thus, there is a need for the development of novel iodine delivery systems for pediatric patients. In this study a novel, ultrarapidly dissolving, nanofiber-based orodispersible film formulation containing iodine which is constructed from nanofibers was manufactured using an electrospinning technique. The potassium iodate (KIO3)-loaded poly­(ethylene oxide) (PEO) fiber orodispersible films dissolve within seconds on wetting (applying on the tongue) without the need for the consumption of water. The electrospinning process and KIO3 loading did not alter the crystallinity and conformation of PEO. With high loading, KIO3 nanocrystals are present in the fibers. This formulation design allows easy administration of iodine for preventing childhood iodine deficiency. We have also described a novel and easy method for producing and harvesting nanocrystals of inorganic salts that can be potentially adopted for use in other relevant fields.
